You’ve probably heard the famous stat: only 1 in 10 white belts earn their blue belt. Rener Gracie says it. Every “should I quit BJJ” thread repeats it.

And the folklore gets more depressing from there: supposedly, only 5% of blue belts ever make purple.

I’ve never seen a rigorous source for these numbers. As far as I can tell, there isn’t one.

But now, I have one.

Since February 2022, I’ve taught the intro class at my gym to every new student who walked through the door: 68 people total.

I wrote down all of their names. I know who’s still training, who got promoted, and who dropped out.

This post is what that data actually says.

Spoiler: My gym’s numbers look nothing like the folklore.

BJJ Retention Data: At a Glance

Scope	One instructor at one BJJ gym
Beginners logged	68 students
Students reliably tracked	54 students
Mature cohort	32 students who started before 2025
Earned blue belt	12 of 32 — 37.5%
Blue belts who earned purple	4 of 12 — 33.3%
Still training today	6 of 32 — 18.8% of the mature cohort
Researcher	Tsavo Neal, BJJ Equipment

12 Key BJJ Statistics (From My Gym)

1. More than 1 in 3 white belts at my gym earned their blue belt (37.5%) — nearly 4x the famous “1 in 10” claim
2. 1 in 3 blue belts went on to earn purple (33.3%) — folklore says 5%
3. 12.5% of the mature cohort eventually reached purple belt — folklore math implies ~0.5% of white belts get their purple
4. 18.8% of the mature cohort are still training today — about 4 in 5 students are no longer training in our gym
5. Most people quit in months 3–18 of white belt — NOT at blue belt. The “blue belt blues” is real, but it’s not where most people quit
6. The attrition curve: 86% of this year’s students are still training, 33% of last year’s are still training, and 19% of the pre-2025 cohort are still training — quitting is front-loaded, then slows to a drip
7. Blue belts split roughly into thirds: a third earned purple, a third quit, and a third are still training at blue — 9 of our 13 blue belts earned purple, still train at blue, or left because they moved
8. Each purple belt “cost” about 14 intro students — folklore math would imply about 200 intro students for one purple belt, or about 800 for four
9. None of the 7 women currently train at our gym, versus 36% of men — though two of those women made it to 4 stripes before either leaving or moving away
10. Both students who left with 4 stripes on their white belt — one promotion from blue — were women; one quit, one moved cities
11. Typical time to blue belt at my gym: 1.5 to 2+ years — with a few exceptions for those who had prior grappling experience OR who trained 4 times per week consistently and/or competed
12. 3 of 54 students left because they moved, not because they quit — a distinction I haven’t seen retention stats make

The Numbers

I analyzed 54 students: everyone I taught at our Burnaby location from November 2022 to now, plus two students who started at our old Vancouver location and continued training in Burnaby after it closed. (More on the exclusions in the methodology section.)

The headline: BJJ promotion rates

Of the 32 students who started before 2025 — the ones who’ve had enough time on the mats for the data to mean something — 12 earned their blue belt. That’s 37.5%, or more than 1 in 3.

It gets better. Of those 12 blue belts, 4 went on to earn their purple belt: 33.3%. The folklore number is 3-5% of blue belts go on to earn their purple. Even with a small sample size, that’s not a rounding error. This one I’m particularly proud of.

Put another way: 12.5% of the white belts I taught the intro class to before 2025 are now purple belts. If the folklore rates were true, that number should be around 0.5%.

The honest number: 18.8% are still training today

Here’s the stat that keeps this post from being a humblebrag. Of those same 32 students who started before 2025, only 6 are still training today. That’s 18.8% of the mature cohort still training as of July 2026. Roughly 4 out of 5 people who took my intro class eventually quit.

For perspective: the folklore says only 10% of white belts even reach blue belt. Nearly twice that share of our students are still on the mats today. Not just promoted once, but actively training years later.

If I’d just counted everyone currently active across all 54 students, I could have claimed 31.5% retention. But that number is inflated by recent students who haven’t had time to quit yet.

Here’s what happens when you split students by start date:

Cohort	Started	Still training
2026 starts (n=7)	This year	86%
2025 starts (n=15)	6–18 months ago	33%
Pre-2025 starts (n=32)	18 months – 4.5 years ago	19%

Recent students have had less time to quit, so combining every cohort inflates the apparent long-term retention rate. It’s also the most useful chart in this post, because it shows you when people quit.

The killing field is white belt, not blue belt

Look at that curve again: 86% → 33% → 19%. Most of the drop happens between a few months in and the 18-month mark — deep in white belt territory, usually before anyone gets close to a promotion.

Meanwhile, the blue belts? Of the 13 students who earned blue (across all cohorts), only 4 quit the sport. Two more moved away at blue belt. If I’d counted movers as quitters, my blue belt quit rate would jump from 31% to 46%. 9 of our 13 blue belts either earned purple, still train at blue, or left because they moved.

Everyone talks about the “blue belt blues.” My data says blue belt isn’t where people leave. It’s where they are likely to become BJJ practitioners for a long time.

The dangerous stretch is the long, unglamorous middle of white belt: after the initial novelty wears off and before the first belt promotion.

If you make it to blue at our gym, it’s more likely than not you’ll stick around (unless you move away).

A few smaller things the data showed:

• Each purple belt “cost” about 14 intro students. Four purples came from 54 tracked students. At the commonly repeated folklore rates, producing one purple belt would require about 200 intro students — or roughly 800 for four.
• “No longer trains here” is not the same as “quit.” Three of our students moved away: two at blue belt, one at 4 stripes. And one blue belt stopped training when he had a kid. Most retention stats you’ll see don’t separate life circumstances from disillusionment, which overstates how many people actually give up on jiu-jitsu.
• Two students left at 4 stripes — the doorstep of blue belt. Both were women; one quit, one moved. I don’t know what to make of that yet, but leaving one promotion away from the thing everyone supposedly quits after is its own phenomenon.
• The fastest blue belt in my dataset was a former wrestler with 20 years of mat time — he got his blue belt in about 6 months (and quit). Everyone else took ~1.5–2 years.
• One student in the data started the day before I started writing this. His retention record is 1 day. I’ll report back on this one.

The women’s numbers

7 of our 54 students were women — 13.5%. None currently train at our gym. Men’s retention over the same period: 36%.

Before anyone draws big conclusions: it’s a sample of seven, and the details matter. Two of those seven made it all the way to 4 stripes, and one of them left because she moved cities, not because she quit.

But I’ll say more about this in the observations below, because I think there’s something real here about cold-start problems.

The Methodology

This is one instructor’s complete log at one gym. Here’s exactly how I counted:

• The full count: I’ve taught 68 intro students total: 16 in Vancouver (February 2022-October 2022, before that location closed) and 52 in Burnaby (November 2022–July 2026). Two of the Vancouver students continued at Burnaby after the closure, so they’re included — the other 14 are excluded because I can’t verify their training status. Total analyzed: 54.
• Cohorts: “Matured” means started before 2025: at least 18 months of runway, enough time to quit, get promoted, or prove they’re in it for good. The 2025 and 2026 cohorts are reported separately because their stories aren’t finished. When I cite promotion rates, I use the matured cohort only; counting a student who started three months ago as “didn’t get their blue belt” doesn’t make sense.
• Moved vs. quit: If a student left because they moved cities, I count them as “no longer training here,” not as a quit. There were three: two at blue belt, one at four stripes.
• What this data can’t tell you: Whether my gym is typical. It’s one gym, one intro program, one head coach’s curriculum. That’s precisely why I’m publishing it. I’d love to see other instructors’ numbers. More on that at the end.

How Our BJJ Intro Class Works

Some context on the class this data comes from, because I think it’s relevant to the results.

Our gym runs a private 45-minute intro class before new students join regular classes.

I’ve taught it since I was a blue belt. I taught my first one on February 7th, 2022. The curriculum comes from Ritchie, our head coach.

Every new student learns:

1. How to tie their belt
2. Technical stand up
3. Shrimping
4. Bridging
5. Forward and backward rolls
6. Armbar from closed guard
7. Whatever we will cover in the main class
8. An open question period at the end

Before I teach the armbar, I tell them I’m going to apply it very slowly, and that they should tap and I’ll immediately let go. It sounds like a small thing, but it’s not. For a lot of people, that’s the moment they learn this sport has a safety valve. It also establishes clear expectations around safety and taking care of each other as we roll.

To be clear about my role: the only thing I do at this gym is teach the intro class. I’m not involved in billing, communication, lead generation, or retention follow-up. It’s a volunteer position (I do get free membership), and honestly, I feel privileged to teach it. I try my best to make every new student feel welcomed, safe, and comfortable. And I make a point of partnering with them during the instruction portion of class for their first few weeks.

One more variable worth disclosing: our pricing is $227/month. I don’t track what other programs charge, so I can’t tell you where that sits. But pricing surely affects retention, so I’m mentioning it here.

What I’ve Observed That the Numbers Can’t Show

I cannot predict who will stay. The young wrestler who comes in, crushes everyone from day one, and lives five minutes from the gym? Gone in 6 months. The retired tech guy in his mid-50s? Still training after 3 years. After 68 students, I have given up trying to guess.

The one signal I’ve found: friends. If someone trains with a friend, or makes real friends at the gym quickly, their odds go way up. The social factor seems to matter more than athleticism, age, proximity, or how much they love jiu-jitsu in month one. People quit hobbies. They’re less likely to quit their tribe.

The women’s cold-start problem is real. Women hardly join, and when they do, they’re harder to retain. I think those two facts feed each other. If a woman walks into a gym with zero other women training, she’s being asked to do something harder than what every male student is doing. The gyms I’ve seen with strong female membership got there because a critical mass formed, and a critical mass can’t form one isolated student at a time.

Bad first experiences are everywhere, and they’re avoidable. I’ve lost count of the students who came to us after a trial class at another gym went badly. Getting roughed up on day one. Zero introduction. Zero structure. Just thrown into a regular class (with another newbie) to sink. Nobody speaking to them.

When I put on my business hat, this is the most obvious onboarding failure imaginable. No other membership business would survive treating new customers this way, and yet in BJJ it seems quite common.

Like anything else, “what gets measured gets managed.” If you’re a gym owner, I’d start by tracking attendance and following up with new students. MatGoat makes it easy for gym owners to track attendance, send follow up messages, and much more.

Is Our Gym an Outlier, or Are the Gracie Stats Wrong?

Here’s my honest take: I think retention is influenceable, and I think having a private comprehensive intro class is the biggest lever a gym controls.

A structured intro class — where a new student learns the basics safely, gets an actual welcome, and taps on their first armbar knowing they’re safe — doesn’t cost much.

My gym’s numbers suggest it might triple your blue belt rate. Or my gym might just have the greatest head coach ever (shout out to you, Ritchie). With one gym’s data, I can’t tell you which.

That’s where you come in.

If you’re an instructor or gym owner who tracks your students — even informally — I’d love to see your numbers.

• How many of your white belts made blue?
• How many blues made purple?
• What percentage of your blue belts quit?

And if you’re a white belt somewhere in that months-3-to-18 valley right now, wondering if you’re the only one struggling: statistically, this is exactly when everyone struggles.

The data says if you survive this stretch, you’ll be in for a while. Maybe even for life.

Every stat in this post comes from my own log of every intro student I’ve taught. If you cite these numbers, please link back here so people can check the methodology and so I can update this post as the dataset grows.

Happy rolling. 🤙
