The Basketball Shooting Efficiency calculator computes the efficiency metric based on the number of 2 point and 3 point goals made and the number of attempts.
INSTRUCTIONS: Enter the following:
- (2P) Two Point Goals Made
- (2PA) Two Point Shot Attempts
- (3P) Three Point Goals Made
- (3PA) Three Point Shot Attempts
- (FF) Free Throw Goals Made
- (FFA) Free Throw Attempts
Effective Field Goal Percentage (EFG%): The calculator returns the Effective Field Goal Percentage. The calculator also returns the following:
- (TS) Total Score
- (EFG%) Effective Field Goal Percent
- (%2s) Shooting Percent of 2 Point Goals
- (%3s) Shooting Percent of 3 Point Goals
- (%FT) Shooting Percent of Free Throws
- (TSA) Total Field Shot Attempts (not including Free Throws)
- (2P) Percent of 2 Point Shots of All Attempts
- (3P) Percent of 3 Point Shot of All Attempts
The Math / Science
Effective Field Goal percentage gives you an accurate reading on who is shooting better... you or your opponent. E.F.G% gives more credit to made 3 point field goals since they yield 1.5 times the scoring of a 2 point field goal.
The formula for Effective Field Goal Percentage is:
EFG% = (2P + (1.5 * 3P) ) / AT
where:
- EFG% = Effective Field Goal Percentage
- 2P = 2 point goals made
- 3P = 3 point goals made
- AT = Total Shots attempted in the field (2PA + 3PA)
