Pot odds
The pot is 100 and the opponent bets 50. You call 50 to win 200 (3 to 1): you need 25.0% equity for the call not to lose chips, if there is no more betting afterwards.

One Calculator, the same validated math at every level. Higher level = more tools and more depth, always easy to use. Every result says what it means and shows the step-by-step math.
Try every Upper Intermediate tool on 20 real hands, with the same engines as the paid version. No card needed.
What a hand is: a situation you analyze. It starts when you tap “Start hand” and lasts until you start the next one or 20 minutes. Within the hand you use EVERY tool and change cards and numbers as often as you like. Opening the page, reloading, switching tools or opening another tab does not use up hands.

Worked examples
Outs
With 9 outs on the flop (a flush draw), you hit on the turn 19.1% of the time, and by the river 35.0%. The rule of 4 gives 36%: handy for doing the math in your head.
Equity
vs before the flop: 46.2% vs 53.8%. Exact calculation over all 1,712,304 possible boards.
Combos
AK has 16 combos (4 suited and 12 offsuit). If you hold the ace of hearts, the opponent can only have 12: your card blocks the rest.
