eFG% = (FGM + 0,5×3PM) / FGA × 100
About this calculator
The Basketball Shot Calculator (eFG%) computes the Effective Field Goal Percentage, an advanced metric that adjusts shooting efficiency by valuing three-point baskets. Unlike standard field goal percentage (FG%), eFG% accounts for the fact that a three-pointer is worth more than a two-pointer, providing a more accurate view of a player's or team's offensive efficiency.
The formula is: eFG% = (FGM + 0.5 × 3PM) / FGA × 100, where FGM is field goals made, 3PM is three-pointers made, and FGA is field goals attempted. The number of three-pointers is multiplied by 0.5 to adjust for their extra value. The result is a percentage showing how many effective points are generated per shot attempt.
Use this calculator to analyze player or team performance, compare efficiency across different playing styles, or evaluate the impact of long-range shooters. It is useful for coaches, sports analysts, and fans seeking a fairer metric than traditional FG%, especially in leagues where three-point shots are common, such as the NBA.
Caution: eFG% does not include free throws, so it does not reflect overall scoring efficiency. Also, it does not account for shot volume; a player with a high percentage but few attempts may have limited impact. Use alongside other metrics like TS% (True Shooting Percentage) for a comprehensive analysis.
Frequently asked questions
What does eFG% mean?
eFG% stands for Effective Field Goal Percentage. It is a metric that adjusts shooting efficiency by giving extra weight to three-point baskets.
What is the difference between FG% and eFG%?
FG% is the percentage of field goals made without distinguishing between two and three points. eFG% gives extra weight to three-pointers, better reflecting the true value of each shot.
How do I interpret the eFG% result?
For example, an eFG% of 55% means that for each shot attempted, the player effectively generates 1.1 points (55% x 2). Higher is better.
Does eFG% include free throws?
No. eFG% only considers field goals (two and three pointers). To include free throws, use the TS% (True Shooting Percentage) metric.
Can I use eFG% to compare players from different positions?
Yes, but with caution. Perimeter players tend to attempt more three-pointers, which can inflate eFG%. Compare within similar contexts.
