Fielding percentage is the oldest defensive statistic in baseball. It shows how reliably a player makes plays, though it doesn’t account for range – a fielder who reaches fewer balls can still post a high percentage.

Inputs explained
| Field | What to enter |
|---|---|
| Putouts | A number |
| Assists | A number |
| Errors | A number |
What each result means
- Total chances = [Putouts] + [Assists] + [Errors]
- Fielding percentage = ([Putouts] + [Assists])÷([Putouts] + [Assists] + [Errors])
- As a percentage = ([Putouts] + [Assists])÷([Putouts] + [Assists] + [Errors])×100
Example values
How the main result changes when Putouts changes and everything else stays at the example values above:

| 280 | 0.983 |
| 350 | 0.985 |
| 420 | 0.986 |
| 560 | 0.988 |
Formula
FPCT = (PO + A) ÷ (PO + A + E)
Worked example
Inputs — Putouts: 280; Assists: 420; Errors: 12.
Results — Total chances = 712; Fielding percentage = 0.983; As a percentage = 98.31 %.
