Every recovery modality a gym can add, with real equipment pricing and the honest
evidence grade. Change the four numbers below and every payback period recalculates live.

How are you charging?
Tier gating has the best take-rate leverage. A-la-carte suits appointment-shaped services.

How each number is built
Tier revenue = members × take rate × tier price, split across the modalities in your
tier. A-la-carte revenue = sessions/day × that modality's typical price × 26 days.
Net subtracts real monthly opex — energy, water, chemicals, consumables, testing labour.
Payback = total install cost ÷ net monthly. Equipment prices are current published
commercial pricing, not MSRP guesses.
What the evidence grades mean
Strong — replicated human trials or large long-term cohort data.
Mixed — real effects reported but inconsistent across studies, or the strongest
evidence is for a different use case than the one being sold.
Weak — very few studies, poor quality, unpublished, vendor-funded, or explicitly
flagged as unproven by a regulator. A fast payback on a weak-evidence modality is still a real
business risk: it is the one your best-informed members will ask you about.
Three things this calculator can't model
1. Health-department cost. Cold plunge and any shared water feature fall under public
pool/spa code — permits, daily chemistry logs, CPO certification. Call your AHJ before you order.
2. Throughput ceilings. A float pod serves one person for 60–120 minutes. A sauna serves
six for fifteen. Two modalities with the same payback here can have wildly different revenue ceilings.
3. Whether anyone actually shows up. Every model here assumes you can fill the sessions.
That's a marketing question, not an equipment question.
