Callers behind you are people you expect to call after you; each is assumed to put in the same amount as you, which makes the price better. Outs that are not clean are cards that help you but could also complete an opponent's better hand; they are taken off your outs.
Reverse implied odds are the money you lose on later streets when you make your hand but someone has a better one, such as a small flush drawing dead to a bigger flush.
| Draw | Outs | Turn: 2× | Turn exact | Flop: 4× | Flop exact |

Equity when called is how often you still win if the bet is called; use 0 for a pure bluff.
Bluff must work is the share of the time your opponent has to fold for the bet to break even. MDF (minimum defense frequency) is the share of the hands an opponent must continue with so that a bettor's bluffs cannot profit automatically; they can fold the rest. Balanced bluff share is the part of a polarized river betting range that can be bluffs so the opponent is indifferent to calling, equal to bet / (pot + 2 × bet). These are theory benchmarks for one street, not a strategy by themselves.

Chips are not worth the same as money when prizes are fixed. Enter the stacks and prizes; the calculator finds the equity you need to call an all-in, and how much more than the plain pot-odds number that is. Leave stacks empty for players who are not at the table.
Stacks are counted after blinds and antes are posted. The pot is twice the smaller stack plus the dead money.
| Outcome | Your stack | Your prize equity |

Prize equity uses the Malmuth-Harville model, the standard ICM calculation. Bubble factor is what you lose by busting divided by what you gain by winning, so a factor of 1.5 means a loss costs 1.5 times what a win earns.
