Poker Pot Odds Calculator: Master the Math

Pot odds are fundamental to winning poker—they tell you when calling is mathematically profitable. Our free calculator computes pot odds instantly, compares them to your equity, and helps you make correct decisions.

What Are Pot Odds?

Pot odds express the ratio between the current pot and the cost to call. They help you determine if a call is profitable based on your chance of winning.

Quick Answer: Pot odds = Pot Size : Call Amount. If the pot is $100 and you need to call $20, your pot odds are 5:1 (or 16.7%). If your equity exceeds 16.7%, calling is profitable. Always compare pot odds to your equity—call when equity is higher.

Input Fields Explained

Field	Description	Example
Pot Size	Current pot total	$150
Call Amount	Bet you're facing	$50
Pot Odds Ratio	Pot : Call	3:1
Pot Odds %	Break-even equity	25%
Your Equity	Winning probability	32%
Decision	Based on comparison	Call (+EV)

Pot Odds Calculation

Basic Formula

Pot Odds Ratio = Pot Size : Call Amount
Pot Odds % = Call / (Pot + Call) × 100

Example Calculation

Situation:

• Pot: $80
• Bet to call: $20

Ratio:

Pot Odds = $80 : $20 = 4:1

Percentage:

Pot Odds % = $20 / ($80 + $20) = $20 / $100 = 20%

You need 20% equity to break even on a call.

Comparing Pot Odds to Equity

The Golden Rule

Comparison	Decision
Equity > Pot Odds %	Call (profitable)
Equity < Pot Odds %	Fold (unprofitable)
Equity = Pot Odds %	Break-even (marginal)

Equity Reference Chart

Hand/Draw	Equity vs. Random
Flush draw (9 outs)	35% (turn + river)
Open-ended straight	31% (turn + river)
Gutshot straight	17% (turn + river)
Overcards (6 outs)	24% (turn + river)
Set vs. flush draw	~66%
Overpair vs. underpair	~82%

Real-World Pot Odds Examples

Example 1: Flush Draw on Flop

Situation:

• You hold: A♥ K♥
• Board: 9♥ 5♥ 2♣
• Pot: $60
• Opponent bets: $30

Calculation:

• Pot odds: $60 : $30 = 2:1
• Pot odds %: $30 / $90 = 33.3%
• Flush draw equity: ~35% (two cards to come)

Decision: Call. Your 35% equity exceeds the 33.3% required.

Example 2: Gutshot on Turn

Situation:

• You hold: J♠ 10♠
• Board: A♣ Q♦ 7♥ 3♠
• Pot: $100
• Opponent bets: $50

Calculation:

• Pot odds: $100 : $50 = 2:1
• Pot odds %: $50 / $150 = 33.3%
• Gutshot equity: ~8.5% (one card to come)

Decision: Fold. Your 8.5% equity is way below 33.3%.

Example 3: Overcards on Flop

Situation:

• You hold: A♠ K♦
• Board: 9♣ 7♦ 2♠
• Pot: $40
• Opponent bets: $10

Calculation:

• Pot odds: $40 : $10 = 4:1
• Pot odds %: $10 / $50 = 20%
• Six overcards equity: ~24%

Decision: Call. Your 24% beats the 20% requirement.

Implied Odds

What Are Implied Odds?

Implied odds account for money you'll win on future streets if you hit your draw.

Implied Odds = (Pot + Expected Future Bets) : Call

When Implied Odds Matter

Situation	Implied Odds Value
Deep stacks	High (more to win)
Disguised draws	High (opponents will pay)
Short stacks	Low (not much behind)
Obvious draws	Low (opponents fold)

Example: Implied Odds in Action

Situation:

• You hold: 5♦ 6♦
• Board: 3♦ 4♠ K♣
• Pot: $30, Call: $20
• Stacks: $200 remaining each

Direct pot odds: 1.5:1 (40%)—too expensive for a gutshot

With implied odds:

• You expect to win ~$80 more if you hit
• Effective pot: $30 + $80 = $110
• Implied odds: 5.5:1 (15%)

Decision: Call becomes profitable with implied odds.

Outs and Equity Table

Common Drawing Hands

Draw	Outs	Turn Equity	River Equity	Turn+River
Flush draw	9	19.1%	19.6%	35.0%
Open-ended straight	8	17.0%	17.4%	31.5%
Gutshot	4	8.5%	8.7%	16.5%
Two overcards	6	12.8%	13.0%	24.1%
Flush + gutshot	12	25.5%	26.1%	45.0%
Flush + OESD	15	31.9%	32.6%	54.1%
Set to full house	7	14.9%	15.2%	27.8%

Quick Mental Math: Rule of 2 and 4

• Turn only: Outs × 2 = approximate %
• Turn + River: Outs × 4 = approximate %

Example: 9 flush outs × 4 = ~36% (actual: 35%)

Common Pot Odds Mistakes

1. Ignoring Position

Mistake: Same pot odds analysis regardless of position Reality: Position affects implied odds significantly Fix: Give yourself better implied odds in position

2. Counting Phantom Outs

Mistake: Counting outs that don't win Reality: Some "outs" complete better hands for opponents Fix: Discount outs that might be tainted

3. Forgetting Reverse Implied Odds

Mistake: Ignoring times you hit but still lose Reality: Second-best hands cost money Fix: Discount implied odds for vulnerable draws

4. Using Turn + River Equity on Turn

Mistake: Using 35% for flush draw on turn Reality: On turn, you only get one card (19%) Fix: Use single-card equity unless you're all-in

5. Not Adjusting for Opponents

Mistake: Same calculations vs. all players Reality: Tight players have stronger ranges Fix: Adjust implied odds based on opponent tendencies

Frequently Asked Questions

What pot odds do I need for a flush draw?

On the flop (two cards to come): ~35% equity, so you need ~3:1 or better pot odds. On the turn (one card): ~20% equity, so you need ~4:1.

How do I calculate pot odds quickly in-game?

Use ratios: If the pot is $100 and you call $25, that's 4:1, or 20%. With practice, common situations become automatic.

When should I raise instead of call with a draw?

When fold equity + draw equity combined exceeds your investment. Semi-bluff raises can be more profitable than calls.

Do pot odds apply to tournaments differently?

ICM considerations can make some +EV calls incorrect in tournaments. Pot odds math is the same, but total chip value changes.

What if I'm getting exactly the right odds?

Break-even calls are still correct—you're not losing money. But if there's rake or you're unsure of your equity, folding might be better.

How do implied odds change with stack depth?

Deeper stacks = higher implied odds (more to win). Short stacks have almost no implied odds.
