Tips from gym owners
- Gyms average 4–7% monthly churn. Under 3% is excellent.
- The biggest churn driver is attendance dropping to zero. Message members after 14 days away.
- Annual plans, automated renewals and a member app each reduce churn measurably.

Gym member churn calculator: FAQ
What is a good churn rate for a gym?
Monthly churn between 3% and 5% is good for a gym; under 3% is excellent. At 5% monthly churn you lose about 46% of your members over a year, so retention has a bigger effect on revenue than most marketing.
How do I reduce gym member churn?
Track attendance and contact members who stop coming, automate renewals and payment reminders, sell longer plans, and build community with classes and challenges. Software like Tuckly automates the first three.
