Fielding Percentage Calculator
Enter a fielder's putouts, assists, and errors to get their fielding percentage (FPCT). Choose a position and the result is compared against MLB benchmarks so you can see at a glance whether the mark is elite, above average, average, or below average for that spot on the diamond. The step panel shows the full arithmetic and a reference table covers every position.
Formula
Worked example
A shortstop records 317 putouts, 541 assists, and 27 errors over a season. Successful plays = 317 + 541 = 858. Total chances = 858 + 27 = 885. FPCT = 858 / 885 = .969. The MLB average for shortstops is about .974, so this mark is slightly below average.
What fielding percentage measures
Fielding percentage (FPCT), also called fielding average, is the oldest and most widely reported defensive statistic in baseball. It measures the share of defensive chances a fielder handles cleanly, without committing an error. A total chance is any opportunity to make a play: a putout (the fielder records the out directly, such as catching a fly ball or receiving a throw at first base), an assist (the fielder touches the ball before the putout is made by someone else), or an error (a misplay where an ordinary effort should have retired the batter or held a runner). Divide the successful plays by the total chances and you have FPCT. A result of 1.000 means zero errors over the sample; lower values reflect error frequency.
Position-specific context matters
FPCT looks very different depending on where a player stands. First basemen and outfielders handle a higher proportion of routine catches, so their averages cluster near .990 to .998. Shortstops and third basemen field difficult ground balls and make long throws across their body, so their averages are lower - typically .965 to .980 - and a mark that looks poor at first base is actually solid at shortstop. Comparing FPCT across positions is misleading; always benchmark against the position average. This calculator provides MLB average, "good," and "elite" thresholds for every position so you can interpret the number in the right context.
The main limitation: range is invisible
FPCT only counts plays a fielder actually attempts. A slow or limited-range fielder who stays safe and never reaches difficult balls will record fewer total chances and may have a higher FPCT than an athletically gifted defender who gets to more balls and occasionally misplays one. The statistic does not penalize a fielder for the ball that rolled into the gap unchallenged, turning a clean out into a hit. This is why advanced metrics such as Defensive Runs Saved (DRS), Outs Above Average (OAA), and Ultimate Zone Rating (UZR) were developed: they credit the plays made relative to an average fielder at that position and penalize for balls not reached. FPCT is best used as a quick error-avoidance check rather than a complete measure of defensive value.
How scoring decisions affect FPCT
FPCT depends on official scorer rulings. A batted ball that passes a fielder without a legitimate play attempt is scored as a hit and does not affect FPCT at all. Only when a fielder makes a play and fails does the scorer award an error, lowering FPCT. Two fielders can see the same ball - one lets it go (no effect on FPCT), the other attempts the play and misses (error recorded) - and the aggressive fielder finishes the season with a lower FPCT despite clearly superior defensive instincts. Knowing this context helps coaches and analysts use FPCT alongside other metrics rather than in isolation.

Approximate modern-era MLB averages. Standards differ significantly by position: errors are far more common for infielders than outfielders or first basemen.
Frequently asked questions
What is a good fielding percentage in baseball?
It depends on the position. For a shortstop or third baseman, a FPCT of .975 or higher is solid and .985+ is excellent. For a first baseman, anything below .990 is below average and .998+ is elite. For outfielders, .990+ is good and .999 is not unusual for a full season. Always compare the result to the MLB average for the specific position rather than a single universal threshold.
What counts as a putout versus an assist?
A putout (PO) is credited to the fielder who directly records the out: the first baseman who catches a throw, the outfielder who catches a fly ball, or the catcher who tags a runner. An assist (A) is credited to any fielder who touches or throws the ball before a putout is made by someone else. On a standard ground ball to shortstop: the shortstop gets an assist, the first baseman gets a putout. A fielder can earn only one assist per out, but a catcher can earn a putout on a strikeout even without touching the ball (pitcher retires the batter on a swinging third strike).
How is total chances (TC) calculated?
Total chances equals putouts plus assists plus errors: TC = PO + A + E. It represents every opportunity a fielder had to make or influence a play, whether they succeeded or not. A high total-chances count at a given position generally means the fielder is active and positioned in the ball's path often, which is itself a sign of good range - even if it also exposes them to more errors.
What is the highest fielding percentage ever recorded in MLB?
Several players have finished seasons with a perfect 1.000 fielding percentage over a qualifying number of chances, particularly at less error-prone positions like first base and outfield. The 2013 Baltimore Orioles hold the single-season team fielding percentage record at .99104. Career FPCT records are harder to compare because older eras had lower overall averages due to differences in equipment, field quality, and scoring conventions.
Can I use FPCT to compare players at different positions?
No - at least not directly. A shortstop with a .975 FPCT is handling a harder job than a first baseman with the same mark. Position-neutral defensive comparisons require advanced metrics like Defensive Runs Saved (DRS) or Outs Above Average (OAA), which account for the number and difficulty of chances at each position. Use FPCT only within the same positional group.
Why does a great defensive player sometimes have a lower FPCT?
Range and FPCT can move in opposite directions. A highly athletic fielder who gets to more balls will also have more opportunities to make errors on difficult plays. A conservative fielder who avoids the hardest chances will record fewer total opportunities and may never err on those plays - because they never attempted them. FPCT rewards clean handling, not necessarily the volume or difficulty of plays attempted. This is the main reason analysts pair FPCT with range-based metrics.
