What Is Batting Average in Baseball?
Batting average, commonly abbreviated AVG or BA, measures the proportion of official at-bats that result in hits.
It is calculated by dividing a player’s hits by their at-bats.
Batting Average Formula
For example, a player with 30 hits in 100 at-bats has a batting average of .300.
A .300 batting average means the player recorded a hit in 30% of official at-bats.
Batting average is traditionally displayed as a three-digit decimal, such as .250, .275, or .300.
Batting Average Calculation Example
Example: Suppose a baseball player has the following hitting statistics over several games.
Example Baseball Statistics
- At-Bats: 100
- Hits: 30
- Doubles: 6
- Triples: 1
- Home Runs: 4
- Walks: 10
- Hit by Pitch: 1
- Sacrifice Flies: 2
Step 1: Calculate Batting Average
Divide hits by official at-bats.
The player has a .300 batting average.
Step 2: Calculate Singles
The total hit count includes singles, doubles, triples, and home runs.
Subtract extra-base hits from total hits to determine the number of singles.
Step 3: Calculate Total Bases
Each single earns one total base, each double two, each triple three, and each home run four.
Using our example:
Step 4: Calculate Slugging Percentage
Divide total bases by official at-bats.
Step 5: Calculate On-Base Percentage
On-base percentage includes hits, walks, and hit by pitch.
The denominator includes at-bats, walks, hit by pitch, and sacrifice flies.
First calculate the numerator.
Next calculate the denominator.
Step 6: Calculate OPS
OPS stands for On-Base Plus Slugging.
Add the player’s on-base percentage and slugging percentage.
Use unrounded values when calculating OPS, then round the final result for display.
Batting Calculation Example Summary
| Statistic | Illustrative Result |
|---|---|
| At-Bats | 100 |
| Hits | 30 |
| Singles | 19 |
| Doubles | 6 |
| Triples | 1 |
| Home Runs | 4 |
| Total Bases | 50 |
| Batting Average | .300 |
| On-Base Percentage | .363 |
| Slugging Percentage | .500 |
| OPS | .863 |
This example shows how the same hitting statistics can be used to evaluate contact, on-base ability, and extra-base hitting production.
Batting Average Chart – Hits per 100 At-Bats
The following table shows the batting averages produced by different hit totals over 100 official at-bats.
| Hits | At-Bats | Batting Average |
|---|---|---|
| 10 | 100 | .100 |
| 15 | 100 | .150 |
| 20 | 100 | .200 |
| 25 | 100 | .250 |
| 27 | 100 | .270 |
| 30 | 100 | .300 |
| 33 | 100 | .330 |
| 35 | 100 | .350 |
| 40 | 100 | .400 |
These are mathematical examples rather than current professional baseball averages.
What Is On-Base Percentage (OBP)?
On-base percentage measures how often a batter reaches base through hits, walks, or hit by pitch, relative to the opportunities counted in the OBP formula.
Unlike batting average, OBP gives credit for reaching base through walks and hit by pitch.
On-Base Percentage Formula
A player can have a higher OBP than batting average because walks and hit by pitch provide additional opportunities to reach base.
Batting Average vs. On-Base Percentage
Consider two players who each record 30 hits in 100 at-bats.
Player A draws five walks, while Player B draws 20 walks.
For this simplified comparison, assume no hit by pitch or sacrifice flies.
| Statistic | Player A | Player B |
|---|---|---|
| At-Bats | 100 | 100 |
| Hits | 30 | 30 |
| Walks | 5 | 20 |
| AVG | .300 | .300 |
| OBP | .333 | .417 |
Both players have the same batting average, but Player B has a higher on-base percentage because of the additional walks.
What Is Slugging Percentage (SLG)?
Slugging percentage measures total bases gained through hits per official at-bat.
Unlike batting average, slugging percentage gives greater weight to extra-base hits.
A double counts for two total bases, a triple for three, and a home run for four.
Slugging Percentage Formula
For example, 50 total bases over 100 at-bats produce a slugging percentage of .500.
Despite its name, slugging percentage is not a percentage of successful at-bats and may exceed 1.000.
Baseball Total Bases Chart
| Hit Type | Total Bases |
|---|---|
| Single | 1 |
| Double | 2 |
| Triple | 3 |
| Home Run | 4 |
Only bases earned from the batter’s hits contribute to total bases for slugging percentage.
Stolen bases and advancement on another player’s hit do not add to a batter’s total bases.
What Is OPS in Baseball?
OPS stands for On-Base Plus Slugging.
It combines a player’s ability to reach base with their extra-base hitting production.
For example, a player with an OBP of .350 and a SLG of .450 has an OPS of .800.
OPS is useful for comparing offensive production, but it is not a complete measure of player value.
It does not independently adjust for ballpark effects, league environment, baserunning, or defensive ability.
Batting Average vs. Slugging Percentage
Example: Two players each get 10 hits in 40 at-bats.
Player A hits 10 singles.
Player B records six singles and four doubles.
Player A: Singles Only
Player B: Extra-Base Hits
The two players have identical batting averages, but Player B has a higher slugging percentage because of the doubles.
What Is the Difference Between At-Bats and Plate Appearances?
An at-bat is a specific official scoring category. Not every completed plate appearance counts as an at-bat.
For example, walks, hit by pitch, sacrifice flies, and sacrifice bunts generally do not count as official at-bats.
Those events may still count toward a player’s plate appearance total.
This distinction matters because batting average uses at-bats, while OBP uses a different denominator.
Do Walks Count Toward Batting Average?
No. A walk does not count as a hit or an official at-bat in the batting average calculation.
Walks are included in the on-base percentage formula.
This allows a player to maintain the same batting average while improving OBP through additional walks.
Does Hit by Pitch Affect Batting Average?
Being hit by a pitch does not produce a hit or an official at-bat.
However, it can increase the player’s on-base percentage because it is included in OBP.
Do Sacrifice Flies Count as At-Bats?
A correctly scored sacrifice fly generally does not count as an official at-bat.
However, sacrifice flies are included in the denominator of the standard OBP formula.
That is why the MyCruncher calculator includes a separate Sacrifice Flies field.
How to Calculate Batting Average for a Season
To calculate a season batting average, add all official hits and at-bats from the season.
Then divide the combined hits by the combined at-bats.
For example, a player has 150 hits in 500 at-bats.
Do not simply average the batting averages from separate games when their at-bat totals differ.
Why Does Sample Size Matter in Baseball?
A player who records three hits in three at-bats has a batting average of 1.000.
That is an excellent individual game result, but a very small sample.
A player’s batting average can change substantially after just a few additional at-bats.
Comparing players over longer periods can provide more context than comparing only one game.
How to Compare Baseball Hitters
Batting average, OBP, SLG, and OPS each describe different parts of offensive performance.
- Batting Average: How often the player records hits per official at-bat.
- On-Base Percentage: How often the player reaches base through events included in the OBP formula.
- Slugging Percentage: The average total bases earned per official at-bat.
- OPS: A combined measure of on-base ability and slugging production.
Using multiple statistics together offers more context than relying on batting average alone.
Common Batting Average Calculation Mistakes
- Using plate appearances instead of at-bats. Batting average requires official at-bats.
- Counting walks as hits. Walks affect OBP, not AVG.
- Counting doubles twice as hits. A double is one hit but two total bases.
- Forgetting that home runs are already hits. Do not add home runs to the hit total a second time.
- Using stolen bases in SLG. Slugging uses total bases from hits, not baserunning.
- Ignoring sacrifice flies in OBP. SF belongs in the standard OBP denominator.
- Rounding too early. Use full-precision OBP and SLG before calculating OPS.
- Dividing by zero. An average with zero at-bats is mathematically undefined.
- Averaging game averages. Combine hits and at-bats instead of averaging individual game rates.
