Pot odds: how to tell if a call is worth it
Updated November 2026
Pot odds tell you how often you have to win for a call to break even. Take what you have to pay and divide it by everything that will be in the pot once you've paid: a $50 call into a pot that ends up at $200 needs to win 1 time in 4.
You don't need to be good at math for this. If you can count stacks of chips you can price any bet in poker, and the stacks below will do it with you the first few times. Pick a bet size and count.
What are pot odds, in plain English?
Think of the pot as a raffle. Your call is the ticket and the prize is all the money in the middle once your ticket has gone in.
Pay $50 for a shot at $200 and you've bought a quarter of the prize, so you need to win a quarter of the time.
Win more often than that and the call makes money over time; win less often and you're overpaying for the ticket.
Pot odds are only the price, though. You still have to work out whether your hand is good enough to pay it, and we'll get to that.
The same $50 ticket
On this page "the pot" always means the money in the middle before his bet.
How do I work out pot odds at the table?
There are two ways, and after a few weeks most players only use the second.
The long way uses dollars. Add the pot, his bet and your call, then divide your call by the total. Say the pot is $100, he bets $50 and you have to call $50:
The short way uses stacks, the same ones you just counted. A half-pot bet means the pot is 2 stacks, his bet is 1 and your call is 1. Four stacks, one of them yours, so 1 in 4.
Learn these four and you've got most bets covered:
Look how slowly that number moves. Double the bet from half pot to full pot and you only go from 1 in 4 to 1 in 3, which surprises a lot of people the first time they see it.
Big bets feel far more expensive than they are, and that's a good part of why they work.
Can I plug in my own numbers?
Yes. Type in the pot and the bet. If you're on a draw, set your outs (the cards that would make your hand) and it will compare the price with your real chance of hitting.
What does "3 to 1" mean?
Older books and older players quote pot odds as a ratio. With $150 out there to win and $50 to pay, you're getting $150 to $50, or 3 to 1.
To turn a ratio into a chance, add the two numbers together and put the second one on top:
It's the same price written differently, so use whichever you find easier.
Why does 1 in 4 break even?
Because the wins and the losses cancel out to the dollar. Play that $50 call 100 times.
Average profit of a call = (chance you win × what you win) − (chance you lose × what you pay)
Players call that number EV, short for expected value: what a decision makes on average if you could repeat it forever.
0.30 × $150 − 0.70 × $500.20 × $150 − 0.80 × $50Why do good calls lose so often?
Because the price can be right while the odds are still against you. You hold the jack and ten of hearts on this board, and he has a pair of kings, so only a heart saves you.
Two hearts are in your hand and two are on the board, which leaves 9 among the 46 cards you can't see. You hit 9 times in 46, about 1 in 5.
One river card, 100 times
Gold dots are the hearts you hit
If he bets $25 into $100 and that's the last money to go in, the price is 1 in 6. That's a good call, worth about $4.35 every time you make it, and it still loses 80 times out of 100.
So a short stretch of results tells you very little. Here's how often you'd be ahead:
Bad calls hide just as well. Call a half-pot bet with this same hand and you'll still be in profit after 10 tries 31% of the time, even though each of those calls loses about $10.87 on average.
What the bet size does to this call
Average profit of calling with a flush draw on the turn, pot $100
Deal it yourself and watch the line wander around the dotted one.
Judge the call by the price you got, and never by the card that came.
When the guy who called off with a gutshot hits and rakes in the pot, he still made a bad call. The bill just comes later.
How do I know my chance of winning?
When you're on a draw you count outs: the cards still in the deck that turn your hand into the winner. These are the three draws you'll see most.
Flush draw: 9 outs
Four cards of one suit, one more needed. It hits 20 times in 100 with one card to come and 35 in 100 with two.
Open-ended straight draw: 8 outs
Four in a row, open at both ends. It hits about 17 times in 100 with one card to come and about 31 with two.
Gutshot: 4 outs
A straight with one card missing from the middle. It hits about 9 times in 100 with one card to come and about 16 with two.
Nobody at the table does long division, so use the shortcut. With one card to come, multiply your outs by 2; with two cards to come, multiply by 4.
The shortcut stays close while you have few outs, but at 15 outs the ×4 rule says 60% and the truth is 54.1%, so shave a few points off big draws.
What if I have a made hand and nothing to count?
Then turn the question round and ask how often he's bluffing. This comes up most on the river, when there are no cards left. Say the pot is $100 and he bets $75.
If your hand beats only a bluff, ask yourself one thing: does this player bluff here 3 times in 10?
Against someone who hasn't shown you a bluff all night, probably not, and the fold is easy. Against a player who can't stop firing, the same hand is a call.
Either way you now have a number to hold your read up against, and that beats a gut feeling.
Can I use the two-card number on the flop?
Only if no more money can go in. Every card room has a player who calls any flush draw at any price, and this is the sum he never did.
You have that flush draw on the flop, the pot is $100 and he bets $50, so you need 25%. The shortcut says you have 36% and it looks like an easy call.
Flush draw on the flop
But 35% is your chance across two cards, and you only get to see both if he lets you.
0.35 × $150 − 0.65 × $500.191 × $150 − 0.809 × $50You fold when you miss because the price tells you to: $100 into $200 needs 25% and you'd have 19.6%. So you really had one card, which is 9 outs in 47 cards, or 19.1%.
Same cards, same bet, and it's worth +$20 or −$12 depending on what happens next.
So with more betting to come, use the one-card number.
What can rescue the call is money you haven't won yet, and that has its own name.
What are implied odds?
Implied odds count the money you expect to win after you hit. When the flush lands he may keep betting or pay off your bet, so the real prize is bigger than what's in the middle now.
The catch is you have to put a number on it, and it's usually bigger than people think. Pick a draw and see.
A gutshot facing a half-pot bet on the turn is the classic case. You hit 8.7% of the time, so each time you do, you need another $375 out of him on a $100 pot.
If he only has $100 left, no amount of wishful thinking gets you there. Deep stacks and opponents who hate folding make implied odds real. Short stacks and careful players take them away.
Gutshot, half-pot bet, $100 pot
There's an ugly cousin called reverse implied odds, where making your hand costs you more. Hit a small flush into a bigger one and you'll pay off every bet he makes.
Outs like that are dirty outs, and you should knock them off your count: on a paired board, for instance, your flush can run straight into a full house.
Does the rake change the math?
Yes, and small pots feel it most. The rake is the cut the house takes out of the pot, so divide your call by what's left after it. Say the house takes 10% up to a $10 maximum.
10% of a small pot, $40
What the rake adds to the price
Half-pot bet, house takes 10% up to $10
That's why loose calls in small pots cost more than they seem to.
What about raises and three-way pots?
With a raise, count only what you still have to pay. You bet $20 into $40 and he raises to $60.
The $20 you already put in belongs to the pot now.
With other players still to act, the price you see might not be the final one, because someone behind you can raise and make you fold after you've paid.
If several players have already called, the pot is bigger and the price is better. Your chance changes too: one pair is a lot weaker against three hands than against one, while a flush draw that hits is still good against all of them.
Can you do it without looking?
Twelve spots in three rounds. Get one wrong and you'll see exactly why.
Questions players ask about pot odds
What are good pot odds?
No price is good on its own. A 1-in-6 price is great with a flush draw and terrible with a hand that can't win, so always compare the price with your chance.
Are pot odds the same as equity?
No. Pot odds are the price. Equity is your share of the pot: what you'd win on average if the hand were played to the end with no more betting. You call when your equity is bigger than the price.
Do pot odds work before the flop?
Yes, and the big blind is where you'll use them most. The button raises to 2.5 big blinds and the small blind folds. You already have 1 big blind in, so you pay 1.5 more for a final pot of 5.5: 1.5 / 5.5 = 27.3%.
That cheap price is the reason you can defend the big blind with hands you'd fold from any other seat.
Do pot odds work in tournaments?
The sum is the same. What changes is the value of the chips: near the prize money, the chips you could lose are worth more than the chips you could win, so you need a better price than the math suggests.
Should I always fold when the price is wrong?
Not if you have implied odds or you plan to raise. Pot odds price a call and nothing else.
How the numbers on this page were worked out
Chances come from counting cards. With one card to come there are 46 you can't see (52 minus your 2 and the 4 on the board), so the chance is outs / 46.
With two cards to come from the flop it's 1 − (47 − outs) / 47 × (46 − outs) / 46. For the flush draw you can check that by listing all 1,081 possible turn and river pairs: 378 of them contain a heart, which is 34.97%.
The figures for how often you're ahead after 10, 100 and 500 calls come from the exact binomial formula. The average itself is expected value, and the reason results settle down over many tries is the law of large numbers.
