About OPS Calculator

OPS (On-base Plus Slugging) is one of the most popular advanced statistics in baseball, combining a player's ability to get on base (OBP) with their power (SLG). The formula is: OPS = OBP + SLG, where OBP = (H + BB + HBP) / (AB + BB + HBP + SF) and SLG = Total Bases / AB. An OPS above .900 is excellent, .800-.900 is good, .700-.800 is average, and below .700 is below average. This calculator computes all three metrics instantly. All calculations happen in your browser — no data is sent to any server.

Frequently Asked Questions

What is OPS in baseball?

OPS (On-base Plus Slugging) is a sabermetric statistic that combines a player's on-base percentage (OBP) and slugging percentage (SLG). It provides a single number representing a hitter's overall offensive contribution.

What is a good OPS?

In Major League Baseball, OPS above .900 is elite (MVP level), .800-.900 is excellent, .700-.800 is average, and below .700 is below average. The all-time career leaders have OPS above 1.000.

How is OPS calculated?

OPS = OBP + SLG. OBP = (Hits + Walks + Hit By Pitch) / (At Bats + Walks + Hit By Pitch + Sacrifice Flies). SLG = Total Bases / At Bats, where Total Bases = Singles + (2 × Doubles) + (3 × Triples) + (4 × Home Runs).
