Poker Pot Odds Calculator

1. Enter the pot size before your call.
2. Enter the bet you have to call.
3. Enter your number of outs, the cards that complete your hand.
4. Choose whether one or two cards are still to come, then read the price and your equity.

Pot odds are the price you are being offered to continue in a hand: the size of the bet you must call compared with the total pot you could win. They tell you the minimum chance of winning you need for a call to be profitable in the long run.

If the pot is large relative to the bet, you are getting a good price and can call with a weaker draw. If the bet is large relative to the pot, you need a strong chance of hitting to make the call worthwhile.

1. Add your call to the pot to get the total you are playing for.
2. Divide your call by that total for the equity you need, as a percentage.
3. Estimate your own equity from outs: multiply outs by two for one card, or four for two.
4. Call when your equity is at least the equity you need.

The outs shortcut is the rule of two and four, a quick and close approximation of the true drawing odds used by players at the table.

The pot is 100 and your opponent bets 50, so you must call 50 to win 150. Your equity needed is 50 divided by 150, which is about 33 percent. You hold a flush draw with 9 outs and one card to come, giving roughly 9 times 2, or 18 percent equity. Because 18 is below 33, the call loses money on price alone, so you fold unless implied odds change the picture.

Bet Size

A bigger bet relative to the pot raises the equity you need, making draws less profitable to chase.

Number of Outs

More outs mean more ways to hit, raising your equity; counting them accurately is the key skill.

Cards to Come

With two cards still to come you have two chances to hit, roughly doubling your equity compared with one card.

Implied Odds

Money you can win on later streets can justify a call even when the immediate pot odds fall short.

Common draws have well-known out counts and one-card equities.

Combining draws, such as a flush and straight together, adds outs and can turn a marginal call into a clear one.

Facing a Bet on a Draw

Decide whether calling with a flush or straight draw is profitable at the price offered.

Studying Away from the Table

Review hands to build an instinct for the prices that make a call correct.

Learning the Rule of Two and Four

See how outs translate into equity so the shortcut becomes second nature.

1. Counting Dead Outs

An out that would complete your hand but hand a rival a better one is not a true out; count only clean outs.

2. Using the Rule of Four on One Card

The times-four shortcut is for two cards to come; on the river only, use times two.

3. Ignoring the Bet Size

Chasing a draw regardless of price is the fastest way to bleed chips; the bet sets the equity you need.

4. Forgetting Implied Odds

Pot odds cover only the current bet; extra chips you can win later can change a close decision.

The pot-odds price is exact arithmetic, and the equity uses the rule of two and four, a close estimate of true drawing odds. It weighs price against equity, not the full strategy of a hand.

Divide the bet you must call by the total pot after your call. Calling 50 into a pot that becomes 150 means you need 50 divided by 150, or about 33 percent equity.

A shortcut for drawing equity: multiply your outs by two for one card to come, or by four for two cards. Nine flush outs give about 18 percent on the turn.

Outs are the cards still in the deck that complete your hand. A flush draw has nine outs, an open-ended straight draw has eight.

Call when your equity is at least the equity the pot odds demand. If you need 33 percent and hold only 18, the price is wrong unless implied odds help.

Implied odds are the extra chips you expect to win on later streets if you hit. They can justify a call that immediate pot odds alone would not.

Use times four only when two cards are still to come, such as on the flop. On the river card alone, use times two.

More is better: eight or nine outs make many draws profitable at common prices, while a four-out gutshot needs a very good price.

The pot-odds maths is the same, but Omaha out counting is more complex, so treat the equity estimate as a rough guide only.
