What Is Slugging Percentage?
Updated Sports & Activities
The formula
- SLG = Total Bases / At-Bats
- Total bases = (1 x singles) + (2 x doubles) + (3 x triples) + (4 x home runs)
Example: in 10 at-bats, a batter hits a single, a double, and a home run. Total bases = 1 + 2 + 4 = 7. SLG = 7 / 10 = .700.
How to read it
| SLG | Roughly |
|---|---|
| .400 | below average |
| .450 | solid |
| .500+ | very good power |
| 4.000 | theoretical max (a home run every at-bat) |
Slugging vs. batting average: batting average asks "how often do you get a hit?" Slugging asks "how many bases do you get per at-bat?" A singles hitter and a slugger can share the same average but very different SLG.
Related: OPS = on-base percentage + slugging percentage, a popular all-in-one hitting stat. Slugging only counts hits (walks don't add bases here), which is why analysts pair it with on-base numbers.
