WHIP Calculator: Walks Plus Hits per IP
This WHIP calculator works out a pitcher's walks plus hits per inning pitched, one of the best quick measures of how many runners a pitcher allows. Enter walks, hits and innings pitched (6.1 means 6⅓ innings and 6.2 means 6⅔, the way box scores show it), and add earned runs and strikeouts to also get ERA, K/9, BB/9, H/9 and strikeout-to-walk ratio. Choose 9 innings for baseball or 7 for softball, and see how the WHIP rates against typical MLB levels.

Frequently asked questions
How is WHIP calculated?
WHIP = (walks + hits) ÷ innings pitched. A pitcher with 40 walks and 150 hits in 180 innings has a WHIP of 190 ÷ 180 = 1.06.
What is a good WHIP?
In MLB, under 1.00 is excellent, about 1.10 is very good, 1.30 is about average and above 1.40 is below average.
What does 6.2 innings mean?
It means 6 innings plus 2 outs, or 6⅔ innings. Each out is one-third of an inning, so .1 = ⅓ and .2 = ⅔.
Do hit batters count in WHIP?
No. The standard WHIP counts only walks and hits. Hit by pitch, errors and fielder's choice are left out.
How is ERA different from WHIP?
ERA counts earned runs per 9 innings, while WHIP counts base runners per inning. WHIP is less affected by defense and luck with runners on base.
