What is Slugging Percentage?

Slugging Percentage (SLG) is a baseball statistic that measures a batter’s power and productivity at the plate. Unlike batting average, which only accounts for hits, slugging percentage assigns different values to hits based on the number of bases reached. It’s calculated by dividing total bases by at-bats.

The formula is:

SLG = Total Bases ÷ At Bats

Where Total Bases = (1 × Singles) + (2 × Doubles) + (3 × Triples) + (4 × Home Runs)

Understanding Slugging Percentage Values

SLG Range	Interpretation
.600+	Excellent
.500-.599	Very Good
.450-.499	Above Average
.400-.449	Average
.350-.399	Below Average
Below .350	Poor

A slugging percentage of .500 means a player averages one base per two at-bats, which is considered very good in MLB. League average typically falls around .400-.420.

Example Calculation

For a player with:

300 At-Bats
80 Singles
25 Doubles
5 Triples
15 Home Runs

Total Bases = (80 × 1) + (25 × 2) + (5 × 3) + (15 × 4) = 80 + 50 + 15 + 60 = 205
Slugging Percentage = 205 ÷ 300 = .683

This would be considered an excellent slugging percentage in professional baseball.

 FAQ

How accurate is slugging percentage at measuring a player's offensive value?

Slugging percentage is good at measuring power but doesn't account for walks or other ways of reaching base. It's more accurate than batting average but less comprehensive than OPS (On-base Plus Slugging) or wOBA (weighted On-base Average), which consider all aspects of offensive contribution.
What's a good slugging percentage in baseball?

In Major League Baseball, a slugging percentage of .450 or higher is considered above average, .500+ is excellent, and .600+ is elite. The league average typically hovers around .400-.420, though this can vary slightly by season.
How does slugging percentage differ from batting average?

Batting average only counts whether a hit occurred (hits divided by at-bats), while slugging percentage accounts for the type of hit by assigning more value to extra-base hits. This provides better insight into a player's power and overall offensive impact.
Can a player have a slugging percentage higher than 1.000?

Yes, a player can have a slugging percentage higher than 1.000, though it's extremely rare and usually only sustainable over short periods. This would mean the player is averaging more than one base per at-bat, typically by hitting many extra-base hits, particularly home runs.
Is slugging percentage used in fantasy baseball scoring?

Yes, slugging percentage is commonly used in fantasy baseball, especially in points leagues and sabermetric-focused formats. Many fantasy platforms use SLG as a category or incorporate it into scoring systems that reward players for extra-base hits.
