Knowing how to find on base percentage (OBP) for softball involves a formula that is not that difficult to find.  This is the same for softball and baseball.  Use the following steps in order to find on base percentage.

1. Know what statistics are not involved in this formula.  On base percentage measures how often a softball player reaches base.  However, the following statistics are not used: fielding errors, fielder's choice, dropped/uncaught third strike, catcher's interference, or fielder's obstruction.  These should not be included in a batter reaching base.
2. Use three statistics for the first half of the formula.  The top part of the division involves the following in the formula: hits, bases on balls (walks), and times hit by pitch.  Add these three numbers to get the value needed for the other half of the formula.
3. Use four statistics for the second half of the formula.  On base percentage is calculated with the following stats in the bottom part of the formula: at bats, bases on balls (walks), times hit by pitch, and sacrifice flies.  Add these numbers to get the value needed in the formula.
4. Divide the two numbers.  To get on base percentage, divide the result of the step two value by that of the step three value.
5. Use on base percentage as a statistic.  You will then be able to find a player's on base percentage for softball.  You can even add it to slugging average to find a player's on base plus slugging (OPS).

On base percentage remains an important statistic in softball. Anyone who plays or watches the game should know how to calculate it.
