The no-show cost model: pricing a missed appointment honestly

First, define a no-show

Before any math, agree on terms, because practices count no-shows differently. In this model, a no-show is a booked patient who did not arrive and did not cancel. A late cancellation is a cancellation inside the window your policy sets, often 24 hours. A walkout is a patient who checked in and left before being seen.

All three leave an empty slot, but they differ in one way that matters for cost: how much warning you had. A cancellation at 8 AM for a 3 PM visit can sometimes be refilled. A no-show at 3 PM almost never can. Keep them in separate columns so you can see each clearly. The model below covers true no-shows.

Layer 1: the lost slot

The slot cost is the collected value of the visit minus the variable costs you avoided by not seeing the patient. Most practice costs (rent, salaries, equipment, software) are fixed for the day whether the patient shows up or not. Only a small slice, such as single-use supplies, actually goes away.

Illustrative example: average collected value per visit is $175. Variable supplies per visit are about $12. The lost slot is worth $175 minus $12 = $163.

Now scale it. Say the practice books 1,200 visits a month and its no-show rate is 6%. These numbers are illustrative, not industry benchmarks. That is 72 no-shows a month. 72 x $163 = $11,736 a month in lost slot value.

Layer 2: staff time

Each no-show creates work. Someone notices the empty room, calls or texts the patient, notes the chart, tries to rebook and maybe rearranges the provider's afternoon.

Illustrative example: 10 minutes of front-desk time per no-show at a loaded cost of $22 an hour is about $3.67 each. 72 x $3.67 = about $264 a month.

This layer is small in dollars, but it matters in a different way: those 12 hours a month are hours the front desk was not answering phones or checking in arriving patients, which can create other leaks.

Layer 3: patients who never come back

Some patients who no-show rebook within a week. Others drift away. The ones who drift away take their future visits with them, and this is often the largest cost over a year.

To measure it, check how many of last quarter's no-shows have a completed visit within 30 days. Illustrative example: 55% rebook and are seen within 30 days, so 45% do not. Of 72 monthly no-shows, that is about 32 patients who drift.

If each of those patients would otherwise have had an illustrative 2 more visits over the next year at $175, that is 32 x 2 x $175 = $11,200 in future revenue at risk from each month's no-shows.

Keep this layer separate. It is not money lost this month, and some of those patients would have left anyway. But it shows why rebooking quickly matters as much as preventing the no-show in the first place.

Putting the model together

For this illustrative practice, the monthly no-show cost looks like this:

• Lost slots: $11,736 this month.
• Staff time: $264 this month.
• Current-month total: about $12,000.
• Future revenue at risk from patients who drift: $11,200 over the following year, reported on its own line.

1. Sensitivity check. One percentage point of no-show rate on 1,200 booked visits is 12 visits. 12 x $163 = $1,956 a month in slot value, or about $23,500 a year, before counting attrition.
2. Same-day fill check. If the practice manages to fill a quarter of no-show slots with same-day patients or a short-notice list, the slot layer drops by a quarter, from $11,736 to about $8,802.
3. Rebooking check. If the 30-day rebook rate rises from 55% to 75%, the drifting patients fall from about 32 to about 18, cutting the future revenue at risk by more than 40%.

Two levers, two different fixes

The model shows that no-show cost has two separate levers. Prevention and same-day fill shrink the slot layer: confirmations patients can answer quickly, an easy way to cancel instead of skipping, and a fast way to offer the open time to someone else. Rapid rebooking shrinks the attrition layer: reaching the patient the same day with a few concrete times, rather than a generic please-call-us message.

A simple rebooking text a front desk might send, kept to the minimum necessary: "[Practice name]: we missed you today. Reply 1 for Thu 10:20 AM, 2 for Fri 2:40 PM, 3 for other times. Reply STOP to opt out." No patient name, no visit reason, numbered choices.

Measure both levers monthly. The no-show rate tells you about prevention. The 30-day rebook rate tells you about recovery. Most practices only track the first.
