On-base percentage  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.

OBP is basically measuring the amount of times a hitter does not make an out. 


On-base percentage is calculated using this formula:
OBP = \frac{H+BB+HBP}{AB+BB+HBP+SF}
