A batting average shows how often a baseball or softball player gets a hit or how many runs a cricket batter scores per dismissal. A Batting Average Calculator makes the calculation simple by using the correct statistics for the sport you select. In baseball and softball, divide hits by official at-bats. In cricket, divide total runs by the number of times the batter was dismissed. This guide explains both formulas, shows worked examples, and explains how to read and compare batting averages.
Key Takeaways
- Baseball and softball: Divide total hits by official at-bats to calculate batting average.
- Cricket: Divide total runs scored by the number of dismissals.
- Baseball batting averages are usually displayed as decimals to three places, such as .300.
- Walks and hit-by-pitches do not count as official at-bats in baseball.
- Batting average measures hitting results, but it does not show every part of a player’s offensive contribution.
What Does a Batting Average Calculator Calculate?
A Batting Average Calculator calculates a player’s batting average from the statistics recorded for their sport. For baseball and softball, the inputs are hits and official at-bats. For cricket, the inputs are runs scored and dismissals.
The calculator divides the relevant total by the correct number of opportunities or dismissals. The result helps players, coaches, scorekeepers, and fans track batting performance across a game, season, or career.
The calculation differs by sport, so you should select the correct method before entering your numbers. Major League Baseball (MLB) defines baseball batting average as hits divided by at-bats. The Marylebone Cricket Club (MCC) maintains the Laws of Cricket, which govern cricket scoring and dismissals.
What Is the Batting Average Formula?
The batting average formula depends on whether you are calculating baseball or cricket statistics.
Baseball and Softball Batting Average Formula
Where:
- BA = batting average.
- H = total hits.
- AB = total official at-bats.
Divide the player’s total hits by their official at-bats. Singles, doubles, triples, and home runs all count as hits.
For example, a player with 87 hits in 300 official at-bats has a batting average of .290.
MLB uses this formula for its official batting average statistic. Walks and hit-by-pitches do not count as at-bats. Sacrifice bunts, sacrifice flies, and certain other outcomes are excluded under the official scoring rules.
Cricket Batting Average Formula
Where:
- Total Runs = the runs credited to the batter.
- Dismissals = the number of times the batter has been out.
For example, a cricket batter who scores 240 runs across 6 dismissals has a batting average of 40.
Cricket batting average is measured in runs per dismissal. A batter who remains not out in an innings has not been dismissed in that innings, so that innings does not increase the dismissal count.
Do not use the baseball formula for cricket. Baseball uses hits and official at-bats, whereas cricket uses runs and dismissals.
How to Use the Batting Average Calculator
Follow these steps to calculate batting average correctly.
- Select the sport. Choose baseball or softball for a hits-and-at-bats calculation, or cricket for a runs-and-dismissals calculation if the tool supports both.
- Enter the first statistic. For baseball or softball, enter total hits. For cricket, enter total runs.
- Enter the denominator. For baseball or softball, enter official at-bats. For cricket, enter the number of dismissals.
- Calculate the average. Run the calculation to obtain the batting average.
- Check the result. Confirm that you entered the correct statistics and used the right sport-specific formula.
For season or career statistics, use totals from the full period being measured. Do not average several individual batting averages together unless you are deliberately calculating a simple mean of those averages. The correct season or career batting average comes from the combined totals.
How to Calculate Batting Average With Examples
These examples show how to calculate batting average for baseball and cricket.
Example 1: Baseball Batting Average
Suppose a baseball player records 105 hits in 350 official at-bats.
Formula:
Substitution:
Result:
The player’s batting average is .300, commonly read as “three hundred.” This means the player recorded a hit in 30% of their official at-bats.
Example 2: Baseball Batting Average for One Game
A player gets 2 hits in 5 official at-bats during a game.
The player’s batting average for those at-bats is .400.
This result describes the five at-bats in that game. It does not mean the player has a .400 season average.
Example 3: Cricket Batting Average
Suppose a cricket batter scores 360 runs and has been dismissed 9 times.
Formula:
Substitution:
Result:
The batter’s average is 40 runs per dismissal.
What Counts as an Official At-Bat in Baseball?
An official at-bat is a statistical category used in baseball to calculate batting average. It does not include every completed trip to the plate.
According to MLB’s official glossary, a batter records an at-bat for outcomes such as a hit, a fielder’s choice, reaching base on an error, or being put out on a non-sacrifice play.
Common outcomes that do not count as at-bats include:
- Walks.
- Hit-by-pitches.
- Sacrifice bunts.
- Sacrifice flies.
- Catcher’s interference.
The official scoring decision determines whether an event counts as an at-bat. For example, a player who receives a walk has completed a plate appearance, but the walk does not add to their at-bat total.
Use the official at-bat total from the scorebook or statistics record. Counting every plate appearance as an at-bat can produce an incorrect batting average.
What Is a Good Batting Average in Baseball?
A good batting average depends on the competition level, the season, and the player’s role. In Major League Baseball, a .300 average has traditionally been viewed as an excellent mark, but league averages vary by season.
MLB notes that the league-wide batting average has typically been around .250 in recent years. This gives readers a broad reference point, not a fixed standard for every league or age group.
Use these points when interpreting a baseball batting average:
- .300: A strong benchmark for a baseball hitter.
- Around .250: A useful general reference for recent MLB league-wide performance.
- Below .200: A low batting average, though it does not tell the full story of a player’s value.
These are broad reference points, not official ratings. Youth leagues, amateur competitions, professional leagues, and softball can have different performance patterns. Compare players within a similar competition and account for the number of at-bats.
What Are the Limitations of Batting Average?
Batting average measures how often a baseball batter gets a hit in official at-bats. It does not measure every part of offensive performance.
For example, a batter who draws many walks may reach base often without increasing their batting average. A batter who hits doubles and home runs may contribute more total bases than a player who records the same number of singles, even if both players have identical batting averages.
Other statistics provide additional context:
- On-base percentage (OBP): Measures how often a player reaches base, including qualifying walks and hit-by-pitches.
- Slugging percentage (SLG): Measures total bases per at-bat and gives more weight to extra-base hits.
- On-base plus slugging (OPS): Adds on-base percentage and slugging percentage to provide a broader view of offensive production.
MLB explains the distinctions between these statistics in its official glossary. Batting average remains useful for tracking hits, but it should not be treated as a complete measure of a player’s offensive value.

Frequently Asked Questions
Can batting average be calculated when a player has zero at-bats?
No. Division by zero is undefined, so a baseball batting average cannot be calculated from zero official at-bats. Statistics systems may display .000 or another placeholder for an unqualified player, depending on their conventions.
Why is a baseball batting average written as .300 instead of 30%?
Baseball convention displays batting average as a decimal, usually to three places. A .300 average represents a hit in 30% of official at-bats, but the standard display is .300.
How do not-out innings affect a cricket batting average?
A not-out innings does not add a dismissal to the denominator. The batter’s average is calculated from total runs divided by dismissals, so not-out innings can increase the average relative to the same runs with more dismissals.
