Poker Pot Odds Calculator

Turn the pot, the bet and your outs into a call-or-fold answer, and drill the decision until it's instant.

This prices one call against the money already in the pot, so the equity beside it has to be the equity of one call. Turn is that equity for a flop call, one card off the 47 unseen, and it is what the tool opens on. River is the same thing a street later, the last card alone off the 46 unseen once the turn is down. Turn + river is the right setting only when no further betting can happen, which on the flop usually means someone is already all-in.

Verdict

That is inside 5% of the 25 you are being asked for, which is the band where the drill below this calculator marks either answer right. The verdict is real, and at this price it is worth about 1.1 chips either way.

The same spot in the MDF and bluff ratio calculator is Pot 75, Bet 25. That page counts the pot before the bet goes in, so the figure it wants is not the one in this field.

Outs

You are calling one bet on the flop and only the turn comes for it. One card off the 47 you have not seen.

The turn is already down, so you are calling for the river alone. One card off the 46 cards left.

Both cards for one payment: the all-in or check-down reading. It reads too high for a flop call with a turn bet still behind it.

The idea

Pot odds are the price the pot is offering you to continue. If there is 100 in the pot and you must call 25, you are risking 25 to win 125, so you need to win at least 25 / 125 = 20% of the time for the call to break even. Compare that break-even number with your chance of improving and the decision makes itself.

Your chance of improving comes from your outs, the cards that make your hand.The quick estimate is the rule of two and four: multiply outs by two for one card to come, by four for two. The same out count reads differently depending on which card is still coming, sometimes by a lot, which the three-street table beside the calculator prices exactly rather than leaving to the shortcut alone.
One choice decides which of those three numbers belongs next to the price.The pot is quoting you a price for this bet, on this street, so the honest comparison is normally the single card that comes next. Two cards to come is the right reading only when there is no more betting to do, which usually means someone is already all-in. Carry the two-card figure into a flop call that still has a turn bet behind it and you will call far too often, since it is always the largest of the three readings. The calculator opens on that flop call, because it is the decision it is most often asked about.
When your raw equity falls short of the pot odds, implied odds can rescue the call: if you expect to win enough extra chips on later streets when you hit, a call that looks marginally negative now can be clearly correct. The tool shows how much more you would need to make on average.

FAQ

Questions players ask

How do I convert outs to a percentage?

With one card to come it is just your outs over the cards you have not seen: 47 of them from the flop, 46 from the turn. With two cards to come the chance of hitting at least one out is 1 − (non-outs choose 2) / (47 choose 2). The rule of four (outs × 4) tracks that closely up to about 8 outs, 32% against 31.5%, then drifts high: 48% against 45.0% at 12 outs, and 84% against 69.9% at the 21 this tool allows.

Should I use one card to come or two?

One, unless there is no betting left to do. The price in the pot is the price of this bet on this street, so it belongs beside the card that comes next. Two cards to come applies when you are calling all-in, or are otherwise certain to see both cards for this single payment. Which of the two one-card settings you want is a question about where you are sitting, not about the cards. Turn is a flop call, one card off the 47 unseen. River is a turn call, one card off the 46 left. At nine outs the two read 19.1% and 19.6%: a 0.4-point gap, small on its own, and still enough to flip the verdict at a price that lands between them, which is why the three-street table on this page prices Turn, River and Turn + river side by side instead of asking you to remember or re-check the other two.

What are implied odds?

The extra chips you expect to win on later streets when your draw completes. They let you call slightly unfavourable pot odds now because the true reward is larger than what is in the pot at the moment.

Do pot odds apply when I might be drawing dead?

Only if your outs are real. If some of your 'outs' also improve the opponent to a better hand, discount them. The calculator assumes the outs you enter are clean.

Methodology

How this is calculated

Two numbers, and a comparison between them. The price is call / (pot + call): with 100 in the pot and 25 to call you risk 25 to win the 125 that would be there, so 20% is break even, and the 4.0 : 1 printed beside it is that same price written as pot / call.

Your side of the comparison is exact combinatorics over the cards you have not seen rather than the shortcut, and there are three of them because there are three real spots: outs / 47 for a flop call with only the turn to come, outs / 46 for a turn call with only the river to come, and 1 − (47 − outs)(46 − outs) / (47 × 46) for both cards bought with one payment, which is one minus the chance of missing both.

Those three are three streets rather than three views of one, and the denominator is what separates them: 47 cards unseen from the flop, 46 from the turn. The verdict is the chip EV of calling rather than folding, equity × pot − (1 − equity) × call.

That expression is exactly zero at the break-even price, which is why the marker on the bar sits at the point the verdict flips. When it comes out negative, the implied-odds figure is the extra you would need to win on later streets to bring it back to zero.

Common misreadings4

A Call verdict at Turn + river is not a call you can make on the flop for one bet. The three-row table above prices the same outs, the same pot and the same call on all three streets side by side, and the Turn + river row is routinely a Call where the two one-card rows above it are not. Nothing about the cards changes between rows. What changes is a claim about the betting still to come, and it is only true when there is none: an all-in, or a hand both players check down.
A positive EV figure is not money you are about to collect. It is an average over every time this exact spot occurs, and a nine-out draw with one card to come misses about four times in five. The number grades the decision, not the hand in front of you.
A fast drill score is a fast arithmetic score. The drill hands you a clean out count and a fixed price, and gives partial credit inside 5% of the call for spots near the line. Counting outs correctly at a real table, against a range you cannot see, is the part it does not test.
Getting the price right is not an edge over the game. Pot odds settle whether one call costs less than folding does, and nothing in that comparison covers the rake taken from pots you win, the skill of the players you are calling, or the streets you play badly afterwards. A break-even call is break even, which is not a reason to go looking for more of them.

Assumptions5

Unseen means unseen by you. Every card you have not seen is equally likely to arrive, including the ones in opponents' hands: 47 unknown after the flop, 46 after the turn. That is the standard convention and it is the honest one, because a card sitting in someone else's hand is not a card you have information about.
Three settings, three streets, and the tool opens on the first of them. Turn is a flop call with only the turn to come, one card off the 47 unseen, and it is the default because it is the spot this page is most often opened for: someone facing a bet on the flop with a draw, working out whether the price is right. River is a turn call, one card off the 46 left. Turn + river runs both cards off the 47 unseen after the flop, and prices a single payment that buys both of them. Picking the wrong one of the three moves the answer further than any other input on this page, which is why the calculator now prices all three at once instead of asking you to remember or re-check the other two: compare your selected street's row against the other two in the table above the drill.
Every out is clean, and hitting one wins the whole pot. The arithmetic cannot know that a flush card pairs the board, that your straight card fills a bigger straight for someone else, or that the hand chops. Outs you are unsure of are yours to discount before you type them in.
The pot and the bet are what is on the table now. Chips you put in earlier in the hand already belong to the pot rather than to the price of continuing, and rake is not taken out of either figure.
Turn + river is the chance of improving by the river, and it assumes you see both of those cards for the single bet in the Bet to call field. That holds when the money is already in, or when the hand is checked down. It does not hold in an ordinary betting sequence, where the turn brings another bet you have not been quoted yet. The line under the control says so while the setting is selected, because a setting whose validity condition is invisible is how a flop caller ends up reading a 35.0% off a 20% price.

Limits4

This is chip EV, not tournament EV. Chips won and chips lost are not worth the same amount in a tournament, so a call that is correct here can be clearly wrong on a bubble or at a final table. The ICM calculator is where that difference gets priced.
One street, one decision. Nothing after the call is modeled: not the bet you will face on the river, not the hands where you improve and are still behind, and not the times you end up folding the best hand later.
The implied-odds number is a requirement, not a forecast. It says how much more the call would have to win on later streets, and it assumes that money arrives exactly when you hit and costs nothing when you miss. Whether the opponent holds it, and would pay it, is a read, and this tool has no way to make one.
The rule of 2 and 4 is printed for comparison, and its error runs one way in each direction. Doubling the outs understates, because one card is worth a little more than 2%: 2.13% off the flop, where 47 cards are unseen, and 2.17% off the turn, where 46 are. Multiplying by four overstates, and the gap widens with the size of the draw: 8 outs is 32% against 31.5% exact, 12 outs is 48% against 45.0%, and at the 21 outs the field allows it is 84% against 69.9%.

Evidence

The four functions are in math.ts and math.test.ts covers each of them: the exact draw equities against the standard published figures for a flush draw (35.0%), an open-ender (31.5%) and a gutshot (16.5%); the one-card figures pinned directly to outs / 47 and outs / 46, which are the assertions fixing the Turn setting to the flop and the River setting to the turn, and a third that holds the three settings distinct and in street order so that adding one cannot quietly move the other two; that the shipped defaults fold on Turn and River and call on Turn + river, which is the behavior the misuse note above describes; the identity that the R : 1 and the break-even percentage are two views of one number, equity = 1 / (R + 1), checked across eight pot and call pairs; that chip EV is exactly zero at the break-even price; and that winning the pot plus the implied-odds figure brings a losing call back to zero.

The identity test exists because that relation once failed in public. From this tool's first commit until a health check found it on 2026-09-07, the ratio was computed as (pot + call) / call, so the page printed 5.0 : 1 next to a 20% break-even (issue #160).

A passing test means the code computes the model described here, not that the outs you entered are clean.
