# How to calc % change from calculated expressions?

Hello - relatively new to QV.  I'm trying to figure out how to calculate a growth metric (% growth from prior year for example) for selected fields within qv.  I created a couple simple charts (attached) from an excel data source, where the data from excel is organized as follows (example has three years of data through 2010):

 Country Year Units Revenue Region US 2008 1,000.00 1,000.00 N AMERICA Canada 2008 200.00 180.00 N AMERICA UK 2008 300.00 180.00 EUROPE Spain 2008 350.00 262.50 EUROPE Italy 2008 275.00 206.25 EUROPE

How can I calculate year over year % changes in units and revenues for selected fields?  Within the attached, if you filter on "N America", you would see revenues of 1180, 1330 & 1406.9 for 2008-2010 respectively.  I would like to calc and show the growth metrics of 12.7% (2008 - 1180 to 2009 - 1330) and 5.8% (2009 - 1330 to 1406.9) for 2009 and 2010.

See attached qvw. Is that close to what you're looking for?

Thanks Gysbert, exactly what I needed.  Of course it's this simple - I appreciate the help!

Sorry for the bother, but just to piggy back off of this question - is there a way to create analyses by utilizing the % growth as the basis?  For example (and using the attached) is there a way I could list the top 3 countries that had the largest % revenue growth from 08 to 09?  09-10?  Or even 08 to 10?
