Thanks for sharing the fruit of your labors Tim. I plan to use the spreadsheet as a starting point for planning my future purchaces. I did one "what if" today. I added 5, 10, and 20 years to retirements. As expected, the smaller the issue, the higher it climbed. That takes care of the supply. Now if we can just get subjective criteria included in the calculations.

FWIW
