What is a good batting average in baseball?

In Major League Baseball, a .300 batting average is considered excellent, .270–.299 is above average, .250–.269 is average, and below .230 is below average. Standards vary in minor leagues and amateur play.

How is OBP different from batting average?

Batting average only counts hits divided by at-bats. OBP also includes walks (BB) and hit-by-pitches (HBP) in the numerator and denominator, giving credit to batters who reach base without hitting safely.

How is slugging percentage calculated?

SLG = Total Bases ÷ At-Bats, where total bases = singles×1 + doubles×2 + triples×3 + home runs×4. Singles are derived automatically as H − 2B − 3B − HR.

What is OPS and why is it useful?

OPS (On-base Plus Slugging) is simply OBP + SLG. It is widely used because it correlates strongly with run production and is easy to compute. An OPS above .900 is elite; .800 is above average; .700 is average at the MLB level.

Do sacrifice flies count as at-bats?

No. Sacrifice flies (SF) are excluded from at-bats but appear in the denominator of OBP (AB + BB + HBP + SF). Entering SF gives a more accurate OBP, though it is optional in this calculator.

What happens if extra-base hits exceed total hits?

That is not possible in real play — the calculator will show an error if 2B + 3B + HR exceeds total hits, prompting you to correct the values.

Formulas Used

BA = H ÷ AB

OBP = (H + BB + HBP) ÷ (AB + BB + HBP + SF)

SLG = (1B + 2×2B + 3×3B + 4×HR) ÷ AB

OPS = OBP + SLG

Singles (1B) are derived as H − 2B − 3B − HR. OBP and SLG are shown as “N/A” when the optional fields are not filled in.

Summary

Enter hits, at-bats, walks, and extra-base hits to instantly compute batting average, OBP, slugging percentage, and OPS.

How it works

Enter the batter's total hits (H) and at-bats (AB) for the period you want to analyze.
Add walks (BB) and hit-by-pitches (HBP) to enable OBP calculation.
Enter extra-base hit counts (doubles, triples, home runs) to enable slugging percentage.
The calculator applies the official MLB formulas: BA = H/AB, OBP = (H+BB+HBP)/(AB+BB+HBP+SF), SLG = Total Bases/AB.
Sacrifice flies (SF) are optional but improve OBP accuracy when provided.
