Holdem Pot Odds
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.
Pot odds is simply a ratio of the amount of money in the pot compared with how much money it takes to call. The higher the ratio, the better your pot odds are. If there are $12 in the pot and it costs $4 to call then you are getting 3:1 odds ('cost to stay in').
- Pot Odds: 25% As we have already found out we have 17% chance of making the straight on the next card, which means that we should only call 17% of what is in the pot. Because we are being forced to pay 25% to play on, we should fold. We would be losing money in the long run if we called.
- Pot odds in poker simply means the “price” that it costs you to continue with your hand. For example, if you’re in a hand where the pot is $100 and your opponent bets $50, you’re getting 3 to 1 pot odds to call. The pot is $150 (the $100 that’s already there plus the $50 bet) and it costs $50 to continue. Divide the $150 by $50 to get 3.
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.

Example of using Pot Odds
The pot is $50 on the turn with just the river left to come. Player A has a flush draw holding Kc 10c:

The board reads:
Player B has Ad 8d:
Player B is considering how much to bet with their top two pair. By betting $30, the pot will be $80 and Player A will be getting $30 for a pot of $110. Using the method above, we can see this can be converted to represent 27%.
With a flush draw and one card to come we know there is approximately 18% chance of Player A making the best hand, thus, the bet enforces an error on the part of Player A as they are not getting a sufficient price to make the call.

On the other hand, if Player B bets $10, Player A will have 16.6% and a turn call becomes profitable. See how important it is to size your bets?

As we can see from the above example, pot odds can influence decision making and affect your long-term profitability. They should be used in combination with your hand reading, context and implied odds (look out for future article on implied odds). One of the great things about poker is you are in control of your decisions. By understanding odds and relative hand strength, you can learn to manipulate pot sizes (something not possible with slot odds) how you want to and enforce mistakes from opponents.
