1. What is Poker Preflop Equity?

Definition: Equity represents your expected share of the pot based on the probability of winning the hand.

Purpose: It helps poker players make mathematically sound decisions about calling, raising, or folding before the flop.

2. How Does the Equity Calculator Work?

The calculator uses the formula:

Where:

• \( Equity \) — Expected share of pot (USD)
• \( Favorable\ Outcomes \) — Number of winning hands
• \( Total\ Outcomes \) — Total possible hands
• \( Pot\ Size \) — Total pot amount (USD)

Explanation: The ratio of winning hands to total possible hands gives your probability of winning, which is then multiplied by the pot size to determine your expected value.

3. Importance of Equity Calculation

Details: Understanding your equity helps determine whether a call is profitable in the long run and is fundamental to game theory optimal (GTO) play.

4. Using the Calculator

Tips: Enter the number of hands you can win (favorable outcomes), total possible hands, and the current pot size. All values must be ≥ 0, and total outcomes must be > 0.

Q4: How does equity change post-flop?
