Turn a session or a sample into bb/100, dollars per hour and total profit — the real measure of how you're beating the game. Instant, in your browser.
bb/100 — big blinds won per 100 hands — is the standard way to measure a cash-game win rate, because it's independent of stake and of how fast you play. A solid online winner runs around 2–5 bb/100; live players, facing weaker fields but far fewer hands per hour, often post more. One caveat: a win rate only becomes trustworthy over a large sample — tens of thousands of hands — so treat a hot week as noise, not proof.
'I'm up money' means nothing without stakes and volume. bb/100 turns your results into an edge you can actually compare and track.
You can't compare 'I won $300' at one table to '$300' at another until you know the stakes and how many hands it took. Big blinds won per 100 hands strips both out: it measures how much you beat the game for, regardless of limit or speed. That's why every tracker and every coach talks in bb/100 — it's the one number that lets a 2NL grinder and a high-stakes reg compare edges on the same scale.
A win rate from a few thousand hands is mostly noise — variance can show a losing player a big profit and a winner a downswing over that span. It takes tens of thousands of hands before bb/100 settles near your true edge. Use this tool to track the trend, pair it with the variance simulator to see the swings around it, and never quit or move up on a week's results alone.
Enter your result and volume, read your bb/100 and hourly.
Put in how many big blinds you won (a loss is negative), the number of hands, and the hours if you want an hourly figure.
Enter the big blind in dollars for your stake — $1 for $0.50/$1.00 — to convert big blinds into money.
You get bb/100, plus dollars per hour, per 100 hands, and total profit — the full picture of how you're running.
Say you're up 250 big blinds over 5,000 hands. Your win rate is (250 / 5000) × 100 = 5 bb/100 — a strong, clearly winning number. If your big blind was $1 and it took 20 hours, that's $250 profit, or $12.50 an hour. So far so good — but 5,000 hands is a tiny sample. A run that good over that few hands is well within the range of normal variance even for a break-even player, so read 5 bb/100 here as an encouraging hint about your edge, not proof of it. Keep playing and watch whether the number holds as the sample grows into the tens of thousands.
Verdict — a strong-looking 5 bb/100, but over just 5,000 hands treat it as a hint, not proofFix Over that span variance swamps skill — a losing player can show a fat profit and a winner a downswing. Wait for tens of thousands of hands before you trust the number.
Fix "I made $300" at $0.50/$1 and at $2/$5 mean completely different things. bb/100 strips out the stake so the comparison is actually fair.
Fix The house takes a cut of most pots, and at small stakes it eats a big chunk of your edge. Your tracked bb/100 is already after rake — don't expect the pre-rake number.
Fix A hot week isn't a raise in your true win rate. Move up on a large, proven sample and a healthy bankroll, not on a few thousand lucky hands.
Three quick checks. Decide, then see the math.
You won 100 big blinds over 2,000 hands. What's your win rate in bb/100?
bb/100 = (big blinds won ÷ hands) × 100 = (100 / 2000) × 100 = 5 bb/100. It's the standard unit because it's independent of stake and game speed.
What counts as a good win rate in online cash games?
Roughly 2–5 bb/100 is a solid, sustainable online cash win rate, and above 5 is strong. Rates like 20–30 bb/100 only survive over tiny, lucky samples.
How many hands do you really need before a win rate is trustworthy?
It takes tens of thousands of hands — often 50,000+ — before variance settles and bb/100 converges toward your true edge. Anything smaller is mostly noise.
You scored 0 / 3. The more you drill this, the faster the maths becomes instinct.
For online cash games, roughly 2–5 bb/100 is a solid, sustainable winning rate, and anything above 5 is strong. Live players often show higher bb/100 against weaker fields, but play far fewer hands per hour, so their hourly rate can be lower.
Big blinds won per 100 hands. It's the standard win-rate unit because it's independent of stake and of how fast the game runs, so it lets players at different limits compare their edge directly.
Divide your winnings in big blinds by the number of hands played, then multiply by 100. Win 250 big blinds over 5,000 hands and your win rate is (250 / 5000) × 100 = 5 bb/100.
Tens of thousands. Over a few thousand hands, variance dominates and the number is unreliable. Only across large samples — often 50,000+ hands — does bb/100 converge toward your real edge.
Both. bb/100 measures how well you beat the game; dollars per hour measures what your time is worth. Live players lean on hourly, online players on bb/100 — this tool shows you both at once.
