Texas Hold'em Odds Calculator
Texas Hold'em is the most played poker game in the world, and understanding your odds is the single biggest edge you can develop. Whether you're playing a home game, a casino cash game, or a tournament, knowing your equity transforms guesswork into strategy.
How Hold'em Odds Work
In Texas Hold'em, each player receives two private cards (hole cards) and shares five community cards with the table. Your odds of winning depend on the strength of your hand relative to every possible hand your opponents could have, combined with every possible board runout.
Before the flop, with two cards known and five to come, the number of possible outcomes is enormous. On the flop, with five cards visible, there are 990 possible turn-river combinations. As more cards are revealed, the calculation becomes more precise.
Preflop Odds Reference
Preflop equity is the starting point of every hand. Here are some common matchups every Hold'em player should know:
| Matchup | Hand A | Hand B | Equity |
|---|---|---|---|
| Overpair vs underpair | AA | KK | 81% vs 19% |
| Pair vs two overcards | AKs | 54% vs 46% | |
| Two overcards vs two undercards | AK | JT | 62% vs 38% |
| Dominated hand | AK | AQ | 73% vs 27% |
| Coin flip | AKs | 77 | 47% vs 53% |
Understanding Outs in Hold'em
An "out" is any unseen card that will improve your hand to the likely winner. Counting outs is the foundation of poker math.
- Flush draw: 9 outs (13 cards of your suit minus the 4 you can see)
- Open-ended straight draw: 8 outs
- Gutshot straight draw: 4 outs
- Two overcards: 6 outs (3 of each card)
- Flush draw + gutshot: 12 outs (combo draw)
- Set to full house: 7 outs on the turn
The Rule of 2 and 4
The rule of 2 and 4 is the fastest way to estimate your equity at the table without a calculator. It works like this:
- On the flop (two cards to come): multiply your outs by 4 to get your approximate equity percentage.
- On the turn (one card to come): multiply your outs by 2.
For example, a flush draw with 9 outs on the flop gives you roughly 36% equity (9 × 4). On the turn, that drops to about 18% (9 × 2). This approximation is accurate within 1-2% for most situations and is fast enough to use in real time.
Pot Odds and Equity Decisions
Pot odds tell you the price you're getting to call a bet. If the pot is $100 and your opponent bets $50, you need to call $50 to win $150. That's 3:1 pot odds, meaning you need at least 25% equity to call profitably.
Compare your equity (from your out count or from Handsight) to the pot odds being offered. If your equity exceeds the required percentage, calling is profitable in the long run. If it doesn't, fold.
Multiway Pot Equity
Hold'em equity calculations become significantly more complex with multiple opponents. Your hand might have 70% equity heads-up but only 40% equity against three opponents. Handsight calculates equity for every player at the table simultaneously, handling up to 10 players in a single scan.
This is where a poker odds calculator becomes essential. Estimating equity against one opponent is manageable with the rule of 2 and 4. Estimating equity against four opponents while they each hold unknown cards is effectively impossible without computation.
How Handsight Works for Hold'em
Point your phone camera at the table. Handsight's on-device AI detects every visible card, including your hole cards and the community cards. It then runs thousands of Monte Carlo simulations to calculate equity for each player.
The results update as new cards appear. See your preflop equity, then watch it shift on the flop, turn, and river. Save interesting hands to review later with full equity breakdowns. No internet connection required because everything runs on your device.
