Effective Field Goal Percentage

This stat measures a team's ability to shoot 2-point and 3-point shots.

A team's field goal percentage is calculated by the number of shots attempted divided by the number of shots made. This includes both 2-point and 3-point shots.

FG% = FGM/FGA * 100

For example, in the 2017 NCAA Tournament Third Round match up between South Carolina and Duke, South Carolina made 20 of its 28 shot attempts in the second half en route to scoring 65 points.

The Gamecocks' field goal percentage was 71%.

FG% = 35/49 = 0.714 * 100

Effective field goal percentage takes into account that a 3-point field goal is worth more than a 2-point field goal.

eFG% = (.5 * 3FGM + FGM) / FGA * 100

South Carolina made 4 3-point shots and attempted 5 in the second stanza. 4 of their 20 made shots were worth 3 points. And 5 of their 28 shot attempts were 3-pointers.

South Carolina's eFG% was 79% in the second half.

(eFG% = (.5 * 4 + 20) / 28 = 0.785 * 100)

Why this statistic is important

Effective field goal percentage indicates how easily a team scores most of its points. A higher percentage shows a team is efficient at shooting and likely has a chance to win many games.

A team's ability to defend or lower their opponent's eFG% is equally important. If a team can hold their opponent to a lower eFG%, the better chance it has to win.
