<math>BAA = \frac{H}{BF-BB-HBP-SH-SF-CINT}</math>

for which:
*H is the number of [[hit (baseball)|hit]]s allowed by the pitcher
*BF is the number of [[batters faced]]
*BB is the number of [[base on balls]]
*HBP is the number of [[hit by pitch|hit batsmen]]
*SH is the number of [[sacrifice hit]]s
*SF is the number of [[sacrifice fly|sacrifice flies]]
*CINT is the number of [[catcher's interference]]

For example, if a pitcher faced 125 batters and allowed 25 hits, issued 8 walks, hit 1 batsman, allowed 2 sacrifice hits, allowed 3 sacrifice flies, and had 1 instance of catcher's interference, the pitcher's BAA would be calculated as:

<math>BAA = \frac{25}{125-8-1-2-3-1} = \frac{25}{110} = .227</math>


Reference site [[Baseball-Reference.com]] more simply defines BAA as hits divided by [[at bat]]s, as "at bats" for a pitcher equates to the above noted denominator (batters faced less walks, hit by pitch, sacrifice hits, sacrifice flies, and catcher's interference):<ref name=br2021/>{{efn|See section "Player Batting Against", hover over "BA" column header.}}

<math>BAA = \frac{H}{AB}</math>

For example, in 2021, [[Max Scherzer]] had the best (lowest) batting average against in [[Major League Baseball]] among qualified pitchers.<ref name=br2021>{{cite web |url=https://www.baseball-reference.com/leagues/majors/2021-batting-pitching.shtml |title=2021 Major League Baseball Batting Against |website=[[Baseball-Reference.com]] |accessdate=June 4, 2022}}</ref>{{efn|See section "Player Batting Against", sort by column "BA".}} Scherzer's BAA for the 2021 season was:<ref name=br2021/>

<math>BAA = \frac{H}{AB} = \frac{119}{644} = .185</math>
