Preflop Equity Calculator

Formula

The formula to calculate the Preflop Equity (PE) is:

\[ PE = \left( \frac{W + \left(\frac{T}{2}\right)}{H} \right) \times 100 \]

Where:

\(PE\) is the preflop equity (%)
\(W\) is the number of ways to win the hand
\(T\) is the number of ties
\(H\) is the total number of possible outcomes

Preflop Equity Definition

Preflop equity in poker refers to the statistical likelihood of a particular hand winning before the flop (the first three community cards) is dealt. It is calculated by comparing the strength of a player’s hand to all possible hands that their opponents could hold. This concept is crucial in making informed decisions about whether to fold, call, or raise before the flop. The higher the preflop equity, the higher the chances of winning the hand.

Example Calculation

Let's assume the following values:

Number of Ways to Win (W) = 30
Number of Ties (T) = 10
Total Number of Possible Outcomes (H) = 100

Using the formula to calculate the Preflop Equity (PE):

\[ PE = \left( \frac{30 + \left(\frac{10}{2}\right)}{100} \right) \times 100 = 35 \]

The Preflop Equity (PE) is 35 %.
