How pot odds work
Pot odds compare the price of a call with the size of the prize. If the pot is $100 and your opponent bets $50, you must pay $50 to win $150 (the pot plus the bet). The final pot after your call is $200, so you are risking $50 of it. Your break-even equity is 50 / 200 = 25%.
That 25% is the share of the time you must win the hand for calling to cost nothing in the long run. If your real chance is higher, the call makes money; if it is lower, it loses money. The same price is often written as odds: $150 to win against $50 to pay is 3 to 1.
With a draw, count your outs, the unseen cards that complete the hand. On the flop 47 cards are unseen. With 9 flush outs the exact chance to hit on the turn alone is 9 / 46, about 19.6%, and to hit by the river about 35.0%. The rule of 4 gives 36% and the rule of 2 gives 18%, quick estimates that overshoot slightly with many outs.
Worked example
You hold a flush draw on the flop (9 outs). The pot is $100 and your opponent bets $50. You need 25% equity.
If you will see only the turn, you hit 19.6% of the time, below 25%, so pure odds say fold. If the money goes in now and both cards come, you hit about 35.0%, above 25%, so the call is profitable. This is why the number of cards still to come, and the chance of facing another bet, matters as much as the outs.
Questions and answers
What are pot odds in poker?
Pot odds are the ratio between the current pot (including your opponent's bet) and the cost of your call. They tell you how often you must win for a call to break even.
How do I calculate the equity I need?
Divide the bet you must call by the final pot after your call: bet / (pot + 2 × bet). For a $50 bet into a $100 pot that is 50 / 200 = 25%.
What is the rule of 2 and 4?
A shortcut for hit chances: multiply your outs by 2 for one card to come, or by 4 with two cards to come on the flop. It is quick but slightly high when you have many outs; the calculator also shows the exact figures.
Do pot odds include implied odds?
No. Pot odds look only at the money in the pot now. Implied odds add the money you expect to win on later streets and can justify a call that pure odds reject.
