Batting Average Calculator

Batting average is hits divided by at bats. For example, 150 hits in 500 at bats is 150 / 500 = 0.300, written as .300. The value always falls between .000 and 1.000 because hits can never exceed at bats.

Baseball convention drops the leading zero, so 0.300 is written .300 and read aloud as three hundred. This tool follows that convention in the .XXX card while the Decimal card keeps the leading zero and shows four places.

The .XXX display rounds to three decimal places, so .3335 and above round up. The Decimal card shows four places, which is why 100 hits in 300 at bats reads .333 and 0.3333, since one third is a repeating decimal.

An at bat is a plate appearance that ends in a hit, an out, or a reached-on-error. It excludes walks, hit by pitch, sacrifice bunts and flies, and catcher interference, which count as plate appearances but not at bats. Enter official at bats, not total plate appearances.

In modern Major League Baseball a .300 average is excellent, roughly .250 to .270 is around league average, and below .200 is poor, a threshold nicknamed the Mendoza line. Youth and amateur leagues often run higher.

No. Every hit is also an at bat, so hits can never exceed at bats. If you enter more hits than at bats the calculator shows an error message instead of a number, and it also rejects zero at bats since dividing by zero is undefined.

Not entirely. Average treats a single and a home run the same and ignores walks. On-base percentage and slugging percentage capture those, and OPS combines them, which is why many analysts prefer them for judging a hitter's total value.

Both fields accept whole numbers from 0 up to 1000. A batter with as many hits as at bats scores a perfect 1.000, which the tool shows as 1.000 with the leading digit kept rather than dropped.

No. The division runs in your browser as you type, so the hits and at bats you enter stay on your device and are never sent to a server or stored.
