# Equivalent Average (EqA) Calculator (aka True Average (TAv))

LAST UPDATE: September 24th, 2020

## Definition – What is Equivalent Average / True Average?

Equivalent average shows a player’s hitting ability independent of park and league effects.

It is similar to Batting Average (BA). A higher number means that the player hits more balls for each at bat.

EqA is often used to compare hitting ability across leagues, for example between minor and major leagues.

In 2010 it was renamed to True Average (TAv).

## Formula – How to calculate EqA

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
