Poker Hand Equity Calculator

Texas Hold’em equity calculator. Run Monte Carlo simulations for hand-vs-hand and hand-vs-range spots with optional flop, turn, and river cards.
What does a poker equity calculator tell you?
A poker equity calculator reports how often each hand wins, ties, and loses a pot if the hand is dealt to showdown. Enter two hands — or a hand against a range of possible holdings — add any known board cards, and the tool simulates thousands of runouts to estimate each player’s share of the pot. The output is a single percentage: your equity.
How accurate is the Monte Carlo method?
Monte Carlo simulation deals the remaining cards at random many times and counts the results. Accuracy improves with the square root of the iteration count: 80,000 runouts land within roughly 0.35 percentage points of the true equity, and 200,000 tighten that to about a quarter of a point. We validate the underlying seven-card evaluator against published benchmarks so the engine is provably correct, not just plausible.
| Matchup | Equity (higher hand) | Type |
|---|---|---|
| AA vs KK | ~82% / 18% | Over-pair dominance |
| AKs vs 22 | ~50% / 50% | Classic coin flip |
| AKo vs 22 | ~47% / 53% | Race, pair edge |
| AKo vs AQo | ~74% / 26% | Domination |
| 72o vs AA | ~12% / 88% | Worst vs best |
These reference numbers are the industry-standard equities every serious solver reproduces. If a calculator disagrees with them, its evaluator is broken. Ours matches each spot within Monte Carlo sampling error.
How do you read equity against a range?
Real decisions are rarely hand versus hand. When you face a raise, the opponent holds one of many possible hands. Range mode expands notation like QQ+, AKs, AJs+, KQo into every matching combination and averages your equity across all of them, weighted by how many combos each holding represents. That average is what your call is actually up against, not the single hand you fear most.
Why study equity away from the table?
Poker rooms ban real-time assistance devices, so equity work belongs to study sessions. Reviewing hands with a calculator builds the pattern recognition that lets you estimate equity instantly while playing. Over time you learn that a flush draw with two overcards is roughly a coin flip against top pair, or that a dominated ace is in far worse shape than it feels. For bankroll planning around that variance, pair this with our poker variance simulator and, for tournament spots, the ICM calculator. The same data-first approach drives our live prediction market dashboard.
Key Takeaways
- Equity is your expected share of the pot at showdown — win percentage plus a split of any ties.
- Monte Carlo accuracy scales with iterations; 80,000–200,000 runouts converge within half a percentage point.
- Range mode reflects real decisions better than hand-vs-hand, because opponents hold a distribution of hands.
- The engine matches published benchmarks such as AA vs KK at ~82/18 and AKo vs AQo at ~74/26.
- This is a study tool — real-time assistance is banned in every regulated poker room.
