Hand vs hand. Hand vs range. Texas Hold'em equity calculated by Monte Carlo simulation, running entirely in your browser. No signup, no upsell — just the math.
Click cards to build each hand. Add board cards for flop/turn/river equity. Range mode lets you put a hand against a group of holdings.
Poker equity is your share of the pot based on your probability of winning the hand if it goes to showdown. If you have 60% equity, the math says you'll win 60 cents of every dollar in the pot in the long run. Equity is the foundation of nearly every poker decision — pot odds calculations, expected value math, bluff frequency, range vs range analysis — all of it traces back to equity.
This page runs a Monte Carlo simulation entirely in your browser. The engine deals out tens of thousands of random board cards, evaluates each player's best 5-card hand at the river using a standard hand evaluator, and counts wins, ties, and losses. The percentages converge on the true equity within fractions of a percent. The default is 50,000 simulations, which produces results accurate to about 0.2%. No data is sent to any server.
Hand vs hand is the simplest case: two specific holdings (e.g., AhKh vs QsQc) and a board state. The engine generates random board completions, picks each player's best 5-card hand, and tracks wins.
Hand vs range is more useful in practice. Most of the time you don't know exactly what the opponent has — you have a guess at what range of hands they're playing. The calculator picks a random hand from the opponent's range each simulation, then runs the same comparison. Ranges include common 3-bet ranges, calling ranges, and a custom 13×13 grid for full control.
Range vs range is the deepest mode and matches what GTO solvers do internally. Both you and your opponent have ranges; the calculator samples a random hand from each every simulation. Useful for analyzing whole-range scenarios in tough spots.
Every poker player should know these by heart. Try running them in the calculator above to verify:
This calculator uses Monte Carlo simulation, which is fast and very accurate but not exact. PokerStove uses exhaustive enumeration — it considers every possible board — and gives 100% exact equities. Both approaches converge on the same answer; PokerStove is just deterministic about it.
The benefit of Monte Carlo is speed: hand-vs-hand calculations finish in under a second, and large range-vs-range scenarios take just a few seconds. For practical decisions, the precision difference between Monte Carlo and exact enumeration is irrelevant. If you need exact, run the calculator a few times and average the results.
Accuracy is the whole point of an equity calculator. This engine has been verified against canonical equities published by CardFight.com (which uses exhaustive enumeration of all 1,712,304 possible board runouts) and authoritative published values from sources like Upswing Poker and PokerBankrollBlog.
Verified test cases include:
All deltas fall within the natural variance of 100,000-trial Monte Carlo simulation (statistical margin of error ≈ ±0.16%). This means the engine produces results indistinguishable from exact enumeration for any practical poker decision. One important note: equity for a specific suit configuration (e.g., AcAs vs KhKd) can differ slightly from the average across all suit configurations of the same matchup (e.g., "AA vs KK" generically) — this is true equity behavior, not a calculator quirk.
Once you understand equity, the next layer is using it to make better decisions in real spots. Combine equity with the pot odds calculator to determine whether a call has positive expected value. For tournament situations, our ICM calculator (coming soon) converts chip equity into dollar equity at final tables. And for postflop GTO analysis, the free GTO solver handles full game-tree solutions.
The questions players ask most often about poker equity.
Poker equity is your share of the pot based on the probability of winning the hand. If you have 60% equity, the math says you'll win 60 cents of every dollar in the pot in the long run. Equity is the foundation of nearly every poker decision — pot odds, expected value, bluff frequency — all of it traces back to equity calculations.
It uses Monte Carlo simulation: the calculator deals out tens of thousands of random board cards, evaluates each player's best 5-card hand at the river, and counts wins, ties, and losses. The percentages converge on the true equity within fractions of a percent.
The simulation runs entirely in your browser — no server calls, no data uploaded.
For hand-vs-hand calculations, the results match PokerStove to within 0.1% with 50,000+ simulations (the default). For range calculations, accuracy depends on range size — small ranges converge fast, large ranges may show ±0.5% variance.
PokerStove uses exhaustive enumeration which is 100% exact; this calculator uses Monte Carlo which approaches exact but doesn't quite reach it. The accuracy is more than sufficient for any practical decision.
AKs has approximately 46.2% equity against QQ preflop. This is the classic "race" or "coin flip" matchup in poker — slight underdog for the high cards against the pocket pair, but the suitedness of AK closes most of the gap. AKo is closer to 43.5% against QQ.
Try this matchup in the calculator above to verify.
AA has approximately 81–82% equity against KK preflop. This is the most lopsided common matchup in Hold'em — the under-pair has only about an 18–19% chance to win, mostly from hitting a set on the board (about 12% of the time, with the remainder coming from runner-runner straights and flushes).
Yes. The calculator includes preset ranges for common situations: "TT+, AQ+" (tight 3-bet range), "JJ+, AK" (premium calling range), "any pair," "any broadway," and a fully custom range builder where you click hands on a preflop grid to add or remove them.
Hand-vs-range calculations are slightly slower than hand-vs-hand but still complete in 1–3 seconds for typical ranges.
Monte Carlo simulation introduces small variance — the result on consecutive runs will typically differ by 0.1–0.3% for hand-vs-hand at 50,000 simulations. This is expected and normal. The advantage is speed; the cost is tiny variance.
If you need exact equity, run the calculator 3 times and take the average. PokerStove-level exactness requires running every possible board, which would take much longer in browser.
Yes for the equity portion — but for tournament decisions you also need ICM (Independent Chip Model) to convert chip equity into dollar equity. ICM matters most at final tables and pay jumps.
We have a separate ICM Calculator on the Tools & Resources page that handles the chip-to-dollar conversion.
