What Are Pot Odds?
Pot odds express the relationship between the size of the pot and the size of the bet you’re facing. They answer: “What percentage of the pot am I investing?”
The Basic Calculation
Pot Odds = Call Amount ÷ (Pot + Call Amount)
Example 1
- Pot: $100
- Opponent bets: $50
- You need to call: $50
- Pot odds: 50 ÷ (100 + 50 + 50) = 50 ÷ 200 = 25%
You’re investing 25% of the final pot to win it.
Example 2
- Pot: $200
- Opponent bets: $200 (pot-sized bet)
- Pot odds: 200 ÷ (200 + 200 + 200) = 200 ÷ 600 = 33%
Pot-sized bets always offer 33% pot odds.
Comparing to Your Equity
Once you know your pot odds, compare them to your equity (chance of winning):
| If Your Equity Is… | And Pot Odds Are… | Then… |
|---|---|---|
| Higher than pot odds | 25% | +EV Call (profitable) |
| Lower than pot odds | 25% | -EV Call (unprofitable) |
| Equal to pot odds | 25% | Break-even |
Quick Reference: Common Bet Sizes
| Bet Size | Pot Odds You’re Getting |
|---|---|
| 1/4 pot | 16.7% |
| 1/3 pot | 20% |
| 1/2 pot | 25% |
| 2/3 pot | 28.6% |
| 3/4 pot | 30% |
| Pot | 33% |
| 2x pot | 40% |
Practical Example
You have A♥K♥ on a board of Q♥7♥3♦2♣. You missed your flush draw, but have 9 outs (remaining hearts) to make your flush.
- Your equity: ~20% (9 outs × 2.2)
- Opponent bets half pot
- Your pot odds: 25%
Since 20% < 25%, this is a losing call. You need better than 25% equity to call profitably.
Implied Odds
Pot odds only consider the current pot. Implied odds factor in future bets you might win:
When to consider implied odds:
- You’re drawing to a disguised hand (like a flush)
- Your opponent will likely pay off if you hit
- Stacks are deep
When implied odds are weak:
- Opponent is short-stacked
- Obvious draw on the board
- Opponent can fold to aggression
The Quick Math Shortcut
For draws, multiply your outs by:
- 2 for one card to come
- 4 for two cards to come (flop to river)
This gives you approximate equity.
| Outs | 1 Card | 2 Cards |
|---|---|---|
| 4 (gutshot) | 8% | 16% |
| 8 (OESD) | 16% | 32% |
| 9 (flush draw) | 18% | 36% |
| 12 (flush + gutshot) | 24% | 48% |
| 15 (flush + OESD) | 30% | 60% |
Summary
- Calculate pot odds (call ÷ total pot)
- Estimate your equity
- Call if equity > pot odds
- Factor in implied odds when applicable
Master this, and you’ll make mathematically sound decisions at the table.
