Slugging Percentage Calculator

The slugging percentage calculator is a tool for baseball enthusiasts to evaluate how good a player is at making powerful hits. It does this by considering different types of base hits (singles, doubles, triples, and home runs) and analyzes their impact compared to the total number of times the player has been at-bat.

What is slugging percentage in baseball?

Slugging percentage (SLG) is a baseball statistic that represents a hitter's power by considering the total number of bases they record per at-bat.

The name slugging percentage might sound like a percentage, but it's actually an average of bases reached per bat. A higher slugging percentage usually indicates a player is skilled at making strong hits, which contributes to their team scoring more runs when it comes to offense.

The slugging percentage calculator is different from the on-base percentage calculator because it only focuses on hits in its calculation, instead of walks and hit-by-pitches.

Hits valuation chart:

Each type of hit is assigned a value:

• Single: 1 base
• Double: 2 bases
• Triple: 3 bases
• Home run: 4 bases

Slugging percentage formula?

The slugging percentage is calculated using the following formula:

SLG = (1B + 2Bx2 + 3Bx3 + HRx4) / AB

Where,

• SLG – Slugging percentage
• 1B – Number of singles (1 base hit)
• 2B – Number of doubles (2 base hits)
• 3B – Number of triples (3 base hits)
• HR – Number of home runs (4 base hits)
• AB – Total number of at-bats, representing a player's plate appearances

How is slugging percentage calculated?

For quick and accurate calculations, it's recommended to use the slugging percentage calculator provided by Calculatored. However, if you intend to calculate it manually, follow the example given below:

Example:

Let’s imagine a baseball player named Sarah Jones who finished a game with the following statistics.

• Singles (1B): 40
• Doubles (2B): 20
• Triples (3B): 5
• Home Runs (HR): 10
• At-Bats (AB): 150

Step 1: Calculate total bases using the formula:

• Total bases = (1B + 2Bx2 + 3Bx3 + HRx4)
• Total bases = (40 x 1) + (20 x 2) + (5 x 3) + (10 x 4)
• Total bases = 40 + 40 + 15 + 40
• Total bases = 135

Step 2: Divide total bases by at-bats:

• SLG = Total bases / AB
• SLG = 135 bases / 150 at-bats

Step 3: Express the result as a decimal:

• SLG = 0.900 (rounded to three decimal places)

Typically, the "0" before the decimal point is omitted. Therefore, the final result of the Sarah Jones’ slugging percentage calculation would be:

• SLG = .900

This means she earns an average of 0.9 bases for every at-bat, indicating a very strong offensive performance considering the average MLB career slugging percentage is around .435.
