Your Saturday 9 a.m. instructor taught 26 people last week. Your Tuesday 6 a.m. instructor taught four. You paid them both $50.

Nobody has said anything yet. But your Saturday coach has done that math, and so has the studio across town that's been trying to hire them. Meanwhile, your Tuesday coach has no financial reason to fix the emptiest class on your schedule.

Instructor pay is usually the biggest cost a studio owner can actually control; in many boutique studios it runs somewhere between 20% and 35% of revenue. Yet most owners set it once, in a hurry before opening, and never revisit it. Here's how to build a structure that rewards full rooms, protects your margins, and doesn't start a war in the staff group chat.

The Three Ways Studios Pay (And Where Each Breaks)

Almost every studio pays instructors one of three ways.

Flat rate per class. Typically $35–$75 a class, depending on your market and the instructor's experience. It's simple and predictable, which is why it's the default. The problem: it pays the same for 4 people as for 26. You overpay for empty classes and underpay the coaches who fill your best slots.

Pure per-head. Usually $3–$6 for every client who checks in. It rewards growth, but it punishes anyone teaching a new class, an early slot, or the slow weeks of August. An instructor building a 6 a.m. class from scratch might earn $15 for showing up at 5:40. They won't stay long enough for the class to grow.

Hybrid: a base plus a per-head bonus. A guaranteed base for showing up and teaching well, plus a bonus for every client above a set number. This is where most studios that keep great coaches for years end up, and it's what the rest of this post is about.

Build the Hybrid With Three Numbers

The formula is simple:

Pay per class = base + (clients above threshold × bonus per head)

You need to set three numbers.

1. The base. What a solid instructor could earn teaching a comparable class elsewhere in your area. Ask your own team; most teach at two or three studios and will tell you. If your base is below market, no bonus will save your hiring.

2. The threshold. Set it at the class's break-even headcount: the number of clients it takes to cover the base, rent for that hour, and your other per-class costs. Below the threshold, the class is losing money. Above it, you're sharing upside you've actually earned. For most boutique studios, this lands around 40–60% of room capacity.

3. The bonus per head. $2–$5 is the typical range. Go higher in premium markets or small rooms (a 12-reformer Pilates studio), lower in big ones (a 40-person HIIT floor).

Here's how it plays out with a $45 base, a threshold of 10, and $4 per head:

Check the Math Against Your Revenue

Model the new structure against last quarter's real headcounts before you announce anything
Model the new structure against last quarter's real headcounts before you announce anything

Before you commit, sanity-check the structure against what each class actually brings in.

Start with revenue per visit. If your unlimited membership is $179 and members average 9 visits a month, that's about $20 a visit. Blend in class packs and drop-ins, and many studios land between $18 and $28.

Now run the example above at $20 a visit:

That's the shape you want. The percentage drops or holds as classes fill, so your best classes stay your most profitable ones even after the bonus. If full classes are paying out more than about 30% of their revenue, your bonus is too rich or your threshold is too low.

Then model it against your last three months of real data. For every class, you need the checked-in headcount (not bookings; no-shows don't count) and what you paid. If your bookings and check-ins run through one platform, like Kinetic, that history is already there by class and by instructor, not scattered across sign-in sheets and a payroll spreadsheet.

You're looking for two answers: what happens to total payroll, and which instructors would earn more or less.

A Worked Example: The Cycling Studio

Take a 28-bike cycling studio paying nine instructors a flat $50 a class. The average ride has 14 people. Saturday mornings and weeknight 6 p.m. rides regularly hit 25. The 6 a.m. rides hover around 7.

The owner keeps the $50 base so nobody's paycheck goes down, sets the threshold at 14 riders (the studio's break-even), and adds $3 for every rider above it:

Your fullest rides should be your best-paid ones, and still your most profitable
Your fullest rides should be your best-paid ones, and still your most profitable

The studio's cost on that Saturday ride goes up $33, on a class bringing in roughly $500. The instructors carrying the prime-time schedule pick up a few hundred dollars a month. Payroll only rises on classes that were already the most profitable on the schedule.

And the 6 a.m. coach stuck at 7 riders? For the first time, filling that room is worth something to them. That's the behavior change you're paying for.

Flat pay tells your best coach that a full room and an empty one are worth the same to you.

Write Down the Edge Cases Before They Become Fights

Pay structures rarely blow up over the formula. They blow up over the exceptions nobody decided in advance. Settle these in writing:

One more: whether your instructors are employees or contractors affects what you can require of them and how you handle prep time. That's a question for your accountant, not a blog post.

How to Announce It (Script Included)

Never roll out a pay change in a group text or a staff meeting. Do it one-on-one, with each instructor's own numbers in front of them. Something like:

"I'm changing how we pay for classes, and I wanted you to see your numbers before anyone else does. Your base stays at $50, so nobody earns less for teaching the same class. What's new: every rider over 14 adds $3. If this had been in place last quarter, you'd have earned $1,140 more. I'd rather pay you well for full rooms than pay everyone the same and hope."

Expect two questions:

A pay structure your coaches understand is one they'll build classes around
A pay structure your coaches understand is one they'll build classes around

After launch, send each instructor a simple monthly statement: every class, its headcount, and what it paid. Transparency kills most suspicion before it starts. And rerun your revenue check every six months, or any time you change membership prices.

The Recap

Pay the people who fill your rooms like they fill your rooms. They notice, and so does every studio trying to hire them.
