Batting Average Calculator
Use this free batting average calculator to turn hits and at-bats into an accurate baseball or softball batting average in seconds, or flip it around to see exactly how many hits you’ll need over your next few at-bats to hit a target average.
Hits ÷ At-BatsWhere your average falls

Formula-verified
This batting average calculator uses the same hits-over-at-bats formula defined in official baseball scoring rules — no shortcuts, no rounding tricks.

A simple ratio, applied two different ways
Batting average is one of baseball’s oldest and simplest stats: hits divided by official at-bats, rounded to three decimals and read without the leading zero. It’s been tracked in some form since the earliest days of organized baseball in the 1870s, and it’s still the number most casually quoted on a broadcast or a stat card today. Its simplicity is also its limitation — walks, hit-by-pitches, and sacrifices don’t count toward it at all, so a batting average calculator like this one tells you how often contact turns into a hit, not overall offensive value.
This baseball batting average calculator handles both directions of the question. In Calculate Average mode, enter at-bats and hits to get the resulting average and a rough performance tier. In Hits Needed for Target mode, enter your current at-bats and hits plus how many at-bats remain, and the calculator works backward to tell you exactly how many more hits are needed to reach a specific average — useful for tracking a season goal, a milestone chase down the stretch, or simply understanding what a coach or scout means when they mention a target number.
Whether you’re a player checking your own numbers, a parent following a Little League or high school season, a fantasy baseball manager, or a coach doing quick math on the bench, this tool is built to give a clean, verifiable answer without ads getting in the way of the calculation.
How to calculate batting average, step by step
Batting average is hits divided by at-bats, rounded to three decimal places and written without the leading zero — a player who gets a hit 3 times in 10 at-bats is batting .300, not 0.300.
Batting average formula
Average = Hits ÷ At-Bats. A higher ratio means a hit is landing more often per official at-bat. This is the exact formula this batting average calculator applies.
Hits needed for a target
Needed hits = (Target × Total At-Bats) − Current Hits, rounded up, since a fraction of a hit isn’t possible.
Rough performance tiers
| Batting average | Tier |
|---|---|
| Below .230 | Below Average |
| .230–.260 | Average |
| .260–.290 | Good |
| .290–.320 | Very Good |
| .320+ | Excellent |
What this doesn’t include
Walks, hit-by-pitches, sacrifice bunts, and sacrifice flies — none of these count as at-bats, so they don’t factor into this ratio at all.
Step-by-step batting average calculation examples
Two examples — one straightforward average, one target-chasing scenario — using the same math the calculator above applies.
Straightforward average
“90 at-bats, 27 hits — what’s the batting average, and how good is that?”
Given inputs
- At-bats: 90
- Hits: 27
Computed outputs
- Average: 27 ÷ 90 = 0.300 → .300
- Tier: Very Good (.300 sits just below the .320 cutoff for the Excellent tier)
Chasing a target average
“I’m at 90 AB, 24 hits, with 10 at-bats left in the season. How many hits do I need to finish at .300?”
Given inputs
- Current AB / Hits: 90 / 24
- Upcoming AB: 10
- Target: .300
Computed outputs
- Total AB at season end: 90 + 10 = 100
- Hits needed: (0.300 × 100) − 24 = 6 hits
- 6 hits out of 10 remaining at-bats (a .600 finish) reaches exactly .300 — an ambitious but mathematically possible stretch run
Where batting average gets miscalculated
Using plate appearances instead of at-bats
Walks, hit-by-pitches, and sacrifices count as plate appearances but not at-bats. Dividing hits by total plate appearances instead of at-bats produces a lower number that isn’t actually batting average.
Forgetting the target must be mathematically reachable
If the hits needed to hit a target average exceeds the number of at-bats remaining, the target simply can’t be reached this stretch — this batting average calculator flags this rather than showing an impossible number.
Dropping the leading zero incorrectly
.300 is read as “three hundred,” not “point three.” Writing it as “3.00” or treating it as a whole number rather than a decimal under 1.000 is a common transcription error.
Treating batting average as the full offensive picture
Two players with identical batting averages can have very different overall value if one draws far more walks (higher OBP) or hits for more power (higher slugging). Batting average alone doesn’t capture either.
Comparing averages across very different sample sizes
A .400 average over 10 at-bats and a .400 average over 200 at-bats aren’t equally meaningful — small samples swing wildly with just one or two hits, so context on at-bat count matters when comparing.
