Calculate batting average for baseball or cricket. The baseball mode computes BA from at-bats and hits, with optional expansion to the full sabermetric slash line — on-base percentage, slugging, and OPS. The cricket mode computes runs per dismissal the way ICC does, correctly handling not-outs.
Batting average is the most-cited individual statistic in bat-and-ball sports. In baseball it measures the rate at which a hitter gets hits per at-bat — a .300 average means 3 hits per 10 at-bats. In cricket it measures average runs per dismissal across a player's innings. The two stats share a name but compute differently. Baseball batting averages run between .200 and .400 in elite play and are written without a leading zero. Cricket averages run from the teens to the 50s for great Test batsmen and are written to two decimals. The Batting Average Calculator handles both conventions and, for baseball, extends into the full sabermetric slash line of on-base percentage, slugging, and OPS.
The calculator runs entirely in your browser. No data leaves your device, and the math is the same exact formula used by MLB and ICC official scorers.
Enter at-bats and hits. The calculator divides hits by at-bats, rounds to three decimals, and drops the leading zero — so 50 hits in 200 at-bats displays as .250. Validation prevents impossible inputs like more hits than at-bats.
Toggle on the OBP/SLG/OPS panel to add walks, hit-by-pitch, sacrifice flies, doubles, triples, and home runs. The calculator computes OBP as (H+BB+HBP)/(AB+BB+HBP+SF), SLG as total bases / AB, and OPS as their sum. Each metric only appears if you've entered the needed inputs.
Enter total runs, innings batted, and not-outs. The calculator computes dismissals = innings − notOuts and then average = runs / dismissals. If every innings was a not-out, the average is mathematically undefined and the calculator says so rather than printing infinity.
Five formulas total — one for cricket, four for baseball's slash line. All shown exactly as MLB and ICC scorers use them.
The numerator is hits — singles, doubles, triples, and home runs. The denominator is at-bats, which excludes walks, hit-by-pitch, sacrifice bunts, sacrifice flies, and catcher interference. Result is displayed as a three-decimal value without leading zero, like .275.
150 hits / 550 at-bats = 0.2727 → displays as .273
Hits, walks, and hit-by-pitches go in the numerator. The denominator is plate appearances minus sacrifice bunts (SH). Sacrifice flies (SF) count in the denominator because they're considered a productive out the batter could have avoided. This has been the official MLB OBP formula since 1984.
(150 + 80 + 5) / (550 + 80 + 5 + 8) = 235 / 643 = .366
Slugging weights extra-base hits by the bases they earn. The numerator (total bases) treats a single as 1, a double as 2, a triple as 3, and a home run as 4. The denominator is the same at-bats used for batting average. Maximum possible value is 4.000 (every at-bat a home run); .500 is excellent.
Singles 100 + 2×30 doubles + 3×5 triples + 4×40 HR = 335 total bases. 335 / 550 = .609
A composite metric that adds OBP and SLG. Despite mixing two different denominators (a known flaw), OPS correlates extremely well with team runs scored — better than either stat alone. .800 is good, .900 is excellent, 1.000+ is MVP territory. Babe Ruth's career OPS was 1.164, the highest ever for a player with 5000+ plate appearances.
OBP .366 + SLG .609 = OPS .975
Cricket divides total runs by dismissals, not innings. A 'not-out' is an innings that ended without the batter being dismissed — the team total was reached, declared, or the match ended first. The convention exists because the batter could have scored more had the innings continued. The result is displayed to two decimals.
6996 runs / (80 innings − 10 not-outs) = 6996 / 70 = 99.94 (Bradman's actual career average)
How a given batting average maps to performance level, with rough equivalents in hit-rate terms.
| Batting average | Hits per 100 AB | Level |
|---|---|---|
| .400 | 40 | Historic — last achieved 1941 by Ted Williams |
| .350 | 35 | MVP-level season, Hall of Fame trajectory |
| .320 | 32 | Batting title contender most years |
| .300 | 30 | Excellent — traditional 'good hitter' threshold |
| .275 | 27.5 | Above-average MLB regular |
| .250 | 25 | Roughly league average in modern MLB |
| .220 | 22 | Below average; bench/utility level |
| .180 | 18 | 'Mendoza Line' — below this is usually a demotion |
What each tier looks like in baseball and cricket. The thresholds are widely accepted by historians and analysts, though not officially codified.
| Tier | Baseball BA | Cricket avg. | Examples |
|---|---|---|---|
| All-time great | .350+ | 55+ Test | Cobb .366 | Bradman 99.94 |
| Hall of Fame | .300–.349 | 45–54 | Wagner .329 | Tendulkar 53.78 |
| All-Star regular | .280–.299 | 40–44 | Brett .305 | Kohli 49.0 |
| Solid starter | .260–.279 | 35–39 | League average for batting title contenders |
| MLB / Test regular | .240–.259 | 30–34 | Roughly the qualifying-player middle 50% |
| Below average | .220–.239 | 25–29 | Defense-first players, lower-order batters |
| Replacement level | .200–.219 | 20–24 | Borderline major-league hitters |
| Below Mendoza | < .200 | < 20 | Usually demoted or specialist roles |
Both sports call their flagship stat 'batting average,' but the formulas, denominators, and typical values diverge sharply. Here's the side-by-side.
Rate stat — fraction of at-bats that produce a hit. Bounded between .000 and 1.000 in theory, but elite performance tops out around .400 because of pitcher quality and defensive positioning. Walks don't help your BA; only hits do.
Counting stat as a ratio — runs accumulated per dismissal. Innings can produce 50, 100, or 200+ runs each, so averages reach the 40s and 50s for elite Test batsmen. Not-outs (innings ending without dismissal) shrink the denominator and raise the average.
| Aspect | Baseball | Cricket |
|---|---|---|
| Maximum possible | 1.000 | Unbounded |
| Decimal places | 3 (no leading zero) | 2 |
| Elite level | .320+ | 50+ Test |
| Average regular | .250 | 30–35 Test |
| What boosts it | Hits only | Runs + not-outs |
| Walk-equivalent counted? | No (BA), Yes (OBP) | N/A — no walks |
Two players with identical .250 batting averages can have wildly different OBPs depending on plate discipline. OBP is generally a stronger predictor of runs scored.
Ignores walks entirely. A free-swinger with .280 BA but only 20 walks all year has the same BA as a patient hitter with 80 walks, but they create runs at very different rates.
Credits every way of reaching base safely. A .250 hitter who walks 80 times in 600 plate appearances has a roughly .340 OBP — significantly above league average and a real run-producing asset.
| Player | BA | Walks | OBP | Better stat |
|---|---|---|---|---|
| Free swinger | .280 | 20 | .302 | BA looks better |
| Patient hitter | .250 | 80 | .343 | OBP wins by far |
| Difference | +.030 BA | −60 BB | −.041 OBP | OBP catches what BA misses |
Two players can have the same batting average but vastly different power output. Slugging captures what BA leaves out: the bases-per-hit dimension.
Lots of singles, few extra-base hits. A .300 batting average is impressive, but if 90% of those hits are singles, the slugging value is around .400 — solid but not elite.
Same .300 BA, but doubles and home runs make up 40% of the hit total. Slugging climbs to .550–.650, OPS into the .900s — MVP territory.
| Stat | Contact hitter | Power hitter |
|---|---|---|
| BA | .300 | .300 |
| Singles per 150 hits | 130 | 85 |
| Doubles | 15 | 35 |
| Home runs | 5 | 30 |
| SLG | ≈.400 | ≈.580 |
| OPS (with .350 OBP) | .750 | .930 |
Real lines from historical players, computed step by step.
Cobb had 248 hits in 591 at-bats during his 1911 American League MVP season. BA = 248 / 591 = 0.4196, which rounds to .420 in conventional display. He led the league in hits, runs, RBIs, stolen bases, and batting average that year, winning the MVP unanimously.
Judge's 2024 line: 180 hits in 559 at-bats (.322 BA), with 133 walks, 9 HBP, and 7 sacrifice flies. OBP = (180+133+9) / (559+133+9+7) = 322 / 708 = .455. With 36 doubles, 1 triple, and 58 home runs, total bases = 85 singles + 72 + 3 + 232 = 392. SLG = 392 / 559 = .701. OPS = .455 + .701 = 1.156 — his MVP season.
Sachin Tendulkar finished his Test career with 15,921 runs in 329 innings, with 33 not-outs. Dismissals = 329 − 33 = 296. Average = 15921 / 296 = 53.78. Across all formats he holds 100 international centuries — a record that remains untouched and likely will for decades.
Batting average is volatile in small samples. A player going 5-for-15 has a .333 BA, but that means nothing — the actual confidence interval at 15 at-bats is roughly .100 to .560. Wait for at least 100 at-bats before drawing conclusions, and 500+ for a meaningful season-level read.
Always check OBP alongside batting average. A .250 hitter with a .350 OBP is producing; a .290 hitter with a .310 OBP isn't. The gap between BA and OBP — often called 'isolated patience' or 'walk rate proxy' — is one of the most stable predictive numbers in baseball.
Front offices and analysts use the slash line as a single quick summary. Saying a player is '.275/.350/.450' communicates contact, patience, and power in nine characters. Memorize a few reference lines: .240/.310/.380 is league average; .300/.400/.500 is elite.
Cricket averages aren't comparable across formats. Test averages above 50 are elite; T20 averages above 35 are elite. A T20 specialist with a 28 average might be more valuable in that format than a Test player with a 45. Always check what format an average is from.
A batter with many low-score not-outs (#10 and #11 batters often have 20*, 15* type innings) can have an inflated average. Some analysts compute a 'dismissals-only average' by treating not-outs as completed innings, especially when evaluating tail-end batters.
Batting average misses walks entirely and treats all hits equally. A player with a .280 BA and 80 walks creates more runs than a .300 hitter with 25 walks. Modern analysis treats BA as one input among several, not the headline number.
Walks, hit-by-pitch, sacrifice bunts, and sacrifice flies are not at-bats. They don't go in the denominator or numerator of batting average. If you're computing BA manually, make sure your AB number excludes these — many casual stat sites get this wrong.
A batter with 800 runs in 20 innings, 5 not-out, has 800/15 = 53.33 average, not 800/20 = 40.00. The not-out rule is fundamental — getting it wrong inflates your denominator and depresses every cricketer's average compared to their actual career numbers.
Baseball batting averages drop the leading zero — .275, not 0.275. Spreadsheets often store them as 0.275, which is mathematically correct but unconventional for the sport. When publishing, format with the leading zero stripped to match every box score and broadcast graphic.
League-wide batting average has fluctuated dramatically — .280 in the 1920s, .250 in the 1960s, back to .270 in the 1990s, around .245 today. A .300 in 1968 (the 'Year of the Pitcher') is more impressive than a .300 in 1930. Use OPS+ or wRC+ for cross-era comparisons; raw BA misleads.
Not since Ted Williams hit .406 in 1941. Several players have flirted with it — George Brett hit .390 in 1980, Tony Gwynn was at .394 in the strike-shortened 1994 season, and Larry Walker hit .379 in 1999. But the combination of better pitching, advanced defensive shifts, larger gloves, and improved scouting has made sustained .400 hitting essentially impossible at modern competition levels. Most analysts estimate the modern 'true talent' ceiling for batting average sits around .380.
Bradman's Test average across 80 innings (10 not-outs) means he scored roughly 100 runs every time he was dismissed across a 20-year career — through two world wars, multiple opposing teams' best efforts to defeat him, and the pre-WWII bumpy pitches. The next-highest career average among batsmen with 20+ Tests is around 60. The gap of nearly 40 runs is so vast that no rational extrapolation places a modern batter close to it. Sustained excellence at his level simply hasn't recurred.
OPS = OBP + SLG. The two are added directly even though they have different denominators (OBP uses plate appearances minus sacrifice bunts; SLG uses at-bats), which is a known mathematical inconsistency. Despite that, OPS correlates better with team runs scored than either component alone — it's a useful shortcut that sacrifices theoretical purity for practical predictive power. For more rigor, sabermetrics uses wOBA (weighted on-base average), which applies linear weights to each event type.
MLB requires 3.1 plate appearances per team game to qualify for the batting title. Over a 162-game season that's about 502 PAs. Players below that threshold aren't ranked even if their BA is higher — Tony Gwynn's .394 in 1994 didn't count for the batting title in some sources because the strike-shortened season changed qualification rules that year. Cricket uses different conventions per board; ICC typically requires a minimum innings count specific to the competition.
Yes — and elite seasons routinely do. The single-season OPS record is Barry Bonds' 1.4217 in 2004. Babe Ruth recorded multiple seasons over 1.300. In 2024, Aaron Judge posted a 1.156 OPS. An OPS above 1.000 is roughly a once-per-team-per-decade event for non-MVP players, and routine for MVP candidates. The theoretical maximum is 5.000 (every PA a walk or home run with sufficient power), but no player has come close in practice.
Batting average is hits divided by at-bats — BA = H / AB. Walks, hit-by-pitch, sacrifice bunts, and sacrifice flies do not count as at-bats, so they don't affect batting average. The result is displayed to three decimals with no leading zero: a player with 50 hits in 200 at-bats has a .250 average, not 0.250. The convention dates back to the late 1800s when batting averages were already widely tracked.
.300 is the traditional threshold for an excellent hitter — only about 20–30 qualified MLB players hit .300 in any given season. League average has hovered around .240–.260 for the past decade. Anything above .250 is solid, .275+ is good, .300+ is excellent, and .350+ is historic territory. The all-time single-season record is Hugh Duffy's .440 in 1894; in the modern era (post-1900), Ted Williams' .406 in 1941 was the last .400 season.
Batting average only credits hits. On-base percentage (OBP) credits any way of reaching base without an error — hits, walks, and hit-by-pitch — divided by plate appearances. Slugging (SLG) weights extra-base hits: a single = 1 base, double = 2, triple = 3, home run = 4, all divided by at-bats. OPS is just OBP + SLG, a quick composite stat. A .250/.350/.450 slash line means .250 BA, .350 OBP, .450 SLG, and an OPS of .800.
Cricket divides total runs by dismissals (not innings). If a batter scores 1000 runs across 25 innings with 5 not-outs, their average is 1000 / (25 - 5) = 50.00. The not-out convention exists because a batter who hasn't been dismissed could theoretically score more — the innings was cut off by the team total or end of match. Cricket averages run much higher than baseball — Don Bradman's 99.94 is the gold standard.
No — and that's correct. The official OBP formula excludes sacrifice bunts (SH) from the denominator because the batter was deliberately giving themselves up to advance a runner. Only sacrifice flies (SF), which exist exclusively in fly-ball form, count in the denominator. The formula is (H + BB + HBP) / (AB + BB + HBP + SF). MLB has used this version since 1984.
OPS+ is a park-and-league-adjusted version of OPS, scaled so that 100 = league average. An OPS+ of 150 means 50% better than league average. The raw OPS this calculator produces is the un-adjusted version. To get OPS+, you need league averages and ballpark factors, which is why specialized sites like Baseball-Reference publish OPS+ — it can't be computed from a single player's line alone.
Modern analytics (sabermetrics) argues batting average gives equal weight to all hits and ignores walks. A leadoff hitter with 80 walks and a .260 BA might be more valuable than a free-swinger with a .300 BA and only 20 walks, because the walks-to-strikeouts ratio strongly predicts runs scored. That's why OBP and OPS have largely replaced BA in front offices — Moneyball was essentially the story of the Oakland A's exploiting this gap before it was widely understood.
Yes — softball uses the same BA / OBP / SLG / OPS formulas as baseball, so the baseball mode works directly. For cricket-style scoring (T20, ODI, first-class), use the cricket mode. The calculator doesn't have specific modes for stickball or vintage base ball, but the formulas are identical. Any sport where 'hits / at-bats' is the basic rate stat will work in baseball mode.
Formulas reflect current MLB and ICC official scoring rules. Historical statistics are sourced from Baseball-Reference and ESPNcricinfo at time of publication.
