What the calculator shows

For each size, from a third of the pot to all-in, it shows the expected value of betting against giving up the pot now, the fold chance at which the bet breaks even, and the price your opponent gets to call. Rake is included.

Fold equity and break-even

A bluff with no chance when called breaks even when your opponent folds as often as the bet is a share of the pot it creates: bet ÷ (pot + bet). Before rake, a half-pot bluff needs a fold one time in three and a pot-sized bluff one time in two. Equity when called lowers those numbers, because a call no longer costs you the whole bet.

Where the inputs come from

Here you type in how often you think they fold and your equity when called. The full Analyser works both out from the player type you face: how often that type keeps going against each size, and your equity against the hands it continues with.
