Gym ad cost per member calculator

Your real ad cost per member is everything you paid Meta or Google, GST included, divided by the people who actually paid for a membership. Not leads, not trials. With the example on load (₹15,000 before 18% GST, 100 leads, 30% come for a trial, 40% of those join), you pay ₹177 a lead, but each of the 12 new members costs ₹1,475. At ₹1,400 a month in fees, that's just over one month of fees to earn back.

The numbers are hypothetical, taken from the worked example in our Facebook ads for gyms guide. Replace them with yours; nothing you type leaves your browser.

What the calculator works out

• Cost per lead, per trial and per member (CAC). The same ad cost divided by people at each step of the funnel.
• Member lifetime value (LTV). Fees one member pays you over their stay.
• LTV : CAC. How many rupees of fees come back for each rupee spent getting the member.
• Payback. How many months of that member's fees it takes to cover what you spent to get them.
• The most you can pay per lead for the payback you want, at your own conversion rates.
• A what-if grid showing CAC if more leads came for a trial or more trials joined.

The formulas

If you only know clicks, leads = clicks × the share who filled the form or started a chat. LTV uses the common subscription shortcut, average revenue per user ÷ churn rate, which assumes a steady share of members leaves each month. The gym churn calculator works out your churn from member counts.

Without GST the example matches the guide exactly: ₹150 a lead, ₹1,250 a member and an LTV : CAC of 14.

Why GST on ads matters

Google's payments help says customers in India are charged GST at 18% (CGST 9% + SGST 9% within the same state, otherwise IGST 18%). Meta's help centre says ads bought in India are sold by Meta India and GST and TDS are added whenever you're charged; that page doesn't state a rate, so check it on your invoice and change the GST field if it differs.

Whether that GST is a cost depends on your own GST. Since September 2025 gym services are taxed at 5% without input tax credit, so for most gyms the GST on ads can't be set off and belongs in CAC. Tick "I claim input tax credit" only if your CA confirms you can. The gym GST calculator covers the fee side.

How to read your result

Judge ads by cost per member, never cost per lead. Cheap leads that never visit are expensive members. In the grid, drop the trial rate from 30% to 20% and the example CAC jumps from ₹1,475 to ₹2,213, with the same ads and the same spend. Same-day follow-up, a booked trial slot and a clear ask on the last day often move CAC more than any change to the ad. Our post on turning trials into members has the follow-up sequence, and the gym sales script has replies to "I'll think about it".

Payback is the number to set a budget with. The pill uses the rule of thumb from the Facebook ads guide: aim for a cost per member below one month's fee, and treat two or three months as acceptable only once you know members stay. LTV is fees, not profit. Rent, salaries and electricity come out of it, so a big LTV : CAC doesn't mean you can spend anywhere near the LTV.

LTV : CAC has no gym benchmark we can point you to. There's no published figure for Indian gyms. Track your own ratio month by month and by ad type (lead form against click-to-WhatsApp) and keep the one that's better.

"Most you can pay per lead" is your bidding guardrail. If Ads Manager shows a cost per result above it, that campaign won't pay back in your target time unless your trial and join rates improve.

What the calculator leaves out

• People who'd have joined anyway. Someone who saw your board for months and then clicked an ad gets counted as an ad join. Ask every joiner where they heard about you.
• Time to convert. Leads from the last week of the month may join next month. Use at least four weeks.
• Staff time and creative costs. Add any video shoot or agency fee to the spend.
• TDS. Meta's page says TDS is included in the charge and refunded as ad credit once you give them the TDS certificate. Not modelled here.
• Cost of serving the member. Payback is in months of fees, as in the guide. For profit after running costs, use the gym profit calculator.

There are no "typical cost per lead" figures here, on purpose. Costs vary by city, season, radius and offer, and we couldn't find a reliable published source for Indian gyms. Run a four-week test, log every lead and measure your own.
