Two concerns with that - the first is that there are a lot of personal assumptions you have to make and then stick to in order to make the math useful (how long are you going to live, # of kids, SBP, etc). The second is that looking at somebody else's can influence your assumptions to the point of making them somewhere between non-applicable to outright misleading.
Having said that, if I get the opportunity I will try to make a more generic one that more people could find useful. Also, if anybody has sat down and calculated it for themselves I'll be happy to do the same thing I did for my LT and look at it and tell you what I think.
(As a side note, my credentials for offerring to do that are that I have been a college math professor, and my own financial decisions/calculations led me to choose a particular form of career suicide which I have been very happy with).
EDIT: Since I was threadjacking a bit anyways, I will add this. Part of the exercise I put him through was also designed to teach him a bit more of using spreadsheets. What he put together was intuitive for him, but would take a bit of effort to become adaptable for others. On top of the personal financial end of the discussion, I think it was pretty helpful for him in understanding what it takes to make a spreadsheet useful for your boss as a decision making aid (ease of use and flexibility/transparency of changing assumptions, for instance). Being as I am a bit tired of getting briefs that are essentially randomly-colored-8-pt-fonts-o-crap I figured it to be good training all around...
