Outs and pot odds calculator

Count your outs, enter the pot and the bet you face, and see at once whether the call pays: your exact chance to hit, the equity the price demands, and how much more you would need to win later if it does not.

How the calculator works

Your chance to hit is exact. With one card to come it is your outs divided by the unseen cards: 47 on the flop, 46 on the turn. With two cards to come it is one minus the chance that both cards miss. For 9 outs from the flop that is 35.0%.

Pot odds compare the pot with the price of the call. If the pot, with the bet you face, is 150 and the call is 50, you risk 50 to win 150: pot odds of 3 to 1. As a percentage you need to win at least 50 out of the 200 that will be in the pot, that is 25%. This is the "equity you need to call".

The verdict compares the two. If your chance to hit is higher than the equity you need, the call makes money on average even if nothing more is ever bet. If it is lower, the call can only pay through implied odds: extra chips you win on later streets when you hit. The calculator shows how much extra that has to be.

The average result in chips assumes you win the pot exactly when you hit and lose your call when you miss. It leaves out later betting, and outs that are not really outs.

Choosing the right number of cards to come

A common mistake with pot odds is to use the two-card figure on the flop. If you call a bet on the flop, you usually face another bet on the turn, so this call buys you one card: 9 outs give 19.1%, not 35.0%. Use two cards only when no more betting can happen, for example when you or your opponent is all-in.
