What it prices
Pot odds = the price of the call
You risk a fixed call to win a known pot. The break-even win rate is that call divided by the final pot after you put the chips in.

Pot odds
3∶1
$50 risked to win $100 + $50 → 25% break-even (3∶1).
The price
Required equity = call ÷ final pot
Final pot means pot before the bet, plus the bet, plus your call. A $50 call into a $100 pot with a $50 bet needs 50 ÷ 200 = 25% — the same as 3:1 pot odds.
Pot before
Blinds, limps, and earlier streets already in the middle.
Add the bet
Opponent’s wager sits on top of that pot.
Divide by call
Your cost ÷ (pot + bet + call) is the break-even win rate.

Break-even equity by bet size
At the table you see “half pot,” not ratios. These anchors assume you call the bet heads-up with no prior commitment.

| 1/4 pot | 16.67% |
| 1/3 pot | 20.00% |
| 1/2 pot | 25.00% |
| 2/3 pot | 28.57% |

| 1.5× pot | 37.50% |

Outs → equity
Exact hit % for common draws
Assumes clean outs and a 52-card deck with five known cards on the flop (47 unseen). Rule of 2/4 is the mental shortcut — slightly high above ~10 outs.
| Outs | Draw | Next card | By river | ×2 / ×4 |
|---|---|---|---|---|
| 2 | Pocket pair → set | 4.3% | 8.4% | 4% / 8% |
| 4 | Gutshot straight | 8.5% | 16.5% | 8% / 16% |
| 6 | Two overcards | 12.8% | 24.1% | 12% / 24% |
| 8 | Open-ended straight | 17.0% | 31.5% | 16% / 32% |
| 9 | Flush draw | 19.1% | 35.0% | 18% / 36% |
| 12 | Flush + gutshot | 25.5% | 45.0% | 24% / 48% |
| 15 | Flush + open-ender | 31.9% | 54.1% | 30% / 60% |
Beyond the pot
Implied and reverse-implied odds
Immediate pot odds price this street only. Future money can justify a call that looks short — or punish a “cheap” call when you get paid only when you lose.
Implied odds
You expect to win extra chips on later streets when you hit. A turn flush draw short of 25% can still call if the river stacks you will extract cover the gap.
Reverse-implied odds
You hit and still lose bigger pots — non-nut flush, weak two pair, underfull. Discount dirty outs; the “cheap” call becomes expensive when the nut hand stacks you.
This calculator stops at the pot
It does not invent future bets or stack sizes. Use required equity as the floor; add implied math only when you can name who pays and how much.
Worked spots
Same draw, opposite prices
Turn flush draw vs half pot — fold on price alone
Pot $100, bet $50. You need 25%. Nine hearts hit the river 9/46 ≈ 19.6%. Below the price → fold unless future money (implied odds) clearly covers the gap.
Flop flush draw all-in vs pot — thin call
Pot $100, opponent shoves $100. You need 33.3%. Nine outs by the river ≈ 35.0%. Both cards are paid — the ×4 shortcut (36%) is the right street frame.
Facing a raise — only the extra chips are your call
You bet $60 into $90; opponent raises to $180. Your call is $120 into a pot that already holds $330. Required: 120 ÷ 450 = 26.7%. Dead money you already put in improves the price; it is not part of the cost.
Open-ender vs third pot — clear on next card
Pot $90, bet $30. Call $30 needs 20%. Eight outs on the turn ≈ 17.0% (8/47) — still short for one card. If the bet is all-in for both cards, eight outs ≈ 31.5% clears the 20% price.
Gutshot vs tiny bet — still a fold without implieds
Pot $80, bet $20 (¼ pot). You need 16.7%. Four outs next card ≈ 8.5%. Price alone says fold; only deep stacks and a clear pay-off plan change that.
Leaks
Common pot-odds mistakes
Counting dirty outs at full value
A card that completes your flush and a higher flush (or a full house) is not a clean out. Discount it.
Using outs × 4 while another bet is coming
The four-times shortcut assumes both remaining cards are free. Facing a flop bet with a turn bet likely, price the next card (×2 / 47-card math).
Adding your earlier bet into the cost
Chips you already committed belong to the pot. Only the amount still required to call goes in the cost column.
Ignoring players behind
A heads-up price can vanish if a raise behind is likely. Recalculate if the action changes.
Calling “because pot odds” with no equity estimate
The price alone never says call. You still need a realistic win rate — outs, or a range read — to compare against it.
Terms
Pot odds vocabulary
Same words show up on training sites with different formulas. These are the definitions this calculator uses.
- Required equity
- Break-even win rate for this call: call ÷ (pot before + bet + call).
- Pot odds (ratio)
- How many chips you can win before your call, per chip you put in — e.g. 3:1 means you risk 1 to win 3.
- Outs
- Unseen cards that improve you to the likely winner. Clean outs exclude cards that also complete a better hand for someone else.
- Rule of 2 and 4
- Mental shortcut: outs × 2 for one card, outs × 4 when both turn and river are coming and already paid.
- Equity
- How often your hand wins against the opponent’s range. Pot odds set the price; equity is what you bring.
Frequently asked questions
How do you calculate pot odds in poker?
Divide the amount you must call by the pot after you call: call ÷ (pot before + bet + call). Facing $50 into a $100 pot, you need 50 ÷ 200 = 25% equity to break even — also written as 3:1 pot odds.
What does 3 to 1 pot odds mean?
You can win three chips for every one chip you call. Required equity is 1 ÷ (3 + 1) = 25%. Half-pot bets create that price heads-up.
What pot odds do I need for a flush draw?
A flush draw has 9 outs. Next card ≈ 19.1% (9/47); by the river with both cards paid ≈ 35.0%. Compare that to the required equity from the bet size — a half-pot bet needs 25%, so a turn call is short on immediate price; an all-in for both cards can clear a pot-sized price.
How many outs does an open-ended straight draw have?
Eight clean outs (four ranks on each end). Next card ≈ 17.0%; both cards ≈ 31.5%. That is why open-enders need a cheaper price than flush draws on a single street.
Should I call a gutshot with pot odds alone?
Usually no. Four outs hit next card ≈ 8.5%. Even a quarter-pot bet needs about 16.7%. A gutshot needs strong implied odds or a multiway price to justify a call on math alone.
What is the Rule of 2 and 4?
Mental shortcut: outs × 2 for one card to come, outs × 4 when both turn and river are coming. Nine outs ≈ 18% / 36% versus exact 19.1% / 35.0%. Use ×4 only when no further bet must be called.
What is the difference between pot odds and equity?
Pot odds (required equity) are the price of the call. Equity is how often your hand wins. Call when equity beats the price on that street — unless implied odds or other factors change the picture.
What are implied odds in poker?
Extra chips you expect to win on later streets when you hit. They can justify a call that is short on immediate pot odds — only when you can name who pays and roughly how much. This calculator does not invent that future money.
Do pot odds work the same in a multiway pot?
The formula is identical — more callers usually mean a better price. Your equity often drops against several ranges, especially with non-nut draws.
Does this calculator use hand ranges or Monte Carlo?
No. It only does break-even arithmetic on the chips you enter, plus exact combinatorial outs math when you optionally enter outs. Range equity tools are a different product.
