Batting average is one of the oldest and most widely recognized statistics in baseball and softball. First recorded in the 1870s, it remains the go-to measure of a hitter's ability to make contact and reach base via hits. Whether you are a coach tracking a roster, a player logging progress through a season, or a parent trying to understand your child's performance at the youth level, a reliable batting average calculator saves you time and eliminates arithmetic errors. Our calculator goes far beyond the simple H/AB formula. It adapts to your competition level — MLB, college, high school, or youth — and adjusts the performance benchmarks accordingly. A .300 batting average in the major leagues signals an elite hitter, but the same number is merely average for a high school player. By selecting the correct level, you get a rating that actually means something in context. In Simple Mode, just enter hits and at-bats. The calculator instantly shows your batting average in the traditional three-decimal format (e.g., .285), assigns a performance rating, displays a visual progress ring scaled to the historic .400 mark, and shows where you stand relative to the Mendoza Line — the .200 threshold below which a batter's job is considered in jeopardy. Advanced Mode unlocks the full offensive stat suite. Enter doubles, triples, and home runs to compute Slugging Percentage (SLG) and Total Bases. Add walks, hit-by-pitch, and sacrifice flies to calculate On-Base Percentage (OBP) — widely considered a more complete measure of offensive value than BA alone. OPS (OBP + SLG) is then computed automatically and displayed with color-coded horizontal comparison bars so you can see the relationship between all three slash-line stats at a glance. Isolated Power (ISO), BABIP, Runs Created, strikeout rate, and walk rate are also computed when the relevant inputs are provided. Game Log Mode is our most powerful differentiating feature. Enter your hits and at-bats game by game — or series by series — and the calculator builds a running batting average chart across your entire log. You can spot hot streaks and slumps, identify turning points in the season, and see whether your recent five-game trend is pointing up or down. Season totals, best-game and worst-game averages, and a line graph visualization are all generated automatically. Softball players are fully supported. Toggle the sport selector to Softball and the benchmark thresholds shift to reflect the higher averages typical of that sport. Youth players at the 12U level regularly hit .400 or above — this calculator will correctly label that as average, not elite, for their age group. The historical context panel reminds users of the all-time benchmarks: Ted Williams' .406 in 1941 (the last time any MLB player hit .400), Ty Cobb's .366 career average, and the modern MLB league average of roughly .240–.260. These anchors help any player or coach calibrate where their numbers sit on the full spectrum of baseball history.
Understanding Batting Average
What Is Batting Average?
Batting average (BA) measures how often a batter gets a hit in an official at-bat. It is expressed as a three-decimal number: a player with 75 hits in 300 at-bats has a batting average of .250. The metric dates to the 1870s and became the primary offensive statistic in professional baseball through most of the 20th century. While modern analytics favor on-base percentage and slugging as more predictive statistics, batting average remains universally understood by fans, coaches, and players at every level. It is particularly intuitive because it directly answers the question: when this player steps up to the plate and actually swings, how often do they get a hit?
How Is Batting Average Calculated?
The formula is BA = H / AB, where H is the number of hits and AB is the number of official at-bats. Not every plate appearance counts as an at-bat. Walks (base on balls), hit-by-pitches, sacrifice flies, sacrifice bunts, and plate appearances that end due to catcher's interference are all excluded from the at-bat denominator. This is why the same statline can show more plate appearances (PA) than at-bats. For advanced stats: Slugging Percentage = Total Bases / AB, where total bases counts singles × 1, doubles × 2, triples × 3, and home runs × 4. OBP = (H + BB + HBP) / (AB + BB + HBP + SF). OPS simply adds OBP and SLG together.
Why Does Batting Average Matter?
Despite the rise of advanced analytics, batting average still carries real-world meaning. Scouts evaluating amateur players often cite BA as a quick signal of bat-to-ball skill. Coaches use it to set lineups: high-average hitters typically slot into the middle of the order or at lead-off. For parents and youth coaches, it is the single number most commonly used to track player development across a season. In fantasy baseball, batting average is one of the five standard rotisserie categories. Even MLB front offices that have moved to OPS+ or wRC+ as primary evaluation tools still track BA as a component of the triple slash line (BA / OBP / SLG) that appears in every box score and broadcaster's lower-third graphic.
Limitations of Batting Average
Batting average treats all hits equally — a bloop single counts the same as a grand-slam home run. This makes it a poor measure of run production or power output. It also ignores walks entirely, meaning a patient hitter who draws many bases on balls will have a lower BA than their overall offensive contribution warrants. BABIP (Batting Average on Balls in Play) can help reveal whether a player's BA is being inflated or deflated by luck: league BABIP typically hovers around .300, so a player with a .380 BABIP may be due for regression regardless of their BA. Finally, sample size matters enormously — a .350 average over 20 at-bats means very little, while the same average over 400 at-bats is highly meaningful.
How to Use the Batting Average Calculator
Select Your Sport and Level
Choose Baseball or Softball from the sport selector, then pick your competition level: MLB/Professional, College (D1), High School, or Youth (12U). This calibrates the performance benchmarks so your rating accurately reflects your level of play — a .300 average means something very different in MLB versus youth baseball.
Enter Hits and At-Bats in Simple Mode
Type your total hits (H) and total at-bats (AB) into the Simple Mode fields, or click one of the Quick Example presets to explore what different batting averages look like. Remember that at-bats exclude walks, hit-by-pitches, and sacrifice flies — only official plate appearances where you swung or struck out count. Your batting average appears instantly as you type.
Unlock Advanced Stats for Full Slash Line
Switch to Advanced Mode and enter your doubles, triples, home runs, walks, HBP, and sacrifice flies to compute your full triple slash line (BA / OBP / SLG) plus OPS, Isolated Power (ISO), BABIP, and Runs Created. The horizontal bar chart shows all four metrics side by side so you can see how your power and on-base skills compare at a glance.
Track Season Progress with Game Log
Switch to Game Log Mode and enter hits and at-bats for each game. Add as many rows as you need with the Add Game button. The calculator builds a running batting average chart across all entered games, showing your cumulative BA trend, best and worst individual game performance, and whether your last five games are trending up or down.

Frequently Asked Questions
What is a good batting average in baseball?
What qualifies as 'good' depends heavily on the level of competition. In MLB, a .300 batting average is considered excellent and earns a player All-Star consideration — only a handful of players reach that mark each season. An average MLB hitter bats around .240–.260. In college baseball (D1), .350 is excellent and .400 puts you among the nation's top hitters. High school players frequently bat .350–.450 in competitive leagues, while youth players at the 12U level commonly hit .400 or above because of the developmental nature of pitching at that age. Always evaluate batting average relative to the competition level, not an absolute number.
What does NOT count as an official at-bat?
Several plate appearances do not count as official at-bats and are excluded from the AB denominator when calculating batting average. These include: base on balls (walks, both intentional and unintentional), hit by pitch (HBP), sacrifice flies (when a fly ball drives in a run), sacrifice bunts (when you bunt to advance a runner and are thrown out), plate appearances that end due to catcher's interference, and plate appearances where an inning ends while you are still batting. This is why a player can have more plate appearances (PA) than at-bats (AB) in their statline, and why OBP is often higher than batting average.
What is the Mendoza Line?
The Mendoza Line refers to a .200 batting average, widely considered the minimum acceptable level of hitting performance for a position player in professional baseball. It is named after Mario Mendoza, a shortstop who played in the major leagues from 1974 to 1983 and whose career batting average hovered around .215. The phrase was popularized by outfielder George Brett, who reportedly said that the first thing he looked at in the morning was the box scores to see who was below the Mendoza Line. Today it is used informally to indicate a player whose offensive production is so low it questions whether their defense justifies keeping them in the lineup.
Why is OBP considered more important than batting average?
On-Base Percentage (OBP) captures something batting average completely ignores: the value of a walk. A player who draws 80 walks per season is reaching base nearly as often as hits — and every time a player reaches base, the team avoids an out. Outs are a finite resource (27 per nine-inning game), so avoiding them has enormous strategic value. Research consistently shows that OBP correlates more strongly with run production and team wins than BA alone. The classic statbook Moneyball popularized this insight by showing how the Oakland A's found undervalued players with high OBP but mediocre batting averages. Most analysts now prefer OPS (OBP + SLG) or wOBA as offensive summary statistics.
What is BABIP and how should I use it?
BABIP stands for Batting Average on Balls in Play. The formula is (H − HR) / (AB − K − HR + SF). It measures a batter's average on all balls put in play — excluding home runs and strikeouts, which are not affected by defense. The major-league average BABIP has historically been around .295–.305. When a player's BABIP is significantly above that range (say, .380), it may indicate they have been hitting with an unsustainable amount of luck — well-placed grounders, dying quails — and their batting average may regress downward. A very low BABIP (.240) may signal bad luck or that fielders are positioned perfectly against them, suggesting their average may improve. BABIP is best used alongside other stats, not in isolation.
How do I track my batting average over a season using Game Log Mode?
Switch to Game Log Mode using the tabs at the top of the calculator. Enter your hits and at-bats for each game — one row per game. Use the Add Game button to add as many rows as you need, and the Remove button to delete any incorrect entries. As you fill in each row, the calculator automatically computes your cumulative (running) batting average after each game and plots it as a line graph. You can see your best-game and worst-game performances, your recent five-game trend, and your full-season totals. When your log is complete, use the Export CSV button to download the data for your coach's stat sheets or personal records.
