Enter a pitcher's Hits Allowed, Walks Allowed, and Innings Pitched to calculate their WHIP (Walks plus Hits per Inning Pitched). You'll get the WHIP value along with a quality rating — from Elite to Poor — so you can instantly benchmark any pitcher's performance against MLB standards.

WHIP stands for Walks plus Hits per Inning Pitched. It is a sabermetric statistic that measures how many baserunners a pitcher allows per inning. It is one of the most widely used metrics for evaluating a pitcher's effectiveness at preventing batters from reaching base.
WHIP is calculated using the formula: WHIP = (Hits Allowed + Walks Allowed) / Innings Pitched. For example, if a pitcher allows 190 hits and 43 walks over 202.1 innings, their WHIP is (190 + 43) / 202.333 ≈ 1.152.
A WHIP below 1.00 is considered elite and is rare even among top MLB starters. A WHIP between 1.00 and 1.15 is excellent, 1.15–1.30 is above average, 1.30–1.50 is average, and anything above 1.50 is considered below average or poor.
In baseball, partial innings are recorded in thirds. Use .1 to represent one out recorded and .2 to represent two outs recorded in a partial inning. For example, 6.2 means 6 full innings plus 2 outs. The calculator automatically converts this notation into the correct decimal value for the formula.
While ERA (Earned Run Average) measures runs allowed and can be influenced by fielding and luck, WHIP focuses purely on a pitcher's ability to prevent baserunners regardless of what happens after they reach base. This makes WHIP a more direct reflection of a pitcher's control and effectiveness.
Addie Joss holds the all-time career WHIP record at approximately 0.9678 for pitchers with enough innings to qualify. Among modern era pitchers, Pedro Martínez posted one of the most famous single-season WHIPs at 0.7373 in 2000, widely regarded as one of the greatest pitching seasons ever.
No. WHIP only counts hits (H) and walks (BB). Hit batsmen (HBP) and runners who reach base on errors are not included in the WHIP calculation. This keeps the statistic focused specifically on outcomes directly resulting from the pitcher's actions — surrendering hits or issuing walks.
