About this calculator
A no-show doesn't just lose the revenue from that party — it often costs the restaurant a second booking too, since a held table that could have gone to another party during a fully booked period represents real opportunity cost, not just an empty seat. This calculator takes your no-show rate, average party size, average check, and bookings per period, and calculates total lost revenue from no-shows, then models the financial case for a deposit or credit-card-hold policy by estimating how much a typical policy reduces no-show rates (industry data suggests deposits cut no-shows by roughly 50-70% for restaurants that previously had no policy). Fine dining and prix-fixe restaurants with high average checks see the most dramatic dollar impact from no-shows and are also where deposit policies are best tolerated by guests, since the practice is now widely expected at that price point.

FAQ
How much do deposit or credit-card-hold policies actually reduce no-shows?
Industry data and operator reports commonly cite 50-70% reductions when moving from no policy to a card-on-file or prepaid deposit system, since the policy filters out casual double-bookers who reserve at multiple restaurants and no-show the ones they don't choose.
Will a deposit policy hurt bookings overall?
For mid-range casual dining, yes, some guests will book elsewhere rather than provide a card. For fine dining, tasting menus, and high-demand restaurants, guests largely expect it now and it rarely reduces total covers meaningfully — it mainly changes who shows up.
What's a reasonable no-show rate before I worry about it?
5-10% is common and generally tolerable for casual restaurants with walk-in traffic that can absorb the empty tables. Above 15%, especially for restaurants that turn away walk-ins to protect reservation holds, the lost-opportunity cost becomes significant enough to act on.
Are there alternatives to a hard deposit?
Automated text/email confirmation requests 24-48 hours out, a clear cancellation window policy, and overbooking by a small buffer percentage (common in hotels, riskier in restaurants) are lower-friction alternatives that recover some of the loss without a hard deposit's booking friction.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
