What is bb/100?
bb/100 is big blinds won per 100 hands. Because it is measured in big blinds, it lets you compare win rates across stakes: 5 bb/100 at NL10 and 5 bb/100 at NL200 mean the same edge.
bb/100 = (profit ÷ big blind) ÷ hands × 100
Example: $600 profit at NL100 ($1 big blind) over 12,000 hands = 600 bb ÷ 12,000 × 100 = 5 bb/100.
What is a good win rate?
| Win rate | Online | Live (bb/hour) |
|---|---|---|
| Small winner | 0–2 bb/100 | 0–2 bb/hr |
| Solid winner | 3–5 bb/100 | 3–5 bb/hr |
| Strong winner | 5–10 bb/100 | 5–10 bb/hr |
Sample size
Win rates are noisy. With a typical standard deviation of 80–100 bb/100, even 50,000 hands leaves your measured win rate several bb/100 away from your true one. The calculator shows a rough 95% range for your sample. See variance in poker.
FAQ
Should I use bb/100 or $/hour?
Online, bb/100 is standard. Live, where you see far fewer hands, bb/hour and $/hour are more practical. The free poker tracker shows your hourly rate automatically.
Does rakeback count?
Track it separately so you know your win rate from play alone.
