Fold Equity Calculator

Show Your Love:

The Fold Equity Calculator is a poker strategy tool that helps players estimate the expected value (EV) of a bet or raise when considering the chance that their opponent might fold. In competitive poker—especially no-limit Texas Hold’em—making profitable plays hinges not only on your hand strength but also on your opponent’s potential reaction. Fold equity refers to the value gained when your opponent folds, allowing you to win the pot without a showdown.

This calculator belongs to the Poker Strategy & Decision Tools category. It enables players to combine fold probability with expected post-call outcomes to evaluate the overall profitability of aggressive moves like bluffs or semi-bluffs.

Formula of Fold Equity Calculator

Fold Equity

Where:

Fold % = Probability the opponent folds to your bet (as a decimal or percentage)

Current Pot = Total pot before your action

Call % = 1 − Fold %

Post-Call EV = Expected value if the opponent calls (can be negative if you’re behind)

Key Insight:
Fold equity adds positive value even when you're behind in hand equity, as long as the opponent folds often enough to offset losses when called.

Table: Quick Reference – Fold Equity Scenarios

Fold %Current PotPost-Call EVExpected Value (EV)
60%$100-$50(0.6 × $100) + (0.4 × -$50) = $60 - $20 = $40
40%$150$20(0.4 × $150) + (0.6 × $20) = $60 + $12 = $72
70%$80-$70(0.7 × $80) + (0.3 × -$70) = $56 - $21 = $35

This table helps players quickly evaluate if a bluff or semi-bluff is profitable based on various fold probabilities and pot sizes.

Example of Fold Equity Calculator

Let’s say the pot is $120, and you're considering a bluff. You estimate:

Fold % = 65%

Post-Call EV = -$40 (because you likely lose if called)

Now calculate EV:

EV = (0.65 × 120) + (0.35 × -40)

EV = 78 - 14 = $64

Result: The move has a positive expected value of $64, making the bluff a good play in the long run.
