Poker odds calculator: who is ahead, and by how much
Updated November 2026
Pick your two cards, his two cards and as much of the board as you know. The calculator shows how often each hand wins if the cards are played out to the river with no more betting.
The rules of thumb
What does the percentage mean?
It's your equity: your share of the pot if nobody bets again and the remaining cards are simply dealt. A 60% hand gets the whole pot six times out of ten. Tied boards are counted as half a win each.
It doesn't tell you whether to bet or call. For that you compare it with the price, which is what pot odds are for.

Over many hands, that's what your share is worth.
How accurate is it?
From the flop on, it goes through every remaining card, so the answer is exact. On the turn that's 44 possible rivers, and on the flop it's 990 possible turn and river pairs.
Before the flop it deals 100,000 random boards. That keeps the result within about a third of a point. Leave his hand empty and he gets a random one on every deal.
Boards it checks
Which matchups come up all the time?
A handful of shapes cover most all-ins before the flop. These are counted across every possible board.
Common matchups before the flop
First hand wins, ties, loses
The one that surprises people is a small pair against two higher cards. Two ace-high cards look much stronger, but the pair is ahead until they hit, and they hit less often than it feels.
How much does the flop change things?
A lot. These are worked out on this page when it loads, across every turn and river.
Do suits change the odds?
What does "dominated" mean?
A hand is dominated when it shares a card with a better hand. Ace-queen against ace-king is the classic case: when an ace comes both hands pair it, and the king still wins.
That's why ace-queen wins only about 1 time in 4 there, even though it looks strong. If a queen comes it's ahead, and if an ace or a king comes it isn't.
What is a race?
A race is a matchup close to even, usually a pair against two higher cards. The pair is ahead now, and the two higher cards have six outs and five cards to hit them.
A pair of twos beats ace-king a shade more than half the time. Eights do it 55 times in 100. In a tournament you'll play dozens of these, and over time they come out about even.

Why does 80% still lose so often?
Because 80% means losing 1 time in 5. Aces against kings are about as good as it gets before the flop, and they still lose 18 times in 100. If you see it happen twice in one night, nothing's wrong with the deck.

How strong is each kind of draw?
Here are four draws against a pair of queens on the same flop of 9-8-2, with two hearts on it. These are exact, counted across every possible turn and river.

Exact, with two cards to come
How do you use the number at the table?
You compare it with the price of the call. Say he bets half the pot and you need 25%. If the calculator says your hand has 35% against what you think he holds, the call makes money.
The hard part is the phrase "what you think he holds". Nobody shows you their cards in real life, so you need to estimate a whole group of hands. That's a range.
Equity against the price
What about more than two players?
Every extra hand takes a share. Pocket aces win 85 times in 100 against one random hand and 34 in 100 against eight. That's still three times a fair share, and it shows why even the best start in poker can't be sure of anything at a full table.

What can't an odds calculator tell you?
- What he really hasYou have to supply his hand, and at the table you only ever know a range.
- What the betting will doEquity assumes every card gets dealt. In real hands someone may fold first.
- How much you'll winBeing ahead in a small pot is worth less than being a bit behind in a big one.

Questions players ask about poker odds
What does "60/40" mean?
One hand wins six times in ten and the other four, more or less.
What is a coin flip in poker?
Two hands close to even, usually a pair against two higher cards.
Is this the same as pot odds?
No. This shows your chance of winning. Pot odds show the price you're being offered.
Does suit matter?
Yes, a little. Flushes change the numbers, so two suited hands that share a suit will come out differently from two that don't.
Can I use this while playing online?
Site rules differ, and many ban tools during a hand. Use it to study between sessions.
Why are the numbers slightly different from other calculators?
Before the flop this page deals 100,000 random boards, so it can move by a third of a point. From the flop on it's exact.
Can I work out odds in my head?
For draws, yes: multiply your outs by 2 with one card to come and by 4 with two.
How the numbers on this page were worked out
All the math runs in your browser. Each seven-card hand gets a score, and the two scores are compared. Ties count as half a win. The matchup chart and the rules of thumb come from going through all 1,712,304 possible boards for each pair of hands.
