The latest Consumer Price Index (CPI) data is out and this is my monthly update to the projected annual inflation.
If you want more explanation of how I arrive at these numbers visit the May 2008 post. For information on why I am including the December 2007 numbers in these calculations see the June 2008 post.
The inflation so far for 2008:
Southeast = [ ( 212.65 – 203.457 ) / 203.457 ] * 100 = 4.518%
National = [ ( 218.783 – 210.036 ) / 210.036 ] * 100 = 4.165%

Estimated CPI when average change is applied to the rest of the year:
Est. Southeast CPI = 212.65 + ( 3 * 1.021 ) = 215.714
Est. National CPI = 218.783 + ( 3 * 0.972 ) = 221.699
Estimated inflation for 2008:
Southeast = [ ( 215.714 – 203.457 ) / 203.457 ] * 100 = 6.024%
National = [ ( 221.699 – 210.036 ) / 210.036 ] * 100 = 5.553%
