Fitness sells subscriptions, so first-transaction lead math barely applies: a $50 to $200 monthly membership means the value of a lead is almost entirely in retention months, and the industry's famous churn is the variable that decides everything. A member lasting four months and one lasting fourteen are different businesses acquired through the same lead.
Boutique studios (training gyms, pilates, group fitness) run the strongest economics for paid leads: higher monthly rates ($150 to $300), onboarding that builds habit, and communities that hold members past the one-year mark. Big-box-style pricing at $30 a month needs volume and floor efficiency that paid leads rarely deliver; the boutique model is where this calculator's bands genuinely fit.
Trial structure is this vertical's close-rate story. Paid trials ($21 to $49 for two or three weeks) convert a smaller top of funnel at much higher member-conversion rates than free passes, and the paid-trial cohort churns slower afterward. Enter your lead-to-member rate for whichever trial model you actually run; mixing a free-pass close rate with paid-trial economics is the standard way gyms fool themselves.
Worked example
A worked example: a training studio at $180 a month and 70% margin keeps $126 per member-month. With members lasting an average of ten months, a joined member is worth $1,260 in kept revenue; closing 30% of leads to joined members makes a lead worth $378 on lifetime math, and even the divide-by-three ceiling ($126) sits far above the market band. The same studio measuring only first-month value would compute a $13 ceiling and wrongly conclude ads cannot work.
The January caveat: fitness demand spikes every new year, lead prices rise with it, and the January cohort churns faster than any other. The best-performing studios treat January as a volume month and September as a quality month, budgeting for both instead of annualizing either.
