Poker Equity Calculator

Introduction

This Poker Equity Calculator shows how often your hand wins a pot of Texas Hold'em. Pick your hole cards, add the flop, turn, and river if you know them, and the tool runs thousands of fake hands to find your odds.

You can set up to 10 players. Give each one two exact cards, or give them a range of hands like "TT+, AKs" using the text box, the strength slider, or the 13x13 grid.

When you press Calculate, you get:

• Win %: how often you have the best hand.
• Tie %: how often you split the pot.
• Equity %: your average share of the pot.
• Pot odds needed: the worst price you can pay and still call.
• Street-by-street equity: how your odds move from preflop to the river.

You also see which hands you win with most, like pairs, flushes, or straights, plus a step-by-step math breakdown. Use it to study spots, check tough calls, and learn where your money goes.

How to use our Poker Equity Calculator

Pick the community cards, then give each player a hand or a range. The calculator runs thousands of fake hands and shows each player's win %, tie %, equity %, the pot odds you need to call, and how equity changes street by street.

Community Board: Click any of the five card slots to pick a flop, turn, or river card. Choose a rank, then a suit, then press Confirm. Leave slots empty and the tool deals those cards at random. Use "Clear Board" to start over.

Include in simulation: Turn this switch off for any player you want to leave out of the hand. You need at least two players switched on.

Specific Hole Cards or Range: Choose "Specific Hole Cards" if you know the exact two cards. Choose "Range" if the player could hold many different hands.

Hole cards: Click each of the two card slots and pick the rank and suit. The green box then shows that player's current hand and any draws.

Range shorthand: Type hands in the box, like TT+, AQs+, AKo, 66-99. Split each part with a comma. Red text means the tool did not understand a part.

Preflop strength band: Drag the two handles to pick a slice of hands from strongest to weakest. 0% is the very best hands. This fills the grid for you.

Hand grid: Click a cell to add or remove that hand. Right-click, long-press, or press S on a cell to pick exact suit combos. Use the colour buttons to mark groups of hands, and "Select all 169" or "Clear range" for fast changes.

Add Player / Remove: Add up to 10 players. Remove any player you no longer need. Player 1 is always the Hero used in the step-by-step math.

Precision / Speed: Pick Fast, Balanced, or Precise. More hands give a more exact answer but take longer. You can press Stop while it runs.

Calculate and Reset: Press Calculate to run the simulation and see the results, charts, and worked steps. Press Reset to clear all cards and ranges and start fresh.

What Is Poker Equity?

Poker equity is your share of the pot. It is the percent of the time your hand would win if the rest of the cards were dealt out again and again. If you have 60% equity in a $100 pot, your hand is worth about $60 right now. This is the same idea as an expected value for a bet, just written as a percent.

Win, Tie, and Equity

These three numbers are not the same. Win % is how often you hold the best hand alone. Tie % is how often you split the pot with someone else. Equity % mixes both: every win counts as a full pot, and every tie counts as a piece of it. Two players who chop each get half, so that trial adds 0.5 to each score. All players' equity always adds up to 100%.

Pot Odds and Break-Even Calls

Pot odds tell you if a call makes money. Take your equity E and use this rule: you need pot odds of at least (1 − E) / E to 1. With 25% equity you need 3 to 1, so the pot must pay you three dollars for each dollar you call. If the price is better than that, calling wins money over time. If it is worse, folding is better.

Hand Ranges

You rarely know what an opponent holds. Instead, good players guess a range, a group of hands that player might have. Shorthand makes ranges quick to write:

• AA: a pocket pair of aces
• AKs: ace-king, same suit (suited)
• AKo: ace-king, different suits (offsuit)
• TT+: tens and every pair above them
• 66-99: sixes through nines

There are 1,326 possible starting hands in Texas Hold'em. A range that holds 132 of them covers about 10% of all hands. Suited hands have 4 combos each, offsuit hands have 12, and pairs have 6. That count comes straight from a Combination Calculator: 52 cards chosen 2 at a time.

Streets Change Everything

Equity shifts as cards hit the board. Preflop, hands are close in value. On the flop, three shared cards appear and the gap widens. The turn and river leave fewer unknown cards, so equity moves toward 0% or 100%. A big draw like a flush draw can hold strong equity on the flop and lose it all when the river bricks.

Hand Rankings, Best to Worst

1. Straight Flush
2. Four of a Kind
3. Full House
4. Flush
5. Straight
6. Three of a Kind
7. Two Pair
8. One Pair
9. High Card

Every player makes the best five-card hand from their two hole cards plus the five board cards.

Why Monte Carlo?

Counting every possible board by hand takes far too long. A Monte Carlo simulation deals thousands of random boards instead and counts the results. More hands dealt means a tighter, more trustworthy answer. Ten thousand trials gives a fast estimate; two hundred thousand gives a sharp one. The spread of the results narrows in line with the margin of error for the sample size you pick.
