⚾ WHIP Calculator

Determine how many baserunners a pitcher allows per inning pitched.

Use .1 for one out and .2 for two outs (baseball notation).

How to Use This Calculator

1

Record Hits & Walks

Use season totals or a single game line for hits and walks allowed.

2

Enter Innings Pitched

Convert outs to baseball decimals (.1 and .2) before entering.

3

Calculate WHIP

Press the button to see WHIP and an automatic evaluation band.

4

Compare to Benchmarks

Use the rating to gauge whether the pitcher is elite, average, or needs improvement.

Formula

WHIP = (Walks + Hits) ÷ Innings Pitched

WHIP captures how many baserunners a pitcher allows per inning. Fewer baserunners generally mean fewer runs, making WHIP a quick proxy for command and contact management.

Variables

  • Walks (BB): Free passes issued
  • Hits (H): All hits allowed
  • Innings Pitched (IP): Outs recorded ÷ 3 (use baseball decimals)

Example

Pitcher allows 152 hits and 45 walks in 205.1 IP. Convert 205.1 → 205.33 innings. WHIP = (152 + 45) ÷ 205.33 = 0.96.

Understanding WHIP

WHIP has become a staple fantasy baseball stat because it directly translates to pitcher efficiency. Lower WHIPs limit rallies and high-leverage situations.

Benchmark Guide

  • < 1.00: Truly elite
  • 1.00 – 1.10: Top-tier starter
  • 1.10 – 1.25: Above average
  • 1.25 – 1.35: League average
  • > 1.35: In trouble—too many baserunners

Improvement Tips

  • Focus on first-pitch strikes to get ahead in the count.
  • Refine secondary pitches to induce weak contact.
  • Improve command to avoid free passes and reduce traffic.

Frequently Asked Questions

Does WHIP include hit batters?

Standard WHIP excludes hit batsmen. Some analysts use a modified WHIP (sometimes called WHIP+) that includes HBPs for a fuller picture.

Why use baseball decimals for innings?

Scorekeepers note partial innings as .1 (one out) or .2 (two outs). The calculator converts these to decimal innings automatically.

How does WHIP differ from ERA?

ERA measures runs allowed, while WHIP counts base runners. A pitcher can have a low WHIP but a higher ERA if hits come in clusters or if home runs inflate runs allowed.

Is WHIP predictive?

WHIP is fairly stable year-to-year because strikeout and walk skills are repeatable. Pair it with K/BB for deeper analysis.

Can relievers have lower WHIPs?

Yes. High-leverage relievers who face fewer batters and rely on strikeouts often post WHIPs well under 1.00.
