Slugging percentage

Slugging percentage (abbreviated SLG) is the number of total bases divided by number of at bats.

Its formula is ([Singles] + [Doubles x 2] + [Triples x 3] + [Home Runs x 4])/At Bats

At bats are different than plate appearances.

An equivalent formula is ([Hits] + [Doubles] + [Triples x 2] + [Home Runs x 3])/At Bats

This formula is not as intuitive, but is often more convenient, as singles are often not given (although they could easily be found).

Singles can be figured fom the following equation because they are simply hits that are not for extra bases: (Hits - [Doubles + Triples + Home Runs])
