The Real Economics of Running a Modern Gym (We Audited 120 of Them)
We pulled anonymized P&Ls from 120 independent gyms across Europe and North America. The headline: the average facility leaves 31 percent of revenue on the table. Inside, the four levers that moved the needle most and why the best operators all had one thing in common.
The data set
Between mid 2024 and the end of 2025, we collected anonymised twelve month profit and loss statements from 120 independent gyms. The sample skewed slightly toward facilities in the 200 to 800 member range, with locations across the UK, Germany, France, the United States, and Canada. We excluded chain franchises, boutique studios under 80 members, and any facility that had been open for less than two years.
The headline finding was uncomfortable. The average gym in the sample was operating at roughly 69 percent of its theoretical revenue capacity. Put differently, 31 cents of every potential dollar was never being collected. That gap was not, in most cases, a product of weak marketing. It was a product of four operational leaks.
Leak one: silent churn
The average gym in our sample lost 4.1 percent of its members each month. The top performing facilities lost 1.7 percent. The difference is not small. Over a year, the difference between a 4 percent monthly churn rate and a 2 percent rate is the difference between needing to replace your entire membership every twenty months and needing to replace it every fifty.
The striking finding was that members rarely told anyone they were leaving. In most cases they simply stopped attending, kept paying for a month or two, and cancelled by email. By the time the cancellation came in, the relationship was already irretrievable.
The top performing operators had a structured at risk intervention. When a member missed two scheduled sessions in a row, a real human reached out within 48 hours. Not a marketing email. A short, personal message. The intervention cost almost nothing and reduced cancellations from that segment by roughly two thirds.
Leak two: untracked guest passes and trials
The second largest revenue loss was almost invisible in the accounts. Free guest passes, social media trials, and informal walk ins were generating significant member acquisition cost without an attached conversion process. The average gym was converting under 8 percent of trial visitors into paying members. The best in our sample were converting over 30 percent.
The difference came down almost entirely to whether a trial visitor was assigned a named staff member with a defined follow up sequence, or whether they were simply allowed to use the facility and asked at the desk how it went. The structural change was small. The revenue impact was enormous.
Leak three: off peak under utilisation
Most gyms in the sample were running at over 90 percent of capacity between 6 and 9 in the morning and 5 and 8 in the evening. The middle of the day was empty. The cost structure of a gym, however, is largely fixed. An empty 11am hour costs almost exactly the same to operate as a packed 6pm hour.
Operators who introduced off peak only memberships at a meaningful discount, or partnered with corporate wellness programmes, freelancers, and shift workers, were able to fill 60 to 70 percent of those hours within six months. The marginal revenue was almost pure margin.
Leak four: invisible member progress
The final and most surprising finding was that the single biggest predictor of retention across the entire sample was whether members had visible, trackable evidence of their own progress. Gyms with structured assessments and member facing dashboards retained members at nearly twice the rate of those without.
Members do not stay because they love the gym. They stay because they can see themselves becoming the person they wanted to be. Operators who treated member progress as a product, not a coincidence, won every retention metric we measured.
The one thing the top performers all had in common
It was not branding. It was not equipment. It was not even price positioning. It was a written, repeatable operating system for member experience. Standard operating procedures for the front desk, structured onboarding sequences, defined at risk interventions, and a regular cadence of progress reviews. The top facilities ran their gym the way a good restaurant runs a kitchen. The rest improvised.
