Pot Odds and Expected Value

01How to Calculate the Equity Needed to Call

The “total pot after calling” includes the original pot, your opponent's bet, and the chips you are about to call with. Any chips you have already put in during the current betting round are counted as part of the pot.

Here, we assume there is one opponent and no further betting after you call. In the table below, “pot” means the pot size before your opponent bets.

“3 to 1” and “25%” Use Different Denominators

When pot odds are expressed as a ratio, you compare the current pot with the call amount. When the equity needed is expressed as a percentage, you divide by the pot after including your call.

Reading 3 to 1 as 33.3% is a mistake. You only need to win once in four attempts, so the figure is 25%.

02Win Frequency and Payoff Size Are Different

Expected value is the average amount you gain or lose per attempt if the same situation is repeated many times. It does not predict the result of a single hand.

An opponent bets 50 into a pot of 100, and you call 50. If your chance of winning is 30%, the result is as follows.

+10 does not mean you will gain 10 on that hand. You gain 150 when you win and lose 50 when you lose. +10 is the average weighted by how likely each result is.

If your chance of winning equals the required 25%, the expected value is 0. Even if you lose more often than you win, a cheap call that can win a large pot may have positive expected value.

This calculation applies directly only when no betting remains. Examples include calling on the river when you act last, or calling an all-in against one opponent. If a tie is possible, include your share of a split pot in your equity.

0335% by the River Does Not Always Mean You Can Call Now

With 9 outs on the flop, the chance of hitting by the river is 35.0%. The chance of hitting on the next card alone is 19.1%. Both figures are drawing probabilities and are not necessarily the same as your chance of winning.

You can compare the current call amount directly with 35.0% only when you will see both the turn and river without putting in any more chips. One example is when a single opponent goes all-in on the flop.

If your opponent still has chips, they may bet again on the turn. You would then need to call again to see the river. Comparing 35.0% with only the current call amount leaves out the chips you may have to pay later.

Probabilities for different numbers of outs are listed in the quick probability chart.

04Future Payoffs and Outs That Still Lose

If you expect to win more chips from your opponent after completing your draw, you can account for those chips as well. This is called implied odds.

Even when the current pot odds fall slightly short, a call may have positive expected value if your opponent is likely to pay you off after you hit. However, if your opponent folds, you get no additional chips. You cannot treat that future amount as certain.

• When you act later, you can see what your opponent does after you hit before choosing your bet size.
• An obvious draw, such as a flush draw, may not get paid after it comes in.
• If your opponent has a short stack, the amount you can win later is limited.

Conversely, some cards complete your draw but still leave you behind. You may make a low flush and lose to a higher flush. A card that completes your straight may also complete your opponent's flush.

You may also put in more chips after hitting and still lose. That potential loss matters too. Counting all such cards as full outs overestimates your chance of winning. See how to count outs for more details.

05Multiway Pots and Side Pots

No matter how many opponents are involved, the formula stays the same: divide the call amount by the total pot after calling. If more chips from other players are already in the pot, the equity needed to call is lower.

However, the equity you compare it with must be your equity against every player still in the hand. If even one player among those contesting a pot beats you, you do not win that pot.

If players are still left to act behind you, one of them may raise. If that happens, recalculate both the call amount and the pot.

Count Only the Pots You Can Win

When players go all-in for different amounts, the chips are divided into a main pot and one or more side pots. You cannot win a side pot you did not contribute to.

Calculate the equity needed using only the pots you are eligible to win. Including every chip on the table makes the required equity look too low. If different opponents contest the main pot and a side pot, consider your opponents and equity separately for each pot. See all-ins and side pots for how the pots are divided.

06Common Mistakes

• Calling to recover chips you have already put in. Compare the amount you must pay now with the amount you can win from this point forward.

You compare your equity with the required equity when considering a call. If you raise, you must also account for the chance that your opponent folds. See how to choose a bet size for more details.

08Try It in BlackPoker

In BlackPoker, the win odds needed to call appear below the Call button. From the flop onward, the game also shows win odds based on the opponent’s actions, letting you compare the two figures.

These win odds are estimated by dealing out cards repeatedly, so the result may vary by 1–2% even in the same situation.
