How the break-even calculator works

A class breaks even when the money it brings in covers the money it costs to run once. The calculator adds up everything you pay for one session, divides by what one attendee pays, and rounds up. That is the number of people who need to be in the room before you make anything at all.

Everything after that number is margin, which is why the three profit figures matter more than the break-even itself. A class that needs 7 of 12 spots is comfortable. A class that needs 11 of 12 is a coin flip every week.

What to put in each field

Coach or instructor pay. What you actually pay for the session, including prep time if you pay for it. If a salaried coach runs it, use the hourly equivalent so the class carries its real cost.

Space, equipment, cleaning. Anything that scales per session: room hire if you rent, a share of your lease if you own, consumables, laundry, the cleaner’s hour after a sweaty class. A quick way to get a per-session figure for a room you own is monthly occupancy cost divided by the number of sessions the room hosts in a month.

Marketing or platform fees. Booking platform fees per booking, the boosted post you ran for this class, a printed flyer. Leave it at zero if the class rides on your general marketing.

Price per attendee. For drop-in classes, the drop-in price. For members on unlimited plans, decide what one visit is worth to you: many owners take the average monthly fee and divide by the average visits per month. Whatever you pick, use the same rule across classes so the comparisons hold.

Capacity. The number of people who can safely take part. Not the fire code number, the number that still gives a good experience.

Fixed monthly cost. Optional. If this class exists to justify a new hire’s retainer, a software seat or a lease on a second room, put that monthly figure here and the calculator shows how many sold-out sessions it takes to cover it.

Reading the results

Break-even attendance is the floor. Compare it with your realistic average, not your best week.
Profit at 50%, 75% and sold out shows how forgiving the class is. If 50% is still negative, the class needs a strong launch or a different price to survive its first month.
Margin per spot when full is a good way to compare two very different classes. A cheap, high-capacity class and an expensive small-group session can look similar here even when every other number differs.

Pricing a specialty class

Specialty formats such as a lifting clinic, a technique workshop or a race-prep block usually cost more to run: a senior coach, longer sessions, smaller groups. Three approaches keep them profitable:

Price the series, not the session. A 6-week block paid up front locks in attendance, so break-even is calculated once rather than fought for weekly.
Cap the group and charge for the cap. A 6-person clinic at three times the drop-in rate often out-earns a 15-person class at the standard rate, and coaches prefer it.
Run it as a member benefit with a paid non-member price. Members fill the room and non-members carry the margin.

When running at a loss is fine

Not every class has to pay for itself. A free beginner session that converts to memberships, a kids’ class that brings parents into an adult programme, a community night that keeps people renewing: these are marketing, and the calculator tells you exactly how much that marketing costs per session so you can decide with open eyes.

The number the calculator cannot give you

Break-even tells you how many people you need. It cannot tell you how many will come. That is a demand question, and the cheapest way to answer it is to ask before you schedule: post the idea, let members vote with an email, and launch when the votes clear your break-even line.
