The Empty Chair Read
Every cancelled and no showed slot has a price. Most owners guess it far too low, because they price it on net margin when the rent, the lights and the staffed hour were already paid. Six figures below, and you have the real one.
Your figures
Rough is fine. This is a read, not an audit. The point is the size of the number, not its last dollar.
The reading
The same number, three ways
| Period | Slots left empty | Billing missed | Contribution lost |
|---|---|---|---|
| A week | 0 | $0 | $0 |
| A month | 0 | $0 | $0 |
| A year | 0 | $0 | $0 |
A month is a twelfth of the year rather than four weeks, so the three rows agree with each other.
What comes back if you refill more of them
| If you refilled | Extra slots sold a year | Contribution recovered | A fix pays for itself under |
|---|---|---|---|
| 1 in 4 of the empties | 0 | $0 | $0 a month |
| Half of the empties | 0 | $0 | $0 a month |
| 3 in 4 of the empties | 0 | $0 | $0 a month |
The last column is your own breakeven, not a quote. Anything that recovers those slots for less than that figure has already paid for itself.
The finding, in one sentence

Three things worth knowing before you act on this
- The slot is not the only thing you lost. A client who cancels and never rebooks stops buying entirely, so the yearly figure is a floor rather than a ceiling. This read deliberately counts only the slot.
- Refilling late costs more than it returns. A slot an hour away is rarely sellable, and chasing it still costs a message and somebody's attention. Any fix needs a minimum notice window below which it does not try.
- Measure the leak before you buy anything to plug it. The figure above comes from your own estimates. The version that holds up comes from your booking record, and that is a different and much shorter conversation.
How this was worked out. Contribution per appointment is the average ticket less what it costs you to serve one. Slots left empty are the ones that go empty less the ones you already refill. Everything else is that figure multiplied out over 52 weeks. No industry averages appear anywhere on this page and nothing is assumed about your business: every number on it came from the six figures you entered.
