Effective field goal percentage

In basketball, effective field goal percentage (abbreviated eFG%) is a 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. [1] Its goal is to show what field goal percentage a two point shooter would have to shoot at to match the output of a player who also shoots three pointers. [2]

It is calculated by:

where:

  • FG = field goals made
  • 3P = 3 point field goals made,
  • FGA = field goal attempts,

[3]


A rough approximation can also be had by:

where:

  • PPG = points per game
  • FT = the free throws made
  • FGA = field goal attempts

The advantage of this second formula is that it highlights the aforementioned logic behind the statistic, where it is pretended that a player only shot two point shots (hence the division of non-free-throw points by 2).


An additional formula that seems to be more in use by the statistics actually displayed on websites (but less cited by said websites) is:

where:

  • 2FG = 2 point field goals made
  • 3FG = 3 point field goals made
  • FGA = field goal attempts
