Pot odds calculator quick answer
Poker pot odds are the break-even price of a call. Divide the amount you must call by the pot after your call. If the pot is $100 and the call is $50, the final pot is $150, so you need 33.3% equity. Call only when realistic hand equity beats that figure.
- The current pot input should include the opponent's bet, but not your call.
- Compare required equity with clean-out equity, not every card that merely improves your hand.
- Use two-card equity only when one call guarantees you will see both the turn and river.
- Pot odds ignore future betting; implied odds and reverse implied odds need a separate estimate.
How to calculate poker pot odds: call amount divided by final pot
The most common pot-odds mistake happens before the calculation starts. "Pot before your call" means every chip already in the middle, including the opponent's latest bet. It does not include the chips you are deciding whether to call. With $100 already in the pot and $50 to call, your $50 call creates a $150 final pot. The break-even calculation is 50 divided by 150, or 33.3%.
The next step is an equity estimate. Clean outs are cards that are likely to make your hand best. A heart may complete your flush and still lose to a full house, while an overcard may pair you but improve the opponent to two pair. Counting those as automatic wins makes the call look cheaper than it is. When ranges are uncertain, run the calculation once with a cautious out count and once with a more generous one.
Be careful with the two-card result. From the flop, a nine-out flush draw gets there by the river about 35% of the time. That number is useful for an all-in call because the price buys both remaining cards. In an ordinary single-raised pot, the turn can bring another bet. Compare the current call with the next-card chance unless you know the river is included in the price.
Pot odds cover the money already available now. Implied odds add money you expect to win on a later street when the draw arrives. Reverse implied odds account for future losses when an apparent out makes a second-best hand. Both depend on stack depth, position, opponent range, and likely action, so they should not be hidden inside an optimistic out count.
Treat a small equity edge as a close decision, not a command. Rake can erase a thin cash-game call, and an inaccurate range can move the estimate several percentage points. Rewards such as rakeback are separate from the hand calculation. They can improve long-run results, but they do not turn dirty outs or a badly priced call into sound poker math.
Pot odds chart for common bet sizes
The example starts with $100 in the pot before the opponent bets. The percentage is your break-even equity after calling that bet.
| Opponent bet | Pot before your call | Final pot after your call | Pot odds | Equity needed |
|---|---|---|---|---|
| $25 (quarter pot) | $125 | $150 | 5 to 1 | 16.7% |
| $33.33 (third pot) | $133.33 | $166.66 | 4 to 1 | 20.0% |
| $50 (half pot) | $150 | $200 | 3 to 1 | 25.0% |
| $66.67 (two-thirds pot) | $166.67 | $233.34 | 2.5 to 1 | 28.6% |
| $75 (three-quarter pot) | $175 | $250 | 2.33 to 1 | 30.0% |
| $100 (pot-size bet) | $200 | $300 | 2 to 1 | 33.3% |
Texas Hold'em outs and exact draw chances
These percentages start on the flop with 47 unseen cards. The two-card figure is relevant only when no later bet can force you to fold before the river.
| Clean outs | Typical draw | Hit on next card | Hit by river | Rule of 2 and 4 estimate |
|---|---|---|---|---|
| 4 | Gutshot straight draw | 8.5% | 16.5% | 8% / 16% |
| 8 | Open-ended straight draw | 17.0% | 31.5% | 16% / 32% |
| 9 | Flush draw | 19.1% | 35.0% | 18% / 36% |
| 12 | Flush draw plus three clean overcard outs | 25.5% | 45.0% | 24% / 48% |
| 15 | Large combo draw | 31.9% | 54.1% | 30% / 60% |

Pot Odds questions
What is the formula for pot odds?
Required equity equals the call amount divided by the final pot after your call. If $100 is already in the pot and the call is $50, divide $50 by $150. The result is 33.3%.
Does the pot size include the opponent's bet?
Yes. Enter all money already in the middle, including the bet you are facing. Do not add your own call to that input because the calculator adds it when finding the final pot.
What does 2-to-1 pot odds mean as a percentage?
Two-to-one pot odds mean you can win two units already in the pot for each unit you call. Add the two sides plus your call unit: 1 divided by 3 is 33.3% required equity.
How accurate is the Rule of 2 and 4?
It is a fast table estimate, not an exact formula. Multiply clean outs by about two for one card and four for two cards from the flop. The shortcut gets less accurate as the number of outs grows.
When should I use the turn-and-river equity result?
Use it when the current call guarantees both cards, most often in an all-in pot on the flop. If another bet can arrive on the turn, compare the current price with next-card equity instead.
Can I use this pot odds calculator for Omaha?
The pot-odds percentage is the same in every poker game, but this tool's outs calculation uses Texas Hold'em unseen-card counts. Omaha players know four hole cards and must use exactly two, so clean outs and draw probabilities need an Omaha-specific equity check.
