Places to Find Good Financial Data

As with many folks, I like to track and chart financial data trends.  Spreadsheets are fun!  Over the years I have found many good places to get solid data.

Here are some of the trends I track:
You can see the trends I produce by visiting the opening page of kietzman.org.  The tool is capable of forecasting trends by analyzing past data.  Future rates are determined using average annual rates over a given historical period.  The determined future rate is then used to forecast future trends via the following formula:

F=P*(1+(R))^Y

F:  future amount
P:  principal amount
R:  annual rate
Y:  number of years

Using this kind of data and the trends they produce, you can estimate how your investments will perform over the long run even against inflation.
