Pot odds in one page
How to price a call in under a minute—and when the math lies because another bet is coming.

- basics
Pot odds answer one question: “If I call now and the hand ended, am I getting the right price?” They ignore implied odds and future streets until you add those back by hand.
The formula
Equity you need ≈ call amount ÷ final pot including your call.
Example: the pot is $80 and villain bets $40. You risk $40 to win what will be $80 + $40 + $40 = $160.
You need 40 / 160 = 25% equity if no more money goes in.
Pair it with outs
On one street to come, multiply outs by 2 (turn to river) or 4 (flop to river) for a rough percentage, then compare to the number above. Flush draw with nine clean outs is ~35% flop-to-river by the rule of 4—often enough to continue against a small bet; not always enough against a jam if you will face another barrel when you miss.
When pot odds steer you wrong
- Hidden reverse implied odds: you hit your draw but lose stacks to a higher flush or full house.
- Position: out of position, your “correct” call on the flop may commit you to bad turn decisions.
- Multiway pots: someone behind you can raise; tighten up unless you have a clear plan.
