Work out poker equity instantly with clear inputs, formula shown and shareable results.
Equity counts a tie as half a win, so it is (wins + ties / 2) over trials, and the margin of error is the usual 1.96 standard errors of a proportion. A thousand trial simulation carries a margin of error near three percentage points, so small equity differences need far more hands before they are meaningful.
Equity
equity = (wins + ties / 2) / trials
Margin of error
margin = 1.96 x sqrt(equity x (1 - equity) / trials)
