No-show cost calculator
Estimate the monthly and annual revenue blocked by missed appointments and late cancellations.
What this result means
Compare no-shows and late cancellations separately.
Use a service-specific calculation when appointment values and durations vary widely.
This is blocked revenue, not final lost profit; some variable costs are not incurred when service is missed.
Monthly blocked value = weekly appointments × no-show rate × average booked value × 4.33, reduced by the estimated share refilled.Formula version static-v1
Use the result as a scenario, not a promise
Change one assumption at a time, compare the result with actual records, and save the definition used. The calculator does not know the business’s taxes, contracts, local rules, demand, or data quality.
