Slugging percentage (SLG) is a statistic that evaluates a player’s total hitting power. It is a numeric value ranging from 0 to 4, reflecting overall productivity at the plate. Note that walks and hit-by-pitches are not included in SLG calculations. This metric is commonly used for evaluating players, determining batting order, and comparing individual or team performance.

Suppose a batter has 125 at-bats with the following hits: 18 singles, 6 doubles, 1 triple, and 5 home runs. Let’s calculate SLG:
Given:
Apply the formula:
SLG = (18 + (2 × 6) + (3 × 1) + (4 × 5)) ÷ 125
SLG = 53 ÷ 125 = 0.424
This is how slugging percentage is calculated. For faster results, an online calculator can do the work instantly.
