Calculate win/tie/lose percentages for two poker hands — preflop or with board cards.
—
Select two starting hands from the dropdowns and click Calculate Equity. The tool uses pre-computed equity tables for common Texas Hold'em matchups. Equity is calculated as win% plus half the tie%. Understanding preflop equity helps you make better decisions about raising, calling, and shoving all-in.
Even the biggest favourite in poker — AA vs KK — wins only about 82% of the time. This means KK wins roughly 1 in 5 times as a 4:1 underdog, which is why bad beats feel frustrating but are mathematically expected. Coin-flip situations (like AK vs QQ, roughly 50/50) are extremely common in tournament play.
Equity is the long-run expected share of the pot. When you have 65% equity in a £100 pot, your expected value is £65. Making decisions based on equity rather than emotions is the cornerstone of winning poker. Use this calculator to internalise common matchup percentages before you next sit at the table.
