Poker Expected Value (EV) Calculator
Calculate the expected value of any poker call or bet.
Enter pot size, call amount, and hand equity to see if a decision is mathematically profitable.
Expected Value (EV)
Poker Expected Value Formula
EV = (Equity × Amount Won) − ((1 − Equity) × Amount Lost)
Where:
- Equity = your probability of winning the hand (0 to 1)
- Amount Won = pot size + opponent’s call (total you win if you win)
- Amount Lost = your call amount
Example: Pot = $100, call = $25, your equity = 40%
- EV = (0.40 × $125) − (0.60 × $25) = $50 − $15 = +$35
- Positive EV → calling is profitable long-term
Break-even equity (pot odds): Equity needed = Call / (Pot + Call)
If your actual equity exceeds this threshold, the call has positive EV.
Implied odds extend this concept — if you expect to win more money on later streets when you hit, you can call with slightly worse pot odds. This calculator uses direct pot odds only.
A single hand result is random. EV only matters over many repetitions. Consistently making +EV decisions is the foundation of winning poker.
