What is Equivalent Average?

Equivalent average is a hitting metric in baseball intended to show a player’s hitting ability independent of park and league effects.
EqA creates a number on a scale similar to that of Batting Average (BA).
EqA is often used to compare hitting ability across leagues, for example between minor and major leagues.
It was renamed to True Average (TAv) in 2010.

How to calculate EqA

In Baseball, Equivalent Average is calculated as follows:
Equivalent Average = (Hits + Total Bases + (1.5 x (Walks + Hit by Pitch)) + Stolen Bases + Sacrifice Hits + Sacrifice Flies) / (At Bats + Walks + Hit by Pitch + Sacrifice Hits + Sacrifice Flies + Caught Stealing + (Stolen Bases / 3))
Equivalent average is listed to 3 decimal points.

Example

A batter has the following statistics: Hits: 164 | Total Bases: 255 | Walks: 22 | Hit by Pitch: 4 | Stolen Bases: 18 | Sacrifice Hits: 6 | Sacrifice Flies: 18 | At Bats: 520 | Caught Stealing: 7 | Stolen Bases: 18
EqA = (164 + 255 + (1.5 x (22 + 4)) + 18 + 6 + 18) / (520 + 22 + 4 + 6 + 18 + 7 + (18 / 3))
EqA = (164 + 255 + (1.5 x 26) + 18 + 6 + 18) / (520 + 22 + 4 + 6 + 18 + 7 + 6)
EqA = (164 + 255 + 39 + 18 + 6 + 18) / (520 + 22 + 4 + 6 + 18 + 7 + 6)
EqA = 500 / 583
EqA = 0.858
Therefore, the pitcher’s Equivalent Average (EqA) is 0.858
