What should I actually pay a substitute teacher when a class only has four students?

Pay the sub the rate you would pay the regular teacher for that slot. Then fix the slot, or close it. Discounting a sub because four people showed up punishes the one person who solved your problem, and it teaches your roster that covering a quiet class is a bad deal. The next time you need someone at 6am on a Tuesday in February, nobody offers.

That is the short answer. The longer answer is that four students in a room is not a sub problem, it is a schedule problem wearing a sub costume. The useful work is figuring out what a seat in that room actually costs you, deciding at what attendance the slot stops earning its keep, and then choosing a pay structure that survives both the busy weeks and the empty ones.

The three pay structures studios actually use

Almost every studio lands on one of three shapes.

Flat rate. A fixed dollar amount per class, often tiered by slot or by seniority. Simple, predictable for both sides, and the easiest to explain to a roster. All attendance risk sits with the studio.

Per head. A dollar amount per student, sometimes with a floor. The teacher shares the risk and shares the upside. Common in donation based and community studios, and in rented room arrangements.

Hybrid. A base amount plus a per student amount above a threshold. Most large rosters end up here, because it protects the teacher on a snow day and pays her properly when she fills the room.

A fourth shape exists at the edges: revenue share, where the teacher takes a percentage of what the class collected. It is honest but it is miserable to administer once you have class packs, memberships and intro offers, because you have to decide what a membership visit is worth before you can split it.

Cost per class seat: fixed rent, staff and the marginal teacher

You cannot judge a rate without knowing the cost of the hour. Build it once. Every number below is an assumption you should replace with your own.

Assume a studio with $4,800 monthly rent including common charges, $900 in utilities, insurance and software, and $1,500 in front desk coverage. That is $7,200 of fixed monthly cost. Assume the schedule runs 60 classes a week, roughly 260 classes a month.

• Fixed cost per class on the schedule: $7,200 / 260 = $27.69
• Teacher pay for the class, assume flat: $45.00
• Fully loaded cost of running that class: $72.69

Now the revenue side. If your average revenue per visit is $14 after you blend drop ins, ten packs and unlimited memberships across all visits in a month, then:

• Break even attendance: $72.69 / $14 = 5.2 students
• Break even on the teacher pay alone, ignoring fixed cost: $45 / $14 = 3.2 students

Two thresholds, and they matter differently. Below 3.2 students the class does not even cover the person teaching it. Between 3.2 and 5.2 it contributes something toward rent you are paying anyway. Above 5.2 it earns.

Calculate your own average revenue per visit properly. Take total membership and pack revenue for a month, add drop in revenue, divide by total visits recorded. Owners consistently guess high on this figure, often by four or five dollars, because they think in list prices rather than in what a nine visit month does to an unlimited membership.

Where a flat rate stops working on a 6am slot

Take the numbers above to a real slot. The Tuesday 6am has averaged 4 students for the last eight weeks.

• Revenue: 4 x $14 = $56
• Teacher: $45
• Contribution toward fixed cost: $11

Eleven dollars an hour toward a rent bill you owe regardless. The class is not losing money in cash terms, which is why so many of them survive for years. It is losing on every other axis: it burns a teacher's early morning, it occupies a room, and it is the class you have to find a sub for when she gets sick.

Here is a decision rule you can apply this week to every slot on your schedule. Use an eight week rolling average of attendance, so a single holiday week does not condemn a class.

Eight week average	Status	Action
Below teacher break even (here, 3.2)	Subsidized	Close it, merge it into an adjacent slot, or move it to a hybrid rate with the teacher's agreement
Between teacher and full break even (3.2 to 5.2)	Marginal	Give it one more eight week cycle with a named growth plan, then decide
Full break even to double (5.2 to 10.4)	Healthy	Leave it alone
Above double	Strong	Consider a second slot in the same style, or a larger room

Notice that none of the actions is "pay the sub less." A studio that quietly pays a sub $30 for a class the regular teacher gets $45 for is not saving money, it is spending goodwill at a terrible exchange rate.

Per head pay and why teachers resist it

Pure per head sounds fair. It rarely feels fair to teachers, for three reasons they will articulate the moment you propose it.

First, teachers do not control attendance. Your marketing does, your schedule does, the weather does, and the January to March curve does. Handing someone the variance without the levers reads as risk transfer, not as partnership.

Second, per head makes covering unfamiliar classes irrational. A sub walking into someone else's Thursday community class has no relationship with those students and no ability to fill the room in 48 hours. Under per head, the classes hardest to cover become the least attractive to cover.

Third, if your teachers are employees, per head is a piece rate and you still owe minimum wage for all hours worked and overtime past 40. A three student class at $7 per head is $21 for what may be 90 minutes with setup and check in. That is below the floor in every state. The structure does not remove the obligation, it just hides it until someone files a claim.

Hybrid base plus head count, and how to set the base

The hybrid fixes most of this. Structure: a base that covers the teacher's time at a defensible hourly figure, plus a per student amount that starts at your break even attendance.

Using the same studio: set the base at $32, and add $4 per student from the sixth onward.

Students	Base	Per head	Teacher total	Class revenue at $14
4	$32	$0	$32	$56
8	$32	$12	$44	$112
14	$32	$36	$68	$196
22	$32	$68	$100	$308

Set the base by working backward from time, not from tradition. If the teacher is committed for 90 minutes door to door and you want her clearing $21 an hour, the base is $32. That figure is your floor and it should also clear minimum wage across the full committed window in your state.

Set the per head threshold at your full break even, not at zero. Above that point every additional student is genuinely incremental margin, and sharing it is cheap for you and motivating for her.

One warning. If the difference between a quiet class and a full one is $70 to the teacher, she will notice which slots you assign her. Rotate the good slots or you will build resentment faster than you build revenue.

Whether subs should earn the same rate as the regular teacher

Same rate for the same slot, with two narrow exceptions.

The first is a genuine seniority tier that applies to everyone. If your rate card pays a lead teacher $55 and a newer teacher $45, and a newer teacher covers a lead teacher's class, she is paid $45. That is a rate card, not a sub penalty, and teachers accept it because it is visible and applies to them when the roles reverse.

The second is a short notice premium, in the sub's favor. A flat $10 or $15 on top for anything claimed inside 24 hours. It costs you a handful of dollars a month and it dramatically shortens the time a request sits unclaimed.

Never pay a sub less because the class is small. She had no say in the schedule, no say in the marketing and, usually, no relationship with those four students.

Building a rate card you can defend to your whole roster

Write it down and publish it to the roster. One page.

1. Structure. Name it: flat, per head, or hybrid with the base and threshold spelled out.
2. Tiers. Two or three, with the criteria for moving up stated in terms anyone can verify, such as classes taught at your studio or a specific credential.
3. Slot differentials. If 6am pays more than 6pm, say so and say why.
4. Sub rules. Subs earn the covering teacher's own tier rate for that slot. Short notice premium stated with its cutoff.
5. Non class time. What is paid: meetings, mandatory trainings, cover shifts at the desk.
6. Review date. One date a year when rates are reviewed, so you are not negotiating one on one in the hallway all year.

The card only works if the numbers behind it are real. That means knowing, per slot, who actually taught and how many students were actually on the mat, over enough weeks to average.

MatCount keeps that record without anyone chasing it: availability from the roster, sub requests claimed with one tap, and a pay run built from the classes that were genuinely taught. Run your rate card against eight weeks of real numbers and the difficult slots identify themselves.
