Poker Odds Calculator

Poker hand odds are the probability of completing a drawing hand by the next card (the turn) or by the end of the hand (the river). They are calculated from the number of "outs" - unseen cards in the deck that complete your hand. For example, with a four-card flush draw, you have 9 outs (remaining cards of your suit). On the flop with two cards to come, the approximate probability of hitting at least one is 9 times 2 times 2, which equals 36%, using the rule of 2 and 4.

Pot odds are the ratio of the current pot size to the cost of calling a bet. If the pot is $100 and you must call $25, your pot odds are 100 to 25, which simplifies to 4 to 1, or 20%. If your probability of winning (based on outs) is greater than 20%, calling is mathematically profitable in the long run. Pot odds help you decide whether a call has positive expected value. Learning to compare pot odds to hand odds is a foundational poker skill.

Equity is your probability of winning the hand at any given point, expressed as a percentage. If you have a 35% chance of winning, you have 35% equity in the pot. Equity changes as community cards are revealed. Knowing your equity against a range of opponent hands (not just a specific hand) is more realistic and requires tools like equity calculators or practice with range analysis. This calculator provides single-hand equity estimates based on the cards you input.

Implied odds extend pot odds to account for the additional chips you expect to win on future streets if you hit your draw. If calling a bet is not profitable based on pot odds alone but you expect to win a large pot if you complete your hand, implied odds can justify the call. Implied odds are highest when your opponent has a deep stack, is likely to continue betting with a strong hand, and your draw is well-disguised (such as a low set or a backdoor draw). They are difficult to quantify precisely and require judgment.
