Poker Pot Odds Calculator
Calculate pot odds, required equity, and expected value to make mathematically sound poker decisions. An educational tool for understanding poker mathematics.
Understanding Pot Odds
Pot odds represent the ratio between the current pot size and the cost of a call. By comparing pot odds to your hand equity (probability of winning), you can determine whether a call is mathematically profitable in the long run. This fundamental poker concept is essential for making consistent, profitable decisions.
Calculate Your Pot Odds
Enter the pot size and the bet you're facing to calculate your pot odds and required equity to call.
Calculate Equity from Outs
Enter your number of outs to estimate your equity. Use the quick reference below for common draws.

Pot Odds Quick Reference
Common bet sizes and their corresponding pot odds and required equity.
| Bet Size (% of Pot) | Pot Odds Ratio | Required Equity | Common Use |
|---|---|---|---|
| 25% (1/4 pot) | 5:1 | 16.7% | Small blocking bet |
| 33% (1/3 pot) | 4:1 | 20.0% | Value bet / probe |
| 50% (1/2 pot) | 3:1 | 25.0% | Standard continuation bet |
| 66% (2/3 pot) | 2.5:1 | 28.6% | Value/protection bet |
| 75% (3/4 pot) | 2.33:1 | 30.0% | Large value bet |
| 100% (pot-sized) | 2:1 | 33.3% | Polarized / strong hand |
| 150% (1.5x pot) | 1.67:1 | 37.5% | Overbet |
| 200% (2x pot) | 1.5:1 | 40.0% | Large overbet |
Outs to Equity Conversion
Approximate equity based on number of outs.
| Outs | Flop to River (~) | Turn to River (~) | Example Draw |
|---|---|---|---|
| 2 | 8% | 4% | Set on board |
| 4 | 16% | 9% | Gutshot straight |
| 6 | 24% | 13% | Two overcards |
| 8 | 31% | 17% | Open-ended straight |
| 9 | 35% | 19% | Flush draw |
| 12 | 45% | 26% | Flush + gutshot |
| 15 | 54% | 33% | Flush + open-ended |
Important Considerations
- Discounting Outs: Not all outs are clean. If a flush card also gives your opponent a full house, discount that out.
- Reverse Implied Odds: Sometimes hitting your draw can still lose to a better hand, costing you more chips.
- Position: Being in position gives you more control and better implied odds.
- Opponent Tendencies: Will your opponent pay you off when you hit? Adjust implied odds accordingly.
Understanding Pot Odds in Poker
Pot odds are a fundamental concept in poker that every player should understand. They represent the mathematical relationship between the size of the pot and the bet you need to call. By comparing pot odds to your probability of winning (equity), you can make decisions that are profitable in the long run, regardless of individual hand outcomes.
According to research published in the Journal of Gambling Studies, understanding mathematical concepts like pot odds is associated with better decision-making in poker and can help players distinguish skill-based decisions from luck-driven outcomes.
How to Calculate Pot Odds
The pot odds calculation is straightforward:
- Add the current pot and the bet you're facing - This gives you the total pot after your call.
- Divide the total pot by the bet size - This gives you your pot odds ratio.
- Convert to a percentage - Divide the bet by the total pot to get the required equity.
For example, if the pot is €100 and your opponent bets €50:
- Total pot after call = €100 + €50 + €50 (your call) = €200
- Pot odds ratio = €200 : €50 = 4:1
- Required equity = €50 / €200 = 25%
This means you need at least 25% equity to make a profitable call in the long run.
Pot Odds vs. Equity
Once you know your pot odds, you compare them to your estimated equity:
- Equity > Required Equity: Calling is mathematically profitable (+EV)
- Equity < Required Equity: Calling loses money in the long run (-EV)
- Equity = Required Equity: Break-even; consider other factors

Implied Odds Explained
Implied odds extend the pot odds concept by considering money you might win on future streets. This is particularly relevant when:
- Your pot odds are insufficient for a direct call
- You have a drawing hand that could become very strong
- Your opponent has a deep stack behind
- Your draw is well-hidden (they won't see it coming)
The European Gaming and Betting Association (EGBA) emphasizes that poker, unlike purely chance-based casino games, involves significant skill elements. Understanding concepts like implied odds is part of the skill set that distinguishes poker from games of pure chance in many regulatory frameworks.
Common Mistakes to Avoid
When using pot odds, be aware of these common errors:
- Forgetting to include your call in the pot: Always add your call to calculate the total pot you're competing for.
- Overestimating implied odds: Not every opponent will pay you off when you hit.
- Not discounting outs: Some outs may give your opponent an even better hand.
- Ignoring position: Position significantly affects your ability to realize implied odds.
- Multi-way pot miscalculations: With multiple players, odds and equity calculations become more complex.
