Slugging percentage (SLG) calculator
Slugging percentage measures a hitter's power by total bases per at-bat: SLG = (1B + 2·2B + 3·3B + 4·HR) ÷ AB. Unlike batting average, it weights extra-base hits, so a slugger who hits doubles and homers scores far higher than a singles hitter.

Frequently asked questions
How does the Slugging percentage (SLG) calculator work?
It takes Singles (1B), Doubles (2B), Triples (3B), Home runs (HR) and At-bats (AB) and derives Slugging percentage (SLG) and Total bases (TB) from them. The calculation is live as you type, so the result updates on every change.
Which values does the calculator ask for?
5 values: Singles (1B), Doubles (2B), Triples (3B), Home runs (HR) and At-bats (AB). Nothing else is required — no account, no file upload.
What does a typical calculation look like?
With Singles (1B) = 15, Doubles (2B) = 5, Triples (3B) = 2, Home runs (HR) = 3 and At-bats (AB) = 100, the calculator returns Slugging percentage (SLG) = .430 and Total bases (TB) = 43. Those figures come from running this exact tool, so you can reproduce them by entering the same values.
How much does the result change with different inputs?
It moves a lot. Using Singles (1B) = 30, Doubles (2B) = 10, Triples (3B) = 4, Home runs (HR) = 6 and At-bats (AB) = 200 instead, Total bases (TB) goes from 43 to 86 — which is why it is worth testing a few scenarios rather than trusting a single figure.
What does it give for smaller values?
Scaled down to Singles (1B) = 8, Doubles (2B) = 3, Triples (3B) = 1, Home runs (HR) = 2 and At-bats (AB) = 50, Total bases (TB) comes out at 25. The relationship is worth checking at both ends before you rely on a single result.
When would I actually use this?
Running a league or a tournament: how many fixtures a format produces, how the table resolves ties, and what a team still needs to qualify.
What is the most common mistake?
Assuming tie-breaks work the same everywhere. Goal difference, head-to-head and goals scored are applied in a different order by nearly every competition, and the order decides the table.
What is the difference between the Slugging percentage (SLG) calculator and the OPS (on-base plus slugging) calculator?
This one returns Total bases (TB); the OPS (on-base plus slugging) calculator returns On-base percentage (OBP) and OPS. That is the whole difference — open the one whose figure you need.
Is there a tool for the next step?
Basketball rebound percentage (TRB%) calculator is the closest one after this: Estimate the percentage of available rebounds a player grabbed while on the court (TRB%).
What else is worth having open alongside it?
