Enter a fielder's putouts, assists, and errors to calculate their Fielding Percentage (FPCT). You'll get the fielding percentage along with total chances and a breakdown of how each component contributes — a quick way to assess any defensive player's reliability in baseball.

Fielding percentage (FPCT), also called fielding average, is a baseball statistic that measures how often a defensive player successfully handles a batted or thrown ball. It's expressed as a decimal between 0 and 1, where a higher value indicates fewer errors relative to total chances. A perfect fielding percentage of 1.000 means no errors were committed.
The formula is: FPCT = (Putouts + Assists) / (Putouts + Assists + Errors). First, add putouts and assists to get successful chances. Then divide that sum by total chances, which includes errors. For example, a fielder with 1,489 putouts, 496 assists, and 33 errors has an FPCT of (1,489 + 496) / (1,489 + 496 + 33) = 0.984.
A 'chance' is any opportunity a fielder has to record a putout or an assist. Total chances = putouts + assists + errors. Passed balls for catchers are not included. Every ball the fielder is expected to handle cleanly counts as a chance, whether or not they succeed.
It depends on the position. First basemen and outfielders typically post very high percentages (above .990), while shortstops and third basemen face more difficult plays and average around .970–.980. In Major League Baseball, a fielding percentage above .980 is generally considered excellent for most positions.
A higher FPCT indicates fewer errors, but it doesn't capture range. A fielder who only attempts easy plays can maintain a perfect FPCT while a more aggressive fielder with greater range might commit more errors. This is why FPCT has limitations and is often used alongside range-based metrics like Range Factor or Defensive Runs Saved.
A player who covers more ground attempts balls that other fielders wouldn't even reach. More difficult attempts naturally lead to more potential errors, lowering their FPCT. Meanwhile, a fielder with limited range sticks to easy plays, artificially inflating their percentage. This is a well-known limitation of the fielding percentage statistic.
No. Fielding percentage only measures what happens on balls a fielder actually touches — it says nothing about how many balls they can reach. Range Factor (RF) or Ultimate Zone Rating (UZR) are better metrics for measuring a fielder's range and overall defensive value.
Yes. You simply sum the putouts, assists, and errors for all players on the team and apply the same formula: Team FPCT = (Total Putouts + Total Assists) / (Total Putouts + Total Assists + Total Errors). This gives a snapshot of the team's collective defensive reliability.
