Reformer room revenue calculator
Before you sign the lease, see whether the room can actually pay for itself. Spots × classes per week × fill rate × drop-in price, modelled across weekly, monthly, and annual horizons, with a per-reformer productivity number to argue against rent.
For a 10-reformer boutique room
With 10 reformers, 28 classes per week, 75% average fill rate, and a £24 blended drop-in price, the room generates roughly £5,040 per week, £21,840 per month, and £252,000 per year across 50 trading weeks. Per-reformer productivity is roughly £25,200/year — the number to take to a lease conversation. Adjust the inputs below for your room. Last reviewed 21 May 2026.

Useful for lease math — does the per-spot annual revenue cover the cost of the reformer, share of rent, and cleaning?

75%
Mirror of your fill rate. If you push this above 85% consistently you'll need a waitlist strategy or more classes; below 50% means demand is the bottleneck, not capacity.
The math, spelled out
Weekly revenue = spots × classes/week × fill rate × drop-in price. Monthly = weekly × 52 ÷ 12. Annual = weekly × weeks open per year. Per-reformer productivity = annual ÷ spots, which is the number to drop into a lease conversation when your landlord asks why this square footage is worth it.
FAQ
What fill rate should I plan for?
For pre-open studios in a city with established reformer demand, plan for 45–55% average fill rate in the first six months, climbing to 65–75% by month 12 if marketing and retention are healthy. Mature studios in strong locations run 70–85%. Above 85% sustained is rare — at that point you're capacity-constrained and need a waitlist strategy. Plan your lease against your six-month number, not your year-two ceiling.
How many classes per week is realistic?
A six-day-a-week studio with 4–6 daily class slots runs 24–36 classes/week. Add early-morning (6am) and evening (7pm) slots if your area supports them. Under 20 classes/week makes per-reformer productivity hard to justify; over 50 means you need at least 2–3 instructors covering the schedule, which adds payroll.
Should I include memberships in 'drop-in price'?
Yes — use a blended per-class number. If most clients are on 8-class packs at £160 (£20/class) and unlimited members effectively pay £15/class, your blend is somewhere between. The calculator wants a single number that represents what the average bum on the reformer pays per session.
What about appointments and one-to-one sessions?
This calculator is for group reformer classes only. One-to-one sessions are a separate revenue stream with different economics (higher hourly rate, but only one client per slot). If 1:1s are a meaningful part of your revenue model, model them separately and add the two numbers.
