Formulas

AVG = H ÷ AB OBP = (H + BB + HBP) ÷ (AB + BB + HBP + SF)

Example

150 hits in 500 at-bats, 60 walks, 5 HBP, 5 sacrifice flies:

  • AVG = .300
  • OBP = 0.377

On-base percentage — how often a batter reaches base by a hit, walk or hit by pitch.

What is a good batting average?

.300 or higher is excellent in professional baseball; around .250 is roughly average.
