No-Show CostCalculator
Enter your weekly sessions, no-show rate, and fee. See what missed sessions cost per month and per year, and what any reduction would be worth.
By Jesse, Registered Psychotherapist.
Sessions on the calendar in a typical week, kept or not.
The share of booked sessions that produce no revenue: missed appointments plus cancellations you do not charge for. Count it from your last two or three months, not from memory.
What a kept session actually collects. If part of your caseload is insurance, use a blended average.
Check this if a late-cancellation or no-show fee policy exists in your practice.

What a Reduction Would Be Worth
These are arithmetic scenarios, not promises about what reminders or any product will do. No vendor number substitutes for measuring your own rate before and after a change.
Every number comes from your inputs; the page carries no benchmark no-show rates or vendor effectiveness claims. To see how no-shows change the caseload you need, use the caseload break-even calculator.
What the no-show math actually shows
No-shows are a rate, not bad luck
One missed session feels like an off day. The same miss repeating at a steady percentage of the calendar is a rate, and a rate multiplied by your fee and 52 weeks is a number worth knowing before deciding whether it is worth fixing.
A fee policy only counts when it collects
The listed fee matters less than the share of missed sessions where it is actually charged and paid. A $100 fee collected half the time offsets exactly as much as a $50 fee collected every time.
Reminders are arithmetic, not magic
Whatever a reminder system does to your rate, the value of the change is the fraction of the annual loss it removes. Measure your baseline first, change one thing, and re-measure. The scenarios above price the outcomes without promising them.
A fuller pipeline makes a no-show cheaper to absorb
The same missed slot hurts more in a practice with three inquiries a month than in one with fifteen, because an empty hour with a waitlist behind it gets refilled. Reducing the rate and filling the pipeline are separate levers, and both show up in this number.
Common Questions
What counts as a no-show?
For this math, anything booked that produced no session revenue: missed appointments, same-day cancellations you did not charge for, and late cancellations outside your policy window. If a slot was held for a client and no money arrived, it belongs in the rate.
How do I find my actual no-show rate?
Pull the last two or three months from your calendar or EHR and divide sessions that produced no revenue by sessions booked. Most therapists guess low, because a scattered one-a-week pattern never feels like a rate. Use the counted number, not the felt one.
Do reminder systems really reduce no-shows?
This page does not quote vendor numbers, because the honest answer is that the effect varies by practice. What the calculator can tell you is what any given reduction is worth in your numbers: cut your rate by a quarter and you keep a quarter of the annual loss. Measure your own baseline, turn reminders on, and re-measure a month later.
Should I charge a late-cancellation fee?
That is a policy decision with clinical and relational tradeoffs, not just a financial one, and the right answer differs by caseload and setting. What the math shows is that a fee only changes the loss to the extent it is actually collected, which is why the calculator asks for the collected share, not just the policy.
