Pot odds compare what a decision costs with what success pays and how likely success is. Boeree illustrates the calculation with a poker draw: if nine of 36 remaining cards complete a flush, the success probability is 25 percent. If the pot offers five-to-one on the required call, the payoff exceeds the odds needed to hit the card, making the call profitable in expected-value terms. The rule does not promise that any single attempt will win. It identifies whether the reward is large enough for the risk across repeated comparable decisions. The same structure applies whenever a decision-maker can estimate downside, upside, and the probability of obtaining the desired outcome.
Origin
Boeree explains pot odds while outlining the rudimentary mental calculations a poker student must learn.
Core principles
- 01Judge upside relative to the amount at risk
- 02Estimate success from the remaining favorable outcomes
- 03Accept positive expected-value opportunities despite possible loss
- 04Use comparable ratios before committing resources
How to run it
- 1
Measure the stake
Identify exactly how much must be committed to continue.
Pro tip Use the incremental amount at risk, not money already committed.
Watch out Sunk costs should not inflate the current stake.
- 2
Estimate success
Count favorable outcomes and divide by the relevant remaining possibilities.
Pro tip State uncertainty when the possibilities are only estimates.
Watch out An unsupported probability makes the comparison cosmetic.
- 3
Calculate the offered payoff
Compare the amount available to win with the amount required to continue.
Pro tip Express the result as a ratio that can be compared with the success odds.
Watch out Do not count an advertised upside that cannot actually be captured.
- 4
Make the expected-value choice
Proceed when the offered payoff is greater than the odds required by the probability of success.
Watch out A profitable decision can still lose on a single trial.
In the wild
Boeree gives a case with nine helpful cards among 36 remaining cards, creating a 25 percent chance of success. When the pot offers five-to-one, the potential payoff is greater than the odds required to hit the flush.
→ The call is profitable on an expected-value basis even though failure remains possible.
Common mistakes
Treating a good bet as a guaranteed win
Expected value describes repeated outcomes, not certainty on the next attempt.
Comparing payoff without probability
A large upside is not attractive unless its likelihood justifies the amount at risk.
Is it for you?
Best for
Repeated decisions with an estimable success probability, known amount at risk, and measurable payoff.
Not ideal for
One-off choices whose outcomes, probabilities, or non-financial consequences cannot be estimated credibly.
