Fold Equity

What Is Fold Equity?

Fold equity is the value you gain when an opponent folds to your bet or raise. Every time you put chips in the pot aggressively, there is some probability your opponent surrenders the pot without a showdown. That probability, multiplied by the current pot size, represents your fold equity — the immediate profit from winning uncontested.

The Fold Equity Formula

Fold Equity = Probability of Opponent Folding x Current Pot Size

For a complete picture of any aggressive action, combine fold equity with your hand equity when called:

Total EV = Fold Equity + (1 - Fold Probability) x (Your Equity When Called x Final Pot - Your Bet)

This combined calculation explains why Semi-Bluff plays are so powerful. Even with a drawing hand, the combination of fold equity and hand equity frequently produces a +EV result.

Practical Example: Tournament All-In

You are on the bubble of a tournament with 12 big blinds. You shove all-in from the cutoff with A♠5♥. The pot contains 2.5 big blinds in antes and blinds. You estimate the remaining players fold approximately 70% of the time due to ICM pressure. Fold equity = 0.70 x 2.5BB = 1.75BB. When called (30% of the time), your A5o has roughly 38% equity. Total EV = 1.75 + 0.30 x (0.38 x 27 - 12) = 1.75 + 0.30 x (10.26 - 12) = 1.75 - 0.52 = +1.23BB. The shove is profitable primarily because of fold equity.

When Fold Equity Is Highest

• Opponent's range is weak or capped: Players who checked or called passively have few strong hands
• Board texture favors your range: Scare cards (aces, completing draws) increase fold frequency
• ICM pressure exists: Tournament players near the bubble or pay jumps fold more to avoid elimination
• Your Bluff tells a credible story: Your betting line logically represents strong hands

Fold Equity in Tournament Play

Fold equity becomes especially critical in tournament endgame situations where ICM magnifies the cost of elimination. Preflop+ ICM mode calculates optimal push/fold ranges that account for fold equity against each stack size at the table.
