Slugging Percentage Calculator (SLG)
Use our slugging percentage calculator to calculate SLG from singles, doubles, triples, home runs, and at-bats. Includes the SLG calculation formula, what slugging percentage means, and FAQs on what is a high slugging percentage.
What Is SLG Percentage?
Slugging percentage (SLG) is a baseball statistic that measures a hitter’s power by calculating total bases per at-bat.
Unlike batting average, slugging percentage gives extra weight to extra-base hits: doubles, triples, and home runs count for more total bases than singles.
A higher SLG percentage generally indicates more power and more extra-base hits per at-bat.
Slugging Percentage Equation
Slugging percentage is total bases divided by at-bats.
Each hit type contributes its base value.
At-bats must be greater than 0.
SLG is reported as a decimal (not a percent) in most baseball stats.
How to Calculate Slugging Percentage
- 1
Enter singles, doubles, triples, and home runs.
- 2
Enter at-bats (AB).
- 3
The calculator computes total bases and divides by at-bats to return SLG.
Frequently Asked Questions
Compute total bases: TB = 1B + 2×2B + 3×3B + 4×HR, then divide by at-bats: SLG = TB ÷ AB.
It measures total bases per at-bat, which is a simple way to describe hitting power and extra-base hit rate.
It depends on level and era, but higher SLG means more power. Comparing players within the same league and season is the fairest way to judge.
Despite the name, it’s usually reported as a decimal. You can multiply by 100 if you want a percent, but baseball stats typically keep it as a decimal.
Batting average treats all hits the same. Slugging percentage weights extra-base hits more because it uses total bases.
