Baseball Fielding Percentage (FPCT) Calculator



What is Fielding Percentage?

Fielding percentage is a baseball statistic used to put a fielder’s number of putouts and assists in comparison to the total number of opportunities they’ve had for putouts and assists.

It is intended to be a tool in measuring a fielder’s capability.

Critics of fielding percentage note that the statistic can be misleading – fielders who work harder to get to the ball can have a higher percentage of errors (therefore a lower fielding percentage) while at the same time being more effective for their team as they have a higher total number put outs and assists.  A hit that passes by a fielder does not reflect in their fielding percentage score, while one that they try for and get an error on does.

How to calculate FPCT

In Baseball, on fielding percentage is calculated as follows:

Fielding Percentage (FPCT) = (put outs + assists) / (put outs + assists + errors).


If a fielder has completed 317 put outs, 541 assists, and 27 errors, then:

317 + 541 is 858

317 + 541 + 27 is 885.

858 / 885 is 0.96949

Therefore, the fielder’s fielding percentage is 0.96949.

What counts as a “Put Out”?

A put out is any time a fielder catches a runner out.

Typically this is done by tagging a runner out, catching a ball and tagging a base, catching a third strike, catching a fly ball, or being the closest player to a runner who is called out for interference.

What counts as an Assist?

An assist is counted for each person who touches the ball after it has been hit and before a player is put out when a put out is claimed.

Even if the touch of the ball was unintentional, the assist is still recorded.

Only one assist per player per out recorded can be claimed.

In the event of an error, the assist is awarded if the putout would have occurred.

What counts as an Error?

An error is a fielder misplaying a ball in a manner that allows a batter or baseruner to advance one or more bases, or an at bat is allowed to continue after the batter should have been put out.
