The harshest math in appointment business.

Three numbers, multiplied — no softening factor

Factor	Where it comes from
Appointments booked per week	Your answer — midpoint of the range you pick
× estimated no-show rate	Conservative lookup keyed to your Coverage Score band — weaker confirmation/reminder/backfill, higher rate
× value of one appointment	Your answer

Note what's missing: a close rate. Our inquiry doors multiply by the odds a lead becomes a customer. This door doesn't, because a booked appointment already IS the sale — the chair, the staff hour, and the revenue were all committed. A clinic booking 85 appointments a week at a 15% no-show rate and $200 average: 85 × 4.3 × 15% × $200 ≈ $11,000 a month in revenue that was already on the calendar.

The no-show band is a conservative estimate keyed to your score, labeled as an estimate in every report; if you track your real rate, the report uses context accordingly. The measured discovery maps the flow that produces the rate.

The double cost nobody bills

An empty chair costs twice: the revenue that didn't happen, and the patient who was turned away last week because that slot was "taken." Practices that overbook to compensate pay a third time — in the waiting-room chaos of the days everyone shows. Defense beats compensation on every line.
