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.

Benchmarks

  • .300: Below average
  • .340: League average
  • .370+: Very good
  • .400+: Elite

    75 hits, 30 walks, 3 HBP, 250 at-bats, 4 sacrifice flies.

    3. 03OBP = 108 / 287 = 0.376
