How Batting Average Is Calculated

BA = Hits ÷ At-Bats. It is always expressed as a three-decimal number — .283 means 283 hits per 1,000 at-bats (28.3% success rate). Batting average does not count walks, hit-by-pitches, sacrifices, or errors — only actual hits divided by at-bats. On-Base Percentage (OBP) is a better overall measure because it includes walks: OBP = (H + BB + HBP) ÷ (AB + BB + HBP + SF).

What Is a Good Batting Average?

.300+: Excellent — All-Star level, only ~20-30 players per season. .270-.300: Above average, solid everyday player. .250-.270: League average. .220-.250: Below average but may contribute power/defense. Below .200: The "Mendoza Line" — below this, a player job is in jeopardy. The MLB-wide batting average has hovered around .240-.250 in recent years, down from .270+ in the early 2000s.

Frequently asked questions

What is a good batting average?▾

In MLB: .300+ is excellent (top ~10% of regulars), .250 is average, below .200 is the "Mendoza Line." In college baseball, averages run 15-20 points higher. In Little League, .400+ is common due to lower pitching quality. Always compare within the same league level.

Is batting average or OBP more important?▾

OBP is more valuable because walks have nearly the same value as singles. A player hitting .250 with a .370 OBP (lots of walks) is more valuable than one hitting .280 with a .310 OBP. This is the core insight of Moneyball — OBP was the most undervalued stat in baseball.
