How do you calculate OBP?

Answer 1

OBP = On Base Percentage

1) Take a batter's number of plate appearances and subtract the number of sacrifices (bunts) the batter has.

2) Add the batter's number of base hits, walks, and hit by pitch.

3) Divide the value in 2) by the value in 1)

EXAMPLE: The batter has 600 plate appearance and 2 sacrifices. The batter has 160 base hits, 70 walks, and 4 hit by pitch.

A) Subtract the number of sacrifices from the number of plate appearances (600 - 2 = 598).

B) Add base hits, walks, and hit by pitch (160 + 70 + 4 = 234).

C) Divide 234 by 598 (234 / 598 = .391)

The batter's OBP is .391.
