Definition – What is Simple Isolated Power?

Isolated Power (ISO) represents a player’s ability to hit for extra bases.

A player with a higher ISO is seen as producing more multiple base hits. It is typically used to compare two batters with similar batting averages.

Formula – How to calculate ISO

ISO = Slugging Percentage – Batting Average


If 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
