Preflop Equity Calculator
Estimate your preflop equity percentage in Texas Hold'em based on hand strength, table position, opponent range, and the action type. Use it to study open-raising, 3-betting, and 4-betting decisions.
Preflop Equity
85 %
Over 70% equity reflects premium holdings such as big pairs, often near 85% heads-up. Build the pot aggressively; flatting wastes a large preflop edge.
This is your estimated preflop win share against the opponent's range; 50% is a coin flip and premium hands like AA-QQ sit near 80%+ heads-up.
Poker Variance Calculator
Model the expected swings in your poker results over a large sample of hands. Use it to set realistic bankroll goals and mentally prepare for inevitable downswings.
