Pot Odds & Equity Calculator
Use this tool to compare the price of a call with your chance to win. Enter pot size, call amount, and outs to get an instant call/fold guide.
What Are Poker Pot Odds?
Pot odds tell you whether a call is mathematically profitable in the long run. You compare:
- Price of the call (what you must invest now)
- Reward (what you can win from the pot)
If your chance of winning the hand is higher than the break-even percentage required by the pot, calling is generally correct.
The Core Formula
Break-even equity = Call ÷ (Pot + Call)
Example: If the pot is 80 and your opponent bets 20, you call 20 to win a final pot of 100.
- Break-even equity =
20 / 100 = 20% - If your equity is above 20%, call is profitable over time.
How This Calculator Works
- Enter the current pot size before your call.
- Enter how much you need to call.
- Add your outs and choose whether one or two cards remain.
- Optionally enter your own equity estimate from reads, ranges, or solver work.
- Review pot odds %, estimated equity, and expected value (EV).
Outs-Based Equity Method
This page uses exact draw math from unseen cards:
- 1 card to come:
outs / 46 - 2 cards to come:
1 - C(47-outs,2) / C(47,2)
That is more accurate than the quick “Rule of 2 and 4,” which is useful at the table but approximate.
Quick Practical Examples
Example 1: Flush Draw on the Turn
You have 9 outs with one card to come. Pot is 60, call is 20.
- Pot odds needed:
20 / 80 = 25% - Equity from outs:
9 / 46 ≈ 19.57% - Result: Purely by pot odds, this is a fold unless implied odds justify a call.
Example 2: Open-Ended Straight Draw on the Flop
You have 8 outs with two cards to come. Pot is 50, call is 10.
- Pot odds needed:
10 / 60 = 16.67% - Equity from outs by river: roughly 31.45%
- Result: Calling is strongly profitable.
Pot Odds vs Implied Odds
Pot odds use only the current pot. Implied odds include potential future chips you can win when your draw hits. In deep-stack games, implied odds can turn a borderline fold into a profitable call.
However, remember reverse implied odds: sometimes you hit and still lose to a better hand. Nut potential matters.
Common Mistakes to Avoid
- Counting dirty outs (cards that improve you but may improve villain more).
- Ignoring position and future action.
- Overcalling with weak draws out of position.
- Using only pot odds in multiway pots without range awareness.
- Assuming all outs are live against strong made hands.
FAQ
Is this enough to beat poker?
No single tool is enough, but pot odds are a foundational skill. Combine this with hand reading, position, bet sizing, and exploitative adjustments.
Should I always follow the calculator?
Use it as a baseline. In real games, player tendencies, stack depth, and future betting can change the optimal decision.
Can I use this for tournaments and cash games?
Yes. The math is the same, though tournament ICM pressure can alter practical decisions in late stages.
