What is Simple Isolated Power?

Isolated Power (ISO) is a baseball hitting metric that attempts to isolate a player’s ability to hit for extra bases.
It is calculated by subtracting a player’s Batting Average from their Slugging Percentage.
A player with a higher ISO is seen as producing more multiple base hits than another player with a lower ISO but equivalent batting average.

How to calculate ISO

In Baseball, simple isolated power is calculated as:
ISO = Slugging Percentage – Batting Average


If a a player has a batting average of 0.288 and a slugging percentage of 0.455, then:
ISO = 0.455 – 0.288
ISO = 0.167
This batter’s ISO is 0.167
