How accurate is this range vs range equity calculator?
The simulator runs 5,000 randomized matchups per click using a fast hand evaluator. Results converge quickly and are accurate to within a fraction of a percent for typical hand ranges.
Compare two or more Texas Hold'em hand ranges, simulate flop, turn and river runouts, and see the win %, tie % and pot odds for every player in real time.
In Texas Hold'em, your opponent rarely has a single fixed hand — they have a range of possible hands consistent with the action so far. Range vs range equity measures the average win percentage of your entire range against your opponent's entire range on a given board. It's the foundation of modern poker analysis: it tells you how often the spot favors you, regardless of which exact hand either player happens to hold this time. New to the terminology?

Each player panel offers three ways to define a range. You can type hands in shorthand (e.g. AA, AKs, 32s, T5o+, 96s-, 66-99), drag the slider to pick the top X% of hands, or click cells in the grid to add or remove combos individually. All three stay in sync — tweak whichever feels fastest.
Click any of the five board card slots to choose flop, turn, and river cards. Leaving cards empty tells the simulator to randomize them. This lets you study a specific flop texture or run a fully preflop matchup.
If you want to test a real spot you played, set both hole cards for any player and the simulator will use those exact cards instead of the range for that seat.
Use Add player to introduce additional villains for multiway pots. Use the × in each row to remove a player. Uncheck a row to temporarily exclude that player without deleting them.
The calculator runs thousands of randomized matchups and shows each player's Win %, Tie % and Pot Odds. Click Stop at any time and run again to refine the result.
Most leaks in tournament and cash game poker come from playing your hand in isolation instead of thinking about how your range stacks up. A nut flush draw might feel mandatory to bet, but if your range on that board is already strong, a check might earn more. Range vs range thinking unlocks correct bet sizing, accurate bluff frequencies, and confident folds — and a calculator like this one gets you to the right answer in seconds.
Use this tool to check 3-bet ranges from each position, study how your cold-call range performs vs a button open, evaluate flop continuation bet equity on dry vs wet boards, build mental models for which turn cards favor you, and compare hand vs range matchups when you've been called or raised. For specific known hands rather than ranges, use the Poker Odds Calculator.
