No-show cost calculator for clinics and service businesses

Missed appointments feel like a scheduling annoyance until you multiply them by a year. Enter your weekly appointments, no-show rate and average revenue per visit to see what no-shows and late cancellations actually cost, and what a signed cancellation policy plus reminders would recover.

What you can realistically recover

How to use it

  1. 1

    Enter your weekly volume and no-show rate

    Count no-shows and late cancellations together; both leave a slot empty. If you do not track the rate, pull two weeks of the schedule and count. Most dental, physio, med spa and home-service schedules run 8–20% before they fix it.

  2. 2

    Add average revenue per appointment

    Use the average collected per visit, not your highest service. For trades, use the average ticket for a scheduled call.

  3. 3

    Estimate refills and your target rate

    A short-notice waitlist refills some cancelled slots; 20–40% is typical once you keep one. A cancellation policy the client signs at intake, plus reminders at 48 and 24 hours with a one-tap reschedule, commonly brings the rate down to 3–6%.

  4. 4

    Read the yearly cost and the recovery

    The panel shows missed appointments per year, revenue lost after refills, and the difference between today's rate and your target. That difference is the budget you have for reminder software and front-desk time.

No-Show Cost Calculator FAQ

What no-show rate is normal?

Unmanaged schedules commonly run 10–20% for clinics and 8–15% for scheduled home-service calls. Practices with a signed policy, a reminder sequence and a waitlist typically hold 3–6%.

Should I charge a no-show fee?

A fee works when it is agreed in writing at intake, stated in one sentence, and enforced consistently. The fee's job is to make people call to reschedule, not to generate revenue; most well-run practices waive it the first time and enforce it the second.

How far in advance should reminders go out?

Two touches: 48 hours (long enough to refill the slot) and 24 hours (short enough to be remembered), each with an easy reschedule link or reply. A third reminder the morning of the appointment helps for procedures with prep.
