From the OP's post it appears what he is looking for is comparing how he is doing to others on the board.
The problem with using net worth is, we are all different.
Examples: All have a net worth of 2 million
A. Has 1.9 mill in the bank and 100,000 is personal property, with no debt. His income in retirement is generated by the 1.9 mill is is $80,000 a year.
B. Has 0 in the bank and no debt and 100,000 personal property. He has $80,000 a year of cola'd income from gov. and tripple A rated companies.
C. Has 1 mill in the bank, 1 mill in assets, 1 mill in debt, but gets $40,000 in cola'd pension, and $40,000 from invested 1 mill.
So,
A has a net worth of $2 mill., and a secure retirement of $80K
B has a net worth of $100K and a secure retirement of $80K
C. has a net worth of $1 mill. a secure retirement of $80K
However, without more information we still cant say A is better off. You see A has a very young new wife and his expenses are well over $80k a year, B is a bachelor and and has expenses of $20k a year, and C has expenses of $80K a year.
So while A has the highest net worth, B the lowest, and C in the middle, if you were to compare their financial situation, B with a $0 net worth, is the best off. But this may not even be true, as we did not know that B is about to get married, and have an instant family of five, with three kids to send to college!
Bottom line, I know where I am. I am better off than some of my friends and neighbors, and worse off than others. I am 98% sure my retirement is secure, and I will not out live my income. (I really think it is 100%, but hyper inflation, war, some sort of natural disaster etc. might change things. These are out of my control and I just don't really worry about them)
I think I could go on for a long time changing what A, B, and C have, or facing, but you should get the point. Maybe a better number would be "How confident are you in your financial future". For me that number is 98%.
