About the eFG% Calculator

The effective field goal percentage calculator adjusts shooting percentage for the extra point a three-pointer is worth: eFG% = (FG + 0.5 × 3P) ÷ FGA. A player who makes 4 of 10 threes has the same eFG% (60%) as one who makes 6 of 10 twos, because both score 12 points.

How to use it
