How it works
WHIP — walks plus hits per inning pitched — is one of the most important statistics for evaluating a baseball pitcher, and this calculator computes it. You enter the walks and hits the pitcher has allowed and the innings pitched, and it returns the WHIP. The calculation adds walks and hits, then divides by innings pitched, giving the average number of baserunners the pitcher allows each inning. Because runners on base lead to runs, WHIP is a strong indicator of a pitcher's effectiveness at preventing scoring opportunities — it captures both control (avoiding walks) and the ability to prevent hits. Lower is better: an elite WHIP is around 1.00 or below, very good is 1.00 to 1.10, above average around 1.10 to 1.25, average near 1.30, and above 1.50 is poor. Unlike ERA, which can be affected by defense and sequencing, WHIP focuses purely on how many runners a pitcher puts on base via walks and hits, making it a cleaner measure of control and command. Note that hit batters are not included in the standard WHIP formula, and innings pitched can include partial innings (like 100.1 or 100.2 for one or two outs). This calculator is useful for fans, fantasy baseball players, and analysts. Enter the walks, hits, and innings pitched to calculate WHIP.
WHIP = (walks + hits) ÷ innings pitched
WHIP stands for walks plus hits per inning pitched. It is the sum of walks and hits allowed divided by the number of innings pitched, measuring how many baserunners a pitcher allows per inning. A lower WHIP means fewer runners and better performance.

Frequently asked questions
How do you calculate WHIP?
Add the walks and hits a pitcher has allowed, then divide by innings pitched. A pitcher with 30 walks and 90 hits over 100 innings has a WHIP of (30 + 90) divided by 100, which is 1.200. WHIP measures how many baserunners the pitcher allows per inning, so lower values are better.
What is a good WHIP?
Lower is better. An elite WHIP is around 1.00 or below, very good is 1.00 to 1.10, above average about 1.10 to 1.25, league average near 1.30, and anything above 1.50 is considered poor. Because it measures baserunners allowed per inning, a low WHIP reflects strong control and hit prevention.
Why is WHIP a useful stat?
WHIP directly measures how many runners a pitcher allows via walks and hits, and runners are what lead to runs. It captures both control and the ability to limit hits in one number. Unlike ERA, it is less influenced by defense, ballpark, and the sequencing of events, making it a cleaner gauge of a pitcher's command.
Does WHIP include hit batters?
No. The standard WHIP formula counts only walks and hits, not hit batsmen, even though a hit batter also puts a runner on base. This is a minor limitation of the stat. If you want a fuller picture of baserunners allowed, you can look at on-base metrics against the pitcher, but standard WHIP uses just walks and hits.
How are partial innings counted?
Innings pitched can include partial innings shown as decimals: .1 means one out (one-third of an inning) and .2 means two outs (two-thirds). So 100.2 innings is 100 and two-thirds. When entering innings pitched, convert these thirds to decimals — .1 is about 0.33 and .2 is about 0.67 — for the most accurate WHIP, or enter the exact decimal.
