Pot odds
Pot odds are the price you are offered on a call: what you have to put in compared with what the pot would be worth to you, converted into the share of the time you need to win for the call to break even.
The sum is the same every time. Divide your call by the pot after your call is in. A bet of 50 into a pot of 100 asks you to call 50 into a pot that becomes 200, so you need to win 25% of the time.
That 25% is the whole answer to whether the price is fair. If your hand wins more often than that, calling makes money over time; if it wins less often, it loses money over time, whatever happens in this particular hand.
an example
your cards
board
The pot is 100 and your opponent bets 50. You need 25% to break even. Nine hearts give you 35.0% by the river, so the price is better than the hand needs, and calling is profitable even though you are behind right now.
This example is made up. The real one is in your own hand history: find pot odds in your own hands and see how often it came up and what it cost you.
