Is Slugging Percentage Really a Percentage 

The term Slugging Percentage appears incongruous with its actual meanings. The statistical information is the average base totals a pitcher has at each at-bat, not true percentage statistics.

And usually, it comes in without the decimal point. So if you saw a Slugging Percentage of a player is: 456, it means .456.

The Story Behind Slugging Percentage

From the history of Baseball, the Slugging Percentage is a comparatively new statistic. And have been in use for a long time. While batting average counts a home run the same as a single, slugging percentage takes into account the actual number of bases scored.

In around 1867, Henry Chadwick used to enlist every player’s total base per game. And then, he would calculate the total base average of a player. Because this remarkable man believed that just computing a player’s hits does not show a player’s full effectiveness. And he paved the path to modern slugging percentage.

In modern times, the Slugging Percentage is calculated using total bases per at bat. Later, in 1981, the Slugging Percentage got regular game usage.

The Formula to Calculate Slugging Percentage

As  I said before, the Slugging Percentage is not actually a percentage, it basically shows the average base score. 

The formula of Slugging Percentage = (Total Bases ÷ At Bats) 

Total Bases = Singles + (2 × Double)  + (3 × Triples) + (4 × Home Runs)

Stage 1.

See, if you want to calculate your Slugging Percentage, you need to know the total number of bases you get from the hits. Do not enlist other base advancements.  

Stage 2. 

As most players’ stats do not enlist singles. So, first, you need to calculate how many singles you got. And to get that rule is easy. 

First, sum up all your doubles, triples, and Home Runs/ And then subtract it from the total hits you have. Then you will get all the singles. 

For example, 

Imagine you have scored 100 Home Runs, 76 Triples, and 86 Doubles. Your total hits are 400. 

So, 

400 – (100+ 76+ 86)

= 400 – 262

= 138 

Therefore, you have 138 singles. 

Stage 3. 

Now you must know the total number of bases. 

And the Formula is to calculate total bases,

Total Bases = Singles + (2 × Double)  + (3 × Triples) + (4 × Home Runs)

For example,

Total Bases = Singles + (2 × Double)  + (3 × Triples) + (4 × Home Runs)

= 138 + (2 × 86) + (3 × 76) + (4 × 100) 

= 938

Hence, your total base score is 938. 

Stage 4. 

Now you have to divide the total bases achieved by the total number of at-bats to get your Slugging Percentage.

For Example, 

Slugging Percentage = (Total Bases ÷ At Bats)

= (938 ÷ 1573)

= .5963

Finally, you got your Slugging Percentage which is .5963.

Extra Easy Way for Slugging Percentage Calculation, 

Well, there is another easiest way to calculate Slugging Percentage. 

The Formula is, 

Hits + Double + (2 × Triples) + (3 × Home Runs)

To calculate total bases, you take a batter’s total number of hits and add one additional base for each double, two for each triple, and three for each homer.

Example Calculation, 

Hits + Double + (2 × Triples) + (3 × Home Runs)

= 400 + 86 + ( 2 × 76) + (3 × 100)

=  938

Then you Divide total bases by the number of at-bats to get the slugging percentage, 

Slugging Percentage = (Total Bases ÷ At Bats)

= (938 ÷ 1573)

= .5963

Scored Run and On Base Percentage 

• Here the influence rate is 0.88

Batting Average and Scored Runs 

• 0.80 scoring influence.

Slugging Percentage and Scored Run
