1. What is Effective Field Goal Percentage?

Effective Field Goal Percentage (eFG%) is a basketball statistic that adjusts field goal percentage to account for the fact that three-point field goals count for three points while field goals only count for two points.

2. How Does the Calculator Work?

The calculator uses the eFG% formula:

Where:

• \( FG \) — Field goals made (count)
• \( 3P \) — 3-point field goals made (count)
• \( FGA \) — Field goal attempts (count)

Explanation: The formula gives 50% more credit for made three-pointers since they're worth 50% more points than two-pointers.

3. Importance of eFG%

Details: eFG% is considered a better measure of shooting efficiency than traditional FG% because it properly values three-point shooting. It's widely used in basketball analytics to evaluate player and team performance.

4. Using the Calculator

Tips: Enter the number of field goals made, three-pointers made, and total field goal attempts. All values must be non-negative integers, and FGA must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Why use eFG% instead of regular FG%?
A: eFG% accounts for the extra value of three-point shots, giving a more accurate picture of shooting efficiency.

Q2: What is a good eFG% in basketball?
A: In the NBA, league average is typically around 50-52%. Above 55% is excellent, while below 48% is poor.

Q3: How does eFG% differ from true shooting percentage?
A: True shooting percentage also accounts for free throws, while eFG% only considers field goal attempts.

Q4: Can eFG% be higher than 100%?
A: No, the maximum possible eFG% is 150% (if a player only makes three-pointers and doesn't miss any).

Q5: Why is the multiplier 0.5 for three-pointers?
A: Because three-pointers are worth 1.5 times as much as two-pointers (3/2 = 1.5), so we add half the value.
