What Is an OPS Calculator?

OPS (On-base Plus Slugging) is one of the most widely used baseball stats for measuring overall offensive value in a single number. It's simply on-base percentage added to slugging percentage, combining a hitter's ability to reach base with their power once they get a hit.

This calculator takes a full batting line — at-bats, hits, extra-base hits, walks, hit-by-pitch and sacrifice flies — and computes OBP, SLG and OPS using the standard formulas used across MLB and sabermetric sites.

How to Read Your Results

OPS (OBP + SLG)

The headline number. League-average OPS in modern MLB is roughly .720-.750. An OPS above .800 is a good offensive season, and .900+ is typically All-Star level production.

On-Base Percentage

The share of plate appearances (at-bats, walks, hit-by-pitches and sacrifice flies) that end with the batter reaching base safely via a hit, walk or HBP.

Slugging Percentage

Total bases divided by at-bats — a measure of raw power that rewards doubles, triples and home runs more than singles.

Total Bases

The sum of bases earned across all hits, used to calculate slugging percentage.

Real-World Example

A hitter records 120 hits (24 doubles, 3 triples, 15 home runs) in 400 at-bats, with 50 walks, 5 hit-by-pitches and 5 sacrifice flies.

StatValue
Total bases120 + 24 + 6 + 45 = 195
Slugging percentage195 ÷ 400 = .488
On-base percentage(120+50+5) ÷ (400+50+5+5) = .380
OPS.380 + .488 = .868

An .868 OPS combines above-average on-base skills with strong power, placing this hitter well above the league-average line of roughly .730.

Tips for Using This Calculator

  • Sacrifice bunts don't count toward the OBP denominator — only sacrifice flies do.
  • OPS is not park- or league-adjusted. A hitter's raw OPS can look inflated or deflated depending on their home ballpark.
  • Compare against league average for the season rather than a fixed number, since league-wide offense shifts year to year.
  • Use OPS+ or wOBA for deeper analysis if you need park- and league-adjusted comparisons.
