A Note Before We Begin

Dear founder running the numbers,

I have been on both sides of this calculation. Eleven years ago I built the pro forma for what became Young Innovators Academy on a yellow legal pad at my kitchen table. It was wrong. Not in any one place — wrong in aggregate. I missed the teacher-cost ratio by about eight points, the build-out by about forty percent, and the time to break-even by fourteen months. The school still worked, because some of those errors offset each other and because the underlying market was generous. The point is that I am not writing this book to scold founders who get the numbers wrong on their first pass. I am writing it because I got them wrong on mine.

This book is the financial conversation that almost nobody in pre-K has honestly. The conferences are heavy on inspiration and light on a P&L. The Facebook groups are heavy on "follow your passion" and light on "show your spreadsheet." The first piece of advice a hopeful founder gets is do what you love and the money will follow. That advice is not exactly wrong, but it is dangerous as a primary financial model. The money does not follow. The money runs on rules.

The rules are in this book. They are not complicated — they fit on three pillars (Chapter 2). The pro forma template in Chapter 8 is the document I now build for every consulting client in their first week. It is yours, free, with no email gate. Use it.

If you are pre-operations, run the math here twice before you sign a lease. If you are already operating, run it once on your current school. If the math doesn't close, the rest of the book is about what to do.

HOW TO READ THIS BOOK

The book is sequenced as a financial diligence process. If you have not yet signed a lease, read all of it in order; you will save yourself somewhere between $40,000 and $300,000 doing so. If you are already operating, jump to Chapter 2 (The Three Numbers) first, run your own school against it, then come back. If you are deciding right now whether to open at all, read Chapter 9 (The Walk-Away Number) tonight before you make any other decision.

Step 1

LOOK

Run your school (real or proposed) against The Three Numbers in Ch 2. Note where you fail the thresholds.

Step 2

BUILD

Fill out the pro forma template in Ch 8. Two years, monthly. Honestly. Show it to someone who will challenge you.

Step 3

STRESS-TEST

Apply the Walk-Away Number (Ch 9). Stress the model with -20% enrollment and +15% costs. Does it still work?

Step 4

DECIDE

Open · fix the model · or walk away. Chapter 10 covers all three. Walking away is a real option.

Who this is for

You are running the numbers on a small pre-K — somewhere between 30 and 250 children at one to three campuses. You are pre-operations, or you have been operating for fewer than two years, or you are operating and just realized your unit economics do not work. You do not have a finance team. You have a spreadsheet, a passion for early childhood, and a real question about whether you can make a living doing this.

If you have a CFO on staff, this book is below your altitude. If you are running a national operator with shared services, the rules in here are correct but the math is different. For everyone else, this is exactly the book.

Introduction

The conversation nobody in pre-K has honestly.

There is a structural reason pre-K finance gets talked about so rarely in the trade press, the conferences, the trainings, and the Facebook groups. The reason is that the conversation is uncomfortable for almost everyone in the room. The aspiring founder does not want to confront how thin the margins can be. The bank lending the money does not want to highlight what a fragile business this is. The state licensing agency cares about compliance, not about whether you can pay your rent. The credential issuers benefit when more schools open, not when fewer schools open with better unit economics. There is nobody in the ecosystem who is paid to tell a founder her numbers don't work. So she finds out only after the lease is signed.

I have watched this happen at close range to more founders than I want to count. Three of them have called me crying. Each was a great teacher with a beautiful classroom philosophy who did not run the math beyond a one-page back-of-envelope. By the time the math caught up with them, they had committed to a lease, a build-out, and a staff — and the only choice left was whether to drain personal savings to bridge to break-even, or to close. Two closed. The third is still bridging.

This book is the conversation you will not get from the conference. It is the math the bank does not want to be the one to show you. It is, frankly, the document I wish someone had handed me before I signed my first lease.

The math is not complicated. It is, however, ruthless. Run it twice.

IN SUMMARY
  • Nobody in the pre-K ecosystem is paid to tell a founder her numbers don't work.
  • The conference circuit is heavy on inspiration, light on a P&L.
  • The math is not complicated. It is ruthless. Run it twice.

THE BENEFITS

A real pro forma is the cheapest insurance policy in the small-school business.

The pro forma in Chapter 8 takes about six hours to fill out honestly. It will tell you, with a high degree of confidence, whether the school you are about to open can pay you a living. If the answer is yes, you will sign the lease with a clean conscience. If the answer is no, you will have saved yourself somewhere between $50,000 and $400,000 in personal capital — which is the most useful six hours of work a founder can do in her life.

The other benefit, which founders underestimate, is what running the math does to your conversations with everyone else in the ecosystem. The landlord. The bank. Your spouse. Your future board. Once you have a real pro forma — not a back-of-envelope, but a two-year monthly model that holds up to questioning — you stop being the founder who says "I think the numbers will work." You become the founder who hands over a model. The landlord negotiates differently. The bank lends differently. Your spouse sleeps differently. The model is not just a financial tool; it is a posture.

The hidden benefit: the model is a teaching tool

Once you have the pro forma in your hands, you start to see every operational decision through its lens. A lease term you might have signed casually you now stress-test against years three and four of the model. A teacher hire you might have made on instinct you now check against the teacher-cost ratio. A tuition increase you might have avoided you now run through the model and discover it changes break-even by four months. The model trains you to think like an operator instead of like a founder. Both are necessary; only one keeps the school open.

  • Six hours on a pro forma can save $50K–$400K.
  • The model is a posture as much as a tool — landlords, banks, partners read it.
  • It teaches you to think like an operator, which is what keeps the school open.

Chapter 1

The Passion Fallacy &
Why This Math Never
Gets Run

The most common piece of advice an aspiring pre-K founder receives is some version of do what you love and the money will follow. The advice is not exactly wrong — running a pre-K is hard enough that you do need to love it. But as a primary financial model, the advice is dangerous. The money does not follow. The money runs on rules, and the rules are largely indifferent to how much you love early childhood education.

The passion-fallacy version of decision-making produces a recognizable pattern at small schools. Founders price tuition below the local market because they want to be "accessible," and then they cannot make payroll. They sign for more square footage than they need because they imagine the future, and then the rent bleeds them in years one and two. They over-hire beyond ratio because the children "deserve it," and they push the teacher cost ratio past the breaking point. They under-budget the build-out because they assume Pinterest pricing, and they run out of cash in month four. Every one of these is a passion decision dressed up as an operational decision.

▍ THE PASSION TEST
"If you cannot defend the decision in front of a stranger reading your spreadsheet, it is a passion decision — not an operational one."

The reframe is not to abandon passion. The reframe is to separate the two decisions cleanly. The school you build — the philosophy, the curriculum, the teacher culture, the parent relationships — is the passion decision and it should be everything you want it to be. The business you build around it is the operational decision and it has to obey rules. The founders who succeed are the ones who can hold both at once. The founders who fail are the ones who let the passion side make the operational decisions.

IN SUMMARY
  • "Follow your passion" is dangerous as a primary financial model.
  • The school is the passion decision. The business is the operational decision. Separate them.
  • If a decision can't be defended on a spreadsheet to a stranger, it's a passion decision.

Chapter 2

The Three Numbers
That Decide Everything

Three numbers, in combination, determine whether your school works. Every other line in your P&L is downstream of these.

Number 01
Enrollment %
≥ 85%
Filled seats ÷ licensed capacity. The volume number. Below this floor you cannot reliably produce owner income at any tuition level.
DANGER BELOW 70%
Number 02
Avg Tuition
$2,200+
Monthly tuition per enrolled child, blended across ages. The price number. Below this floor the math does not close in most US markets in 2026.
DANGER BELOW $1,800
Number 03
Teacher Cost
≤ 38%
Teacher wages as % of revenue. The margin number. Above this ceiling no amount of volume or pricing fixes the school.
DANGER ABOVE 45%

The rule is interlocked. If any two are wrong, the third cannot save you. If all three are right, even mediocre execution produces a school that pays its founder. Most small schools that fail miss on number 3 first, then number 1, and almost never on number 2.

10

HITTING EACH OF THE THREE

Each of the three numbers has its own playbook. Most operators try to fix all three at once and fix none well. The order below — fix number 3 first, then 1, then 2 — is what I run with consulting clients.

Number 03 first · Teacher cost ratio ≤ 38%

The hardest to retrofit. Comes from three places: ratios held at the licensed maximum (not above), a published comp band tied to performance (see Teachers Who Stay), and assistant-teacher density managed weekly. If you are above 42% on this metric, no improvement in the other two numbers will save you.

Number 01 second · Enrollment % ≥ 85%

The volume number. Solved by the reputation playbook in The Empty Classroom and by clean tour-to-enrollment conversion. Roughly 70% of small-school capacity gaps are reputation problems, not awareness problems. The other 30% are wrong-product-for-market problems that the pro forma will surface in advance.

Number 02 third · Avg tuition ≥ market median

Counterintuitive: this is the easiest of the three to fix and the one founders are most afraid to touch. Most small schools are priced 10–15% below where they should be. Chapter 5 walks the move.

A working example — 80-child school in Central Florida

Capacity: 80 children. Enrollment target: 68 children (85%). Blended tuition: $1,950/month. Annual revenue at target: $1.59M. Teacher cost cap: $605K (38% of revenue). At those three numbers, with rent, admin, utilities, insurance, marketing, and a reasonable owner draw, the school produces an annual net of $190K–$240K. Miss any one number by 5 points and the net drops by ~$80K. Miss any one number by 10 points and you are bleeding.

Chapter 3

The First $300K
(Not Pinterest Pricing)

The single most common founder error in pre-K finance is underbudgeting the build. Most founders go to their lender with a $150,000 startup budget; they need closer to $300,000–$350,000 to actually open and survive the first three months. The gap between those two numbers is what eats schools alive. The breakdown on the next page is what realistic 2026 numbers actually look like for a 2,500 sq ft, 80-child Central Florida school. Adjust to your market and your scale.

The line most founders skip entirely is the operating buffer — the 80–120K of cash you need on hand to cover months one through three of operations, when enrollment is at 15–35% and you are paying full teacher costs anyway. Without this line, you run out of cash in month four and start making desperate decisions: hiring underqualified teachers, accepting children outside your stated age range, cutting your safety margin on insurance. The desperate decisions are what compound into the schools you read about in the local news for the wrong reasons.

Case Study

WHO

Catalina, owner-operator, pre-operations, planning a 60-child school in Coral Gables, FL.

WHAT HAPPENED

Catalina built a startup budget on a back-of-envelope at $185,000. She had personally lined up $210,000 — $185K plus a 15% cushion she thought was generous. When we ran the realistic budget together (the version on the next page), the number came to $324,000.

THE DECISION

Rather than open underfunded and stress-bridge the gap with credit cards in month five, Catalina delayed opening by nine months. Spent the time raising $160,000 of additional capital from family and a small business loan, and renegotiating her lease for 90 days of free rent. Opened with $340,000 of available capital and reached break-even in month 14, three months ahead of her revised model.

THE LESSON

Delaying by nine months felt brutal. It was the right decision. The version of Catalina who opened on the original $185K would not have survived month six.

The build-out line is the most variable. In high-cost-of-living markets (Bay Area, NYC, Seattle, Boston), $60/sq ft is wildly low — closer to $120–$160/sq ft is realistic. In lower-cost markets you can run closer to $50/sq ft. Get a real GC quote before you set this number; do not estimate.

Chapter 4

Your Break-Even
Week (Not Date)

Most founders think of break-even as a date — a single day on a calendar when the school starts making money. It is more accurate to think of it as a week: the week your weekly revenue exceeds your weekly costs for the first time, and from which point forward the trend holds for 90 days. The shift from date to week matters because the variability around the date is wide; founders who plan for a precise date make leverage decisions that the actual variability cannot support.

The other shift founders need to make: break-even is later than you think. Most expect it at month 8–12. The honest median across the small schools I have audited is closer to month 14–18, with a long right tail. Schools that hit break-even at month 8 are outliers, usually with either a pre-existing waitlist from a family connection or a market with no competition. Plan for month 16. Be delighted if you beat it.

▍ THE BREAK-EVEN MATH
"For an 80-child school at $1,950 avg tuition, weekly break-even hits at roughly 64 enrolled children — about 80% utilization."

The implication is operationally significant. Many founders plan capacity additions (a second classroom, a new age band) before reaching their first break-even week. Do not expand before you have hit break-even and held it for 90 days. The temptation to add capacity to grow revenue is real; the math almost always reveals that adding capacity moves break-even further out, not closer in. Stack revenue on existing capacity until break-even holds, then expand.

14

THE CHART YOU SHOULD KEEP ON YOUR WALL

A representative break-even chart for an 80-child Central Florida school, opening with the budget on page 13. Two lines: weekly revenue (rising) and weekly fixed-plus-variable cost (mostly flat). The crossing point is your break-even week. The shaded area is what your operating buffer has to cover.

▍ REPRESENTATIVE 24-MONTH BREAK-EVEN PROJECTION · 80-CHILD CFL SCHOOL
Weekly revenue Weekly cost Cumulative shortfall (the buffer line on p. 13)

Two things on the chart matter more than the numbers themselves. One, the shape of the revenue curve is a sigmoid, not a straight line — enrollment lags, then accelerates, then plateaus. Plan around the lag, not the acceleration. Two, the shaded area under the break-even point is the cash you need to have on hand before opening. That is the $95K operating buffer line on page 13. Almost every founder cuts this line first. Almost every closed school cut it.

15
Chapter 5

The Tuition Decision —
You're Probably
Underpricing

Most small-school founders price tuition 10–15% below the local market because they want to be "accessible." This is the single most expensive operational mistake in the book, and one of the easiest to fix. The reasoning founders use sounds correct — if I charge less, more families can come, and we'll be full faster — and turns out to be empirically wrong in almost every market I have audited.

Three things go wrong with the underpricing strategy. One, a 10% lower price does not generate a 15% higher enrollment — it generates a 0–5% bump at best, because parents in this category are not selecting on price first. Two, the parents who do select on price first are not the parents you want — they will leave for the next $200/month savings, they will be your most-complaint families, and they will not refer. Three, the math is brutal: $200/month × 80 children × 12 months = $192,000 of foregone revenue a year. That is an entire teacher. Or your owner draw. Or both.

▍ THE PRICING MOVE
"Price at or 5–8% above the local market median. Then over-deliver against that price."

The other shift worth making: publish a registration fee, and make it non-refundable. Most small schools either skip this or refund it on request. A $350 non-refundable registration fee at 30 new families a year is $10,500 in pure margin and a powerful filter for tire-kickers. Parents who balk at a $350 registration fee are not your customer. Parents who pay it without complaint are the ones who will stay three years and refer two friends.

A working example

An 80-child school priced at $1,800/month vs $2,000/month. The $200 delta × 80 kids × 12 months = $192,000/year. After teacher cost (37%) the school keeps about $121,000 of that as net margin. That single decision — pricing 10% higher — is worth more than most of the operational improvements operators spend a year chasing.

16
Chapter 6

Lease, Build-Out &
the Deals That Quietly
Kill Schools

The lease is the document that locks in your fate more than any other piece of paper you will sign. Founders sign 10-year leases at 2,500 square feet when they could have started in 1,800 with a right to expand — a difference of roughly $60,000 a year in rent for the first three years, which is roughly your entire operating buffer. The lease negotiation is not where to save your founder energy. It is where to spend it.

Six clauses to negotiate, in this order

1. Free rent during build-out. Three to six months is standard in most markets. Do not pay rent on a space you cannot operate from. If the landlord refuses, walk; this is the most negotiable line in the lease.

2. Tenant improvement allowance. $25–$40/sq ft is typical for a new build-out. Get it written into the lease in dollars, not "to be negotiated."

3. Initial 5-year term with two 5-year renewal options. Not a flat 10-year. The renewal options give you the option to leave at year 5 if the location doesn't work, and the option to stay if it does. The landlord loses very little; you gain enormous flexibility.

4. Personal guarantee limited to the first 24 months. Landlords will ask for personal guarantees on the entire lease term. Negotiate a 24-month cap. After 24 months of operation, the school's track record is the guarantee.

5. Co-tenancy and exclusivity clauses. Right to break the lease if a major anchor leaves. Right to be the only daycare in the strip mall. Both are standard, both protect you.

6. Annual escalator capped at 3%. Many landlords push 4–5%. Cap at 3% or CPI, whichever is lower. Over a 10-year term, the difference between 3% and 5% annual escalation on a $14,000/mo lease is roughly $40,000 cumulative.

The Pinterest-pricing trap

Founders Pinterest-board the build-out — natural wood, plants, soft palettes, big windows — and discover the build costs 2–3× their budget. Plan for $80–$100/sq ft realistic, with a 15% contingency on top. A 2,500 sq ft school at $90/sq ft = $225,000. Add 15% contingency = $259,000. That is why the startup budget in Chapter 3 starts at $312K. The Pinterest aesthetic can be earned over time. The contingency cannot.

17
Chapter 7

Capacity Math:
Why 24 Kids Is
Harder Than 60

A counterintuitive fact that has cost founders more money than I can responsibly tally: a small pre-K with 24 children has worse unit economics than a 60-child school. The instinct is the opposite — smaller school, smaller costs, easier to fill. The math says otherwise. Fixed costs do not scale down. Owner-director labor is fixed regardless of size. Insurance, licensing, lease, utilities, basic admin — fixed. Teacher cost scales linearly with kids inside ratio bands. Marketing cost is roughly fixed. So gross revenue scales with kids, but the fixed cost base eats the small school.

The breakeven enrollment floor for most small schools is around 45–55 children. Below that, the owner cannot make a living without working full-time as a teacher and running the business — which is the lifestyle model, and is a real choice, but is not the same as running a business. Above 60 children, fixed costs are spread across enough revenue to produce a real owner draw plus margin for reinvestment.

▍ THE TWO VIABLE SCALES
"24 kids is a lifestyle. 80 kids is a business. 45 kids is purgatory. Pick one of the first two."

Two scales work. The lifestyle model is 18–28 children with the owner in the classroom every day, 1–2 staff, modest overhead, a real ceiling on income, and a life-balance ceiling on hours. Some founders thrive here, and the model is legitimate. The business model is 60–120 children with proper organizational structure, an operations director or admin, and the owner working on the school rather than in it. The middle — 35–55 children — is purgatory. Too small to support real org structure. Too big for one person to teach and run. Founders accidentally end up here because they "started small" and then never raised the capital to reach the business-model scale.

IN SUMMARY
  • Small does not mean cheap. Fixed costs eat tiny schools.
  • Two viable scales: ~24 kids (lifestyle) or 60+ (business). The middle is the trap.
  • Decide which scale you are choosing before you sign the lease.
18
A Note On Scale
"
The size you choose determines the life you live. Twenty-four kids is a lifestyle. Eighty kids is a business. Forty-five kids is purgatory. Pick one of the first two — and pick before you sign the lease, not after.
"
Marnie · Raising Innovators Podcast, Ep. 47

The most common version of the "accidentally in purgatory" school I see is the founder who opened with an aspirational 60-child capacity, ran into reputation and enrollment headwinds, settled at 38 children, and then could not find a way back. The fixed costs were built for 60. The revenue was sized for 38. The owner could not exit the role of head teacher. Five years later she was tired, breaking even, and asking the question this book exists to answer.

Two paths out of purgatory: shrink the school deliberately to 24, lay off most staff, become the lead teacher (lifestyle model) — or raise outside capital and aggressively recruit to 60+ (business model). Both are uncomfortable. Both work. Staying in purgatory is the path that ends with the school closing.

Chapter 9

The Walk-Away
Number — When
to Not Open

The conversation founders avoid most completely is the walk-away conversation. Almost nobody opens a school with a clearly defined number that, if exceeded, triggers a closing decision. That absence is what produces the founders who lose their homes, their retirement, and sometimes their marriages bridging a school that the math was never going to support.

The walk-away number is the maximum amount of personal capital you will inject into the school after opening before deciding it isn't working. It is decided before you sign the lease, written down, shared with a spouse or trusted advisor, and treated as binding. For most small-school founders this number should be somewhere between $50,000 and $100,000. Above $100,000 of personal capital injected post-opening, you are almost always bridging a school whose underlying unit economics do not work — and the bridge is being paid for by your retirement fund.

▍ DEFINE THIS BEFORE YOU SIGN THE LEASE
$50K–$100K
The maximum personal capital you will inject into the school after opening before triggering a close decision. Written down. Shared. Binding. Founders who define this in advance preserve their home, their retirement, their relationship. Founders who refuse to define it are the ones who lose everything.

The reason this number is so important is psychological more than financial. Once a school is open, founders fall in love with the rooms, the children, the teachers they have hired — and the love makes it almost impossible to walk away even when the math says they should. The walk-away number, set before any of that love exists, is the only protection a founder has against herself. When the number is hit, the rule is binding. Most founders who set the rule before opening end up never needing it. Most founders who refuse to set it end up exceeding any number they would have set.

IN SUMMARY
  • Set a walk-away number in writing before signing the lease.
  • $50K–$100K of personal capital injected post-opening is the typical cap.
  • Setting it protects you from yourself once you fall in love with the rooms.

What to Do With the
Numbers Once
You Have Them

You have filled out the pro forma. You have stress-tested it. You have set a walk-away number. The model produces one of three outcomes. The temptation, when the model produces the third outcome, is to ignore it. Do not.

1 · The math closes

You meet the three numbers within reasonable thresholds, you have the operating buffer, your break-even week lands inside month 20, and your walk-away exposure is bounded. Open. Now your focus shifts entirely to execution: tours that convert, hires that stay, reputation that compounds. Read The Empty Classroom and Teachers Who Stay next.

2 · The math is close but not quite

Usually fixable with one of three moves: a smaller starting space (drop from 2,500 to 1,800 sq ft, defer expansion), a higher tuition (the move in Ch 5 is almost always available), or a tighter teacher cost ratio (Ch 6 of Teachers Who Stay). Re-run the model with one change at a time. Most "close but not quite" schools become workable schools with two corrections.

3 · The math does not close

Walk away. Try a different location, a different scale, or a different timing. The school you do not open is the most valuable lesson you will ever buy for $300,000 — because you did not buy it. Founders who walk away at the model stage almost always re-emerge two to four years later in a stronger market with a better plan and open a school that works.

10 Financial Mistakes
Founders Make

In rough order of damage. I have made at least four. Most founders make at least six.

01

Underbudgeting the build-out

Pinterest pricing instead of GC quotes. The $80K shortfall in month two is the most common school-killer in the category.

02

Taking too much square footage

Aspirational space at year-one rent costs you the entire operating buffer. Start at the smallest viable footprint with a right to expand.

03

Signing a 10-year lease with no renewal options

5+5 structure protects you. A flat 10 locks you in even if the market shifts beneath you.

04

Pricing below market "for accessibility"

The most expensive passion-decision in the book. $200/mo × 80 kids × 12 = $192K/yr of foregone revenue.

05

Skipping the operating buffer

Months 1–3 cash is not optional. Without it, you run out at month four and start making desperate decisions.

06

Hiring beyond ratio because "the children deserve it"

Pushes teacher cost ratio past 42% and structurally bleeds the school. Stay at ratio. Pay above-market for better teachers within ratio.

07

Uncapped personal guarantee on the lease

One bad year and the landlord can come after your house. Cap at 24 months. Always.

08

Treating marketing as a cuttable line item

When founders panic, marketing is the first thing cut. Marketing is the line that fills the rooms. Cut director draw before you cut marketing.

09

No defined walk-away number

The Ch 9 number, set in writing, before opening. Founders who refuse to set this lose more than founders who set it and never need it.

10

Refunding registration fees on request

The non-refundable fee filters tire-kickers and produces real margin. Refunding it teaches parents that the school's stated policies are negotiable.

23

THE WEEKLY FINANCIAL DASHBOARD

Eight numbers. One sheet. Reviewed every Monday morning before any other meeting on your calendar. Most founders measure quarterly and discover problems six months late. Weekly review is what separates schools that hit break-even on time from those that miss by a year.

01 · Weekly enrollment count
Total enrolled children at end of week. Track net adds and net drops separately.
Target: ≥85% of capacity
02 · Weekly tours scheduled
New tours booked this week, source-tagged (web, referral, mom-group, employer, walk-in).
Goal: 8–12/wk per campus
03 · Tour-to-enrollment %
% of tours that convert to enrollment within 14 days.
Floor: 35% · Goal: 55%+
04 · Teacher cost ratio (rolling 4-wk)
Wages ÷ revenue, rolling four-week average. The most predictive single number you watch.
Cap: 38% · Danger: 42%+
05 · Cash on hand (in months)
Cash ÷ monthly operating cost. Tells you how long you can run if revenue stops today.
Floor: 2 mo · Goal: 4+ mo
06 · Weeks to break-even (modeled)
From the pro forma, recalculated weekly with current enrollment trajectory.
Stable or declining each week
07 · Avg tuition per enrolled child
Total monthly tuition ÷ enrolled children. Watch for drift below your target.
≥ market median
08 · Marketing cost per new enrollment
All-in marketing spend ÷ new enrollments this month.
Goal: under $180

Number 4 is the single most predictive of these. When teacher cost ratio drifts above 42% for three consecutive weeks, the school is on a path that cannot self-correct without an active intervention. Read your dashboard. Catch the drift in week one, not month four.

WORK WITH MARNIE

Three tiers, all flat-fee at the lower tiers, designed around the diligence and operations sequence in this book. Tier 2 — the 90-day Pre-Open Strategy engagement — is the recommended starting point for pre-operations founders and is, candidly, the engagement I wish I had hired for myself eleven years ago.

Tier 1
PRO FORMA REVIEW
30 days · flat fee

You build the pro forma. I tear it apart. We identify the 3–5 most dangerous assumptions. One on-site (or video) working session. Designed as a clean off-ramp if Tier 2 isn't right yet.

★ RECOMMENDED
Tier 2
PRE-OPEN STRATEGY
90 days · flat fee

Tier 1, plus full pro forma build, lease negotiation support, vendor & build-out review, walk-away number set in writing, and a Stage 1 reputation setup using The Empty Classroom framework — all before opening.

Tier 3
FOUNDING ADVISOR
12 months · monthly retainer

Tiers 1 + 2, plus monthly board-level reporting, the full operational sequence through opening, the first hiring cycle run together, and ongoing strategic support through your first break-even week.

Engagements start with a 25-minute free audit conversation. We talk through your draft pro forma and the three numbers in Chapter 2. If it's a fit, we go. If it's not, you walk away with a one-page action plan.

MARNIE'S BOOKS

Six books with Gryphon House across eleven years. The Basics of Starting a Child-Care Business is the direct companion to The Pre-K Pro Forma — read them together if you are pre-operations. Together they are the closest things to a small-school MBA you can put on a single shelf.

Starting is where this pro forma philosophy first appeared in print. Leading picks up the operations after you've opened. Pair them.

KEEP LEARNING

Raising Innovators

A weekly podcast for school founders, directors, and the operators trying to do this work better. Tuesday episodes — many of them on the financial side of running a small school.

Listen on: Apple  ·  Spotify  ·  YouTube

Recommended episodes for this book: the lease negotiation teardown (Ep. 42), the underpricing conversation with a Florida operator (Ep. 47), and the "founder who walked away" story (Ep. 53).

YIA Operator Days

The three Young Innovators Academy campuses host quarterly Operator Days. A half-day of working sessions covering the pro forma model live, lease-and-build review, and a Q&A on whatever stage of diligence you are in.

Campuses: Winter Garden, Winter Park, Oviedo (Central Florida).

If you do three things this week
  1. Download the pro forma template (marnieforestieri.com/pro-forma). Fill out month 1–12. Honestly.
  2. Run your draft against the three numbers in Chapter 2. Mark where you fail the thresholds.
  3. Define your walk-away number (Ch 9). Write it down. Tell your spouse or advisor.

The third one takes ten minutes and saves more founders from financial harm than the other two combined.

RESOURCES & FURTHER READING

Curated for the financial side specifically. The pro forma & lease tools section is unique to this playbook.

PRO FORMA & FINANCIAL TOOLS

LEASE & REAL ESTATE

  • Crexi — commercial real estate listings; sortable by sq ft & market.
  • LoopNet — second most useful listing platform; good for tenant rep search.
  • Hire a tenant-rep broker — not the landlord's broker. The fee is paid by the landlord. There is no reason to negotiate without one.
