How to calculate your no-show rate.
Formula, free calculator, three worked examples, and the benchmark you should be comparing against in your industry.
rate = (no-shows
÷ scheduled)
× 100Two-input rate entry
Scheduled and no-shows for any period (day, week, month).
Total bookings for the period
Did not appear and did not call ahead
23 no-shows out of 100 scheduled appointments.
Three terms, four edge cases
no-show rate = (no-shows ÷ scheduled) × 100Patients who did not appear and did not contact you before the appointment. No advance notice, no call, no cancellation.
Total appointments booked for the period, including those who showed up. Walk-in demand is excluded.
Do NOT include same-day cancellations as no-shows. Do NOT count rescheduled appointments. Do NOT include late arrivals who still received service.
Three real-world entries
Typical primary care practice. At this rate you are near the national average of 19% (MGMA 2024). Acceptable but reducible.

How to track no-shows over time
Calculate once per month. Plot the rate on a simple chart. Compare month over month. Look for a downward trend after implementing reminder systems.
No-show rates typically spike 20 to 30% in summer (July to August) and around major holidays. Adjust your targets seasonally rather than comparing December to August directly.
Track by provider, by appointment type, and by patient demographic if your EHR supports it. New patients have 2 to 3x higher no-show rates than established patients in most practices.
