I know this sounds like a math problem, but I am really wondering if there is an Excel shortcut.

So I have different weights for the months through out the year:

How do I annualize that if I have Jan February data? Wasn't sure if there was a shortcut...I tired to google it and it came back with "climate of India" o_O

I hope this isn't a stupid question...

Hi Kristin,

Maybe like this:

Code:
       -A- -B- C -D- -----------------------E------------------------
   2   Jan  5%   100 D2: Input                                       
   3   Feb  8%   150 D3: Input                                       
   4   Mar  9%   173 D4 and down: =SUM($D$2:$D$3)/SUM($B$2:$B$3) * B4
   5   Apr  7%   135                                                 
   6   May  9%   173                                                 
   7   Jun 11%   212                                                 
   8   Jul  8%   154                                                 
   9   Aug  7%   135                                                 
  10   Sep  8%   154                                                 
  11   Oct  9%   173                                                 
  12   Nov  7%   135                                                 
  13   Dec 11%   212

This part could just go in a separate cell instead of calculating repeatedly:

=SUM($D$2:$D$3)/SUM($B$2:$B$3)
