What do empty class spots cost your studio?

There's no single number that fits every studio, which is why this calculator asks you to set your own current and target rates instead of assuming one. Busy peak classes can run near full while off-peak slots sit half empty, so your average across the week is what matters. Once you know your real average, a realistic target is a modest lift on it rather than 100%. The gap between where you are and where you could be is the revenue this calculator shows you.

When a class fills up, new sign-ups join a waitlist instead of being turned away. The moment someone cancels or a spot opens, the system offers it to the next person on the list and confirms them, usually by an instant message with a booking link. No one at the front desk has to notice the cancellation, call around, or manually re-fill the spot. Seats that used to go empty after a late cancellation get sold again on their own.

Yes. We don't replace the booking app you already use. We connect to it and add the layer it's missing: a waitlist that auto-promotes, one-tap booking links, and reminders that cut no-shows. Your members keep booking the way they already do, and the empty-seat recovery runs on top of your existing setup.

Set your own numbers in the calculator and compare the annual figure to the cost of a system. The recovered seats are money you're already losing every week, so the system pays for itself out of revenue that was leaking anyway. Most studios work with an implementation partner who builds the booking and waitlist layer once and maintains it on a monthly subscription.
