On Base Percentage Calculators or OBP Calculators are very useful tools for the everyday Baseball and Softball player. Since this is one of each sports most complex statistics, it's nice to have software that will do all of the work for you.
The equation for On Base Percentage is as follows:
On Base Percentage = (Hits + Walks + Hit By Pitch)/(At Bats + Walks + Hit By Pitch + Sacrifice Flies)
I've found that spreadsheets are the simplest way to store these statistics, but there aren't any great templates out there to start with. I've stopped using spreadsheets and I've started using TomorrowsPro.com. They have an easy to use interface and they store your stats for you. I enter my stats after every game and all of my stats are automatically re-calculated for me.
I also convinced my coach to use this site and now the whole team has stats on there and we can see how we are doing compared to the team averages. The site also offers graphs of your stats so you can see how you are doing as the seasons progress.
I hope you enjoy this information and find it useful. Good luck with your Baseball/Softball stats!
