WHIP (Walks + Hits per Innings Pitched) is a key baseball statistic that measures how many baserunners a pitcher allows per inning. It is considered one of the best indicators of pitcher effectiveness. The formula is: WHIP = (Walks + Hits) / Innings Pitched. A lower WHIP means fewer baserunners and generally better pitching performance. At the MLB level, a WHIP below 1.00 is elite, 1.00-1.20 is excellent, 1.20-1.30 is good, and above 1.50 is considered poor. This calculator also handles partial innings by recording additional outs.

WHIP is calculated as (Walks + Hits) / Innings Pitched. For example, if a pitcher allows 2 walks and 5 hits in 7 innings, their WHIP is (2 + 5) / 7 = 1.00.
In Major League Baseball, a WHIP below 1.00 is elite, 1.00-1.20 is excellent, 1.20-1.30 is good, 1.30-1.40 is average, and above 1.50 is considered poor.
WHIP measures how many baserunners a pitcher allows per inning. Since preventing baserunners directly reduces scoring opportunities, WHIP is one of the most reliable predictors of pitcher success.
