Poker Pot Odds Calculator
Enter the pot and the bet you are facing to see the equity you need to call. Add your outs to check whether your draw has the odds.
Your hand (optional): check if you have the odds
One-card direct odds assume you fold after a miss and pay no further bets. Use by-the-river odds when this call guarantees both cards, such as an all-in or a guaranteed free river.
Add your outs on the left to see whether you have the odds to call.
How pot odds work
Pot odds are the price of a call. If the pot is 100 and someone bets 50, you must call 50 to win the 150 already out there, so you are getting 3-to-1. Turn that into a percentage and you need to win at least 25.0% of the time for the call to break even.
Compare that required number to your equity, which is how often your hand actually wins. If your equity is higher than the price, calling makes money over time. The calculator above does both steps: it gives the equity you need, then checks it against your draw.
Pot odds by bet size
| Bet size | Equity needed | Pot odds |
|---|---|---|
| 1/3 pot | 20.0% | 4 : 1 |
| 1/2 pot | 25.0% | 3 : 1 |
| 2/3 pot | 28.6% | 2.5 : 1 |
| 3/4 pot | 30.0% | 2.3 : 1 |
| Pot | 33.3% | 2 : 1 |
| 1.5x pot (overbet) | 37.5% | 1.7 : 1 |
| 2x pot | 40.0% | 1.5 : 1 |
Bigger bets demand more equity. That is why a draw can call a small bet but should fold to an overbet.
Draw odds: the next card, the river, and the rule of 2
| Draw | Outs | Next card (flop) | × 2 | By the river, both cards guaranteed | × 4 | Next card (turn) | × 2 |
|---|---|---|---|---|---|---|---|
| Flush draw | 9 | 19.1% | 18% | 35.0% | 36% | 19.6% | 18% |
| Open-ended straight draw | 8 | 17.0% | 16% | 31.5% | 32% | 17.4% | 16% |
| Gutshot | 4 | 8.5% | 8% | 16.5% | 16% | 8.7% | 8% |
| Combo draw | 15 | 31.9% | 30% | 54.1% | 60% | 32.6% | 30% |
| Two overcards | 6 | 12.8% | 12% | 24.1% | 24% | 13.0% | 12% |
| Set draw | 2 | 4.3% | 4% | 8.4% | 8% | 4.3% | 4% |
For one-card direct odds, use the next-card columns: your outs divided by the 47 unseen cards on the flop or the 46 on the turn. The by-the-river column is the chance at least one out arrives on the turn or the river, and prices a call that guarantees both cards. Outs × 2 per card is the estimate to use at the table; it stays within two points up to about ten outs and comes in a little low on bigger draws.

Frequently asked questions
What are pot odds in poker? +
Pot odds are the price you are being offered to call a bet, expressed as the ratio of the amount you must call to the total pot you would win. They tell you the minimum equity your hand needs for calling to break even.
How do you calculate pot odds? +
Divide the amount you must call by the total pot after your call. If the pot is 100 and your opponent bets 50, you call 50 to win 150, so you need 50 / 200 = 25.0% equity. As a ratio that is 3-to-1.
What pot odds do I need for a flush draw? +
A flush draw has 9 outs. If you plan to fold after a miss and pay no further bets, price the next card, and the turn completes your flush 9 times in 47, 19.1%. That is short of the 25.0% a half-pot bet asks for, so on direct odds alone a flush draw can call only about a third of the pot, and bigger calls lean on implied odds. The 35.0% chance of hitting by the river applies when this call guarantees both cards, and then it beats even the 33.3% a pot-sized bet needs.
What is the difference between pot odds and equity? +
Pot odds are the price of the call (how much equity you need). Equity is how often your hand actually wins. You have a profitable call when your equity is greater than the equity the pot odds require.
What is the rule of 2 and 4? +
A quick estimate at the table: multiply your outs by 2 for each card you will see. For a one-card call you price the next card, so nine flush outs gives 18% against the exact 19.1%. Multiply by 4 when this call guarantees both the turn and the river: 36% against the exact 35.0%. That estimate runs high on big draws: a 15-out combo draw is really 54.1% where the shortcut says 60%. The calculator above uses the exact numbers.
