How it works
The amount you must call is divided by the total pot after your call.
Inputs explained
| Field | What to enter |
|---|---|
| Pot size before your call (incl. bet) | A number |
| Amount to call | A number |
| Outs (cards that win) | A number |
| Cards to come | Choose one: One card (turn or river), Two cards (flop to river) |
What each result means
- Required equity = [Amount to call]÷([Pot size before your call (incl. bet)] + [Amount to call])×100
- Pot odds = [Pot size before your call (incl. bet)]÷[Amount to call]
Example values
How the main result changes when Pot size before your call changes and everything else stays at the example values above:
| Pot size before your call (incl. bet) | Required equity (%) |
|---|---|
| 75 | 40 |
| 112.5 | 30.8 |
| 150 | 25 |
| 187.5 | 21.1 |
| 225 | 18.2 |
| 300 | 14.3 |
Formula
Required equity = call ÷ (pot + call) × 100Worked example
Inputs — Pot size before your call (incl. bet): 150; Amount to call: 50; Outs (cards that win): 9; Cards to come: One card (turn or river).
Results — Required equity = 25 %; Pot odds = 3 : 1; Your approximate equity (rule of 2 and 4) = 18 %.

Multiply outs by 2 with one card to come or by 4 with two to estimate equity.
What about implied odds?
Future bets you may win can justify calls with slightly less equity.
