How to use the appointment no-show cost calculator
- Enter how many appointments you book per week and how many weeks a year you operate.
- Enter your no-show rate from your booking records and the average value of an appointment.
- Enter the staff cost for one appointment slot.
- Enter the share of no-shows you believe reminders, deposits or rebooking could recover, and any monthly cost for that system.
- Review lost revenue, idle staff cost and net recovery, then copy the summary.
Worked example
100 appointments a week, 50 weeks, 10% no-shows, $120 value
5,000 appointments a year × 10% = 500 no-shows. 500 × $120 = $60,000 revenue lost per year. At $25 staff cost per slot, $12,500 of paid staff time earns nothing. If reminders recovered 30% of no-shows, that is 150 appointments or $18,000 a year; with a $100 per month reminder tool the net recovery is $16,800. The 30% recovery rate is an example assumption.
How it works
Appointments per year = per week × working weeks. No-shows = appointments × no-show rate. Lost revenue = no-shows × average value. Idle staff cost = no-shows × staff cost per slot (shown separately, not added to lost revenue). Recovered revenue = no-shows × recoverable % × average value. Net recovery = recovered revenue − reminder system cost × 12.
Assumptions
- No-show rate, appointment value and staff cost per slot are your own figures.
- The share of no-shows that could be recovered is your own assumption; no recovery rate is implied.
- Reminder or rebooking system cost is whatever you enter from your own quote.
- Staff cost for empty slots is informational and is not added to lost revenue, to avoid counting the same loss twice.
- Starting values in the tool are example values to replace with your own; they are not industry benchmarks.
Frequently asked questions
Why is staff cost not added to the total?
You pay staff for the booked time whether or not the client turns up. The real loss is the revenue that slot would have earned. Staff cost shows how much paid time was unproductive, which is useful context but would double count if added.
Should late cancellations count as no-shows?
If the slot could not be refilled, yes. Many businesses track "no-show or late cancel" together for this reason.
How can I reduce no-shows?
Common approaches are automated SMS or email reminders, deposits or card-on-file policies, easy online rescheduling and a waitlist to fill gaps. Test the recovery rate you actually achieve and update the calculator.
Limitations
- Assumes every no-show slot is lost; it does not model waitlists or walk-ins filling gaps.
- Uses a single average appointment value.
