How It Works

Formula

eFG% = (FGM + 0.5 × 3PM) / FGA. Each 3PM adds 0.5 to the numerator.

3pt Weight

3 points ÷ 2 points = 1.5. So one 3PM = 1.5 "effective" 2-point makes.

Expert Tips

Volume + Efficiency

More 3s at 40% = 60% eFG on those attempts. Balance volume and accuracy.

vs TS%

eFG% for shot selection; TS% for overall scoring including FTs.

Role Context

Big men dunk more → higher eFG. Guards who shoot 3s need volume to match.
