The math nobody runs: what a BJJ gym is actually worth per member

Ask a BJJ gym owner what their average member is worth, and most of them will give you a guess. Some smaller percentage will compute it on the fly using monthly dues times some number of months. Almost none will give you a real number, because almost none have run the math.

This is a problem, because the math determines almost everything else: how much you can spend acquiring a member, what your pricing should be, which programs are actually profitable, and whether your gym is on a sustainable trajectory or a slowly compounding loss-leader.

This post is the math. What lifetime value actually means for a BJJ gym, how to calculate it, what the typical numbers look like, and what they imply for the decisions you make every week.

The basic equation

Member lifetime value (LTV) for a recurring-revenue business is conceptually simple:

LTV = (average monthly revenue per member) × (average lifetime in months) × (gross margin)

The complication is that BJJ gyms have multiple revenue streams per member, not just monthly dues. A real LTV calculation for a BJJ gym needs to include:

• Monthly membership dues
• Add-ons (privates, gear, supplements)
• Event participation (seminars, in-house tournaments, belt ceremonies if monetized)
• Retail purchases
• Family billing co-revenue, if the member is part of a household account

Multiply that combined per-month figure by the average member lifetime, then apply gross margin (membership revenue is typically high-margin; retail and gear are lower). What you get is the actual economic value of an average member to your business, which is the number every other decision should be built on.

What the numbers typically look like

For a representative BJJ gym in the US, the math runs something like this for an average adult member on the standard tier:

• Monthly dues: $200
• Add-ons (privates spread across the population, gear, etc.): $30/month average
• Events spread across the year: $15/month average
• Retail spread across the year: $10/month average
• Combined monthly revenue per member: ~$255

If average member tenure is 18 months (which is typical of fitness more broadly, and BJJ runs slightly higher because of the slow-progression dynamic):

• Total revenue per member: $4,590
• At 60% gross margin (a conservative estimate for membership-heavy revenue): LTV ≈ $2,750

If you can move tenure to 24 months instead of 18 — through retention work covered in BJJ gym retention — the LTV jumps to $3,672. That’s a 33% increase in the value of every single member you acquire, with no change to pricing or acquisition tactics.

If you can also move add-ons from $30 to $50 (more privates, more retail, family billing on more accounts) — covered partly in the pricing post — at the new 24-month tenure, LTV becomes $4,464. That’s 60% more value per member than the starting baseline, just from operational tightening.

These are not heroic numbers. They’re the difference between a moderately-run gym and a well-run gym, and they compound across every member the gym acquires.

Why the LTV figure changes how you think

Knowing your real LTV changes three operational decisions in non-obvious ways.

It changes how much you can spend to acquire a member. A common heuristic is that customer acquisition cost (CAC) should be no more than one-third of LTV — that is, you can afford to spend up to about $900 to acquire a member with $2,750 LTV. Most BJJ gyms spend essentially zero on paid acquisition because they don’t know what they can afford. Once you know the number, the question shifts from “should I spend money on marketing” to “what’s the highest-ROI way to spend a tenth of my LTV per acquired member.” That’s a different question, and it usually opens up acquisition channels (paid search, sponsored events, partnership marketing) that the gym had previously dismissed.

It changes how you evaluate pricing changes. Owners look at a 5% pricing increase and think about the immediate dollars per member per month. The right framing is the LTV impact: a 5% price increase on a member with $2,750 LTV adds about $137 to their lifetime value, with minimal effect on tenure if the increase is communicated well. Across 100 new members per year, that’s $13,700 of additional annual margin, in perpetuity, from a single pricing decision. The cumulative effect of running underpriced for years is large enough to be a meaningful share of why some gyms struggle.

It changes how you allocate retention investment. A check-in call to a 14-day member that has even a 10% probability of saving them is, on a $2,750-LTV basis, worth $275 in expected value to the gym. A 10-minute call that has even a small chance of producing $275 is wildly worth doing. Most gyms don’t make the call because the cost-benefit math is invisible to them. Once they see it, the math becomes obvious — but only after running the LTV.

What the math reveals about specific programs

Running LTV at the program level (rather than at the gym-wide level) is where some uncomfortable truths surface. Three patterns are common:

Kids’ programs are usually higher-margin than adult programs, even though they appear to be priced lower. The reasons: parents tend to attend and add their own membership; siblings join; kids tend to stay longer than adults (they don’t move for jobs, they don’t get injured at the same rate, they don’t develop training fatigue as fast). When you compute the family-LTV impact of a kids’ student rather than the per-student tuition, the kids’ program often produces 1.5-2x the LTV of an adult-only member. Most gym owners don’t see this because they look at per-student dues. They make pricing and program decisions that way and end up under-investing in the program that actually drives the gym’s economics.

No-gi-only memberships have the worst LTV of any tier. No-gi-only members tend to be specialists who train selectively, attend less consistently than gi members, and have the highest churn rate of any segment. The per-member pricing is often the same as gi-only or unlimited, but the LTV difference can be 30-40%. This argues either for pricing no-gi-only at a premium (since the margin is worse) or for restructuring to push members toward unlimited tiers.

Drop-in and class-pack members are LTV-positive even at low absolute revenue. Drop-ins look unattractive on a per-visit basis, but they include the population of “I’m not sure if I’m going to commit yet” members, a meaningful percentage of whom convert to monthly recurring after enough drop-in usage. The drop-in revenue itself is mostly noise; the conversion path is the real value. Gyms that don’t measure conversion from drop-ins to monthly often underprice or overprice drop-ins because they don’t know which they’re optimizing for.

These patterns aren’t universal — every gym has its own data — but the broader lesson is that program-level decisions made without LTV are usually wrong in some specific way that compounds over years.

The CAC-LTV ratio: the single most important number

If you only run one piece of math, run this one. Customer Acquisition Cost divided by Lifetime Value, or its inverse (LTV / CAC ratio).

A healthy LTV/CAC ratio for a recurring-revenue business is around 3:1 — that is, for every dollar you spend acquiring a member, the member produces three dollars of lifetime value. Below 3:1, you’re acquiring expensively relative to value; above 5:1, you’re probably under-investing in growth and could afford to acquire more aggressively.

Most BJJ gyms run at extreme ratios, in both directions:

Some gyms run 30:1 or higher. Their CAC is essentially zero (all word-of-mouth), and their LTV is moderate. The math says they could spend significantly more on acquisition and still come out ahead. They don’t because the spend feels uncomfortable.

Some gyms run 1:1 or worse. They spend on lead generation but their LTV is low (because of pricing or retention problems), and the spend isn’t recouped. They don’t realize they’re underwater because they’re not measuring.

The corrective conversation is the same in both cases: figure out the LTV first, figure out the CAC second, and let the ratio tell you whether the current allocation is right. Without the math, the conversation about acquisition spending is purely emotional.

What good gyms target

A few benchmarks worth carrying around for a well-run BJJ gym:

• LTV per adult member: $2,500-$5,000+ depending on pricing tier and program structure.
• Average tenure: 18-30 months. The 30-month figure is achievable with strong retention systems.
• CAC: $50-$300 per member. The lower end is mostly word-of-mouth driven; the higher end uses some paid channels.
• LTV/CAC: 3:1 to 8:1. Below 3:1 is expensive growth; above 8:1 is missed growth opportunity.
• Annual gross margin: 55-70%. Anything below 50% means costs (rent, coach pay, equipment) are too high relative to revenue.
• Family LTV multiplier: 1.5-2.5x the per-person LTV when accounting for sibling and parent enrollment effects.

These ranges aren’t prescriptive — every market and gym is different — but they’re useful as sanity checks. If your LTV is below $1,500, something is probably broken in pricing, retention, or both. If your CAC is above $500, your acquisition channels probably aren’t sustainable.

Why most gyms don’t run this

Honest answer: it requires data the typical fragmented gym setup doesn’t produce. Computing LTV requires linking membership history, payment history, retention duration, and add-on purchases for each member. Most gyms can’t do this because the data lives in different systems and reconciling it is too painful to do regularly.

This is one of the practical arguments for consolidated gym software (covered separately): not because the software computes LTV for you (though it does), but because the underlying data structure makes the question answerable in 30 seconds instead of 30 hours. Most gyms that move from fragmented to consolidated tooling discover their real LTV for the first time within the first month. The number is almost always different from what they expected, and the resulting strategic conversations are different.

FAQ

What’s the difference between gross LTV and net LTV?

Gross LTV is total revenue per member over their tenure. Net LTV applies gross margin (typically 55-70% for BJJ gyms after coach pay, rent share, equipment, etc.) and reflects what the member actually contributes to the business. Use net LTV for acquisition decisions; use gross LTV for revenue planning.

Should I include event revenue in LTV?

Yes, if events are a recurring monetized program. Spread the per-member event revenue across the year. If your events are pure community-building with zero revenue, they don’t go in LTV directly but do contribute indirectly through retention.

What’s a reasonable target tenure?

Industry-wide fitness tenure averages around 12-15 months. BJJ runs higher because of the multi-year skill arc — 18-24 months is normal, 24-30+ is well-run. Below 12 months suggests retention problems.

Does this apply to kids’ programs?

Yes, but compute family LTV (total revenue from the household) rather than per-student LTV. Kids’ programs often look unprofitable per-student but very profitable per-family.

How often should I recompute?

Quarterly. The numbers shift gradually with pricing changes, program changes, and market conditions. Annual recomputation is the minimum.
