WHIP Calculator
Calculate WHIP (Walks + Hits Per Innings Pitched) to evaluate pitcher effectiveness.
WHIP Formula
WHIP = (Walks + Hits) ÷ Innings Pitched
Measure of baserunners allowed per inning pitched. Lower is better. Independent of run support or defense quality.
WHIP Rating Scale
| WHIP | Rating | Quality |
|---|---|---|
| <0.90 | ⭐⭐⭐⭐⭐ | Hall of Fame caliber |
| 0.90–1.05 | ⭐⭐⭐⭐ | Exceptional (Cy Young contender) |
| 1.05–1.20 | ⭐⭐⭐ | Very Good (All-Star caliber) |
| 1.20–1.40 | ⭐⭐ | Average (MLB baseline) |
| 1.40–1.60 | ⭐ | Below Average |
| >1.60 | ❌ | Poor (likely needs optioning) |
Frequently Asked Questions
-
WHIP = (Walks + Hits) ÷ Innings Pitched. Measures how many baserunners (on walks and hits) a pitcher allows per inning. Lower WHIP = better pitcher. MLB average: ~3.3–3.4.
-
<1.00: Elite pitcher. 1.00–1.20: Very good. 1.20–1.40: Average. 1.40–1.60: Below average. >1.60: Poor. All-time greats: 0.86 (Mariano Rivera), 0.94 (Christy Mathewson).
-
WHIP = (Walks + Hits) ÷ Innings Pitched. Example: 80 walks + 140 hits = 220 baserunners. 200 innings pitched. WHIP = 220 ÷ 200 = 1.10.
-
Predicts runs allowed better than ERA. Pitcher control independent of defense quality. Walks show control; hits show stuff. Combined metric is comprehensive.
-
ERA counts runs allowed (defense-dependent). WHIP counts baserunners (pitcher control-dependent). WHIP is often more predictive of future ERA performance.
-
1 IP (inning pitched) = full inning. 1.1 IP = 1 and 1/3 innings. WHIP calculation uses decimal: 1.1 IP = 1.333 innings for math. Most baseball stats express as IP (not decimals).
-
Yes, and it indicates elite control. Only top-tier pitchers achieve sub-1.00 WHIP for full seasons. Historic masters: Rivera (0.86), Mathewson (0.94), Johnson (0.96).
-
Primary relief pitcher stat. Leagues score WHIP directly (lower = better points). Indicates pitcher consistency. Top WHIP pitchers are high draft value.
-
No. Singles and home runs count equally as hits. ERA and FIP account for outcome quality better. WHIP only measures baserunner volume.
-
Typically requires 50+ innings pitched for relief pitchers, 162+ innings for starters. Smaller sample sizes (early season) are volatile.
-
WHIP normalizes to per-inning basis, so it's directly comparable. 1.20 WHIP from 100 IP = same quality as 1.20 WHIP from 200 IP.
-
BB/9 + H/9 = WHIP × 9. WHIP is the combined metric of walk rate and hit rate. Both inform different aspects of control.
