What is churn rate for a gym, and how do you calculate it?
The answer
Gym churn rate is the share of your members who leave in a period, usually a month. Divide the number of members whose plans ended without renewal during the month by the number of active members at the start of that month, then multiply by 100.
Churn is the opposite of retention: the members you lose rather than the members you keep. For a gym, where income depends on people renewing plan after plan, it is one of the most important numbers to know.
The formula
A member “leaves” when their plan ends and they do not renew within your grace period, for example seven days. Use the count at the start of the month as the base, before adding anyone who joined during it.
A worked example
A gym begins October with 320 active members. During October, 24 members’ plans end without renewal, and 20 new members join.
- Churn rate: 24 ÷ 320 × 100 = 7.5%
- Members at the end of October: 320 − 24 + 20 = 316
The 20 new members do not change the churn rate. They are counted in November’s starting figure instead.
What churn tells you
Two quick calculations make the number useful.
How long a member stays, roughly: 1 ÷ churn rate. At 7.5%, the average member stays about 1 ÷ 0.075 = 13.3 months. Treat it as a rule of thumb, not a promise.
Where membership is heading: joins ÷ churn rate gives the level at which joiners and leavers balance. With 20 joins a month and 7.5% churn, that is 20 ÷ 0.075 = about 267 members. This gym has 320 today, so at these rates it will slowly shrink towards 267, even though it is signing up 20 new people every month. You can test your own numbers in the gym membership revenue calculator, and our guide on calculating gym membership revenue shows what a lower churn rate is worth in rupees.
What to leave out
- Frozen members. A paused plan is not a departure. Keep frozen members out of both the leavers and the starting count while they are paused.
- Late renewals within your grace period. If a member renews a few days after their end date, they did not leave.
- Transfers between plans. A monthly member who moves to an annual plan has renewed, not churned.
Common mistakes
- Dividing by the end-of-month count. New joins inflate it and make churn look lower than it is.
- Counting only cancellations. Most gym members do not cancel; their plans simply end. Count non-renewals.
- Looking at one month alone. Churn moves with seasons, exams and festivals. Compare the same month across years, or use a three-month average.
Churn falls when renewals are followed up and absent members are noticed early; see our guides to tracking renewals and attendance tracking, and the glossary entry on churn.
