Buying a Gym: the Membership Math Nobody Shows You Before You Sign

Should you buy a gym? You can — and the recurring-revenue pitch is real. But the number that decides whether the deal is good or a slow-motion fire isn't the membership count on the listing. It's churn. And the seller is not going to lead with it.

I'll say this part up front, cause it's where I'm coming from: I spent years inside this industry. I was CMO of a fitness franchise with 300+ locations, and CMO of a gym-management software company. I've watched the membership math from both the marketing seat and the operator seat, on a lot of clubs. So when I tell you the headline number on a gym listing is the one to trust least, it's not a hunch.

Buying a gym is one of the more seductive small-business deals out there. Monthly dues, members on auto-pay, a brand people already drive to. On paper it looks like the dream — recurring revenue you just collect. The trap is that "recurring" and "reliable" are not the same word, and the gap between them is the whole game.

Why the recurring-revenue pitch is half true

The industry itself is genuinely healthy. U.S. gyms and studios hit a record 77 million members in 2024, with facility membership up 5.6% that year — the strongest two-year run on record, per the Health & Fitness Association (the old IHRSA). IBISWorld counts over 107,000 gym and fitness-club operators in the U.S. People want this. The demand is not the question.

The question is what happens to the members already on the books. Here's the part nobody puts on the for-sale page: the average health club keeps about 71% of its members year to year — which means roughly 1 in 4 walks every single year. And about half of new members quit within the first 6 months. That's not a bad gym. That's the baseline. A normal, decently-run club is bleeding a quarter of its revenue a year and re-selling it back to itself just to stand still.

So "$400k in recurring revenue" doesn't mean $400k shows up next year on autopilot. It means the gym has to replace something like a quarter of that base — through marketing, sales, front-desk hustle — before it earns a dollar of growth. Recurring revenue with high churn isn't an annuity. It's a bucket with a hole in it, and the listing only shows you the water going in.

This is the single biggest thing I want you to walk away with. When you buy a gym, you're not buying the member count. You're buying the rate at which members leave, because that rate is what you'll be fighting for as long as you own the place.

Franchise vs. independent — pick your trade-off

Before the numbers, the fork. Most gym deals are one of two animals, and they're not the same purchase.

• A franchise (a Planet Fitness, an Anytime, a boutique brand) hands you a proven model, national marketing, and a playbook. In exchange you give up royalties, a franchise fee, and most of your freedom — you run their system, you don't reinvent it. You're also buying into a brand whose reputation you don't control.
• An independent is yours to shape — pricing, programming, vibe, all of it. More upside, more margin, but no brand pulling people through the door and no system to lean on. The membership base is whatever the last owner built, and it leaves with the relationships they had.

Neither is better. They diligence differently, though. With a franchise, a big chunk of your homework is the franchise agreement itself — transfer fees, remaining term, required remodels (those reinvestment clauses are brutal and easy to miss). With an independent, more of the value is locked in the current owner's face and habits, which is exactly the value most likely to walk out the door at closing. Know which risk you're signing up for.

The real numbers on buying a gym

Here's what an actual owner-operator gym sells for, not the fantasy version. On BizBuySell's gym and fitness-center benchmarks, the median established gym lists around $295,000, on median revenue of about $406,000 and owner earnings (SDE) around $100,000. That's roughly 2.9x cash flow, or about 0.75x revenue. These are small, hands-on businesses — not the empires the gurus post about.

A few things to sit with in those numbers:

• The revenue-per-member math is the engine. Take that ~$406k against the member count and you get your average revenue per member. If the gym claims 1,000 members and the revenue says you're collecting like there are 600, the gap is the story — those other 400 are frozen, comped, delinquent, or gone.
• Margins live and die on two fixed costs: the lease and the equipment. A gym is a big box full of expensive steel under a long-term lease. Those two line items anchor the whole P&L, and neither flexes when membership dips. When members leave, revenue falls — rent and the loan on the leg-press machines do not.
• Multiples sit on the lower end of small-business deals on purpose. Buyers price in exactly the churn problem we've been talking about. A 2.9x gym and a 2.9x deal in a stickier industry are not the same risk at the same price.

For how to actually pressure-test a number like SDE and the multiple, the valuation walkthrough goes deeper than I can here. The gym-specific point is just this: in this business, the multiple is mostly a bet on retention. So go verify retention.

Churn is the metric that decides the deal

If you take one habit from this whole piece, take this one. Before you fall for the member count, ask for the churn. The seller will quote you a gross number — "we've got 1,200 members." That number is close to meaningless on its own. The number that matters is how many of those 1,200 will still be paying in 12 months, and how much it costs to land the ones who replace the rest.

Why churn is the lever and not just a metric: the industry's own data says it costs 5 to 7 times more to acquire a new member than to keep an existing one. So a gym with high churn isn't just losing revenue — it's spending its biggest marketing dollars over and over just to refill the same seats. Two gyms can post identical revenue this year; the one with lower churn is worth dramatically more, because it keeps that revenue while the other one has to go buy it again. The price tag rarely reflects that. Your diligence has to.

This is also where the real upside hides, by the way. If you find a gym with sloppy retention — no onboarding, no follow-up, a front desk that never calls a no-show — that's not only a risk. It's a fixable one. Group-class and personal-training members stick around far longer than people who work out alone. A churn problem you know how to fix is the closest thing to an edge you'll get on a gym deal. But you only get to make that bet if you measured the churn first.

What to actually diligence before you sign

The gym-specific diligence list is short, and every item on it is a place sellers round in their own favor. Don't take the cover sheet on faith — make them prove each one.

• Real active members vs. claimed members. Pull the billing system, not the brochure. Active means paid this month, on a live card, not frozen and not 60 days delinquent. The honest count is almost always smaller than the listing number — find out by how much.
• The churn / retention trend, month over month for the last 12-24 months. One ratio isn't enough — you want the direction. A gym shedding members faster each month is a very different deal than one that's stabilized, even at the same headline count.
• Deferred equipment maintenance. Walk the floor. Treadmills are expensive and they wear out on a schedule. A seller can juice short-term profit by simply not replacing anything for two years, and you inherit the entire capital bill on day one. Get the age and condition of every major machine.
• The lease. Term remaining, renewal options, escalators, who pays for what. A gym with 18 months left on its lease and no renewal isn't a business — it's a countdown. The lease can be worth more or less than the equipment; treat it like a core asset.
• Prepaid and contract liabilities. Annual paid-in-full memberships, lifetime deals the last owner sold for cash, multi-year personal-training packages already collected. These are revenue you'll have to deliver without getting paid for it. They're a liability you're buying, and they belong in the price.

None of this is exotic. It's the same discipline as any acquisition — just pointed at the line items where a gym hides its problems. If you've read the laundromat breakdown, same idea, different machine: with a laundromat you diligence the equipment and the foot traffic; with a gym you diligence the equipment and the churn.

Size the local market before you fall in love with one gym

One more thing, and it comes before any single listing. A gym is a local business — its whole world is the few miles around the front door. The same gym is a great buy in an underserved, growing suburb and a terrible one three blocks from two newer competitors and a Planet Fitness undercutting everyone on price.

So before you anchor on a specific deal, understand the territory it sits in: how many fitness facilities already serve that radius, how the population and income are trending, whether the market is saturated or wide open. That's exactly what DealStratum's market analysis is for — it helps you size a local fitness market and see where it's crowded versus open, so you walk into a deal knowing whether the area can even support the membership math the seller is promising. It won't value the gym for you and it won't do your diligence — that's still on you and your advisors. It just makes sure you're not buying a great gym in a dead market.

The honest bottom line

Buying a gym can absolutely be a good deal. Real demand, real recurring revenue, often a fixable retention problem you can actually move. But it rewards the buyer who treats churn as the headline and the member count as the footnote — not the other way around.

Most people buying a gym fall in love with the recurring-revenue story and never ask what the bucket leaks. The ones who do well ask for the churn before they ask for the price, walk the equipment, read the lease, and count the active members themselves. Do that, and the membership math stops being the thing nobody showed you. It becomes the reason you got a fair price instead of an expensive lesson.
