Quick answer
What is a poker odds calculator?
A poker odds calculator computes equity — your probability of winning a hand — by simulating thousands of random outcomes for the remaining cards. Enter your hole cards, any known board cards, and the player count; it returns your win percentage, outs, and best current hand, ready to compare against the pot odds you're offered.
Powered by Monte Carlo simulation — see the calculator below.

Worked Example: Calculating a Flush Draw's Equity
Say you hold A♠K♠ and the flop comes Q♠J♠ 2♦. You have two spades in your hand and two more on the board — a flush draw, plus two overcards.
There are 13 spades in the deck. Four are already visible (your two, plus the two on the flop), leaving 9 unseen spades — your outs. Any of those 9 cards on the turn or river completes your flush.
Using the rule of 2 and 4: with two cards still to come (turn and river), multiply outs by 4 — 9 × 4 = 36%, close to the calculator's simulated ~35% for a flush draw. With only one card left to come, multiply by 2 instead — 9 × 2 = 18%, close to the ~19% figure in the cheat sheet above.
Now compare that to the price you're being offered. If an opponent bets $100 into a $100 pot, you must call $100 to win a $300 pot — you need 100 ÷ 400 = 25% equity to break even. With roughly 36% equity from the flush draw, calling is profitable on the math alone, before counting any extra value from hands you might win after making your flush (implied odds).
Common Preflop Matchups
These are widely-accepted approximate all-in equities for classic Texas Hold'em preflop confrontations, heads-up (two players, cards face up). Use them to build intuition before you check a specific hand in the calculator above.
| Matchup | Favorite | Underdog | Note |
|---|---|---|---|
| AA vs KK | ~82% | ~18% | The classic "cooler" — a big pair over a big pair. |
| AA vs AKs | ~88% | ~12% | Dominated: the aces block the ace outs; the suited K helps a little. |
| AK vs QQ | ~57% | ~43% | The classic near-coinflip: overcards vs a lower pair. |
| AKs vs 22 | ~50% | ~50% | "Race": overcards + suit vs a small pair is roughly even. |
| AK vs 72o | ~66% | ~34% | Two live overcards dominate the weakest starting hand. |
| KQ vs KJ | ~72% | ~28% | Shared king, better kicker: domination, not a coinflip. |
Equities are approximate and rounded, for heads-up all-in situations with no cards on the board. Exact numbers shift with suits and specific cards — run your own hand in the calculator for precise figures.
Poker Odds Cheat Sheet (Outs to Percentage)
A quick reference for turning your number of outs into a rough chance to improve, using the "rule of 2 and 4": multiply outs by 2 for one card to come (turn or river), and by 4 on the flop for both cards to come. It is an educational shortcut, not an exact figure.
| Draw | Outs | One card (×2) | Flop to river (×4) |
|---|---|---|---|
| Gutshot straight draw | 4 | ~8.5% | ~16.5% |
| Two overcards | 6 | ~13% | ~24% |
| Open-ended straight draw (OESD) | 8 | ~17% | ~31.5% |
| Flush draw | 9 | ~19% | ~35% |
| Flush draw + gutshot | 12 | ~26% | ~45% |
| OESD + flush draw (combo) | 15 | ~32% | ~54% |
Percentages are approximate rounded estimates from the rule of 2 and 4. Actual equity depends on live outs and the exact board — use the calculator above for precise numbers.

▶What is the difference between equity and pot odds?
Equity is your share of the pot based on your chance to win the hand. Pot odds are the price you are being offered to call, expressed as a ratio of the current pot to the amount you must call. As an educational rule of thumb, calling is mathematically break-even when your equity percentage is at least as high as the amount to call divided by the total pot after your call. This calculator shows your equity so you can compare it against the pot odds in front of you.
▶How many simulations does the calculator run, and how accurate is it?
Each calculation runs a Monte Carlo simulation over thousands of random runouts of the remaining cards. That sample size keeps the estimated equity within roughly 1-2% of the exact mathematical value for most spots, which is close enough to line up with dedicated poker odds software. Adding more known cards (flop, turn, river) makes the estimate tighter because fewer unknowns remain.
▶Is the poker hand checker free, and do I need to sign up?
Yes. The poker odds and hand checker are free to use with no account, download, or signup required. It runs entirely in your browser, so you can check a hand's equity and outs instantly. This is an educational math tool for studying probabilities, not a gambling service.
▶What is the rule of 2 and 4 in poker?
The rule of 2 and 4 is a quick way to turn your outs into an approximate percentage chance of improving your hand. With two cards still to come (the turn and river), multiply your outs by 4. With only one card to come, multiply by 2 instead. It's an estimate, not an exact figure — the calculator above runs a full simulation for a precise number.
▶What's the difference between poker equity and outs?
Outs are the specific unseen cards that would improve your hand — for example, 9 remaining spades complete a flush draw. Equity is the resulting percentage: your overall probability of winning the pot once all outs, opponent ranges, and future cards are accounted for. Outs are a raw card count; equity is the probability that count translates into.
