On-Base Percentage vs Hits
How On-Base Percentage Is Calculated
Formula
OBP = (Hits + Walks + HBP) / (At Bats + Walks + HBP + Sac Flies)
OBP measures how often a batter reaches base. It is considered more valuable than batting average because it accounts for walks and hit-by-pitches.

Example Calculation
75 hits, 30 walks, 3 HBP, 250 at-bats, 4 sacrifice flies.
- 01Times on base = 75 + 30 + 3 = 108
- 02Plate appearances = 250 + 30 + 3 + 4 = 287
- 03OBP = 108 / 287 = 0.376
