Enter all but one of the HR, BB, HBP, K, IP, and constant into the calculator to determine the FIP statistic; this calculator can also evaluate any of the variables given the others are known.
Fip (Fielding Independent Pitching) Formula
The following formula is used to calculate the Fielding Independent Pitching (FIP) statistic:
FIP = ((13 * HR) + (3 * (BB + HBP)) - (2 * K)) / IP+C
Variables:
- FIP is the Fielding Independent Pitching statistic
- HR is the number of home runs allowed
- BB is the number of walks issued
- HBP is the number of batters hit by pitch
- K is the number of strikeouts
- IP is the number of innings pitched
- constant is a constant value typically added to the formula to normalize the statistic
To calculate the FIP, multiply the number of home runs allowed by 13, add the sum of 3 times the sum of walks issued and batters hit by pitch, subtract 2 times the number of strikeouts. Divide the result by the number of innings pitched and add the constant value.
What is a 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.
How to Calculate Fip (Fielding Independent Pitching)?
The following steps outline how to calculate the Fielding Independent Pitching (FIP) ratio.
- First, determine the number of home runs allowed (HR).
- Next, determine the number of walks allowed (BB).
- Next, determine the number of hit by pitches (HBP).
- Next, determine the number of strikeouts (K).
- Next, gather the formula from above = FIP = ((13*HR)+(3*(BB+HBP))-(2*K))/IP + constant.
- Finally, calculate the Fielding Independent Pitching (FIP) ratio.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Number of home runs allowed (HR) = 10
Number of walks allowed (BB) = 20
Number of hit by pitches (HBP) = 5
Number of strikeouts (K) = 100
Innings pitched (IP) = 150
Constant = 3.2
