What you'll need

How OPS is calculated

OPS = on-base percentage + slugging percentage. It bolts together the two most important things a hitter does — get on base and hit for power — into a single number. This calculator works out OBP, SLG and batting average from your line and adds the two together.

OPS isn't perfect — it treats a point of OBP and a point of SLG as equal when OBP is slightly more valuable — but as a quick, do-the-mental-math snapshot of a hitter, nothing beats it.

What's a good OPS?

In MLB terms: .700 is roughly average, .800 is good, .900+ is excellent, and 1.000+ is star-level. For a young player, use OPS to track improvement over a season rather than as a hard benchmark.

Frequently asked questions

How do you calculate OPS?

Add on-base percentage and slugging percentage together. If OBP is .350 and SLG is .450, OPS is .800.

What is a good OPS?

As a rough guide from the majors: .800 is good, .900 is excellent, and 1.000+ is star-level. For youth players, track the trend rather than a fixed target.

Is OPS better than batting average?

For summarising a hitter, generally yes — OPS captures both getting on base and hitting for power, while batting average only counts hits.
