Pot odds calculator
Pot odds tell you the share of the time a call has to win to break even. Enter the pot before your call and the amount you have to put in.
Everything in the middle, including the bet you face.
- Equity needed to break even
- 33.3%
- Pot odds
- 2 : 1
- Pot you are playing for
- 90
- Pot before the call, plus your call.
required equity = call / (pot + call)
This is the break-even point for the current street only. Implied odds, position and future streets can justify a call below it, and reverse implied odds can make a call above it wrong.
How to calculate pot odds in poker
Pot odds compare the price of a call with what the call can win. Four steps take you from the table to a number:
- Add up the pot as it stands when the action reaches you, including your opponent’s bet.
- Note the amount you have to put in to call.
- Divide the call by the pot after your call: the pot plus the call. That is the equity you need.
- Compare it with your hand’s equity against the hands that bet. If yours is higher, the call makes money on this street.
Say the pot is 40 and your opponent bets 20. The pot before your call is 60, you call 20 and you play for 80, so you need 20 / 80 = 25.0%. A half-pot bet always asks for 25.0%, whatever the stakes.

The same spot written as odds is 3 : 1 — the pot offers 3 times your call. To turn odds into a percentage, divide 1 by the odds plus one: 1 / (3 + 1) = 25.0%. The calculator shows both, because players quote both.
Pot odds for common bet sizes
The equity a call needs depends only on the size of the bet relative to the pot, so one table covers every stake. Bigger bets ask for more:
| Bet (share of the pot) | You call | Pot odds | Equity needed |
|---|---|---|---|
| 25% | 25 | 5 : 1 | 16.7% |
| 33% | 33 | 4.03 : 1 | 19.9% |
| 50% | 50 | 3 : 1 | 25.0% |
| 66% | 66 | 2.52 : 1 | 28.4% |
| 75% | 75 | 2.33 : 1 | 30.0% |
| 100% | 100 | 2 : 1 | 33.3% |
| 150% | 150 | 1.67 : 1 | 37.5% |
| 200% | 200 | 1.5 : 1 | 40.0% |
From outs to equity
Pot odds answer half the question: what the call costs. The other half is how often you win, and with a draw that comes down to outs — the unseen cards that complete your hand. On the flop you see five cards, so 47 are unseen; on the turn, 46.
| Draw | Outs | Next card only | Turn and river |
|---|---|---|---|
| Gutshot straight draw | 4 | 8.7% | 16.5% |
| Two overcards | 6 | 13.0% | 24.1% |
| Open-ended straight draw | 8 | 17.4% | 31.5% |
| Flush draw | 9 | 19.6% | 35.0% |
| Flush draw and gutshot | 12 | 26.1% | 45.0% |
| Flush draw and open-ender | 15 | 32.6% | 54.1% |
Pot odds practice: three spots
Work each one out before reading the answer. All three use the method above and the outs table.
- Turn. You hold a flush draw. The pot is 100 and your opponent bets 50. You call 50 to play for 200, so you need 25.0%. Nine outs with one card to come give 19.6%. You are short by 5.4 points, so the call loses money unless you win more on the river.
- Flop. You hold an open-ended straight draw and face a bet of 33 into 100, with stacks behind. You need 19.9%; eight outs to see the turn give 17.4%. It is close: winning about 24 more when you hit makes the call break even.
- Flop. You hold a flush draw and an open-ender, and your opponent moves all-in for the size of the pot, 100 into 100. You need 33.3%; fifteen outs over two cards give 54.1% against a made hand that is not drawing to beat you. Call — you are the favourite.
Pot odds vs implied odds
Pot odds price a call using only the money already in the pot. Implied odds add what you expect to win on later streets when the draw comes in. They are why the second practice spot can be a call even though the immediate price is wrong — but only if your opponent will actually pay you off, and only by the amount they will pay.
Reverse implied odds work the other way. A draw that can complete and still lose — a low flush on a board where a higher one is possible, or a one-card straight on a paired board — costs you more on the hands where you hit and are beaten. Those draws need a better price than the table suggests.
- Out of position you will not always see the river for the price of one call, so discount your equity.
- In a multiway pot, count only the outs that are likely to win against every player left.
- In tournaments, the chips you risk are not worth their face value. Check close calls with the ICM calculator.

Questions about this calculator
- What are pot odds in poker?
- Pot odds compare what you must call to the pot you would win. Expressed as equity, they give the minimum share of the time your hand has to win for the call to break even.
- Do pot odds include my own call in the pot?
- Yes. The pot you are playing for is the pot before your call plus the call itself, which is why calling 30 with 60 in the middle needs 33.3% rather than 50.0%.
- How do I convert pot odds into a percentage?
- Divide 1 by the odds plus one. 3 : 1 means 25.0%, and 2 : 1 means 33.3%. The calculator shows both forms side by side.
- Is a call with exactly the required equity worth making?
- At exactly break-even the call is neutral in chips. Position, implied odds and how often you can realise your equity decide it from there.
- What is the rule of 2 and 4?
- A shortcut for draws: multiply your outs by 2 for one card to come and by 4 for two. It is close for small draws and too generous for big ones — fifteen outs times four is 60%, against an exact 54.1%.
- Do pot odds work the same way in tournaments?
- The arithmetic is identical, but chips you lose are worth more than chips you win once the payouts matter. Near the bubble or at a final table, a call that is fine by pot odds can still cost money.
