A pot odds calculator will help you to figure out how much equity you need to have with your hand in order for calling the current bet to be mathematically profitable for you.
Pot odds represent the ratio between the bet a player needs to call and a current pot size.
Pot odds are the basic math behind deciding whether to call or not in poker. They help you figure out if it is mathematically profitable to call a bet or raise with your hand or not.
The most convenient form of pot odds is as a percentage. That way you can directly compare pot odds value to your hand’s equity, which is also displayed as a percentage.
The formula ot pot odds are:
Pot Odds = (Bet size) / (Pot size + 2 * Bet size)
Basically, we divide the bet size by the pot size after you call.
For example, if pot size = 50 and bet size = 30, the pot odds = 30 / (50 + 30 + 30) = 27%.
In the table below you can see pre-calculated pot odds for typical bet sizings you often face in game. You can memorize these values to be more confident and spend less time on calculations while playing.
Bet size (% of the pot)
10% 25% 33% 50% 67% 75% 100% 150%
Pot Odds (equity to call)
8% 17% 20% 25% 29% 30% 33% 38%
Let's suppose you have Tc9c on the 7h8sAd board. The current pot is $40. Your opponent bets $25. Your pot odds in this spot are 25 / (40+25+25) = 28%. Do you have at least 28% equity against the opponent's range with your hand? Most likely yes, because even against a very strong range of top pair top kicker and higher you’ll have at least 32% equity.

So in this hand, according to poker math, you can profitably call and see the Turn. But also don’t forget that poker is not only about pure math. Sometimes you can call even if you don’t have the right odds. You can make a "bad" call if you’re sure that you will win a big pot if you make your hand. It’s called "Implied odds".
