What are no-shows costing your schedule?
Start with one of ten profession benchmarks, then replace the prefilled rate and value with your own data. The result is scheduled revenue at risk—not a promise that every missed dollar can be recovered.
Your schedule inputs
Prefill: 10–20% (typical 15%) · $250–450. The calculator uses the typical rate and the midpoint of the supplied cost range; replace both with your own measured data.

At this appointment value, recovering 0.43 appointment per month equals a $149 NoShowLine subscription. This is arithmetic, not a savings promise; results depend on your baseline and workflow.
Protect these appointments with NoShowLineEstimate only. This is arithmetic on your inputs, not a savings promise or financial advice.
The formula is intentionally transparent.
Weekly appointments × 52 × no-show rate × average appointment value = annual scheduled revenue at risk. Divide by 12 for the monthly estimate.
- 01Use scheduled appointments, not total inquiries.
- 02Calculate your no-show rate from a consistent date range.
- 03Choose scheduled or collected value and use it consistently.
- 04Track advance releases and refilled slots separately from no-shows.

How to calculate your no-show rate
Formula
No-show rate = missed appointments ÷ scheduled appointments
Multiply by 100 to express it as a percentage. Use the same date range and the same definition of "missed" (no-shows only, or no-shows plus late cancellations) every time you calculate it, so later comparisons are consistent.
Worked example
A practice scheduled 100 appointments last month and 8 were missed without notice.
8 ÷ 100 = 0.08 → 8% no-show rate
Enter that rate, along with your appointment volume and average appointment value, into the calculator above to see what it costs in scheduled revenue.

Calculator FAQ
How do you calculate a no-show rate?
Divide missed appointments by scheduled appointments for the same date range, then multiply by 100. For example, 8 missed out of 100 scheduled is an 8% no-show rate. Keep the definition of "missed" (no-shows only, or no-shows plus late cancellations) consistent between periods so the rate stays comparable.
How is the cost of no-shows calculated?
Annual scheduled revenue at risk equals appointments per week × 52 × no-show percentage × average appointment value. Monthly impact is the annual estimate divided by 12.
Does the estimate equal recoverable revenue?
No. It estimates scheduled value attached to missed appointments. Actual recovery depends on advance notice, refill rate, payment collection, capacity, costs, and the confirmation workflow.
Where do the profession prefills come from?
The no-show field uses the typical point stated in the supplied profession benchmark. Appointment value uses the midpoint of its estimated cost-per-miss range. Replace both with your own data.
