How It Works

Pick your cards, set the stacks, and the calculator does the math. Here's what each number means.

Equity vs Villain

Use the Range tab on the villain seat to test your hand against a full range, or the Exact hand tab for a specific holding. The tool calculates how often you win across all possible runouts.

Pot Odds

The price the pot is offering you. If you need to call $50 into a $200 pot, you're investing 20% of the final pot. Your equity needs to exceed this price for a profitable call.

Implied Odds

When direct pot odds fall short, implied odds measure how much more you need to win on later streets. Deeper stacks and nut draws improve implied odds. Villain is more likely to pay off a big hand.

Draw Quality

Not all draws are equal. A nut flush draw (holding the ace) has clean outs and strong implied odds. A non-nut flush draw risks making a second-best hand. That's reverse implied odds.

Board Texture

Dry boards (rainbow, unconnected) produce fewer draws and more stable hand values. Wet boards (suited, connected) create many drawing possibilities and make hand values volatile across streets.

SPR

Stack-to-pot ratio is your effective stack divided by the pot. It appears under Facing a bet. Lower SPR means more of your stack is already committed to the hand.

Worked example: Q4o on 2♣ 4♥ 7♠ vs a random hand

One of the most-searched spots for this calculator is Queen-Four offsuit on a 2-4-7 rainbow flop against a single random opponent. It's a revealing example because Q4o looks like air, but on this specific flop it has more equity than most players assume.

The situation: you're holding Q♦4♠. The flop comes 2♣ 4♥ 7♠. Your opponent's range is a random hand (for learning purposes, real players aren't random).

Your equity: ~65%. Why it's higher than it looks:

  • Second pair, not air. Your fours currently beat unpaired hands, but lose to a seven, an overpair, and stronger made hands.
  • A queen can improve you. Pairing your queen makes two pair, though it does not guarantee a win against every hand or runout.
  • The random range matters. A uniformly random opponent holds many hands that missed this flop. A player continuing against a bet may have a much stronger range.
  • Dry does not mean draw-free. There is no immediate flush draw, but 5-3 has an open-ended straight draw, and later cards can change which hand is ahead.

The lesson: equity is shaped by both cards in play and cards on the board. A middling hand on a dry low-card flop is often stronger than a "bigger" hand on a coordinated one. That's the gap the exploitative trainer drills, until the number is in your head before you see it on the screen.

Try it in the calculator above: enter Q♦ 4♠ for Hero and board 2♣ 4♥ 7♠, then open Villain's range and pick the Any two (random) preset. The calculator returns about 65%, Hero's equity against a uniformly random hand. Narrow Villain to a real range or specific cards to see how the number shifts against an actual opponent.

Worked example: pocket aces vs pocket kings preflop

The most lopsided premium clash players ask about is aces against kings before the flop. It feels close because both hands are monsters. It is not close.

The situation: you hold A♠A♥. Villain holds K♠K♥. The money goes in preflop, no board yet.

Your equity: ~83%. Aces are almost a 5-to-1 favorite. Why the gap is so wide:

  • Kings are drawing to two outs. Villain needs one of the two remaining kings to arrive, or a runout that backs into a straight or flush.
  • Stack depth does not change it. All-in preflop, the number is fixed by the cards. Deeper stacks only change how much you win, not how often.
  • It is not a coinflip. A pair against a lower pair is one of the biggest preflop edges in poker, unlike a pair against two overcards, which is closer to a race.

The lesson: a higher pair crushes a lower one, which is why stacks routinely go in preflop with kings even knowing aces are sometimes out there. For how each of these hands plays past the flop, see how to play pocket aces and pocket kings. The exact number for this and every classic collision, suited and offsuit, lives in the AA vs KK matchup page and the full preflop matchups tables.

Verify it above: enter A♠ A♥ for Hero and K♠ K♥ for Villain, no board. The calculator returns about 83%.

Worked example: a flush draw vs top pair on the flop

Draws feel like underdogs because you have not made a hand yet. When you are all-in on the flop and see both cards, a big draw is often the favorite.

The situation: you hold A♠K♠ on a Q♠ 7♠ 2♦ flop, the nut flush draw with two overcards. Villain holds Q♥J♥ for top pair. All in on the flop.

Your equity: ~53%. The draw is a slight favorite over the made hand. Where it comes from:

  • Nine flush outs. Any of the nine remaining spades completes the nut flush.
  • Live overcards. An offsuit ace or king pairs you above queens, adding clean ways to win that top pair cannot ignore.
  • Two streets to hit. Fifteen-ish ways to improve, drawn twice, is enough to edge in front of a single pair.

The lesson: compare equity with the price of calling. Heads up, a draw with more than 50% equity is profitable to call all-in before rake. With money left to bet, future action can stop you realizing all of your two-card equity. Work the price separately with pot odds for a flush draw. The same split applies to an open-ended straight draw, a gutshot, or two overcards alone.

Verify it above: enter A♠ K♠ for Hero, board Q♠ 7♠ 2♦, and Q♥ J♥ for Villain. The calculator returns about 53%.

Worked example: a set vs a flush draw on a wet board

Flopping a set is a monster, but on a board where a flush draw is live it is not the lock it feels like.

The situation: you hold 9♦9♣ on a 9♠ 6♠ 2♥ flop for top set. Villain holds A♠K♠, the nut flush draw with two overcards. All in on the flop.

Your equity: ~75%. Strong, but villain still wins about one time in four. Why it is not higher:

  • Villain's outs are almost all flush. The nine spades are the danger. The overcards barely matter, because a pair of aces still loses to three nines.
  • The set can redraw. A paired board can give you a full house or quads, beating a flush. Villain completing a flush on the turn does not always settle the hand.
  • Texture is doing the work. The same set is a much bigger favorite on a dry rainbow board where no flush can complete.

The lesson: wet boards compress equity. A hand that looks unbeatable leaks a quarter of its value when a flush draw is out, which is why protection and sizing matter more on connected, suited textures than on dry ones.

Verify it above: enter 9♦ 9♣ for Hero, board 9♠ 6♠ 2♥, and A♠ K♠ for Villain. The calculator returns about 75%.

What poker equity actually means

Equity is the percentage of the pot you'd win if both players went all-in and ran out the remaining streets. Against one opponent, pocket aces have ~85% equity preflop; a flush draw on the flop has ~35% against a made hand. Every decision in poker is a bet, literally or implicitly, that your equity plus fold equity exceeds the price you're paying.

This calculator handles the three versions that matter in practice: hand vs hand (pocket pair vs big ace), hand vs range (your hand vs the hands your opponent could have based on their actions), and range vs range (both players' full distributions, available in the range advantage calculator).

If you want the full tutorial with worked examples and a framework for reading equity at the table, see the poker equity guide. If you want to drill spots against realistic opponents, the exploitative poker training arena generates them continuously. And if adjusting to specific opponents is new to you, exploitative poker strategy explains the approach in plain language.

The training arena puts you in these exact spots, and teaches you to exploit them.

Frequently asked questions

How accurate is this poker equity calculator? +

Once there is a flop, hand against hand is exact: the calculator deals out every possible remaining card, so those results match PokerStove, Flopzilla, and similar industry calculators. Preflop hand against hand samples 5,000 random boards, and hand against a range samples 2,000 deals on any street, so those numbers can move a point or two between runs. That is plenty for study, just don't read anything into a half-point gap.

What's the difference between hand vs hand and hand vs range equity? +

Hand vs hand gives you the percentage against one specific holding, useful for postflop shove decisions where you know or assume a specific hand. Hand vs range gives you the percentage against the entire distribution of hands your opponent could have. Range equity is what actually matters in real play, because you almost never know the exact hand.

Do I need to know equity percentages at the table? +

You don't need exact percentages. You need useful approximations. Know that a flush draw hits by the river about 35% of the time but only about 19% on the next card, the direct-odds number if you fold after a miss and pay no further bets. An open-ended straight draw is about 31% and 17%, top pair is ~75% against a random hand, and overpairs are ~80%. Most decisions collapse to four or five reference points. The calculator is where you build that intuition.

Is this poker equity calculator free? +

Yes. No signup, no account, no paywall. It runs entirely in your browser.

Can I calculate equity on a turn or river card? +

Yes. Enter any board (1-5 cards) and the calculator handles postflop, turn, and river equity. All runouts are enumerated exhaustively when possible.
