Batting Average Calculator
Our baseball calculator computes batting average instantly. Get accurate stats with historical comparisons and benchmarks.
Formula
BA = Hits / At-Bats | OBP = (H+BB+HBP) / (AB+BB+HBP+SF) | SLG = Total Bases / AB
Batting average divides total hits by at-bats. On-base percentage accounts for walks and hit-by-pitches. Slugging percentage weights extra-base hits by their base value. OPS combines OBP and SLG for a comprehensive offensive metric.
Worked Examples
Example 1: Season Performance Evaluation
Problem: A player has 162 hits in 540 at-bats, with 25 doubles, 5 triples, 30 home runs, and 102 singles. They also had 70 walks, 5 HBP, and 6 sacrifice flies. Calculate their batting statistics.
Solution: BA = 162 / 540 = .300\nTotal Bases = 102(1) + 25(2) + 5(3) + 30(4) = 102 + 50 + 15 + 120 = 287\nSLG = 287 / 540 = .531\nOBP = (162 + 70 + 5) / (540 + 70 + 5 + 6) = 237 / 621 = .382\nOPS = .382 + .531 = .913
Result: BA = .300 | OBP = .382 | SLG = .531 | OPS = .913 (Elite)
Example 2: Comparing Two Hitters
Problem: Player A has 135 hits in 500 at-bats (all singles). Player B has 120 hits in 500 at-bats (60 singles, 25 doubles, 5 triples, 30 home runs). Who is the better offensive contributor?
Solution: Player A: BA = .270, TB = 135, SLG = .270\nPlayer B: BA = .240, TB = 60 + 50 + 15 + 120 = 245, SLG = .490\nPlayer A OPS ≈ .270 + OBP | Player B OPS ≈ .490 + OBP\nDespite lower BA, Player B produces far more total bases.
Result: Player B (SLG .490) is the stronger offensive contributor despite a lower BA (.240 vs .270)
Frequently Asked Questions
What is batting average and how is it calculated?
Batting average (BA or AVG) is one of the oldest and most widely recognized statistics in baseball. It is calculated by dividing the total number of base hits by the total number of official at-bats. The formula is simply BA = Hits / At-Bats. An at-bat does not include walks, hit-by-pitches, sacrifices, or obstruction calls. A batting average of .300 or higher is considered excellent in Major League Baseball, meaning the batter gets a hit roughly 3 out of every 10 at-bats. The statistic has been used since the 1870s and remains a fundamental measure of a hitter's ability to make contact and reach base safely via a hit.
What is considered a good batting average in MLB?
In Major League Baseball, a batting average of .300 or above is considered excellent and typically places a player among the league leaders. An average between .270 and .299 is above average and indicates a solid, productive hitter. The league-wide average usually hovers around .250 to .260 in modern baseball. An average between .220 and .249 is below average but still acceptable for players who contribute in other ways such as power hitting or exceptional defense. Below .200 is often referred to as the 'Mendoza Line,' named after Mario Mendoza, and typically indicates a struggling hitter who may face roster cuts unless they provide outstanding value in other areas of the game.
What is the difference between batting average and on-base percentage?
While batting average only counts hits divided by at-bats, on-base percentage (OBP) measures how frequently a batter reaches base by any means. The OBP formula is (Hits + Walks + Hit-by-Pitch) / (At-Bats + Walks + Hit-by-Pitch + Sacrifice Flies). This makes OBP a more comprehensive statistic because it rewards batters who draw walks and get hit by pitches, both of which contribute to not making outs. Many modern analysts consider OBP more valuable than batting average because it better correlates with scoring runs. A player with a .250 batting average but a .380 OBP is often more valuable than one hitting .290 with a .310 OBP, because getting on base by any method helps the team score.
How does slugging percentage differ from batting average?
Slugging percentage (SLG) measures the total number of bases a player earns per at-bat, giving more weight to extra-base hits. While batting average treats all hits equally, slugging percentage assigns values: a single equals 1, a double equals 2, a triple equals 3, and a home run equals 4. The formula is Total Bases / At-Bats. For example, a player with 2 singles and 1 home run in 10 at-bats has a batting average of .300 but a slugging percentage of .600 (6 total bases / 10 at-bats). This distinction is critical because slugging percentage better captures a hitter's power contribution. A power hitter with a .250 average but .500 slugging percentage is producing more offense per at-bat than a contact hitter batting .300 with .350 slugging.
