Industry benchmarks for Online Fitness Memberships
Online fitness memberships need CAC back in roughly 4 months, because monthly churn of 8 to 14 percent leaves a narrow runway. CAC runs $50 to $140 per member with heavy dependence on creator partnerships and paid social, and January acquisition costs behave nothing like July. ARPU sits at $19 to $49 per month at 75 to 88 percent gross margin after content production, streaming, and payment fees. At $90 CAC against $23.20 in monthly gross profit, payback is 3.9 months, so a member who quits at month 3 was never profitable.
The first 90 days decide everything, because habit formation and not content library size drives retention. Members who complete 3 or more sessions in their first two weeks retain at several times the rate of those who do not, which makes onboarding programming and early accountability the highest-return investment available. Annual prepay is the second lever, converting a volatile monthly cohort into guaranteed revenue and cutting effective CAC payback to the first invoice. Seasonality also demands cohort-level tracking, since January cohorts churn faster than any other month and will distort a blended average.
Frequently asked questions
CAC Payback Estimator for Online Fitness Memberships, answered.
Why is fitness churn so much higher than SaaS?
Because consumption is effortful and discretionary. Members cancel when the habit lapses rather than when the product fails, so engagement frequency predicts churn better than satisfaction scores.
Does a free trial improve or hurt payback?
It usually improves it if the trial requires a card and includes guided onboarding, because trial users who form the habit convert and retain. A no-card trial mostly inflates CAC per paying member.
How should I handle January seasonality?
Track cohorts by acquisition month rather than blending. January cohorts are large but churn fast, and averaging them into your baseline will make your retention look worse than it is the rest of the year.
