What Are Pot Odds in Poker?
Pot odds refer to the ratio between the current size of the pot and the cost of a contemplated call. In simpler terms, they help you figure out whether it’s mathematically correct to call a bet based on your chances of completing your drawing hand or winning the pot.
For example, if the pot contains $100 and your opponent bets $50, you would need to call $50 to potentially win $150. Your pot odds are 3-to-1, which means you need at least a 25% chance of winning to make a profitable call. If your odds of hitting your hand are better than 25%, calling is statistically the correct decision.
Pot odds in poker are fundamental to strategic decision-making, especially when playing drawing hands like flushes or open-ended straight draws. They help prevent costly mistakes and turn borderline calls into smart long-term plays.
How to Calculate Pot Odds Step-by-Step
Learning how to calculate pot odds is essential for any poker player who wants to make smart, profitable decisions. The basic idea is to compare the size of the pot to the amount you need to call and then convert that ratio into a percentage. This percentage tells you how often you need to win the hand to break even.
Here’s a simple 3-step process to calculate pot odds during a hand:
- Step 1: Add up the total pot size, including your opponent’s current bet.
- Step 2: Determine how much you need to call to stay in the hand.
- Step 3: Divide the amount you need to call by the total pot (pot + call). Then multiply by 100 to get a percentage.
For example, if the pot is $100 and your opponent bets $50, the total pot becomes $150. You need to call $50. So the pot odds calculation would be:
Pot Odds = $50 / ($150) = 0.333 or 33.3%
This means you need at least a 33.3% chance of winning the hand for your call to be break-even or profitable. If your actual chance of winning (based on outs) is higher, you should call.
Pot Odds Formula

To calculate your pot odds as a percentage, you can use this simple formula:
Pot Odds % = (Call Amount / (Pot Size + Call Amount)) × 100
This pot odds formula tells you the minimum equity (chance of winning) you need to make a profitable call. If your estimated chance of winning the hand is higher than the pot odds percentage, the call is correct.
Let’s say the pot is $80, and your opponent bets $20. You need to call $20 to win a total of $100.
Pot Odds = 20 / (80 + 20) = 0.20 → 20%
You need at least a 20% chance of winning the hand for this call to be mathematically justified. If your odds of completing your draw are better, this is a good call in the long run.
Real-World Example: Should You Call or Fold?
Calculating Pot Odds in Poker: Step-by-Step Example
Let’s walk through a full example of calculating pot odds in poker so you can see how this works in a real hand.

You’re on the turn with a flush draw, holding . The board is . There’s $120 in the pot and your opponent bets $60. You need to call $60 to see the river.
Step 1: Total pot after the bet = $120 + $60 = $180
Step 2: Use the pot odds formula:
Pot Odds = 60 / (180) = 0.333 → 33.3%
Step 3: Count your outs. You have 9 outs to complete your flush. With one card to come, that’s about a 19.6% chance of hitting.
Since your actual chance (19.6%) is lower than the pot odds (33.3%), this call is not profitable in the long run — unless you expect to win more money on the river (implied odds).
This example shows why understanding pot odds in poker is so important: it prevents you from calling bets that seem tempting but are mathematically incorrect.

Making Better Decisions with Math
Knowing how to calculate pot odds is just the beginning — the real value comes from applying them consistently and correctly in real hands. Here are several strategic tips to help you use pot odds like a pro:
- Compare pot odds to hand odds: Use your outs to estimate the chance of completing your hand, and compare that to your pot odds percentage.
- Avoid overvaluing weak draws: Just because you have a draw doesn’t mean it’s worth calling — only do so when the math checks out.
- Combine with implied odds: Sometimes your current pot odds don’t justify a call, but potential future winnings (implied odds) might make it profitable.
- Make your opponents fold: If you’re betting, use your knowledge of pot odds to size your bets and reduce your opponent’s profitable calling range.
Understanding pot odds in poker helps you avoid emotional decisions and base your actions on pure math. Whether calling or bluffing, this concept sharpens your edge and improves your long-term win rate.

FAQs About Pot Odds
Pot odds represent the ratio between the size of the pot and the cost of a call. They help players decide whether calling a bet is mathematically profitable based on their chance of winning the hand.
Divide the amount you need to call by the total pot (including your call), then multiply by 100 to get a percentage. This tells you the minimum equity you need to make a profitable call.
Pot Odds % = (Call Amount / (Pot Size + Call Amount)) × 100
There’s no single “good” number — it depends on your drawing odds. For example, if you have a flush draw with one card to come (about 19.6% chance), you should only call if pot odds are 19.6% or better.
Pot odds are based on the current pot, while implied odds factor in money you expect to win on future streets if you hit your hand.
