The retention math that decides if your studio survives

Industry monthly churn runs about 4–8% (top studios hold 2–3%), it costs roughly 5–7× more to acquire a member than to keep one, and ~50% of new members quit within the first 90 days. Run that math forward and the conclusion is brutal: most studios are filling a leaking bucket with expensive water.

The lever isn’t a bigger ad budget. It’s the first 30–90 days — onboarding, early wins, and the habit loop that turns a trial into a member. The payoff is outsized: a 5% lift in retention can raise profit more than 20%, and members who pass the 90-day mark are roughly 3× more likely to stay a full year.

The takeaway is operational, not promotional: win the first 30–90 days with structured onboarding and early wins, and the retention math stops working against you.
