title: Calculating percent change in Excel Pivot Table
body: <p>Using standard Excel 2010 I am trying to calculate percent change from 2013 to 2014 and put that in a column after grand total.</p>
  
  <p>The formula I am trying to use is <code>(2013 - 2014) / 2013</code></p>
  
  <p>I have tried <em>Calculated Field</em> but that hasn't worked, and I can't do <em>Calculated Item</em> since I grouped my dates to show in years instead of days.</p>
