Implied odds calculator
Enter the pot, the bet you face, your outs and the money the opponent has behind. See how much more you must win after your draw comes in for the call to pay.
With what you expect to win when you hit, the call makes money over time.
How the figure is worked out
The calculator uses your chance to hit on the next card only, because after that card you will usually face another bet. On the flop there are 47 cards you have not seen, on the turn 46, so nine outs give 19.1% on the flop and 19.6% on the turn.
An example: there is $100 in the pot, the opponent bets $50 and you have a flush draw on the flop. Without later money the call loses $11.70 on average, because you win $150 19.1% of the time and lose $50 the other 80.9%. To break even you must win $61.11 more on the turn and the river when the flush comes in. An opponent with $300 behind who calls a bet after the flush lands makes that easy to reach. One who stops betting when the third heart comes does not.
The same money can run the other way. When your hand improves but still loses, such as a small flush against a bigger one, you pay more on later streets instead of winning more. Count those outs as half an out, or leave them out.
Questions
What are implied odds?
The money you expect to win on later streets when your draw comes in, on top of what is in the pot now. A call that loses on pot odds alone can pay when the opponent has money behind and will pay you after you hit.
Why does the calculator use one card and not two?
Because on the flop you will usually face another bet on the turn. Two cards to come is the right figure only when you are all-in or the opponent will not bet the turn.
When are implied odds worth little?
When the opponent has little money behind, when the card you need is easy to see, such as a fourth card of one suit on the board, and when hitting can still lose to a bigger hand.
