About No Show Cost Calculator

No-show cost is the revenue from missed appointments that could not be refilled. A waiting list or standby system is the single most effective mitigation, because it converts a total loss into a partial one without penalising clients.

Formulas

No-show rate

Rate % = No-shows and late cancellations / Appointments scheduled x 100

Net loss

Net loss = No-shows x Average revenue x (1 - Refilled share %)

Worked example

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Do deposits reduce no-shows?

Substantially, typically by half or more, but they also deter some bookings. Reminder sequences achieve much of the benefit without that cost.

What no-show rate is normal?

5-10% for most appointment-based services, higher for free consultations and lower where a deposit or card is held.
