How to Use the Pot Odds Calculator
1. Enter the pot size — Type the total amount currently in the pot, including your opponent's bet. This is everything you can see in the middle — blinds, antes, previous bets, and the bet you're facing.
2. Enter the bet to call — Type the amount your opponent has bet (or raised) that you need to call. Alternatively, use the quick preset buttons to auto-fill common bet sizes relative to the pot: half pot, two-thirds pot, full pot, or double pot.
3. Read the results — The calculator instantly displays three key numbers: your pot odds ratio (e.g., 3 : 1), the required equity to break even on the call (e.g., 25%), and the total pot size after your call. The equity bar provides a visual representation, colored green (favorable), yellow (marginal), or red (unfavorable).
4. Make your decision — Compare the required equity to your estimated hand equity. If your hand equity exceeds the required equity, calling is mathematically profitable. If it falls short, folding is the correct play unless implied odds justify continuing.
Common Bet Sizes and Required Equity
Understanding the equity required against common bet sizes is essential for making quick, accurate decisions at the table. Here are the most common scenarios:
| Bet Size | Pot Odds | Required Equity |
|---|---|---|
| 1/4 Pot (25%) | 5 : 1 | 16.7% |
| 1/3 Pot (33%) | 4 : 1 | 20.0% |
| 1/2 Pot (50%) | 3 : 1 | 25.0% |
| 2/3 Pot (67%) | 2.5 : 1 | 28.6% |
| 3/4 Pot (75%) | 2.3 : 1 | 30.0% |
| Full Pot (100%) | 2 : 1 | 33.3% |
| 1.5x Pot (150%) | 1.7 : 1 | 37.5% |
| 2x Pot (200%) | 1.5 : 1 | 40.0% |
Memorizing these numbers lets you make snap decisions in real time. When facing a half-pot bet, you need 25% equity. Against a full-pot bet, you need 33%. These are the two most important benchmarks in no-limit poker.
Pot Odds vs. Implied Odds
Pot odds consider only the money currently in the pot, making them a pure mathematical calculation. Implied odds go a step further by estimating how much additional money you can win on future streets if you complete your draw.
For example, suppose you're on the flop with a flush draw (roughly 35% equity to complete by the river) and your opponent bets full pot. Pot odds require 33% equity, so calling is barely profitable on pure pot odds alone. But if your opponent has a strong hand they're unlikely to fold, and there's significant money behind, implied odds make this call even more attractive — you stand to win much more than what's currently in the pot.
The flip side is reverse implied odds — situations where completing your draw could cost you money. If you make the third-best flush or a non-nut straight on a coordinated board, your opponent might hold a better hand and extract additional bets from you. Always consider the strength of the hand you're drawing to, not just the probability of completing it.
Using Pot Odds in Practice
The most common practical application of pot odds is with drawing hands. On the flop, a flush draw has roughly 35% equity (9 outs x ~4 = 36%) and an open-ended straight draw has about 32% equity (8 outs x 4 = 32%). On the turn, those numbers drop to about 20% and 17% respectively (outs x ~2).
When facing a bet, quickly calculate the required equity using this formula: Bet / (Pot + Bet). Then compare it to your estimated hand equity. If your equity exceeds the requirement, call. If not, fold — unless implied odds close the gap.
Pot odds also apply to bluff-catching. If your opponent bets half pot on the river, you need 25% equity. This means you need to be right only 1 in 4 times to break even on a call. If you believe your opponent is bluffing more than 25% of the time in this spot, calling with a marginal hand becomes profitable.
Frequently Asked Questions
›What are pot odds?
Pot odds are the ratio between the current size of the pot and the cost of a call. For example, if there's $100 in the pot and you need to call $50, your pot odds are 2 : 1 (or 100 / 50). Pot odds tell you what percentage of the time you need to win the hand to break even on a call. In this example, you'd need to win at least 33% of the time — $50 / ($100 + $50) = 33.3%. If your hand wins more often than that, calling is profitable in the long run.
›How do I calculate pot odds?
There are two ways to express pot odds. As a ratio: divide the pot size by the bet you need to call. A $150 pot with a $50 bet gives you 3 : 1 pot odds. As a percentage (required equity): divide the call amount by the total pot after your call — $50 / ($150 + $50) = 25%. This percentage is your break-even point. If your hand equity exceeds 25%, calling is mathematically correct. This calculator handles both conversions for you instantly.
›What is the relationship between pot odds and equity?
Pot odds and equity work together to determine whether a call is profitable. Pot odds tell you the minimum equity (win percentage) you need to justify a call. If the pot is $200 and you face a $100 bet, you need 100 / (200 + 100) = 33.3% equity. If your hand has 40% equity against your opponent's range, calling is profitable because 40% > 33.3%. The bigger the gap between your actual equity and the required equity, the more profitable the call. When your equity falls short of the required equity, folding is the correct play.
›Should I always call if my equity exceeds pot odds?
In a vacuum, yes — if your equity is higher than the required equity from pot odds, a call is mathematically profitable. However, poker decisions involve more factors. Consider position (will you be out of position on future streets?), remaining stack sizes (are you pot-committed?), and whether your opponent might bet again on later streets, forcing you to invest more. Also consider reverse implied odds — even if you have the equity to call now, completing your draw to a non-nut hand could cost you more if your opponent holds a stronger made hand. Pot odds are the starting point, not the entire decision.
›How do implied odds affect my decision?
Implied odds account for the additional money you expect to win on future streets if you complete your draw. Standard pot odds only consider the current pot, but implied odds factor in future bets your opponent is likely to pay off. For example, if pot odds require 25% equity but you only have 20%, the call might still be correct if you expect to win a large bet when you hit. Implied odds are strongest when you have a hidden draw (like a set or a well-disguised straight), your opponent has a strong but second-best hand they won't fold, and there's significant money left behind in the stacks. Conversely, implied odds are weak when your draw is obvious (like a four-flush board) or stacks are shallow.
