Byzzie No-show calculator
No-show cost calculator
Every no-show is a slot you held open and work you didn't get paid for. Put in your own numbers to see what no-shows cost your business in a year, and how much of it deposits could cover.
How the math works
Yearly no-show cost = appointments per week × no-show rate × average service price × weeks open.
With the example numbers above: 60 appointments × 8% = 4.8 no-shows a week. At $40 each over 48 weeks, that's $9,216 a year. A $10 deposit kept on each of those 230 no-shows would recover $2,304.
The real cost is usually higher. This doesn't count tips, a product sale you missed, or the client on your waitlist who would have taken the slot.
How to find your no-show rate
Look back over the last four weeks. Count appointments where the client didn't show and didn't cancel, then divide by the total number of booked appointments. Businesses that already take deposits will usually see a lower number than shops that don't, so measure your own instead of borrowing someone else's.
Ways small businesses cut no-shows
- Text reminders the day before and a few hours before, with a one-tap way to cancel or reschedule.
- Deposits for new clients, busy time slots, long services or clients who've no-showed before.
- A clear cancellation policy shown when the client books, not after they miss.
- A waitlist that's texted the moment a slot opens, so a late cancel still gets filled.
Byzzie is being built to do all four automatically, and its AI receptionist answers the calls and DMs that turn into bookings in the first place.
Common questions
How much do no-shows cost a small business?
Multiply your weekly appointments by your no-show rate, your average service price and the weeks you're open. A business with 60 appointments a week, an 8% no-show rate and $40 appointments loses about $9,216 a year over 48 weeks, before tips.
Should I charge a no-show fee?
Many do, either as a deposit at booking or a fee charged to a saved card. Deposits are easier to enforce because the money is collected up front. Whatever you choose, show the policy when the client books.
How big should a booking deposit be?
There's no single rule. Common choices are a flat amount like $10 to $20, or a percentage of the service. A deposit that covers part of the service usually discourages no-shows without scaring off new clients.
Is this calculator free?
Yes. It runs in your browser, needs no sign-up and doesn't save the numbers you type.
