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.

Waiver coverage gap and counter signing load
See how many participants still sign standing at your desk each month, how many of those are minors needing a guardian, and what that costs you in staffed hours.
Every venue in this trade knows the shape of the problem without having measured it. Guests arrive, half of them have signed, the rest crowd a tablet in the lobby, and a minor turns up with an older sibling instead of a parent. The session starts late, the reset window compresses, and the next group waits.
This calculator sizes that load. Enter your monthly participant count, the share who sign before arrival, the share who are under 18, and how long a counter signature really takes once you include finding the booking. You get the unsigned volume, the guardian volume, and the staffed hours the signing consumes, split out for your weekend peak.
Your result
Unsigned guests per month
1,320
Participants who still have to sign standing at your front desk.
Guardian signatures needed
720
Minors each month whose release needs a named parent or guardian.
Counter hours per month
88.0
Staffed hours spent collecting signatures instead of running sessions.
Of that, in the weekend rush
48.4
The share of the signing load landing between Friday and Sunday.
The weekend figure is the one to act on, because those hours fall on the shifts where you have the least room to absorb them.
Minors are where the gap gets expensive
A missing adult signature is an annoyance. A missing guardian signature is a refused entry or, worse, a child who plays on a release nobody with authority signed. Birthday parties are the sharp end of this, because the host parent often arrives with six children belonging to other households and no authority for any of them.
The guardian figure in this model tells you how many of those pairings your desk handles in a month. If the number is large, the fix is upstream: collect each minor name at booking, send the guardian a link tied to that child, and let the desk see a clean cleared count rather than a pile of forms with mismatched surnames.
Turning counter hours back into sessions
Counter hours are not abstract. On a Saturday they come directly out of resets, briefings, floor supervision and lane coaching. A trampoline court short one monitor because that person is running a tablet in the lobby is a supervision problem, not just a service one, and it appears in exactly the hour when the court is fullest.
Push the signed before arrival percentage up in the model and watch the weekend hours fall. That is the entire argument for taking the release inside the booking flow: not that signing is slow, but that signing at the counter happens at the worst possible moment for a venue with fixed session cadence.
Questions about this calculator
How do we measure our own signed before arrival share?
Take one busy week and count, per booking, how many participants had a release on file before the party reached the desk. Divide by total participants that week. Most venues guess high before they count and land lower than expected.
Should expired releases count as unsigned?
Yes, if your policy sets an expiry. A release signed fourteen months ago under an annual policy is a counter task the same as a first visit, and it should sit in the unsigned column so the number reflects real desk work.
Does four minutes per signature seem high?
It includes the whole interaction, not just typing: finding the booking, spelling a name, handing over a tablet, waiting, checking a guardian, then confirming. Time it yourself on a Saturday before deciding the default is wrong.

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.
