Every ad platform will tell you what a lead cost. None of them will tell you what a member cost, because none of them knows who joined. That second number lives in your booking platform, and the division that connects the two is yours to do.
It is one division, and it is easy to do badly. Pick the wrong month and the answer swings by half. Leave out the hours your desk spends on the phone and it flatters you. Stop at the join date and it counts a member who left in week five the same as one who stays three years. This piece works the whole thing on one invented studio, Alturra Studios, with 240 members at $169 a month. Swap in your own figures as you go.
Acquisition cost in one minute
- Use a quarter, not a month. Members join weeks after the money was spent, so one month divides this month's cost by last month's results.
- Say what is in it. Ad spend only, or everything spent to win a member. Both are legitimate. Mixing them between months is not.
- Judge it by payback. Cost per new member divided by monthly dues is how many months growth has to be funded before it funds itself.
- Then ask who stayed. A member who leaves in week five was not acquired. She was rented.
| Version | The sum | In the example | Use it for |
|---|---|---|---|
| Ad spend only | marketing spend ÷ all new members | $10,000 ÷ 57 = $175 | the monthly check, on a rolling quarter |
| Fully loaded | (spend + follow-up time) ÷ all new members | $11,400 ÷ 57 = $200 | deciding whether growth is really profitable |
| Paid only | spend ÷ members who came from an ad | $10,000 ÷ 30 = $333 | deciding whether to raise the ad budget |
| Payback | cost per new member ÷ monthly dues | $175 ÷ $169 = 1.0 months | how much cash growth ties up |
| Per member who stayed | spend ÷ members still paying at day 90 | $8,100 ÷ 27 = $300 | the honest version, read a quarter late |
What is customer acquisition cost for a fitness studio?
It is what the studio spends to win one new member. Acquisition spending on top, new members underneath. The reason to calculate it is to set it beside two other numbers you already have: what a member pays each month, and what a member is worth over her whole stay. A cost means nothing until it is next to the thing it bought.
Two definitions have to be fixed before the division means anything. A new member is someone who started paying dues in the period. Not a renewal, not a member switching plans, not a class pack buyer. If your studio counts a paid-in-full pass as a membership, count it here too, and count it the same way every quarter. And acquisition spending is money spent to bring in people who are not yet members. The newsletter to existing members, the retail display and the instructor's training course are real costs. They are not this cost.
How do you calculate CAC, and what goes in it?
Acquisition spending divided by new members, over the same period. The denominator is a count. The numerator is a choice, and there are three honest versions of it. They answer different questions, so decide which one you are quoting and label it.
- Ad spend only: $175. The easiest to keep, because it comes straight off the P&L. Its weakness is that it treats the phone calls as free.
- Fully loaded: $200. Alturra's desk spent about 70 hours in the quarter following up leads and intro offers. At $20 an hour that is $1,400 of payroll that exists only to win members. Add the freelancer who runs your ads, printing and event costs here too if they sit outside the marketing line.
- Paid only: $333. Of the 57 who joined, 27 came from a referral, a walk-in or a Google search that cost nothing. Sam, the owner, knows this because the signup form asks how each person heard of the studio. Dividing ad spend by the 30 who came from an ad gives the real price of a bought member.
The gap between $175 and $333 is the most useful thing on the page. The blended figure looks cheap because referrals and reputation are doing nearly half the work for free. If Sam doubled the ad budget, the new members would arrive at something closer to $333 than $175. A blended number tells you how the business is doing. A paid number tells you what more spending will cost.
Why does CAC swing so much from month to month?
Because the spending and the joining happen in different months. Someone who sees an ad in February becomes a lead in February, starts a 30-day intro, and joins in March. Divide February's spending by February's joiners and you have divided this month's cost by last month's harvest.
Follow February's money to see the lag. Alturra spent $3,495 that month and got 90 leads. Fifteen of them started an intro offer. Nine became members, and every one of the nine joined in March. Meanwhile the 15 people who did join in February were mostly January's intros finishing their 30 days. The funnel piece follows that February group step by step.
The cure is a longer window. Three months is long enough for most of the people a dollar bought to have joined, and short enough to notice a change. Roll it forward monthly: drop the oldest month, add the newest, and compare the result with last month's reading.
What is a good CAC for a fitness studio?
One your own dues pay back quickly. Any figure quoted from outside was built on another studio's prices, its definition of a member and its mix of free and paid sign-ups. The test that travels is payback: cost per new member divided by monthly dues.
Payback matters more than any ratio because a studio runs on cash. Every new member is money paid out now and collected later. With a one-month payback, growth pays for itself almost as it happens. With a six-month payback, each new member is a loan the studio makes to its own future, and a strong month of sign-ups can leave the bank account lower than a weak one.
Then compare with yourself. Keep the last four quarters on one line. A cost per new member that climbs for three quarters while spending is flat is telling you that conversion is slipping, and the place to look is the funnel, not the ad account. If your dues are far below your costs per member served, use the margin version: divide by the dues left after the cost of serving her. The margin piece shows how to find that figure on a closed month.
Does a member who leaves in a month count?
She counts in the cost. She should not count in the result. Standard CAC stops at the join date, which is exactly where the interesting part begins. A January sign-up who cancels in February cost the same $175 and paid back $169. Read the figure again for a group old enough to judge.
This version arrives a quarter late and it is worth the wait. It joins two numbers that are usually kept in different rooms: what marketing spent and how many of the people it bought are still members. A campaign that brings in cheap sign-ups who leave is expensive. A slower channel whose people stay is cheap. You cannot see either from the join date.
Should you track it blended or by channel?
Cost per lead by channel, cost per member blended, unless you record the source yourself. Ad platforms can count the leads they sent. They cannot follow those leads into your booking platform and see who joined, so a "cost per member" for each channel has to be built from your own records.
That is a limit worth respecting. The honest way past it is a field on the signup form, "how did you hear about us?", filled in for every new member, and a tally at the end of the quarter. It is imperfect, because people forget and guess, but it is yours. The channel comparison piece works that tally through for February and shows why the channel with the cheapest leads is not always the one with the cheapest members.
What to do this week:
- Total the marketing line for the last three closed months. Note what is in it.
- Count the people who started paying dues in the same three months. Divide.
- Divide the result by your average monthly dues. That is your payback in months.
- Add a "how did you hear about us?" field to the signup form if it is not there, and make it required.
- Put a reminder in the calendar for the same day next month. One reading is a number. Two is a trend.
Once you know the cost, the next question is what to do with it. The marketing budget piece turns payback into a monthly spending figure, and the four lists you already have are the members who cost nothing to reach. In the order of work set out in the four growth levers, buying leads comes last for exactly this reason: it is the only lever with a price per member.
Where this lives
The division is simple. What takes the time is getting both halves from different systems, on the same dates, every month. That is the part Xyzios keeps current. It works with Mindbody and is an approved Mariana Tek integration, and it connects to Google Ads and Meta. It shows spend, leads and cost per lead for each channel, side by side and never blended, because the two platforms count different events. And it shows one cost per new member: ad spend divided by the new members your booking platform recorded. It does not attribute members to a channel. The Sales Desk lists the leads and intro-offer holders worth a call each morning, for a person to work, which is the cheapest way to lower the figure: more members from the leads already paid for. How lead follow-up works covers that list.
Run your own quarter first. The churn calculator shows what each point of monthly churn does to a member's stay, which is the other half of what a member is worth, and the two-minute studio check will show which number your studio is missing.
