Fold Equity Calculator
Fold equity is a critical concept in poker strategy, especially when playing more aggressive styles like bluffing. It refers to the extra value a player gains from making an opponent fold their hand. Knowing how to calculate fold equity can help players decide whether making a bet or a raise is worthwhile. This calculator simplifies the process by giving an accurate calculation based on the current odds factor and the opponent’s equity.
Formula
The fold equity formula is as follows:
Fold Equity (FE) = (COF / 100) × OE
Where:
- COF = Current odds factor (percentage of chances that the opponent folds)
- OE = Opponent’s equity (likelihood that the opponent holds a better hand)
How to Use
- Enter the current odds factor (COF), which represents the likelihood that your opponent will fold. This is expressed as a percentage.
- Enter your opponent’s equity (OE), which reflects the likelihood that the opponent has a stronger hand.
- Click the “Calculate” button to get the fold equity (FE).
- The result will display the fold equity, showing whether a bluff or aggressive play is worth attempting.
Example
Let’s say you are in a situation where your opponent is likely to fold 40% of the time (COF = 40), and their equity in the hand is 30% (OE = 30). The fold equity calculation would be:
FE = (40 / 100) × 30 = 12
This means that the fold equity is 12%, meaning that you have a 12% chance of winning the pot purely by making the opponent fold.
