Gym marketing budget calculator.

The percentage-of-revenue approach

The simplest way to set a marketing budget is to make it a fixed share of revenue, so it grows when you grow and shrinks when you shrink. The question is which share.

7.7%

The most solid public reference point is Gartner’s annual CMO Spend Survey. Its 2025 edition found marketing budgets sitting at 7.7% of overall company revenue, flat for a second year. Read the fine print before you use it: that survey covers roughly 400 marketing leaders across North America and Europe, most of them at companies turning over more than a billion dollars a year. It is not a gym number and nobody should present it as one. It is useful for one thing only — it tells you the order of magnitude that serious businesses land on, and that order of magnitude is single-digit percentages, not 30% and not 1%.

We use 10% of monthly membership revenue as the working figure in the calculator above. That is our judgement, not a published benchmark, and here is the reasoning. A gym is a fixed-cost business: once the rent is paid and the coaches are on the floor, the next member costs you very little to serve. That makes growth worth more to a gym than to the average company, which argues for running above the cross-industry number. On the other side, a gym has no cash cushion to speak of and cannot wait two years to be proven right, which argues for restraint. Ten percent is where those two pressures meet. If you are genuinely full and running a waiting list, three or four percent to keep the pipeline warm is plenty. If you have just signed a lease on a second location, you will run far above ten for a season and you should know going in that you are doing it.

The lifetime-value approach

The percentage approach tells you what you can afford. It does not tell you whether the spending is working. For that you need to know what a member is worth, and that number is governed almost entirely by how long they stay.

66.4%

The Health & Fitness Association’s 2025 Fitness Industry Benchmarking Report — drawn from 175 companies and more than 17,000 facilities across 27 countries — puts the industry’s average member retention rate at 66.4%. Put the other way round, roughly one member in three cancels over the course of a year. That is the average across an industry that includes big-box chains with low fees and low engagement, so a well-run coaching gym should beat it comfortably — but it is the only figure on this page we would call a real industry benchmark, and it is worth sitting with. If a third of your members leave every year, a third of your marketing budget is doing nothing but standing still.

This is why the calculator asks for churn before it asks what you want to grow by. Churn sets member lifetime, lifetime sets lifetime value, and lifetime value sets the most you can rationally pay for a new member. A gym at 2% monthly churn can afford to pay roughly twice as much per member as a gym at 4%, competing for the same clicks in the same town. That gym wins, and it does not win because it is better at advertising.

Why the ceiling is not the target

The second number the calculator gives you is a ceiling: the most you can pay for a new member before the member stops being worth what you paid. It is not a goal. If you spend exactly your ceiling you have converted a growing gym into a break-even one and handed the upside to Meta. Treat it as the line you check against, not the line you aim for. A healthy gym pays somewhere well under half of it.

The third number, payback, is the one that actually bites. Marketing spend goes out in a lump this month. Membership fees come back a hundred dollars at a time over years. A campaign can be excellent on a lifetime basis and still put you in an overdraft, because lifetime value is not a cash-flow statement. If the calculator hands you a payback period longer than about six months, the honest read is that you can afford the strategy but not the timing, and you should spend less per month for longer.

What counts as the marketing budget

Everything that exists to bring in members. Ad spend, whoever manages it, the software that follows up with leads, the cost of making the creative, and the price of the website if it is being rebuilt to convert. If you run the ads yourself, put an honest value on your own hours in there too — the cheapest-looking option on paper is usually the one where the owner is doing four hours a week unpaid and calling it free.

We split this into the management fee we charge and the ad spend you pay to the platforms directly. For budgeting purposes they are one number, and the calculator above treats them as one number. Not sure whether to hire at all? Agency or DIY?

What we left out, and why

You will notice the calculator never tells you what a lead or a signed member should cost in your market. That is the number everyone wants and it is the number nobody can source honestly. The figures circulating for gym cost-per-lead come from agency blog posts quoting other agency blog posts, and they vary by a factor of ten depending on city, offer and season. We could have invented a plausible-looking average. Instead the calculator tells you what your own numbers can support, and leaves the market price for you to discover by running ads — which is the only way anyone ever actually finds it out.

The same goes for the rules of thumb inside the tool. One third of lifetime value, a six-month cash cap, ten percent of revenue: those are ours, they are stated openly in the working above, and if your accountant wants to argue for different ones, they may well be right about your gym.
