Poker EV Calculator
Enter your equity (win probability), the pot you stand to win, and the amount you need to call or bet. The calculator shows your expected value in dollars or big blinds, the break-even equity needed to profit, and a scenario comparison so you can see at a glance whether the play is +EV or -EV. Switch to Semi-Bluff mode to factor in fold equity on top of your showdown equity.
What is Expected Value (EV) in poker?
Expected value is the average result of a decision when repeated many times. In poker, every action you take (call, fold, bet, raise) has an EV: the weighted average of all possible outcomes, each multiplied by its probability. A +EV play earns chips on average; a -EV play loses them. Poker profitability comes from consistently making +EV decisions over thousands of hands, not from winning any single pot.
The poker EV formula
The core formula is: EV = (Probability of winning x Amount won) - (Probability of losing x Amount lost). For a call situation this simplifies to: EV = (Equity x Total pot) - ((1 - Equity) x Call amount). The break-even equity, also called the pot odds equity, is: Call / (Pot + 2 x Call). If your actual equity exceeds this threshold, calling has positive EV.
How to use the semi-bluff mode
A semi-bluff is a bet or raise with a hand that is not yet the best hand but has outs to improve. Its EV comes from two sources: fold equity (the times your opponent folds immediately, winning you the pot) and showdown equity (the times you are called and still win at showdown). The formula is: EV = (Fold equity x Pot) + (Call probability x (Showdown equity x Total pot - (1 - Showdown equity) x Bet)). Even a hand with modest showdown equity can be a profitable semi-bluff if fold equity is high enough.
Pot odds and break-even equity
Pot odds tell you the minimum equity needed to make a call break-even. If the pot is $100 and the bet is $50, you are getting 100:50 pot odds, which means you need at least 50 / (100 + 2 x 50) = 25% equity to call. Any equity above 25% makes the call +EV. Pot odds work best on the river where you know your exact equity; on earlier streets you also need to consider implied odds and the risk of being outdrawn.
Poker EV decision guide
| EV range | Decision label | Interpretation |
|---|---|---|
| Above 0 | +EV | Profitable long-term - make this play consistently |
| Exactly 0 | Break-even | Neutral - other factors (variance, ICM) decide |
| Below 0 | -EV | Losing play long-term - fold or find a better line |
| Large positive | Strongly +EV | High-confidence play - prioritize over marginal spots |
| Large negative | Strongly -EV | Clear mistake - avoid regardless of gut feel |

Frequently asked questions
What does +EV and -EV mean in poker?
+EV means the play has positive expected value: on average you profit from making it. -EV means the play loses money on average. In the short run variance means you can lose a +EV hand or win a -EV one, but over thousands of repetitions the long-run average converges to the EV figure.
How do I find my equity in a hand?
Equity is your share of the pot based on the probability each hand wins at showdown. Use an equity calculator (such as Equilab, Flopzilla, or a built-in solver) to input your hand and your estimate of the opponent range, then run it against the board. The resulting percentage is your equity to enter here.
Can I use big blinds instead of dollars?
Yes. Switch the unit selector to "Big blinds (BB)" and enter all amounts in big blind units. EV in big blinds is useful for comparing spots across stakes, because a play worth 5 BB is equally profitable at any buy-in level.
What is fold equity and why does it matter?
Fold equity is the probability your opponent folds to your bet or raise. When you have fold equity, you can profit even with a weak hand because you sometimes win the pot without showdown. Semi-bluffs combine fold equity with draw equity to create plays that are +EV even when neither component alone would be enough.
How is EV different from pot odds?
Pot odds tell you the break-even equity needed to call - a single threshold. EV tells you the actual dollar or BB value of the decision, which requires both pot odds and your exact equity. A call with 40% equity into a pot that requires 25% equity is +EV; pot odds confirm it is profitable but EV tells you by how much.
Does EV account for tournament ICM pressure?
No. This calculator computes chip EV, which treats all chips as equal. In tournaments, the Independent Chip Model (ICM) assigns a different dollar value to each chip depending on stack sizes and payout structure. A call that is chip-EV positive can be ICM-negative near a pay jump or final table bubble.
