Booking performance gets easier to discuss when missed appointments are turned into one clear rate instead of a raw count. This calculator helps visitors estimate no-show rate and attended appointments from scheduled and missed appointment totals.

Run the estimate

No-show rate calculator

Estimate the percentage of scheduled appointments that ended as no-shows.

7.50%

Estimated no-show rate based on no-show appointments divided by the total scheduled appointments entered.

No-show rate7.50%
Attended appointments222
No-show appointments18
Scheduled appointments240
  • 18 no-shows out of 240 scheduled appointments gives a no-show rate near 7.50%.
  • 222 appointments remain attended in this simple comparison.
  • Use the result as a quick operations check only, because cancellation rules and same-day reschedules can change how a business defines a no-show.

This is a simple booking-performance metric. Actual operations review can vary with cancellation rules, late reschedules, walk-ins, and how attended appointments are counted.

What the calculator is doing

Enter the total scheduled appointments and the number of no-show appointments.

The calculator divides no-shows by the total scheduled appointments to estimate the rate.

It also shows how many appointments remained attended in the same period.

This is a practical booking metric, not a full operations analysis. Cancellation rules, late reschedules, and how attendance is defined can change the true business picture.

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Track missed bookings more clearly

Turning no-shows into a percentage can make recurring scheduling issues easier to spot.

Compare two periods or locations

A rate is usually easier to compare than raw no-show counts when volumes differ.

Use it with service-team metrics

No-show rate can become more useful when paired with response, occupancy, or scheduling tools.

Common questions

How is no-show rate calculated here?

The calculator divides no-show appointments by total scheduled appointments to estimate the missed-appointment percentage.

Why show attended appointments too?

Seeing the attended count alongside the no-show rate can make the result easier to explain operationally.

Why might a business define no-show differently?

Some businesses separate cancellations, same-day reschedules, and late arrivals differently, which can change the final metric.
