Simplicity is good. Rough estimates are good enough for much of what we need to do. But sometimes it helps to know things more accurately. Using a program like Microsoft Money or Quicken is even simpler than the back of the envelope method after you've entered the information one time. You don't have to find an old envelope in the trash, brave the bacteria, remember all of your investments, remember what they are worth, or even remember to carry the 1 to the next column. Results are updated and computed automatically and you can even look at them graphically.youbet said:What I like best about John's method is that there is no updating/refreshing of asset values. Simply SWAG with your best recollection of the value of equities, real estate, etc., and add it up. If your best recollection/knowledge of the value of your home is what you paid for it ten years ago, so be it! Just write it down and add 'em up! Keeps it simple.
