About the Fielding Percentage Calculator
The fielding percentage calculator measures how often a fielder handles the ball cleanly. It divides successful plays (putouts plus assists) by total chances (putouts, assists and errors). It is simple and widely reported, but it does not credit range — a fielder who reaches more balls can make more errors — so advanced metrics are often used as well.
How to use it
- 1Enter putouts.
- 2Enter assists.
- 3Enter errors and press Calculate.
Worked example
250 putouts, 30 assists and 5 errors give (250 + 30) ÷ 285 = .982.
How it works
Formula
FP = (Putouts + Assists) ÷ (Putouts + Assists + Errors)
Common use cases
- Comparing defensive reliability
- Season stat summaries
- Coaching youth fielders
