WHIP Calculator
Evaluate Pitcher Efficiency (Walks + Hits per Inning)
What is WHIP in Baseball?
WHIP is one of the most important metrics for evaluating a pitcher\'s performance. Unlike ERA, which can be affected by unearned runs and team defense, WHIP focuses solely on how many baserunners a pitcher allows. By measuring walks and hits per inning, it provides a clear picture of how well a pitcher controls the strike zone and prevents opposing batters from reaching base.
How to Calculate WHIP
The calculation is simple and consistent across all levels of baseball:
WHIP = (Walks + Hits) / Innings Pitched
Example: If a pitcher allows 12 walks and 48 hits over 50 innings, their WHIP is (12 + 48) / 50 = 1.20.
WHIP Benchmarks & Standards
In Major League Baseball, WHIP standards have remained relatively consistent. A lower number indicates better performance. Here is the general scale used by scouts and analysts:
- Under 1.00 (Elite): Legendary control. Think prime Pedro Martinez or Clayton Kershaw.
- 1.00 - 1.20 (Great): A frontline starter or high-leverage closer.
- 1.20 - 1.40 (Average): A solid, reliable member of a pitching staff.
- Above 1.50 (Poor): Indicates too many baserunners, leading to higher stress innings and more runs allowed.
Why WHIP Matters
WHIP is widely used in fantasy baseball and advanced analytics because it is a "sticky" stat—meaning it tends to be more consistent year-over-year than ERA. A pitcher with a high ERA but a low WHIP is often considered a "bounce-back" candidate because they are keeping runners off base, but might be suffering from bad luck or poor defense behind them.

Frequently Asked Questions
What does WHIP measure in baseball?
WHIP stands for Walks plus Hits per Inning Pitched. It measures how many baserunners a pitcher allows on average for every inning they pitch. It is considered a better measure of a pitcher's raw effectiveness than ERA because it removes factors like team defense and luck.
How is WHIP calculated?
The formula for WHIP is: (Walks + Hits) / Innings Pitched. For example, if a pitcher allows 1 walk and 1 hit in 2 innings, their WHIP is (1 + 1) / 2 = 1.00.
What is a good WHIP for a pitcher?
In Major League Baseball, a WHIP under 1.00 is considered elite (Hall of Fame pace). A WHIP between 1.10 and 1.20 is very good, while the league average usually sits around 1.30.
Do hit-by-pitches (HBP) count toward WHIP?
No. Despite the name "Walks plus Hits," the official WHIP calculation only includes base hits and walks (bases on balls). Hit-by-pitches, errors, and fielder's choices do not count toward WHIP.
