Hitting Stats Calculator

Batting average, OBP, slugging and OPS.

Enter one stat line and get all four rate stats at once, plus total bases and a rating. Doubles, triples and home runs are treated as part of the hit total the way a scorebook records them, so slugging comes out right.

AVG / OBP / SLG / OPS Total bases Rated vs benchmarks

Extra-base hits are already hits

A double is one hit worth two bases, not a hit plus a double. Enter 28 hits including 6 doubles, and singles work out to 22. Adding them on top is the fastest way to a wrong slugging percentage.

What counts as good

StatBenchmark
Batting average.300 is excellent, .250 is around average
On-base percentage.400 is excellent, .320 is around average
Slugging percentage.500 is excellent, .400 is around average
OPS.900 is excellent, .720 is around average

On the pitching side, the ERA and WHIP calculator does the same job.

How do you calculate batting average?

Batting average is hits divided by at bats. A player with 28 hits in 100 at bats is hitting .280. Walks, hit by pitches, and sacrifices are not at bats, so they neither help nor hurt average.

How do you calculate OBP?

On-base percentage is (hits + walks + hit by pitch) divided by (at bats + walks + hit by pitch + sacrifice flies). Note that sacrifice flies are in the denominator but sacrifice bunts are not, which is the detail most calculators get wrong.

How do you calculate slugging percentage?

Slugging is total bases divided by at bats. Total bases counts a single as 1, a double as 2, a triple as 3, and a home run as 4. Because doubles, triples, and homers are already part of the hit total, singles are hits minus those three.

What is OPS and what is a good one?

OPS is on-base percentage plus slugging percentage. Roughly .720 is average at a competitive level, .800 is solid, .900 is excellent, and over 1.000 is elite. It is popular because it captures getting on base and hitting for power in one number.

Why can OPS be over 1.000 when the parts look like percentages?

Because slugging is not capped at 1. A home run is four total bases in one at bat, so slugging can exceed 1.000 on its own. Adding it to on-base percentage means OPS above 1.000 is uncommon but entirely possible.

Do walks count toward batting average?

No. A walk is not an at bat, so it does not appear in batting average at all. That is exactly why on-base percentage exists — a player who walks often can have a modest average and still be one of the hardest outs in the lineup.
