Pot Odds
The ratio of the current pot size to the cost of a call, used to decide whether a call can be profitable.
Definition
Pot odds compare the size of the pot to the amount you must call, telling you the 'price' you are getting on a call. If the pot is 100 and you must call 25, you are getting 4-to-1 odds, meaning you must win more than 1 time in 5 (about 20% of the time) for the call to break even. You compare this required break-even percentage against your equity (your chance of winning the hand). If your equity exceeds the pot-odds threshold, calling is profitable in the long run; if not, folding is better, all else equal. Pot odds are the foundational math of correct calling and are usually combined with implied odds when future betting is likely.
Worked example
Facing a 50 bet into a 150 pot, you are getting 200-to-50, or 4-to-1; you need about 20% equity to call, and with a flush draw worth roughly 35% equity, calling is clearly profitable.
Why it matters
For learners, pot odds turn vague 'should I call?' instincts into a checkable calculation and prevent chasing draws too expensively. For professionals, instant pot-odds math underlies every calling and bluff-catching decision and is the baseline that more advanced concepts refine.
