What Is a Gym Member Worth? LTV Explained

Ask most owners what a member is worth and they will tell you the monthly dues. That is what a member pays this month. It is not what a member is worth — and the difference is the number your entire marketing budget should be judged against.

The Two Formulas

That is the whole model. If your monthly churn is 5%, the average member stays 20 months (100 ÷ 5). If your average member pays you $150 a month in total revenue — dues plus everything else they buy, divided across all members — that member is worth $150 ÷ 0.05 = $3,000 over their lifetime.

Two definitions matter here, and getting them wrong corrupts everything:

• Churn means canceled members — not members who stopped showing up. Attendance predicts cancellation; it is not cancellation. (The full breakdown is in How to Reduce Gym Member Churn.)
• ARM is average revenue per member — total monthly revenue divided by total members, not your rack-rate dues. A member body with strong personal training and add-on revenue is worth more per head than the dues sheet suggests.

The Order Matters: CAC and Churn First, Then Divide

Owners usually meet LTV as a trivia number. Used properly, it is a decision tool, and it only works in one order:

1. Know your CAC — what it actually costs you, all-in, to acquire one new member.
2. Know your churn — your real cancellation rate, measured the same way every month.
3. Then divide to get LTV — and judge every marketing dollar on LTV versus CAC.

If a member is worth $3,000 over their lifetime and costs you $300 to acquire, you have a business that can grow. If the same member costs $900 to acquire because your ads are untargeted and your follow-up leaks, the problem is not the member’s value — it is the machine around them. Without both numbers, you are guessing, and most owners guess in whichever direction feels better that week.

A Worked Example (Hypothetical — Your Numbers Will Differ)

Same gym. Same dues. Same members walking in the door. Each one is worth $2,000 more — in this hypothetical — because they stayed longer. Nothing about the example is a benchmark or a promise; it is arithmetic. Run it with your own dues and your own churn and you will see your own version of the same gap.

Churn Is the Lever That Moves LTV

Look at the formula again. There are only two ways to raise LTV: charge more per member, or keep members longer. Raising prices has a ceiling and a backlash. Churn does not — and churn is also the number that decides how hard your marketing has to work just to keep you flat.

That is why the work runs retention before acquisition in everything we do. A gym losing members at 5% a month needs a constant stream of new sign-ups just to stand still, and every one of those sign-ups costs money. A gym at 3% grows on the same marketing spend. Before you spend another dollar getting members, find out what the members you have are worth and how long they are staying: How to Reduce Gym Member Churn covers the system, and How to Get More Gym Members covers how to judge acquisition channels once the math is in place.

The Rule to Run Your Marketing By

Every marketing spend gets judged on LTV versus CAC. Nothing else. Not likes, not leads, not how busy the front desk felt. If you do not know your churn, you do not know your LTV, and if you do not know your LTV, you do not have a marketing budget — you have a habit.
