Fitness studio capacity, formats and timetable planning for new owners
Shows how a new studio's weekly attendance ceiling comes from working capacity times sellable slots, with catchment tests, format comparisons and break-even figures.
What to take away
- Your weekly ceiling is working capacity (C) times genuinely sellable slots (S). An 18-mat room with 32 sellable slots holds 576 attendances a week.
- Rent runs during empty hours. Divide daily rent by daily sellable slots to see what each slot must earn.
- Test a catchment on footwalk-time radius, competitor count inside it, and the 6am member's shower-and-commute loop.
- Format decides capacity. Personal training sits at C of 1, small group at 4 to 8, cycling at 20 to 36, HIIT at 24 to 40.
- Settle rent per square foot, fit-out cost and break-even attendances before you sign.
Weekly capacity before floor area
A studio's revenue is capped by a timetable, not a floor plan. You rent a room and the hours in which people will use it. Most hours are worth nothing, because nobody in the catchment is free then.
Call working capacity C: how many people can train at once without the class getting worse. Call sellable slots S: class starts you can staff and fill each week. C times S is the attendance ceiling.
A room open 14 hours a day is available 98 hours a week and may support only 25 sellable starts. The 2pm slot sits empty because members are at work.

Example: eighteen mats and thirty-two slots
A 1,800 sq ft room takes 18 mats with 6 ft spacing. Weekday starts at 6:00am, 7:00am, 9:30am, 12:15pm, 5:30pm and 6:45pm give six a day, or 30 a week. Saturday adds three and Sunday two.
That is 35 on paper, trimmed to an S of 32 for holidays and instructor gaps. C times S is 18 times 32, or 576 attendances a week, about 400 at 70 percent fill.
At a typical secondary-market rate of $24 per sq ft per year, 1,800 sq ft costs $43,200, or roughly $118 a day. Add $40 for taxes and common area and the room must earn $158.
Spread over 4.6 daily sellable slots, each slot carries about $34 of rent. At $22 average revenue per attendance, two paying bodies cover that line. One does not.
Mats and rigs, not floor area, set C, and the equipment and setup guide covers what moves the number.
What you sell against a fixed capacity
Each product draws on the same C in a different way.
What the member buys
- Drop-in
- One attendance
- Class pack
- Prepaid attendances
- Capped membership
- A set number of classes
- Unlimited
- Access
Draw on C
- Drop-in
- One seat, once
- Class pack
- Seats claimed later
- Capped membership
- Predictable
- Unlimited
- Self-limiting in practice
Failure mode
- Drop-in
- Lumpy revenue, unmanageable peaks
- Class pack
- Unused credits become a liability
- Capped membership
- Cap hitters want more, light users feel overcharged
- Unlimited
- Heavy users cluster in peak slots

Unlimited pricing holds because most members attend far less than the price implies. Our breakdown of fitness studio prices and margins shows where that logic stops holding.
Catchment tests to run on foot
- Walk the 10-minute walk radius and drive the 12-minute drive-time radius on a weekday at 6am and 6pm.
- Count competing studios and commercial gyms inside each radius. Ten within a 12-minute drive is a crowded catchment. Two is a different business.
- Time the loop a 6am member facesleave home, train 45 minutes, shower, reach work. If it overshoots their morning window, that slot will not fill.
Footfall counts from a property agent will not answer any of this. The U.S. Small Business Administration's business guide sets out the market research sequence a new business should work through.
Occupant load can cap C below what the room appears to hold, because exit capacity and exit numbers follow occupant load under OSHA exit route rules. Ontario's fire code sets comparable limits.
Formats compared by capacity and price per head
Typical ranges in U.S. metros:
| Format | Typical C | Typical price per head | Capacity risk |
|---|---|---|---|
| Personal training | 1 | $60 to $120 a session | Instructor leaves and the revenue leaves |
| Small-group training | 4 to 8 | $25 to $45 a session | Needs a steady sign-up pipeline |
| Yoga, Pilates, barre | 12 to 24 | $18 to $30 a drop-in | Mat spacing caps C before the room does |
| Indoor cycling | 20 to 36 | $20 to $35 a class | Bike count is the hard ceiling |
| HIIT and circuits | 24 to 40 | $15 to $28 a class | One poor instructor reaches everyone at once |
Low-C formats concentrate risk in one instructor and one member. High-C formats spread it, but they demand a room, sound and equipment that hold up with a crowd.
Money to settle before the lease
Rent, fit-out and break-even belong in writing before you sign.
Typical secondary-market retail rent runs $18 to $35 per sq ft per year triple net, and prime urban storefronts run $45 to $90. Fit-out for a studio with plumbing, shock flooring and sound treatment usually lands between $50 and $150 per sq ft.
If fixed monthly costs are $9,000 and revenue averages $22 per attendance, the studio needs about 410 attendances a month, or 14 a day, before instructor pay and card fees. That is a floor, not a profit. Our profit margins and break-even analysis shows how the floor moves once those costs land.
Opening sequence and first timetable
- Measure working capacity with people in the room and mats down. Equipment and circulation usually cost a place or two.
- Draft the opening timetable and mark which slots carry the week. Treat the rest as filler until proven.
- Register the business and settle the tax setup. The IRS overview of starting a business covers the federal side.
- Confirm which permits and inspections apply. Our licensing and compliance guide lists the sequence to work through.
- Recruit instructors for the carrying slots first, and agree cover before the first class runs.
- Open with fewer classes than you can staff. Adding one is easy. Removing one teaches members the timetable is unreliable.
Common questions
How many classes should I open with?
Fewer than you can staff, weighted toward hours your catchment has free. A thin timetable that runs reliably reads as competence.
Is a bigger room better?
Only if you can fill the extra places in slots that already work. Extra floor area raises rent every hour and raises revenue only in the slots you fill.
What number should I watch in the first year?
Attendances per sellable slot in your peak hours, tracked weekly. It shows whether the business works before the membership count does.
Can I plan around members who never come?
Observe them, but do not treat their revenue as durable. A member absent for six weeks is a cancellation not yet processed.
