Poker Equity Calculator: How Equity Works in Poker

Equity is your share of the pot based on your probability of winning the hand. If you have 60% equity in a 100-chip pot, your equity is 60 chips. Understanding equity — and how it changes as community cards are dealt — is the mathematical foundation of every poker decision.
Hand vs Hand Equity
The simplest equity calculation compares two specific hands before the flop:
| Matchup | Favorite | Equity |
|---|---|---|
| AA vs KK | AA | ~82% vs ~18% |
| AKs vs QQ | ~46% vs ~54% | |
| AKo vs 76s | AKo | ~60% vs ~40% |
| JJ vs AKs | JJ | ~54% vs ~46% |
| AA vs 87s | AA | ~77% vs ~23% |
Notice that even the worst pre-flop matchup (KK vs AA) still has 18% equity. In poker, no hand is ever drawing dead before the board runs out.
Hand vs Range Equity
In practice, you never know your opponent's exact cards. Instead, you estimate their range — the set of all hands they could plausibly hold — and calculate your equity against that entire range.
For example, if you hold AKs and your opponent's range is {QQ+, AKs, AKo}, your equity is roughly 40%. Against a wider range of {88+, ATs+, KQs}, your equity improves to roughly 55%. The wider your opponent's range, the better your equity with strong hands.
How Equity Changes Post-Flop
Equity is not static. It shifts dramatically as board cards are revealed:
- Pre-flop — Equities are closest to 50/50; variance is highest
- Flop — Biggest equity shift. The flop reveals 60% of the board
- Turn — Drawing hands either improve significantly or lose outs
- River — Equity becomes binary: 100% (winner) or 0% (loser)
Equity Realization
Having high equity does not guarantee you will realize it. Equity realization depends on position, playability, and stack depth. Suited connectors have excellent equity realization because they make straights, flushes, and two-pair often. Offsuit weak aces have poor equity realization because they frequently make dominated top-pair hands.
