FIP Calculator

Calculate Fielding Independent Pitching (FIP) to evaluate pitcher performance independent of fielding support. FIP focuses on outcomes pitchers can directly control: home runs, walks, hit batters, and strikeouts.

Pitching Statistics

Enter pitching statistics to calculate Fielding Independent Pitching (FIP)

Home Runs Allowed (HR)

Home runs allowed by the pitcher

Walks (BB)

Base on balls issued by the pitcher

Hit By Pitch (HBP)

Batters hit by pitch

Strikeouts (K)

Strikeouts recorded by the pitcher

Innings Pitched (IP)

Total innings pitched (e.g., 145.2)

FIP Constant (cFIP)

Scaling constant (~3.1-3.2)

Decimal Precision

Advanced Mode

Calculate custom cFIP from league stats

Formula: FIP = (13×HR + 3×(BB+HBP) - 2×K) ÷ IP + cFIP

Lower FIP indicates better pitcher performance

Understanding FIP

What is FIP?

Fielding Independent Pitching (FIP) evaluates a pitcher's performance based only on outcomes they can directly control: home runs, walks, hit batters, and strikeouts. It removes the influence of fielding and luck.

FIP vs ERA Comparison

FIP ≈ ERA: Neutral defense/luck
FIP < ERA: Defense may have hurt pitcher
FIP > ERA: Defense may have helped pitcher

Sample Calculation

Example: Pitcher Statistics

HR: 21, BB: 55, HBP: 13

K: 235, IP: 145, cFIP: 3.214

Calculation:

Numerator = 13×21 + 3×(55+13) - 2×235 = 7

FIP = 7 ÷ 145 + 3.214

FIP = 3.26

Note: Average FIP is typically around 4.20, varying by season and league.
