## What are Pot Odds?

You have probably heard of pot odds but maybe you’re not sure what they are or how to calculate them? Don’t worry, everyone has been there. Basically, pot odds are the comparison of the cost of making a call compared to the size of the pot. It is usually expressed as a ratio; however, the far more valuable tool is the conversion of ratio to percentage. Most poker players find it easier to understand things as percentages than ratios.

## How to Calculate Pot Odds?

Pot Size Versus Amount to Call = Pot Odds as Ratio
\$100: \$10 or 10:1
I think it is more valuable to see this as a percentage. To convert this, we simply add the pot size and the amount to call and divide the amount to call by the pot size. Using the example above, it would be:

\$100 + \$10 = \$110
\$10 / \$110 = 9%

## What is the Point?

Understanding the maths is very important to being a long-term winner at poker. Decision making is often based on the maths aspect, is a call profitable? Are they bluffing often enough? etc. In order to use poker maths effectively, a poker player combines the context of the situation with the odds at hand. It also allows one to manipulate the pot odds and enforce errors on the part of your opponents. This is a key skill requirement for winning poker.
Let’s look at an example of how pot odds could be used for important decision making.
