Walks plus Hits per Inning Pitched, better known as WHIP, is a simple but telling metric that reveals how many baserunners a pitcher allows per inning.
By dividing the sum of walks and hits by the total innings pitched, you gain an immediate sense of efficiency on the mound.
Use this calculator to turn raw box-score totals into a tidy ratio and compare pitchers across games, seasons, or entire careers.
In addition to WHIP, another valuable statistic to consider is walks per nine innings explained, which provides insight into a pitcher’s control and ability to limit free passes.
A lower walks per nine innings indicates that a pitcher is not only effective at preventing hits but also excels at minimizing walks, enhancing their overall effectiveness in games.
By analyzing both WHIP and walks per nine innings, fans and analysts can gain a deeper understanding of a pitcher’s performance and value to their team.

WHIP FAQ
What does a good WHIP look like?
A WHIP below 1.10 is considered excellent, 1.10-1.30 is solid, and anything above 1.50 usually signals trouble keeping runners off base.
Can WHIP be negative?
No. Because walks, hits, and innings pitched are all non-negative numbers, the ratio cannot dip below zero.
Does WHIP include hit batters or errors?
WHIP counts only walks and hits.
Hit batters, errors, and runners reaching on interference or obstruction are not included.
Why use WHIP instead of ERA?
WHIP isolates how well a pitcher prevents base runners, removing the defensive and situational factors that can skew ERA.
How is WHIP different in youth leagues?
At lower levels innings are shorter and defensive miscues are more common, so WHIP values tend to run higher than in professional baseball.
