The On Base Percentage Calculator (OBP Calculator) is used to calculate the on base percentage (abbreviated OBP).
In baseball statistics, on base percentage (OBP) is a measure of how often a batter reaches base for any reason other than a fielding error, fielder’s choice, dropped/uncaught third strike, fielder’s obstruction, or catcher’s interference. On base percentage is sometimes referred to as on-base average, as the statistic is rarely presented as a true percentage.
On-base percentage is calculated using the following formula, where H is Hits, BB is Bases on Balls (Walks), HBP is times Hit By a Pitch, AB is At bats, and SF is Sacrifice Flies.
OBP = (H + BB + HBP) / (AB + BB + HBP + SF)
