Class Price and Minimum Optimizer: What to Charge Per Seat

What should I charge per seat when a class only runs if enough people sign up?

Enter the price and average sign-ups from your past terms, plus seats, minimum to run and what a class costs you. The tool fits how sign-ups responded to price, sums the exact chance of every enrolment, and shows the price with the highest expected profit per class offered, the chance the class runs, and what it gains over your current price.

Arithmetic on figures you type. Not business, accounting or financial advice. The example figures are placeholders, not any school's prices, costs or sign-ups.

Your class

Seats per class

Room or teacher limit. Extra sign-ups go on a wait-list.

Minimum sign-ups to run the class

Below this you cancel. Zero means you always run.

Cost of running one class ($)

Instructor pay, room and anything paid whether 3 or 12 students show.

Extra cost per student ($)

Materials, books or payment fees for each enrolled student.

Your current price per student ($)

Optional. Shows what the best price gains over it.

Price elasticity, if you know it

Leave at 0 to fit it from the past terms below. 1.5 means a 10% price rise loses about 15% of sign-ups.

Classes you offer per month

Used only to turn a per-class gain into a monthly one.

Past terms

Price and average sign-ups, one pair per term

Write price:signups separated by spaces, like 140:10 170:7.5. Put + after a term that filled the room and had a wait-list, like 110:13+, because real demand was higher.

Needs at least two different prices that did not fill the room, or an elasticity you enter above.

Questions owners ask

What price should I charge for a class that only runs if enough people sign up?

Charge the price where the expected profit per class offered is highest. Raising the price lowers sign-ups, which raises the chance the class is cancelled for missing the minimum. The tool fits how sign-ups responded to the prices you tried, then sums the exact chance of every enrolment from zero to capacity and picks the best price.

How does the tool turn past terms into a demand curve?

Enter the price and average sign-ups from each past term. It fits a constant-elasticity curve to those points by least squares on their logarithms. A term that filled the room is marked with a plus and left out of the fit, because the true demand was higher than the seats.

What does the minimum to run change?

A class below the minimum is cancelled, so you earn nothing but also pay no fixed cost. Raising the minimum protects you from running at a loss but cancels more classes. The result shows the chance the class runs at the best price.

Can I trust the fitted elasticity?

Only as far as the data allows. Two prices fit any line exactly, and sign-ups also move with season, teacher and marketing. The tool warns on two-point fits and scattered data, and flags a best price outside the range you have tried.

Is this business or financial advice?

No. It is arithmetic on figures you type. Check refund, cancellation and consumer rules where you operate with a qualified advisor.

Not decided

Season and weekday effects, teacher reputation, marketing spend, repeat students who enrol again regardless of price, bundle and sibling discounts, refund and cancellation rules, and whether a lower price today trains customers to wait for discounts. Sign-ups are treated as independent draws whose average depends only on price.
