Dental no-show cost calculator
Dental losses are best measured in chair time, not just a flat per-visit figure. This calculator models lost operatory production from your chairs, weekly open hours, and the share of missed appointments that are higher-value restorative rather than hygiene.
Dental inputs
Estimated lost chair production
Lost production per year
$399,360
Missed chair-hours × restorative-weighted production × 52.
Lost production per month
$33,280
Idle chair-hours per week
24.0
Billable operatory time left unproductive.
Break-even vs NoShowLine
0.5 chair-hrs / mo
Recovering about 0.5 productive chair-hours a month offsets a $149 subscription. Arithmetic, not a savings promise.

How this estimate is built
The math is transparent so you can sanity-check every figure against your own book.
- 01Weekly chair-hours = operatory chairs × open hours per week.
- 02Missed chair-hours = weekly chair-hours × no-show/late-cancel rate.
- 03Restorative-weighted production = production per chair-hour × (1 + restorative share × 0.8).
- 04Annual lost production = missed chair-hours × weighted production × 52.
Planning benchmark
Dental practices: typical no-show range
- No-show rate
- 10–20% (typical 15%)
- Cost per miss
- $250–450 per missed visit
At the typical 15% rate, a four-chair practice open 40 hours a week can leave a meaningful share of billable operatory time unproductive across a year. These are planning estimates; replace them with your own measured data before making any financial decision.

Dental calculator FAQ
Why measure dental no-shows in chair-hours?
A missed 90-minute restorative block costs far more than a missed hygiene check. Chair-hour production captures the time and clinical value tied to the slot rather than a single flat figure.
What production figure should I use?
Use your practice's own average billed production for one productive chair-hour. If you do not track it, divide a normal week's production by productive chair-hours.
Is the estimate recoverable revenue?
No. It estimates production attached to lost chair time. Actual recovery depends on advance notice, refilled slots, capacity, payer terms, and your confirmation workflow.
