Poker odds calculator
Put two or more hands on a board and see who is ahead, by how much, and whether the price you are being offered justifies the call. Exact when the runouts can be counted, and honest about it when they cannot.
Hands
Nothing leaves your browser.
Leave empty for preflop. Three, four or five cards.
Equity
40,000 simulated runouts.

Pot odds
The price the pot is offering you.
You are getting 2 : 1. The call breaks even at 33.3% equity.
Your 81.1% clears that price by 47.8 points, before anything either of you does on later streets.
Equity and pot odds are two halves of one question
Equity is how often you win. Pot odds are what you are being charged to find out. A call is profitable when the first number is bigger than the second, and almost every bad call in poker is a hand with real equity being paid at a price that equity does not cover.
The arithmetic is small. Calling 50 into a pot of 100 puts 50 in to win 150, so the call needs 33.3% equity to break even. A flush draw on the flop has roughly 35% to get there by the river. That is why the draw is a call at that price and a fold at a much larger one, and why the size of the bet matters more than the strength of the draw.
What this calculator will not tell you
It compares known hands. At a real table you do not know your opponent's cards, you know roughly what they would play that way, and the gap between those two things is most of poker. Equity against a single hand is a useful floor, not the answer.
It also stops at this street. Implied odds, the money you win on later streets when you hit, can turn a call that is short of its price into a clear one. Reverse implied odds do the opposite. Neither is arithmetic, both are judgement.
Where the numbers come from
The hand evaluator here is the same one that prices decisions inside a session debrief. There is no second implementation and no model involved, so a number on this page and a number in a report cannot disagree.
Common questions
Is this poker odds calculator free?
Yes, entirely, with no account and no limit on how many hands you run. It is written in TypeScript and executes in your browser, so it costs nothing to serve and your hands never reach a server.
Is the equity exact or simulated?
Both, and the page always says which. When the remaining board can be enumerated outright, every runout is counted and the answer is exact. Preflop the number of runouts is too large, so it runs a seeded simulation and reports the trial count. The seed is derived from the cards, so the same question always returns the same answer.
What equity does my hand need to call?
Exactly the pot odds percentage. Calling 50 into a pot of 100 means putting in 50 to win 150, so the call breaks even at 33.3% equity. Anything above that is profitable on this street alone, before implied odds.
Does it handle multiway pots?
Yes, up to six hands at once, and equity is split correctly on ties. Multiway equity is where most players are furthest off: a hand that is a clear favourite heads-up is often a clear underdog against three opponents.
Can I use this while I am playing?
No, and you should not. Real-time assistance breaks the rules of every poker room and can cost you your account and your balance. This calculator is for studying hands you have already played, or spots you are working through away from the table.
Your session, debriefed
These calculators answer one spot. A debrief reads the whole session: the hands that decided it, reviewed street by street, and your leaks priced in big blinds. The first one is free and complete, not a preview.
No card. No subscription. $3 a session after that, and credits never expire.
