How to use the pot odds calculator
- Pot size: everything in the middle including your opponent's bet, before you call.
- Amount to call: what it costs you to continue.
- Outs: the cards that will most likely give you the best hand. Use the quick buttons for common draws.
- Cards to come: choose whether you are on the flop seeing one card, on the flop all-in seeing two cards, or on the turn.
What are pot odds?
Pot odds compare the cost of a call with the size of the pot you can win. As a percentage, they tell you the minimum equity you need for a call to break even:
Required equity = Call ÷ (Pot + Call)
If the pot is $100 after your opponent bets and you must call $50, you are risking $50 to win $150 in total, so you need to win at least 33.3% of the time.
Counting outs
| Draw | Outs | Flop → turn | Flop → river |
|---|---|---|---|
| Flush draw | 9 | 19.1% | 35.0% |
| Open-ended straight draw | 8 | 17.0% | 31.5% |
| Flush + open-ended straight draw | 15 | 31.9% | 54.1% |
| Gutshot straight draw | 4 | 8.5% | 16.5% |
| Two overcards | 6 | 12.8% | 24.1% |
| Set to full house or quads | 7 | 14.9% | 27.8% |
The rule of 2 and 4
A quick mental shortcut: multiply your outs by 2 for one card to come, or by 4 for two cards to come. Nine outs × 4 ≈ 36%, close to the real 35%.
Pot odds example
On the flop the pot is $100, your opponent bets $50 (pot now $150) and you have a flush draw. You must call $50 to win $200 total, so you need 25% equity. If you see only the turn, your flush draw hits 19.1% of the time — not enough on immediate odds. You would need to win about $61 more on later streets (implied odds) to make the call profitable. If your opponent is all-in and you see both cards, you have 35% and the call is clearly profitable.
Implied odds and reverse implied odds
Implied odds are the extra money you expect to win when you hit. They justify calls that look slightly too expensive. Reverse implied odds are money you lose when you hit but still have the worse hand — for example, making a small flush when your opponent holds a bigger one. Discount outs that may not be clean.

Pot odds calculator FAQ
Do I include my own call in the pot?
No. Enter the pot before your call; the calculator adds your call for you.
What's the difference between pot odds and equity?
Pot odds are the price you're being offered; equity is your chance of winning. Call when equity is higher than the required equity.
Why use one card instead of two on the flop?
Unless your opponent is all-in, you will likely face another bet on the turn, so you're only guaranteed to see one card at the current price.
