How to Calculate Pot Odds

Pot odds turn the price of a call into the minimum equity your hand needs. Divide the call amount by the final pot after calling (required equity = call amount ÷ final pot). Compare that percentage with your estimated equity to find the break-even point.

Example 1: Half-pot bet

The pot is $100 and your opponent bets $50. You call $50 to win a final pot of $200, so you need 25% equity. A flush draw on the turn has about 19.1% equity to hit on the river, so the immediate pot odds alone do not justify the call.

Example 2: Quarter-pot bet

The pot is $100 and your opponent bets $25. Calling $25 makes the final pot $150, so you need 16.7% equity. A clean nine-out flush draw has about 19.1% equity with one card to come, which clears the break-even point.

FAQ

Is the pot odds calculator free?: Yes. This pot odds calculator is free and works without an account.
What is the difference between pot odds and equity?: Pot odds (required equity) are the minimum win rate needed to call; equity is your actual chance to win. If equity beats required equity, calling is a candidate.
What are implied odds?: Odds that include extra money you can win after your draw hits. Use them when future bets matter beyond the current pot.
Can I calculate odds against a raise?: Yes. Switch bet type to raise and enter the opponent's raise size.
How do you calculate pot odds in poker?: Divide the amount you must call by the final pot after your call. For example, if the pot is $100 and an opponent bets $50, calling $50 creates a $200 final pot. The required equity is $50 ÷ $200 = 25%.
Should I call with a flush draw?: A nine-out flush draw hits about 19.1% of the time with one card to come and 35.0% with two cards to come. Compare that estimate with the calculator's required equity, then account for whether your outs are clean and whether future betting remains.
