Fielding Percentage Calculator

Enter the total number of putouts, assists, and errors into the calculator below to determine the fielding percentage of a baseball player. Field percentage is a measure of how often a baseball player correctly fields a batted ball.

Fielding Percentage Formula

The following formula is used by the calculator above to determine the fielding percentage of a baseball player.

FP = (p + a) / (p + a + e)

  • Where FP is the fielding percentage (%)
  • a is the number of assists
  • p is the number of putouts
  • e is the number of errors.

In essence, this is the total number of putouts and assists divided by the total number of attempts. This makes since conceptually, because any play that results in a putout or assist is the correct play. Any decision that ends in an error, is obviously not.

Fielding percentage is only one of many statistics used in baseball. It is not perfect. For example, if a player tries to throw home to get a runner out, but is overthrown, that is an error. Instead another player simply throws to second base and stops a runner from advancing. If the game was tied, and that was the last run needed, then the correct play is to throw home. Yet the player that threw to second has a higher fielding percentage.
