An equity calculator is one of the best study tools in poker. It shows how often a hand wins against another hand or against random opponents, on any board. Here's how to use one to improve your decisions.
Step 1: Pick a hand you want to review
Choose a hand from a recent session where you weren't sure about a decision — for example, calling an all-in on the flop with a flush draw.
Step 2: Enter the cards
In our poker odds calculator, type your hand (e.g. Ah Qh), your opponent's likely hand (e.g. Kd Ks) and the flop (e.g. Kh 7h 2c). Use T for tens and s, h, d, c for the suits.
Step 3: Read the results
The calculator shows your win %, tie % and overall equity. In this example, the nut flush draw has roughly a quarter of the equity against a set — a useful reminder that even big draws are underdogs to strong made hands.
Step 4: Compare with the price
Equity alone doesn't decide the play. Compare it with the pot odds you were offered using the pot odds calculator, or calculate the exact value with the EV calculator.
Step 5: Test other possibilities
You rarely know your opponent's exact hand. Try several plausible hands — a set, two pair, top pair — and see how your equity changes. If the decision is profitable against most of them, it was probably a good play.
Study tips
- Learn common matchups. Pair vs two overcards is about 55/45; a dominated hand like AK vs AQ is about 74/26.
- Check multiway equity. Set random opponents to see how even strong hands lose value against several players.
- Use it away from the table. Real-time assistance tools are prohibited on most poker sites and in casinos.
