WHIP Calculator
Definition – What is Walks and Hits per Inning Pitched (WHIP)?
WHIP shows walks and hits allowed for each inning pitched. A lower number is considered better.
It is an alternative to the more popular Earned Run Average. Unlike ERA, WHIP shows pitcher performance regardless of fielding performance as it does not include errors and unearned runs.
Formula – How to calculate WHIP
WHIP = (Walks + Hits) ÷ (Innings Pitched + (Outs (Partial Innings) Pitched / 3))
Example
If a pitcher has allowed 190 hits and 43 walks over 202 innings and 1 out, then:
WHIP = (190 + 43) ÷ (202 + (1/3))
WHIP = 233 ÷ 202.333333
WHIP = 1.152
On an average inning, this pitcher allows a combined 1.152 walks and hits.
