How to calculate pot odds
Pot odds compare the pot you can win with the amount you must call. Required equity = call / (pot including their bet + call) × 100.
Example: the pot is $100 before your opponent bets $50. There is now $150 in the middle, and calling $50 makes the final pot $200. You are getting 150:50, or 3:1 pot odds, and need 50 / 200 × 100 = 25% equity to break even. This assumes no rake or further betting.
The same number is often quoted as a ratio. Being laid 150-to-50 reduces to 3:1, and a 3:1 price needs 1 / (3 + 1) = 25% equity. Percentages and ratios are interchangeable — the calculator shows both because different players think in different units.
The single most common error is leaving the bet you face out of the pot. That money is already in the middle and you collect it when you win, so it counts. Using the pre-bet pot in the example above would tell you that you need 33% instead of 25% — a wide enough gap to turn a clearly profitable call into a fold. This calculator takes the pot and the bet as separate inputs and adds them for you, so the mistake is not available to make.

Bet sizes below are fractions of the pot before the bet, facing one opponent with no intervening calls or raises. Percentages and ratios are rounded.
| Bet size | Pot odds | Equity needed |
|---|---|---|
| 1/4 pot | 5:1 | 16.7% |
| 1/3 pot | 4:1 | 20.0% |
| 1/2 pot | 3:1 | 25.0% |
| 2/3 pot | 2.5:1 | 28.6% |
| 3/4 pot | 2.33:1 | 30.0% |
| Pot-sized | 2:1 | 33.3% |
| 2x pot | 1.5:1 | 40.0% |
Pot odds are the price; equity is your estimated share of the pot. The rule of 2 and 4 estimates draw odds from outs, not pot odds. Use two-card draw odds only when both remaining cards are guaranteed, such as a flop all-in. Otherwise, future bets can change the cost.
Implied and reverse implied odds
Raw pot odds only count the chips already in the middle. Implied odds add the money you expect to win on later streets when your draw gets there, which lowers the equity you need right now. Calling $50 into $150 needs 25%; if you will extract another $200 when you hit, the requirement drops to 50 / 400 = 12.5%. Only count money you will realistically collect — a scare card that kills the action, a short opponent stack, or a player who never pays off means those implied odds are imaginary.
Reverse implied odds are the mirror image: money you expect to lose when you improve and are still behind. Second-best flushes and idiot-end straights are the classic cases, where hitting your card costs you more than missing would have. When reverse implied odds are live, treat the calculator's number as a floor and demand extra equity on top.
Pot odds give you the threshold, not the decision — you still need your actual equity to compare against it. Count outs with the poker odds calculator, or get exact numbers against a hand or range with the equity calculator. In tournaments, check the spot against the ICM calculator too: near a pay jump, a chip-EV-correct call can still be a real-money mistake.
