Belt Promotion Timeline Estimator
See a realistic time-to-next-belt range from your current belt and how often you train. The minimums are anchored to IBJJF time-in-grade rules; the rest is an honest estimate, because promotion is your coach’s call.
Black-belt review pendingWhat the numbers are based on
IBJJF sets minimum time-in-grade requirements at the upper belts: roughly two years at blue before purple, eighteen months at purple before brown, and one year at brown before black, with no fixed minimum from white to blue. Those minimums are real rules. Everything beyond them — how long it actually takes — depends on mat time, consistency, competition, athleticism and your instructor’s standards.
This estimator combines the minimums with typical progression rates by training frequency to give a range. Train more often and you trend toward the faster end; train twice a week and it stretches out.
The belt is given, not earned by a clock
No calculator promotes you. Your coach does, when your jiu-jitsu earns it. Use this to set expectations and stay patient, not to argue for a stripe. The grapplers who progress fastest are usually the ones who stopped counting and just kept showing up.
| Promotion | Minimum time at current belt |
|---|---|
| White → Blue | No fixed minimum |
| Blue → Purple | 2 years |
| Purple → Brown | 1.5 years |
| Brown → Black | 1 year |
