Slugging Percentage and OPS Calculator
Enter a batter's at bats and the breakdown of hits to compute total bases and slugging percentage. Add an on-base percentage and the tool also returns OPS.
How to calculate slugging percentage
- Enter at bats and the number of singles, doubles, triples and home runs.
- Read the total bases and slugging percentage.
- Optionally enter an on-base percentage to also see OPS.
Examples
500 at bats with 100 1B, 30 2B, 5 3B, 25 HR
atBats 500, singles 100, doubles 30, triples 5, homeRuns 25
Total bases 275, slugging .550
Frequently asked questions
How is slugging percentage calculated?
Slugging percentage is total bases divided by at bats. Total bases weight each hit by its value: singles count 1, doubles 2, triples 3 and home runs 4. So total bases equals 1B + 2 times 2B + 3 times 3B + 4 times HR.
What is OPS?
OPS is on-base plus slugging, the sum of on-base percentage and slugging percentage. It is a quick single number that rewards both reaching base and hitting for power. Enter an on-base percentage and this tool adds it to slugging to give OPS.
How is slugging different from batting average?
Batting average treats every hit the same, while slugging percentage rewards extra-base hits. A player with many home runs can have a slugging percentage well above their batting average.
What is a good slugging percentage?
In modern Major League Baseball a slugging percentage around .400 is roughly average, .500 is very good and .550 or higher is elite power production.
Can slugging percentage be greater than 1.000?
Yes. Because a single at bat can produce up to four total bases, slugging percentage can exceed 1.000. The theoretical maximum is 4.000, a home run in every at bat.
