What is lead-to-member conversion rate?
Lead-to-member conversion rate is the share of leads who became paying members: members divided by leads, for the same period and location. It is the number that decides whether a cheap lead was cheap at all.

The lead-to-member conversion rate for gyms
A lead is a name and a number that came in through an ad. A member is a person who paid. Between the two sit the front desk calling back, the consult being booked, the person turning up and the sale being closed, and every one of those steps loses people. Lead-to-member conversion rate is the share that made it all the way: members divided by leads, counted for the same campaign, period and location.
It changes the price of everything upstream. Two sources can produce leads at the same cost and members at wildly different costs, because the rate at which their leads become members is different. A cheap lead is not a cheap member. Ad platforms report the first number and cannot see the second, which is why a campaign with a falling cost per lead can be getting more expensive per member every month.
Where it misleads: timing and sample size. Leads from the last week of the month become members next month, so a month-end read always looks worse than the truth; give leads a fixed window to convert, and compare like with like. Ten leads tell you nothing. Read the rate over enough leads and by source, beside show rate and cost per member, which is what the rate is really for.
How Adsu uses the lead-to-member conversion rate
Adsu carries leads and members for every campaign at every location on the same line, and the members column is verified payments from your billing system, not a stage someone marked in the CRM. Adsu counts verified stages only: if a stage cannot be verified, it is not counted. Every report is one line per campaign per location. Booked and showed sit between the two, so when the rate is low you can see which step is losing people.
Adsu credits the last eligible touch inside the 30 days before the payment. Booked, showed and paid go back to Google as offline conversions and to Meta through the Conversions API. The platforms then learn who becomes a member rather than who becomes a lead, and the rate moves from the ad side too: the same spend starts producing leads who convert.
Questions, answered.
Yours, by source, is the only one that matters. Rates differ with the offer, the price, the speed of follow-up and how much intent the source sends, and none of that transfers from another gym. Work out what rate you need from your cost per lead and the most you can pay for a member, then compare each source against that.
Divide the number of new paying members by the number of leads that produced them, for the same period, source and location. In the example above, 12 members from 100 leads is 12%. Count each person once, count members only when payment clears, and give leads a fixed window to convert so one month compares with the next.
Because cost per lead only measures the ads, and the rate measures everything after them. Either the source is sending people with no intention of joining, or the front desk is losing them between the enquiry and the sale. Track booked and showed separately: if leads are not booking, look at follow-up; if they book and do not show, look at confirmation; if they show and do not pay, look at the offer.
