Watch the math run.
Enter three numbers about your practice. These are the same formulas from The Med Spa Money Map — the rebooking gap, the no-show waterfall, dormant-patient reactivation, and the membership math — with your figures in the boxes and the book's conservative discipline applied.

The four formulas, with your numbers
Each shows the raw formula result, then the range the book would actually put in a report — discounted for ramp, partial capture, and overlap.
Prebooked patients retain ~70%; un-prebooked ~30%. Most practices prebook ~40% of visits at checkout against a healthy 60%.
No-shows run ~14% in a typical practice against a <10% target. Reminder sequences and deposit policies recover roughly 40% of the gap.
Reactivating a lapsed patient costs $20–$60 against $100+ to acquire a new one, at a 10–20% response rate. We estimate your dormant list at one year of new patients — most established practices have more.
Members visit 2.9× more often and spend 35% more. A typical practice runs membership under 10% of revenue against a healthy 20–30% — the math below only moves you to 15%.
Two leaks this page can't calculate
These four formulas cover four of the book's six leaks. The other two — GLP-1 & weight-loss retention (usually the single largest, Chapter 10) and consult conversion & follow-up (Chapter 5) — depend on program and pipeline numbers a three-field calculator can't responsibly estimate. Pricing & discount integrity (Chapter 9) needs your promo mix.
The free diagnostic scores all six in about 90 seconds. If weight loss is a meaningful share of your revenue, the GLP-1 Retention Breakdown runs the Chapter 10 math on its own.
The numbers behind the math
Every benchmark is sourced and worked in The Med Spa Money Map, Chapters 5–9 and Appendix A. The presented ranges apply the book's conservative discipline: ramp time, partial capture, and the cadence cascade counted once.
