No-show and deposit calculator for booked sessions
Work out what empty booked slots cost your venue each month, and how much of that a deposit and a walk in refill genuinely recover.
A no-show at an action venue is not a missed sale, it is a destroyed slot. The room was blocked, the coach was scheduled, the lane was held, and the hour is gone whether anyone throws or not. That is different from a restaurant table, which can turn twice more before close.
This calculator puts a number on that. Enter how many sessions you sell in a normal week, what a guest pays, how often parties fail to arrive, and what you already recover through deposits and same day walk ins. The result is the exposure that survives your current policy, expressed per month and per year.

What is still gone after deposits and refills, across twelve months.
Treat the annual figure as the budget you are handing to no-shows before you change a single policy.
Why a dead slot costs more than the ticket
The ticket price is only the visible part. A room booked for 7:15 also holds a game master on shift, a reset window that nobody else can use, and a slot that a waiting group would have taken if the calendar had shown it open. At an axe hall the coach is rostered for the block whether four people throw or none.
Raising the no-show rate in this model by a couple of points is instructive. Small changes move the annual figure more than owners expect, which is why deposit policy tends to pay for itself faster than a price increase does. The same is true of releasing an abandoned slot back to the calendar quickly rather than at close of business.
Turning the number into a policy
Once you know the annual exposure, the policy question gets easier. A modest deposit on every booking, a larger one on groups over eight, and a clear cancellation window handle most of it without punishing regulars. Corporate bookings and birthday parties are usually where the biggest single losses sit, because they hold the most seats.
The second lever is speed. If a party has not signed and has not answered a reminder by an hour before the slot, you want that slot back on sale rather than sitting blocked. Booking and release in one flow makes that signal visible early, because unsigned participants show up as a gap long before the group is due at the door.
Questions about this calculator
What no-show rate should a venue expect?
It varies by market, price point and how you sell. Venues with no deposit and heavy online booking tend to see more abandonment than venues that take a card at booking. Track your own for a month rather than trusting a benchmark from another trade.
Should the refill share include partial parties?
No. Keep this field for slots that were fully abandoned and then resold to somebody else. Parties who arrive with fewer people than they booked are a separate leak, and mixing them in makes the recovery figure look better than it is.
Does a deposit hurt bookings?
Most operators who add a modest deposit see a small dip in bookings and a larger drop in abandoned slots, which nets out positive. Test it on weekend evening slots first, since that is where a dead room costs the most.

Now do something with that figure
The number this calculator just produced is what your current setup carries into next month. In a short demo we will run your own inputs live and show the flow that shrinks it: every named participant signing under the slot they booked, a guardian tied to each minor, and a scan that clears a party of ten before the coach starts the briefing.
