Instructor pay is the largest controllable cost in most fitness studios. Unlike rent or insurance, pay structure is a design decision — one that compounds across hundreds of classes per year. A model that works at 15 students per class can be punishing at 5, and overpaying at 25.
The comparator above lets you enter your actual numbers and see all three models evaluated simultaneously: flat pay, pure per-head, and a hybrid base-plus-per-head structure. No spreadsheet. No back-of-napkin math. Just the outcome at your current attendance.
How to read the comparison table
The table shows three columns that matter: pay per class, pay as % of revenue, and studio margin. The model with the highest studio margin is flagged as best for your current attendance level — but the right answer changes as attendance changes.
Break-even attendance shows the headcount at which studio margin hits zero for each model. For flat pay, it's straightforward: the number of students needed so that total class revenue equals the flat rate. For hybrid, it factors in both the base and per-head components. For pure per-head, margin is proportional to attendance (as long as per-head rate is below revenue per head) — meaning it never hits zero in isolation, but can compress quickly.
Three tips for choosing the right pay structure
1. Match pay model to class maturity. New classes with small, growing attendance benefit from hybrid — the base protects the instructor during the build phase, and the per-head incentive aligns their interest in growing the class with yours. Established, high-attendance classes can often support flat pay with better margin.
2. Use break-even as a minimum attendance policy. If your flat-pay break-even is 8 students and you're averaging 6, the class is running at a structural loss on instructor cost alone before you account for space and overhead. That's the number to fix — through marketing, scheduling, or format change.
3. Audit quarterly, not annually. Class attendance shifts with seasons, instructor changes, and format trends. A pay model that worked in Q1 may be eroding margin by Q3. Schedule a quarterly review of pay as % of revenue for each class type. Five minutes of analysis per quarter is worth far more than the hour you'll spend resolving payroll disputes after the fact.
What this calculator doesn't cover
This tool models a single class in isolation. It doesn't account for: instructor tenure bonuses, tip distribution, class prep time, or the cost of cancelled classes with minimum pay guarantees. Those factors matter — but they belong in your full payroll model, not a per-class margin calculator. Start here to get the structure right, then layer in the exceptions.

Frequently asked questions
Which instructor pay model is best for low-attendance classes?+
Hybrid (base + per-head) typically performs best when attendance is unpredictable or skews low. The fixed base protects the instructor while the per-head component ties cost to actual revenue generated. Flat-only pay at low attendance can consume most or all of your margin on a bad week.
At what attendance does flat pay become the best model?+
It depends on your specific rates, but flat pay generally wins on margin once attendance climbs high enough that total revenue significantly exceeds the flat amount. Run the comparator with your actual numbers and watch the 'Studio margin' column — the crossover point will be visible.
Should I tell instructors which model I'm using?+
Yes. Transparency reduces turnover. Top instructors who understand they're paid fairly for their class size are more likely to stay and build the class than to feel penalized for low turnout under a pure per-head model. Hybrid with a guaranteed base is the most retention-friendly structure.
