Batting Average Calculator
Calculate batting average from hits and at-bats, with conventional three-decimal notation and an additional-digit rate.
Calculate batting average from a recorded hit total and official at-bats. This is a count of successful hits per at-bat, so a single and a home run each contribute one hit. The result includes conventional three-decimal notation and a second value with additional digits.
How to use this tool
- Use official scoring counts from one consistent period.
- Enter whole-number totals; include home runs in total hits.
- Check that the entered counts agree with your scorebook.
- Read the conventional display and inspect the supporting counts.
Formula
AVG = H / AB
H is the number of hits, and AB is official at-bats for the same period. Walks are not added to either count. The tool rejects more hits than at-bats and a zero denominator.
Example
With 30 hits in 100 at-bats, the calculation is 30 ÷ 100 = .300. A separate 1-for-16 line gives 0.0625, displayed as .063 after rounding; the second result preserves more digits.
Reading the result
A rounded rate summarizes the supplied sample. This page does not determine championship eligibility or account for opponent quality. Keep numerator and denominator totals when combining records instead of combining rounded display values.
Frequently asked questions
Do I enter plate appearances or at-bats?
Use official at-bats. Plate appearances also include events that do not count as at-bats, so substituting them changes the statistic.
Should I average two batting averages?
Combine the hits and at-bats, then divide. For example, 1-for-2 and 1-for-8 combine to 2-for-10, or .200; averaging .500 and .125 would give the wrong weight to the small sample.
What does a .300 average mean?
It means 0.300 hits per recorded at-bat in that sample. It is not a promise about the next at-bat, a measure of extra-base power, or a complete description of offensive value.
