OPS Calculator

OPS (On-base Plus Slugging) is the sum of on-base percentage and slugging percentage — a key sabermetric that evaluates a batter's ability to get on base and hit for power at the same time.

Enter the on-base percentage (OBP) and slugging percentage (SLG) to instantly calculate OPS by adding them. Generally, an OPS of 0.800 or higher is considered an excellent hitter.

For example, with an OBP of 0.350 and an SLG of 0.450, the OPS is 0.800.

About This Calculator

OPS is on-base percentage plus slugging percentage, a single number that captures both a hitter's ability to avoid outs and their power. It is the most widely used quick summary of offensive value in sabermetrics.

Enter the player's OBP and SLG to add them together, or enter the raw counting stats to compute both and their sum.

OPS simply adds on-base percentage and slugging percentage, so a .350 OBP with a .450 SLG gives .800, close to a league-average season. Because the two components sit on different scales, OPS quietly overweights power: a point of slugging is far more common than a point of OBP, and OPS+ adjusts for the park and the league scoring environment.

Key Formula:OPS = OBP + SLG

Frequently Asked Questions

What is a good OPS?

In MLB, .700 is about average, .800 is good and .900 or higher is excellent — an MVP-calibre season. Anything above 1.000 signals an elite offensive year.

Why is OPS used instead of separate stats?

OPS combines the two most important offensive skills in one easy-to-compare number, which makes ranking hitters simple. Purists prefer wOBA or wRC+ because OPS weighs on-base and slugging equally rather than by their true run value.

Why not just add OBP and SLG as raw numbers?

The ranges differ — OBP averages about .315 and SLG about .400 — so the sum is dominated by slugging. Weighted measures such as wOBA and wRC+ rescale the components by their actual run value.

Is OPS more useful than batting average?

Yes, for almost every purpose. Batting average ignores walks and treats every hit as equal, while OPS captures both the ability to avoid outs and the ability to hit for power.
