The pot odds are the ratio between the pot size and the odds you have to call. Remember that the pot includes all bets made in the current round. One of the most important things to consider when deciding whether to call or fold in poker is your pot odds. Without this simple calculation, you simply can’t determine if a certain call is profitable or not. Now lets learn how to calculate pot odds in poker using basic examples. 

For example, if the pot is $100 and your opponent bets $50, the total pot will be $150. You are getting 3:1 on a call that you make. Once you have your pot odds, you’ll want to convert them into a percentage so that you know how much equity your hand has to profitably call the bet.

The first step is to figure out the pot size if you called the bet, which in this case would be $200 ($150 total pot + your $50 call) This is how much money we’re talking about overall being your final pot. 
Your second step would be dividing the size of the call you made by the size of the final pot you got. In our case, we will get a 0.25 result, dividing $50 by $200 of the final pot.

Finally, all you have to do is to multiply the result you got by 100. In our example, we are getting 25%. It means that you need to win more than 25% if you want to get some profit with your calls.
