The Break-Even Headcount: How Many Students Your Kumon Centre Actually Needs Before You Take Home a Dollar
Kumon’s per-student royalty means your profit is a headcount problem, not a pricing problem. Here is the math most discovery days skip.
You are looking at Kumon because the entry cost is manageable and the model is simple. Both of those things are true. But the question that actually determines whether you make money is not how much the franchise costs to open — it is how many students you need enrolled, paying, and showing up every week before your centre covers its own expenses and starts paying you. That number is higher than most prospective owners expect, and the royalty structure is the reason.
This article builds the break-even model from first principles so you can stress-test it against your own market before you sign anything.
The Royalty Is a Headcount Tax, Not a Revenue Share
Most franchise systems take a percentage of gross revenue. Goddard charges 7%. Primrose charges 7%. Mathnasium charges 10%. If you raise prices or add services, the royalty goes up proportionally — but so does your gross, so the margin relationship stays roughly constant.
Kumon does not work that way. Kumon charges a flat fee of approximately $38 per student per subject per month, with the actual figure falling in the $38–$42.75 band based on 2025/2026 disclosure data. That means:
- A student enrolled in math only costs you ~$38/month in royalty.
- A student enrolled in both math and reading costs you ~$76/month in royalty.
- Raising your tuition from $150 to $175 does not change the royalty by a cent.
The structural consequence is important: your royalty bill is driven entirely by headcount and subject mix, not by revenue. Every new enrolment adds a fixed cost before it adds any margin. And if that student takes both subjects, you pay the royalty twice — even though the incremental labour and space cost of a second worksheet packet is close to zero.
This is not inherently bad. It means that at scale, high-tuition markets keep more of every dollar. But at low enrolment, the per-student royalty eats a larger share of a thinner revenue stream, and that is exactly where new centres live for their first year.

The Fixed Cost Floor: What a Kumon Centre Actually Costs to Keep Open
Before a single student walks in, you are paying to keep the lights on. Here is what a typical Kumon centre’s monthly overhead looks like, based on publicly available lease data and Bureau of Labor Statistics wage figures:
Rent for 1,000–1,500 square feet of retail or strip-mall space: $2,000–$5,000/month. The range is wide because a centre in suburban Ohio and a centre in coastal California are not the same business. Kumon centres do not need Class A retail — they need visibility, parking, and proximity to schools. But even B-grade retail in a mid-cost market runs $2,500–$3,500.
Part-time instructional assistants: 2–4 staff members at $15–$18/hour, each working 15–20 hours per week. That is $1,800–$5,760/month in labour before payroll taxes. You are the lead instructor; they grade worksheets, manage the room, and keep the workflow moving during peak afternoon hours.
Insurance, utilities, materials, and marketing: $800–$1,500/month combined. This includes general liability, the Kumon worksheet supplies, basic utilities, and whatever local marketing you do beyond what the brand provides.
Total fixed monthly overhead: roughly $5,500–$11,000 before any royalty payment. That is the number your enrolment has to clear before you see a dollar. The low end is a single-assistant centre in a cheap market. The high end is a staffed-up centre in an expensive metro where rent alone eats $4,000.

Building the Model: Students × Subjects × Months
Now we can build the actual break-even calculation. The inputs:
- Average monthly tuition: ~$150–$200 per student, varying by market. Some centres in high-cost areas charge $200+ per subject; others in competitive suburban markets sit closer to $130–$150.
- Average subjects per student: 1.3–1.5. Math is the anchor; roughly 30–50% of families add reading.
- Gross revenue per student: $195–$300/month (tuition × average subjects).
- Royalty per student: $49–$64/month (1.3–1.5 subjects × ~$38 per subject).
- Net revenue per student after royalty: ~$146–$236/month.
With those ranges, here is what the monthly P&L looks like at different enrolment levels. This table uses a mid-range assumption: $175 average tuition per subject, 1.4 average subjects, $53 royalty per student, and $8,000 monthly overhead (a realistic mid-market centre):
| Students | Gross Revenue | Total Royalty | Overhead | Monthly Net |
|---|---|---|---|---|
| 30 | $7,350 | $1,590 | $8,000 | −$2,240 |
| 50 | $12,250 | $2,650 | $8,000 | $1,600 |
| 75 | $18,375 | $3,975 | $8,000 | $6,400 |
| 100 | $24,500 | $5,300 | $8,000 | $11,200 |
| 125 | $30,625 | $6,625 | $8,000 | $16,000 |
| 150 | $36,750 | $7,950 | $8,000 | $20,800 |
At 30 students you are losing money. At 50 you are technically positive, but $1,600/month is not a salary — it is a part-time hobby that owns all your afternoons. The realistic break-even for a mid-market Kumon centre is somewhere between 40 and 75 students, depending on your rent, your tuition, and your subject mix.
At 100+ students the model starts to look like a real business. At 150 it is genuinely attractive. But getting there is the problem.
Note: Kumon does not publish an Item 19 financial performance representation in its Franchise Disclosure Document. That means there is no franchisor-verified revenue, expense, or profit data for existing centres. Every earnings figure you see — including the ranges in this article — is derived from third-party estimates, public filings, and operator-reported data. Treat it as directional, not precise.
The Enrolment Ramp Nobody Talks About
A new Kumon centre does not open with 75 students on day one. It opens with whatever your pre-opening marketing generated — often 10–25 students — and builds from there.
This is the part of the model that determines whether you survive the first year. The economics above assume steady-state enrolment. But between your grand opening and steady state, you are burning cash every month, and the gap between your overhead and your revenue is coming out of your working capital.
How long does the ramp take? Kumon does not disclose ramp data (again, no Item 19). Industry estimates and franchisee discussion forums suggest 6–18 months to reach 75+ students, with wide variance based on:
- Market density: How many school-age children live within a 10-minute drive?
- Competition: How many other Kumon centres, Mathnasium locations, and private tutors are already serving the area? The competitive landscape analysis covers this in detail.
- Your marketing effort: Kumon provides brand awareness, but local enrolment is driven by local outreach — school partnerships, community events, word of mouth.
- Retention: Kumon’s worksheet-based model has natural attrition. Students plateau, parents lose patience, or families move. A centre that enrols 10 students per month but loses 5 is growing at half the rate it appears.
If you assume a 12-month ramp to 75 students with a linear build, you are averaging around 37 students for the year. At the mid-market numbers above, that is roughly breakeven on a monthly basis — meaning your first year’s take-home pay is approximately zero, and any month where enrolment dips below the line comes out of savings.
This is where under-capitalised owners fail. The total initial investment for a Kumon franchise is $101,630–$233,780 (the figure two independent sources agree on; the FDD has not been read directly for this article). That range includes the franchise fee, buildout, equipment, and initial working capital. But if your working capital allocation assumed a 3-month ramp and reality delivers a 12-month ramp, you are nine months short.
What This Means for Your Financing
The investment range — $101,630–$233,780 for a Kumon franchise — sits in a bracket where multiple financing paths are viable. That is one of the model’s genuine advantages. You are not borrowing $500,000 for a Goddard buildout or $3 million for a Primrose ground-up construction; you are financing a retail lease and some furniture.
SBA microloans max out at $50,000 and are designed for exactly this scale of business. The SBA 7(a) program covers larger amounts if your total need exceeds the microloan ceiling. Both require a business plan, and both will want to see how you model the enrolment ramp.
Capital advisors like Lendesca model franchise-specific break-even scenarios, which matters here because Kumon’s per-student royalty structure makes the math different from a percentage-royalty franchise. A lender evaluating a Mathnasium loan models revenue risk; a lender evaluating a Kumon loan needs to model enrolment risk, which is a different curve.
The per-student model also means your debt service is enrolment-dependent in a way that percentage-royalty franchises are not. If you miss the enrolment ramp by three months, you do not just earn less — you may miss loan payments, because your fixed costs (including the loan) do not flex with your headcount. This is the core financial risk of the model, and it is worth understanding clearly before you sign a personal guarantee.
For comparison, childcare franchises like Primrose or Goddard carry initial investments of $500,000–$5,500,000+ (varying by whether you are leasing or purchasing and constructing a facility), but their revenue is also proportionally larger. The loan-to-revenue ratio is similar; the absolute stakes are not. Whether that is better or worse depends on your risk tolerance and your capital. The financing options page breaks down the available paths.
The Number That Matters
Franchise sales materials will tell you about the brand, the method, the 65-year track record, the thousands of centres worldwide. Those things are real. But none of them pay your rent in month four when you have 28 students and your overhead is $8,000.
The number that matters is your break-even headcount — and you now have the framework to calculate it for your specific market:
- Get your actual rent for the specific spaces you are considering. Do not use national averages.
- Price your labour at local wages, not the federal minimum. Check the BLS Occupational Employment and Wage Statistics for your metro area.
- Survey local tuition by calling the three nearest Kumon centres as a parent. Tuition is not published centrally; it varies by location.
- Model the ramp conservatively. If you think you will hit 75 students in 6 months, model for 12. If you think 12, model for 18. Your working capital reserve needs to cover the gap between optimism and reality.
- Stress-test the subject mix. If your model assumes 1.5 subjects per student but your market delivers 1.2, that is a 20% revenue reduction with almost no change in overhead.
The franchise itself is straightforward. The method works. The brand is recognised. The question is not whether Kumon is a good educational model — it is whether the unit economics work in your specific market, at your specific cost structure, with realistic enrolment assumptions. Build the spreadsheet. Run the numbers. If they work at pessimistic inputs, you have a business.
