Peak capacity is healthy
96 members train at peak (12% of 800) against a ceiling of ~63. Utilization 2% — the binding constraint is equipment throughput.
Levers before expansion
Peak demand fits inside capacity — protect it with slot rotation and class scheduling rather than adding capex.
Check the fleet cost behind this plan
Capacity math assumes the planner fleet — verify counts and CAPEX before promising access levels.
Open Equipment Planner →Assumptions
- • Equipment turnover: 3 users/unit/hour
- • Peak floor allowance: 2.5 sqm/person
- • Fleet density: 0.035 units/sqm
- • Peak share: 12% of members
Limitations
- • No class schedule — Group classes consume floor blocks not modeled here.
- • Uniform turnover — Treadmill sessions run longer than dumbbell circuits; blended average used.
Data sources & method
This tool is a calculation model, not a database lookup. It runs arithmetic on the numbers you enter, using an explicit formula and a small set of documented default assumptions (service intervals, energy prices, useful life). Every assumption it applies is listed in the result, and each one is a default you can overwrite.
We do not hold a benchmark dataset. FitnessNav operates no gyms, runs no fleet, and has never collected equipment telemetry, so there is no measured useful-life, maintenance-rate or downtime distribution behind these models. The default assumptions come from published manufacturer documentation and standard trade practice, and they are labelled as assumptions \u2014 not as findings. Treat the output as a structured way to think about a decision, and replace every default with your own numbers before it leaves your desk. If a vendor hands you a benchmark, ask for the sample size and the age of the machines in it.
Peak Capacity Calculator — frequently asked questions
How many members can my floor serve at peak?
Capacity is min(machine throughput, occupancy ceiling): units × 3 sessions/hour during peak hours, floored by 2.5 m² of floor space per member present.
My utilization reads 120% — what now?
You are turning members away at peak. Adding units lifts throughput one-for-one until you hit the floor-space ceiling — check the binding constraint shown in the result.
What utilization band is healthy?
40–90%. Below 40% you are over-capitalized on equipment; above 90%, queueing degrades member experience and drives churn.
Do enrolled members all show up at once?
No — only a slice attends simultaneously. The calculator applies your peak-share assumption (default 12%) to enrollment to estimate concurrent demand.
