How to Find Out an On-Base Percentage

The baseball statistic on-base percentage accounts for not only the number of hits a batter gets during a season, but also walks and hit by pitches. This number indicates a true measure of a player's offensive worth by showing how often the batter reaches base safely over the course of the year. This number is generally about .50 higher than a player's batting average, with more conservative batters having an OBP even greater than their BA because they tend to walk more.

Instructions

    • 1

      Add up the total number of hits, walks and hit by pitches the player has during the season.

    • 2

      Total the number of at-bats, sacrifice flies, hit by pitches and walks.

    • 3

      Divide the first number by the second number to calculate the on-base percentage.
