Pot odds

In poker, pot odds express the reward the pot offers relative to the price of calling a bet, helping a player decide whether the call is mathematically worthwhile.

Formula
Pot size ÷ cost to call
Example
$40 pot, $10 to call = 4-to-1 pot odds2
Use
Compare pot odds to your chance of winning; call if the chance is better than the price offered13
Applies to
Poker, especially Texas hold 'em betting rounds14

Key points

  • Pot odds are the price the pot offers for a call, expressed as a ratio like 4-to-1.2
  • A player compares pot odds to the odds of completing a drawing hand; if the draw odds are better, calling is profitable.13
  • Unlike implied odds, pot odds consider only the current pot, not future chips that might be won.5
  • Raising can change the pot odds for opponents, altering their decision to call or fold.1

Pot odds example

You face a $10 call into a $40 pot, giving pot odds of 4-to-1. If you are on a flush draw with roughly 4-to-1 odds of hitting on the next card, calling is break-even or better. If the draw odds are worse than 4-to-1, folding is mathematically correct.23

Common questions

What are pot odds in poker?

Pot odds are the ratio of the current pot size to the cost of a call. They help you decide whether calling is mathematically justified based on your chance of winning.

What are good pot odds?

Good pot odds mean the pot is offering a high ratio relative to the call cost, making it profitable to call if your chance of winning is better than that ratio. For example, 4-to-1 is good if your draw has a 20% or better chance of hitting.

How to calculate pot odds?

Divide the current pot size by the cost to call. For a $40 pot and a $10 call, pot odds are 40 ÷ 10 = 4, expressed as 4-to-1. Then compare that to your odds of winning the hand.
