Most school owners track two numbers: how many students they have and what is in the bank. Both are lagging indicators. By the time either one moves enough to notice, the thing that caused it happened three months ago. These are the twenty numbers that tell you what is happening now, each with its formula and what to do when it is weak.
Read this first: we are not giving you targets
Every published benchmark in this industry comes from a company selling something to the schools being benchmarked, from a self-selected sample, or from schools that define their terms differently from one another. A target you cannot audit is worse than no target, because it tells you how to feel without telling you anything true.
So: calculate all twenty for the last three months. That is your baseline. Improve against it, recalculate quarterly, and judge yourself against your own trend. Where a number has a structural logic that beats a benchmark — and several do — this guide gives you the logic instead.
Acquisition: seven numbers
| Number | Formula and what it tells you |
|---|---|
| 1. Leads | count — enquiries in the period. Meaningless until you write down what counts as one and stop changing it. A walk-in referral either is a lead or is not; pick one. |
| 2. Contact rate | leads reached ÷ leads received — whether you get hold of people at all. If this is your weak link, nothing downstream can be fixed. |
| 3. Time to first contact | median minutes from enquiry to a human — not to an autoresponder. The single most improvable number in the funnel. |
| 4. Appointment rate | appointments booked ÷ leads reached — whether whoever answers the phone knows how to book. |
| 5. Show rate | appointments attended ÷ booked — whether your bookings survive to the day. Weak here means confirmation, not conversion. |
| 6. Intro-to-enrollment | enrollments ÷ intros delivered — whether the lesson and the conference work. |
| 7. Cost per enrollment | marketing spend ÷ enrollments — the only acquisition cost that matters. Cost per lead is a vanity metric; cheap leads that do not enroll are expensive. |
Retention: five numbers
| 8. Active students | count of students who attended in the last 30 days — note that definition. Students who pay but do not attend are not active; they are a cancellation that has not happened yet. |
| 9. Monthly attrition | students lost ÷ students at the start of the month. Track the count, and separately track how long each one had been enrolled. |
| 10. Thirty-day retention | still attending at day 30 ÷ enrolled that month — the single best predictor of whether a cohort will still be there at a year. |
| 11. Average length of stay | sum of months enrolled for everyone who left ÷ number who left. Depressing to calculate once and clarifying thereafter. |
| 12. Attendance rate | classes attended ÷ classes available to that student. Falling attendance precedes cancellation by weeks. This is your early warning system and almost nobody runs it. |
If you only add one number to your school this quarter, add attendance rate per student. Cancellation is a lagging indicator of a decision that was made several missed classes earlier. Attendance is the leading one, and it is the only number on this list that lets you intervene before the money is gone.
Money: eight numbers
| 13. Collected revenue | money actually received — not billed, not contracted. The gap between billed and collected is where schools quietly bleed. |
| 14. Recurring revenue | collected revenue from memberships — the part that arrives without anyone selling anything. The health of the business is this figure, not the total. |
| 15. Revenue per student | collected revenue ÷ active paying students. The most diagnostic single number in the school. A falling figure with rising headcount means you are discounting. |
| 16. Declined and failed payments | value of failed transactions ÷ value billed. Usually invisible, always recoverable, and almost never worked. |
| 17. Payroll percentage | total payroll ÷ collected revenue, with the owner’s own compensation shown separately. Two schools with identical percentages are in completely different positions if one of them is paying the owner nothing. |
| 18. Rent percentage | rent ÷ collected revenue — but see below, because the percentage is the wrong frame. |
| 19. Marketing percentage | marketing spend ÷ collected revenue. Judge it against cost per enrollment and lifetime value, not against a target percentage. |
| 20. Operating profit | collected revenue − all costs including a market-rate salary for the owner. If the owner’s labour is free, the school is not profitable; it is subsidised. |
The three numbers people most want a benchmark for
Rent, payroll and marketing. Here is the structural logic, which is more useful than a borrowed percentage.
Rent is a fixed cost, so the percentage lies to you. A school paying 25% of revenue in rent at 120 students is paying 12.5% at 240 students in the same building, having done nothing about the rent. The number that actually governs the decision is rent per enrolled student and, behind it, the break-even student count: fixed costs ÷ average revenue per student. That tells you how many students the lease requires before anything else is affordable. Sign a lease against that figure, not against a percentage you read somewhere.
Payroll is a capacity decision disguised as a cost. The question is not what share of revenue it consumes but what each role returns. An instructor who allows you to run two more classes has a revenue number attached; an administrator who cuts time-to-first-contact from a day to ten minutes has one too. Work out the return for each role before comparing the total to anything.
Marketing has a ceiling and it is derived, not looked up. Estimate a student’s lifetime value: revenue per student × average length of stay in months. Your acquisition ceiling is a fraction of that — how large a fraction depends on your margin and how fast you need the cash back. Then test your actual cost per enrollment against it. That is a real answer, produced from your own school, and it beats any industry average.
What to do when a number is weak
| Symptom | Where to look first |
|---|---|
| Enrollments falling, leads steady | Time to first contact, then show rate. Almost never the enrollment conversation, which is where owners always look. |
| Headcount steady, revenue falling | Revenue per student. You are discounting, or your mix has shifted to cheaper programmes. |
| Revenue steady, profit falling | Payroll and failed payments. Check declines before you cut staff. |
| High attrition at 3–5 months | Thirty-day retention and attendance rate. The loss was decided in month one. |
| Good gross revenue, no cash | Collected versus billed. Somebody is not paying and nobody is chasing it. |
| Everything looks fine, owner is exhausted | Operating profit with a real owner salary in it. The school may be paying everyone except the person carrying the risk. |
How to actually start
Not with software. With a single sheet, updated weekly, containing the seven acquisition numbers and the five retention numbers. The money numbers come from your bookkeeping monthly.
Three months of honest recording beats any dashboard bought to avoid it. Most schools that install tracking software still cannot answer the first question on this list — what counts as a lead — which is why the dashboard shows figures nobody trusts.
Frequently asked questions
What is revenue per student in a martial arts school?
Revenue per student is total collected monthly revenue divided by the number of active paying students. It is the most diagnostic single figure in a school: if headcount rises while revenue per student falls, the school is discounting its way to growth. Use collected revenue rather than billed, and count only students who have actually attended in the last thirty days.
What percentage of revenue should a martial arts school spend on rent?
The percentage is the wrong frame, because rent is fixed while revenue is not — the same lease is 25% of revenue at 120 students and 12.5% at 240. Use rent per enrolled student, and behind it the break-even student count: fixed costs divided by average revenue per student. That figure tells you how many students the lease obliges you to carry.
How do you calculate a martial arts student’s lifetime value?
Multiply revenue per student per month by the average length of stay in months, where average length of stay is the total months enrolled for everyone who left divided by the number who left. Your acquisition ceiling is a fraction of that figure, set by your margin and how quickly you need the cash returned.
What is the most important number to track in a martial arts school?
Attendance rate per student, because it is the only leading indicator on the list. Cancellation is a lagging indicator of a decision made several missed classes earlier; falling attendance gives you the chance to intervene while the student is still enrolled.
About this guide
Sources. The structure draws on the NAPMA and Martial Arts Wealth Mastery training archive, 2009–2016, in particular its “Essential Stats and Target Ratios” material and its financial control and retention system. That archive was produced for members of coaching programmes run by this magazine’s publisher. The definitions, formulas and judgements here are the journal’s.
What we have deliberately not published. Target ranges. The archive contains target ratios taught to coaching clients; publishing them as industry benchmarks would give them an authority they have not earned, because they derive from a self-selected population rather than a representative survey. This journal is working on an independent industry survey. Until it exists, benchmark against your own trailing figures.
