Fielding Independent Pitching Calculator

Calculate fielding independent pitching (FIP) for baseball players

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 cFIP from league stats

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

Lower FIP indicates better pitcher performance

FIP Calculator: What It Is and How It Works

The FIP Calculator evaluates a pitcher’s Fielding Independent Pitching (FIP), a metric focusing only on outcomes the pitcher controls: home runs allowed (HR), walks (BB), hit-by-pitch (HBP), strikeouts (K), and innings pitched (IP). Formula: FIP = ((13 × HR) + (3 × (BB + HBP)) − (2 × K)) ÷ IP + C. C is a league constant to scale FIP similar to league-average ERA.

How to Use the Calculator

Enter Home Runs Allowed (HR)

Total home runs allowed.

Enter Walks (BB)

Total walks issued.

Enter Hit-by-Pitch (HBP)

Number of batters hit.

Enter Strikeouts (K)

Total strikeouts recorded.

Enter Innings Pitched (IP)

Total innings pitched.

Example Calculations

Example 1

HR: 20, BB: 50, HBP: 5, K: 200, IP: 180 → FIP ≈ 3.35

Example 2

HR: 10, BB: 30, HBP: 2, K: 150, IP: 120 → FIP ≈ 2.95

Example 3

HR: 15, BB: 40, HBP: 3, K: 180, IP: 160 → FIP ≈ 3.20

Example 4

HR: 25, BB: 60, HBP: 4, K: 210, IP: 200 → FIP ≈ 3.50

Frequently Asked Questions

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.
