Most studio owners can tell you what they pay an instructor per class. Very few can tell you what a class actually costs to run. Those are not the same number, and the gap between them is where margin quietly disappears. A rate on a spreadsheet is clean. The real figure carries meeting time, admin, sub coverage, payroll tax, and the empty seats you paid for anyway. If you have never built the fully loaded cost of a single session, you are pricing your schedule on a guess.
This is not an argument for paying instructors less. Good teaching fills classes and keeps members, and that is the whole business. It is an argument for knowing the true number, because the pay model you choose does more than set cost. It shapes which classes get taught, how hard people fight for attendance, and whether your 6am on a Tuesday survives.
The three pay models, and what each one rewards
Boutique studios generally run one of three structures. The first is a flat per-class rate. The instructor gets a fixed amount whether two people show or twenty. Rates vary by market and format, but a common range sits at $35 to $80 per class depending on experience and location. Flat pay is simple and predictable. It also means your cost per head is entirely at the mercy of attendance you do not control.
The second is per head. The instructor earns a set amount for each person in the room, often $3 to $8 per head, sometimes with a minimum floor so a quiet class does not pay nothing. This ties your cost directly to revenue, which protects margin. It also pushes risk onto the instructor and can turn a slow season into a reason to leave.
The third, and increasingly the default, is the hybrid. A base rate plus a per-head bonus above a threshold. One worked example is $50 base plus $3 per head above 10 students, which lands at $65 at fifteen students and $80 at twenty. The hybrid gives instructors a floor they can count on and a reason to care about the twelfth and fifteenth booking. That is the behaviour you actually want to pay for.
The loaded cost is bigger than the rate
Here is where owners underprice their schedule. The per-class rate is the visible cost. The real one includes everything the rate does not name. Instructors routinely perform compensable work beyond class time: building playlists, messaging clients, posting about their classes, attending mandatory meetings and continuing education, and preparing the space. Employment lawyers now flag per-class pay as functionally a piece-rate system under the FLSA, one that does not by itself satisfy minimum wage and overtime obligations for W-2 staff. The off-class hours are real, and if you are not paying for them explicitly, you may still owe for them.
The stakes are not theoretical. In the Equinox California wage-and-hour matters, the company agreed to pay $36 million to resolve combined class and PAGA claims. Most studios are not Equinox, but the exposure scales down to your size, and the underlying error is the same: treating a per-class rate as if it captures the full cost of employing a person.
Then add employer payroll tax, any benefits, software, and the share of overhead the class consumes. A useful way to sanity-check the total is to look at instruction as a share of revenue. Across studios that pay for teaching rather than running owner-led classes, instructor compensation typically runs 35 to 55 percent of revenue. If your number sits above that band, either your pricing is too low or your classes are too empty, and the pay model is not the thing to blame first.
Sub coverage is a cost, not a favour
Every schedule needs cover, and cover is where the loaded cost spikes without anyone noticing. When a regular instructor is out, you often pay a premium, lose some regulars who came for that specific teacher, and spend staff time arranging the swap. A flat-rate model makes this easy to arrange and expensive to absorb, because you pay the same rate for a sub who draws half the room. A per-head model makes it cheap for you and unappealing for the sub, who inherits a cold audience for thin pay.
The hybrid handles cover better than either extreme, because the base rate makes a sub willing to take the slot and the per-head portion keeps your cost honest when the room is light. Whatever model you run, price sub coverage in advance rather than treating each instance as a one-off emergency. A schedule that depends on goodwill to stay staffed is a schedule with a hidden liability.
Pay structure is schedule design
The point most owners miss is that your pay model is a scheduling tool. Consider that most fitness instructors work part-time and are paid per class or per hour, with the median instructor earning $46,180 a year as of May 2024, or roughly $22 an hour. These are people stitching together income across studios. The model you offer decides whether your slots are worth their time.
Flat pay makes off-peak classes easy to staff, because the instructor earns the same at 6am as at 6pm. That is why studios lean on it to keep thin slots alive. But it also means nobody in the room has a financial reason to grow that class, so it stays thin. Per-head pay does the opposite. It concentrates your best instructors on your fullest classes and starves the shoulder hours, because no experienced teacher will take a 2pm for per-head pennies. Left unmanaged, per-head hollows out the middle of your timetable.
The hybrid is popular precisely because it lets you tune this. Set the base high enough to keep the awkward slots staffed, and set the per-head threshold to reward genuine growth. When you can see fill rates and cost per head per class side by side, these decisions stop being guesses. This is the kind of visibility studio intelligence software like kaizenwell is built to surface, so you are adjusting pay against real attendance rather than instinct.
What to do with this
Start by building the true loaded cost of one class. Take the pay, add payroll tax and benefits, add a fair allocation for meetings and admin, add your average sub-coverage cost, then divide by realistic attendance rather than capacity. Do this for your best class and your worst.
- Compare cost per head, not rate. A cheap-looking flat rate on a half-empty class can cost more per member than a richer hybrid on a full one.
- Match the model to the slot. Use base-weighted pay to protect off-peak classes and per-head weighting to reward growth on classes that can genuinely grow.
- Price sub coverage before you need it. Decide the premium and the arrangement now, not at 9pm the night before.
- Pay for the off-class work you already depend on. If instructors do prep, meetings, and client contact, name it and pay it. It is cheaper than a wage claim.
The rate on the schedule was never the real number. Once you can see the loaded cost per head against the fill rate, the pay model stops being a line item you inherited and becomes a lever you actually control.
