Basketball Shooting Efficiency

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)
