What is equity in poker?

Poker equity is the one number that turns “I think I am ahead” into something you can check. Here is what it means, how to read it, and where it stops being the whole story.

Everything else on this page is a consequence of those two lines. You can check any number here in our poker equity calculator — it is the same engine that produced them.

A worked example

You hold 8h 7h. The flop is Kh 5h 2c: you have a flush draw and nothing else. Your opponent turns over As Ad. With the cards face up, there are exactly 990 ways the turn and river can come, and you win 380 of them. That is an equity of 38.4%, and the aces hold 61.6%.

Now put money on it. Say the pot is $50 on the flop and your opponent moves all-in for $50.

• If you call, the final pot is $150 — the $50 that was there, his $50, and your $50.
• Your share of that pot is 38.4% of $150, which is $57.60.
• You paid $50 to get it. Calling is worth about +$7.60.

That is the whole skill in miniature. Equity told you how often you win. The pot told you what winning pays. The call is correct because the first number was large enough for the second. Because both players are all-in, nothing else can happen — which is why all-in spots are the only ones where raw equity answers the question on its own.

Equity versus pot odds

These two get confused constantly, so hold them apart like this:

• Equity is about the cards. How often does my hand win? It comes from counting boards.
• Pot odds are about the chips. What share of the final pot is my call? It comes from counting money.

Put them side by side and you have a decision. A $50 call into a $150 final pot is 33% of the pot, so you need 33% equity to break even. You had 38.4%, so you call. If you had only held a gutshot — four outs, about 16% — the same call would lose money every time you made it.

The full mechanics of that comparison, including what happens when there is still betting to come, live in pot odds. The number that ties both of them to actual money is expected value.

Equity realisation, in plain words

Here is the part most players skip, and it is the part that costs money.

The 38.4% above assumed you get to see both the turn and the river. In a real hand you often do not. Your opponent bets the turn and now you must pay again, or fold and collect nothing at all from the equity you held. The share you actually bank is called your realised equity, and for most hands it is lower than the raw number.

Three things decide how much of your equity survives contact with the betting:

• Position. Acting last means you see what your opponent does before you commit. In position, a draw gets to take a cheap card far more often, so it keeps more of its share.
• How obvious your hand is when it arrives. A flush draw makes a hand everyone can see. A small pair that needs to stay the best hand with no improvement realises badly: you will be asked to pay three times to find out.
• Whether you can apply pressure. Hands that can raise realise more than hands that can only call, because folding out the other player banks the whole pot instead of your share of it.

This is why two hands with identical equity are not worth the same. Ace-four suited and king-jack offsuit can run within a point of each other against a button range preflop, yet the suited ace is worth more in practice, because it flops draws it can play aggressively and folds cheaply when it misses.

These are the reference points worth carrying in your head. Preflop rows are enumerated over every suit arrangement, so they match the figures in the textbooks; flop rows count all 990 turn-and-river combinations for the exact cards shown.

Four ways the word gets used

“Equity” shows up in a few phrases that mean related but distinct things. Quick translations:

• Raw equity or hot-and-cold equity — the number above, assuming all remaining cards get dealt with no more betting.
• Equity against a range — your share against every hand an opponent could hold, weighted by how likely each one is. This is the number that matters in practice, because nobody plays face up. The calculator’s vs-range mode gives it to you.
• Fold equity — the value that comes from your opponent folding, which raw equity ignores entirely. It is why betting a hand with 30% equity can beat checking it.
• Equity edge — loose table talk for “I am ahead here”. Harmless, but it is not a number.

How to actually get the number

1. At the table: count your outs and use the rule of 4 and 2. Nine outs with two cards to come is about 36%; with one card to come, about 18%. The poker odds chart has all of it on one printable page.
2. After the session: type the hand into the equity calculator. Compare the real answer with what you guessed in the moment. The gap is your study list.
3. Before the session: know which hands you are taking into these spots. That is what the preflop charts are for.
4. Over a month: remember that equity is an average, and averages need volume to show up. The variance calculator shows how wide the swings can be even when every decision was right.
