Pot odds calculator
Pot odds compare the size of a call with the pot you could win. To break even, your chance of winning must be at least call ÷ (pot after you call). This calculator works that out, then compares it with your exact chance of hitting your outs.

Pot odds alone don’t justify a call. You hit 19.1% but need 25.0%. Implied odds or fold equity would have to make up the gap.

The pot odds formula
Required equity = amount to call ÷ (pot before the bet + the bet + your call). If the pot is 100 and your opponent bets 50, you call 50 to win a final pot of 200. You need 50 ÷ 200 = 25% equity to break even.
The same spot can be written as a ratio: the pot offers 150 to your 50, or 3 to 1.
Counting outs
Outs are the unseen cards that will most likely give you the best hand. A flush draw has 9 outs (13 cards of a suit minus the 4 you can see). An open-ended straight draw has 8.
Be careful not to count outs that also improve your opponent, such as a flush card that pairs the board when they might have a full house.
Rule of 2 and 4
A quick shortcut at the table: multiply your outs by 4 on the flop (two cards to come) or by 2 on the turn (one card to come). The calculator shows the shortcut next to the exact figure so you can see how close it is.
If you face a bet on the flop, you usually only see one more card before the next decision. That is why the calculator lets you choose between one card and two.
Frequently asked questions
How do you calculate pot odds in poker?
Divide the amount you have to call by the total pot after your call. Calling 50 into a pot that will be 200 means you need 25% equity to break even.
What is the rule of 2 and 4?
A shortcut for your chance of hitting: outs × 4 with two cards to come, outs × 2 with one. It is close for small numbers of outs and overestimates with many outs.
What are implied odds?
Implied odds count the extra chips you expect to win on later streets when you hit. They can justify a call that pot odds alone don’t support, but they depend on stack sizes and your opponent.
