What is WHIP?
WHIP stands for Walks and Hits per Inning Pitched. It measures how many baserunners a pitcher allows per inning via walks and hits. It’s one of the most popular pitching metrics in baseball and softball, especially in fantasy leagues.
Because WHIP focuses on baserunners allowed, it’s a good indicator of a pitcher’s control and ability to limit traffic on the bases. Lower WHIP values are better.
WHIP formula
WHIP = (Walks + Hits) / Innings Pitched
- Walks (BB): Bases on balls issued by the pitcher.
- Hits (H): Singles, doubles, triples, and home runs allowed.
- Innings Pitched (IP): Total innings the pitcher has thrown.
By the standard definition, WHIP does not include hit-by-pitch (HBP), errors, or baserunners who reach on a fielder’s choice.
Handling partial innings
Baseball scoring uses a special notation for partial innings:
- 6.0 IP = 6 full innings (18 outs)
- 6.1 IP = 6 innings + 1 out (19 outs)
- 6.2 IP = 6 innings + 2 outs (20 outs)
In true decimal form, those are:
- 6.0 IP → 6.00 innings
- 6.1 IP → 6 + 1/3 ≈ 6.33 innings
- 6.2 IP → 6 + 2/3 ≈ 6.67 innings
Our calculator lets you enter full innings + outs so you don’t have to convert thirds of an inning to decimals yourself.
Example WHIP calculation
Suppose a pitcher has the following line:
- Walks (BB): 3
- Hits (H): 5
- Innings pitched: 7.2 (7 innings and 2 outs)
- Total baserunners = 3 + 5 = 8
- Convert 7.2 IP to true decimal: 7 + 2/3 ≈ 7.67 innings
-
Compute WHIP:
WHIP = 8 ÷ 7.67 ≈ 1.04
A WHIP of about 1.04 is excellent.
How to interpret WHIP
Exact benchmarks vary by league and era, but for most competitive adult leagues:
| WHIP | Interpretation |
|---|---|
| ≤ 1.00 | Elite – very few baserunners allowed |
| 1.01 – 1.20 | Very good – strong command and contact management |
| 1.21 – 1.35 | Average – typical starter or reliever |
| 1.36 – 1.50 | Below average – frequent traffic on the bases |
| ≥ 1.51 | Poor – high risk of runs allowed |
WHIP vs ERA
ERA (Earned Run Average) measures how many earned runs a pitcher allows per 9 innings, while WHIP measures how many baserunners they allow per inning via walks and hits.
- WHIP is often more stable and less affected by defense and luck.
- ERA can fluctuate more due to errors, sequencing, and bullpen support.
Analysts and fantasy managers typically use both metrics together: WHIP to gauge control and baserunner prevention, ERA to see how many of those baserunners actually score.
Frequently asked questions
Does WHIP include hit-by-pitch (HBP)?
No. By the standard definition, WHIP only counts walks and hits. Hit-by-pitch, errors, and fielder’s choices are excluded.
Is WHIP useful for relievers?
Yes. WHIP is especially helpful for relievers because it focuses on baserunners allowed per inning, regardless of role. Just be aware that small sample sizes can make any stat more volatile.
Can I use WHIP for softball?
Absolutely. The same formula applies in softball: WHIP = (walks + hits) / innings pitched. Just make sure you’re using the correct innings and stat definitions for your league.
