On Base Percentage Calculator
Calculate on base percentage, the stat that measures how often a batter reaches base safely, which many analysts prize above batting average. The formula is hits plus walks plus hit by pitch, all divided by at bats plus walks plus hit by pitch plus sacrifice flies. Unlike batting average, on base percentage rewards drawing walks, so a patient hitter with a good eye can carry a high OBP even with a modest average. Enter hits, walks, times hit by pitch, at bats and sacrifice flies, and the tool sums the numerator and denominator, divides and shows the result in the standard .000 format. A mark around .340 is roughly league average and anything over .400 is elite. The calculation runs instantly in your browser and nothing you type is sent to a server.
