Churn Rate Calculator
Calculate monthly and annual member churn from cancellations, cohort size, and period length.
Churn is the metric that silently erodes MRR. This calculator converts your membership activity — starting members, cancellations, and new sign-ups — into monthly churn and implied annual retention.
- Monthly Churn = Cancellations ÷ Members at Start of Period
- Annual Retention ≈ (1 − Monthly Churn)^12
- HFA industry benchmark: 66.4% annual member retention
Built for gym owners tracking retention KPIs, evaluating programming changes, and preparing acquisition due diligence.

Frequently Asked Questions
How do you calculate gym member churn rate?
Monthly churn equals cancellations divided by members at the start of the period (for a single month). Over multiple months, divide total cancellations by starting members and by number of months for an average monthly rate.
What is a good churn rate for a gym?
Industry-wide annual retention is 66.4% per HFA — roughly 3–4% monthly churn. Budget gyms may run 5–8% monthly; boutique formats with strong community often achieve 2–4%.
How do churn and new sign-ups relate?
Ending members = Starting members − Cancellations + New sign-ups. You can grow while churn is high if sales outpace cancellations, but high churn increases CAC burden and caps LTV.
How do you convert monthly churn to annual retention?
Annual retention ≈ (1 − monthly churn)^12. At 4% monthly churn, implied annual retention is about 61%. This is a steady-state estimate; cohort retention curves vary in the first 90 days.
