SLG Calculator
Definition – What is Slugging Percentage?
SLG compares a batter’s bases earned in comparison to the number of times they have been at the plate.
A higher slugging percentage means the batter hits for total bases for each time at the plate.
Formula – How to calculate SLG
Slugging Percentage (SLG) = (1 base hits + (2 x 2 base hits) + (3 x 3 base hits) + (4 x home runs)) ÷ at bats.
Example
If a batter has been at bat 127 times and in that time has made: 20 1 base hits, 5 2 base hits, 1 3 base hit, and 4 home runs, then:
20, 1 base hits = 20 x 1 = 20.
5, 2 base hits = 5 x 2 = 10.
1, 3 base hit = 1 x 3 = 3.
4 home runs is 4 x 4 = 16.
Total bases earned is 20 + 10 + 3 + 16 = 49.
49 ÷ 127 at bats = 0.386
Therefore, the batter’s on slugging percentage is 0.386.
