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.
