Compare calculators
Both calculators run independently β change the inputs on either side to compare results.
Sit & Go ROI Calculator
Measures your long-run profitability in 9-player Sit & Go tournaments by comparing prize payouts to total buy-ins spent. Use it after any sample of SNGs to benchmark your edge.
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.
