How do you calculate slugging percentage?

It's total bases divided by the number of at-bats, and you usually do it to the third decimal point.



This page also has a calculator that does the math for you.

Add the total bases and divide by at bats. (single- one base, double- 2 bases, etc.) Here's the "official" formula



SLG = (1B + (2 x 2B) + (3 x 3B) + (4 x HR))/ AB



Note:



1B- Base Hits

2B- Doubles

3B- Triples

HR- Home Run

AB- At Bats

SLG- Slugging Percentage



So know this



Number of base hits

Doubles x 2

Triples x 3

Home Runs x 4



Add those numbers together and divide it by At bats.





Example:



A Batter has these stats



10 Base Hits

4 Doubles

1 Triple

3 Home Runs

35 At Bats



So do the math

Number of base hits: 10

Doubles x 2: 8

Triples x 3: 3

Home Runs x 4: 12

Add those numbers: 33

Divide by at bats (35)



33 divided by 35= .943

total bases divided by at bats.How do you calculate slugging percentage?
Total bases by at bats, i.e. a home run it's 4/1=4.000
Step One

Add up all official at bats. Do not include those at bats that resulted in a walk, sacrifices or hit by pitch.

Step Two

Add up total bases. Total bases are how many bases you reached in all the times you hit safely.

Step Three

Divide total bases by official at bats.

Step Four

Round to the third decimal place. For example, .57051 is .571.How do you calculate slugging percentage?
1Step OneAdd up all official at bats. Do not include those at bats that resulted in a walk, sacrifices or hit by pitch.



2Step TwoAdd up total bases. Total bases are how many bases you reached in all the times you hit safely.



3Step ThreeDivide total bases by official at bats.



4Step FourRound to the third decimal place. For example, .57051 is .571.
SLG % = At batts / Total bases



Walks are exluded from the slugging percentage equation.
Ambrose has it exactly right, but since singles data isn't usually available, the alternative version, below, works just as well with a bit more convenience.



SLG == (hits + doubles + 2*triples + 3*homers) / at-bats



conventionally to three decimals.



Edit: I take it back. Ambrose is not distinguishing "singles" from "hits", and failure to do so will give a wrong answer. Unless it's some whifflebat hitter who ONLY gets singles.
