FIP (Fielding Independent Pitching) Calculator

Calculate FIP











Formula

The formula to calculate the Fielding Independent Pitching (FIP) is:

\[ FIP = \frac{(13 * HR) + (3 * (BB + HBP)) - (2 * K)}{IP} + C \]

What is FIP (Fielding Independent Pitching)?

Fielding Independent Pitching (FIP) is a metric in baseball that measures a pitcher’s effectiveness at preventing home runs, walks, hit by pitches, and causing strikeouts, which are the four outcomes that a pitcher has the most control over. It is designed to remove the influence of the team’s fielding ability on the pitcher’s performance, hence the term “fielding independent.”

The formula for FIP is \((13*HR+3*(BB+HBP)-2*K)/IP\), plus a constant (usually around 3.2) to put it on the same scale as earned run average (ERA). A lower FIP indicates a better performance by the pitcher, independent of the fielding behind them. This metric is often used in sabermetrics, the empirical analysis of baseball, to evaluate a pitcher’s true skill level.

Example Calculation

Let's assume the following values:

Using the formula to calculate the FIP:

\[ FIP = \frac{(13 * 10) + (3 * (30 + 5)) - (2 * 150)}{200} + 3.2 = \frac{130 + 105 - 300}{200} + 3.2 = \frac{-65}{200} + 3.2 = -0.325 + 3.2 \approx 2.88 \]

The Fielding Independent Pitching (FIP) is approximately 2.88.
