Poker Pot Odds Calculator
Determine whether calling a bet is profitable by comparing pot odds to your win probability, including expected future bets. Use it any time you face a call on the flop, turn, or river.
About this calculator
Pot odds measure the ratio of the amount you must call to the total pot you stand to win, expressed as a required equity percentage. The break-even equity needed to call is: Required Equity = betToCall / (potSize + betToCall). Implied odds extend this concept by adding the extra chips you expect to win on future streets if you complete your draw: Effective Pot = potSize + betToCall + impliedOdds. This calculator goes further and computes your expected value (EV) of calling: EV = (effectivePot × winProbability) − betToCall, where winProbability is expressed as a decimal. A positive EV means calling is profitable over the long run. Negative EV means folding (or raising as a bluff) is preferable. Mastering pot odds and implied odds is foundational to beating any limit or no-limit poker game.
How to use
The pot is $100, your opponent bets $50, your win probability is 30%, and you expect $60 in future bets if you hit your draw. BetToCall = $50, effectivePot = $100 + $50 + $60 = $210. EV = ($210 × 0.30) − $50 = $63 − $50 = +$13. Because EV is positive, calling is the correct play. Without implied odds (impliedOdds = $0), effectivePot = $150 and EV = ($150 × 0.30) − $50 = $45 − $50 = −$5, meaning a fold would be correct — showing how implied odds can flip the decision.
Frequently asked questions
How do I calculate pot odds quickly at the poker table?
At the table, use this quick method: divide the bet size by (pot + bet) to get the fraction of the pot you are paying, then convert to a percentage. If the pot is $80 and the bet is $20, you pay 20 / (80 + 20) = 20%, meaning you need at least 20% equity to break even. Compare that to your estimated win probability using the rule of 2 and 4 for your outs. If your equity exceeds the pot odds percentage, calling has positive expected value. Practice this mental arithmetic until it becomes automatic.
What are implied odds in poker and how do they change my decision?
Implied odds represent the additional chips you expect to win on future streets if your drawing hand completes. They are not guaranteed — they depend on your opponent's tendencies, stack sizes, and board texture. For hidden draws like sets or straights on paired boards, implied odds are high because opponents will often pay you off. For obvious draws like a flush completing on a wet board, implied odds are low because opponents may check-fold. Always estimate implied odds conservatively; beginners routinely overestimate them, leading to unprofitable calls.
What is the difference between pot odds and expected value in poker?
Pot odds give you the break-even equity threshold — the minimum win probability needed to make a call not lose money over time. Expected value (EV) goes further and tells you exactly how much you profit or lose on average per call, in dollar terms. Pot odds are a quick filter: if your equity is below the pot odds threshold, EV is negative. If above, EV is positive. The EV calculation, which this calculator provides, is more useful for comparing close spots or sizing bets, because it quantifies the magnitude of the edge rather than just its direction.
