I also aim for 7-10% myself but accounting for inflation, my returns have been 5% so far (from 1998)
Saving rate also widely range from 10% to 90% in the MMM community, don't know what's the average but 75% seams high
I think net worth is a bit correlated with age. i.e. 22 y.o. with 100k is a lot better than 55 y.o. with that same 100k don't you think?
Bottom line, I knew we were doing well compared to neighbors, friends, related but not THAT MUCH.
matchewed is right, I ran those numbers a bit to fast but, 10x is still KICKASS for the same income range !
Bob is 2.5x better than me so, depends who you compare to.
Even with my "wrong" statement calculation etc, in some case, it could be 100x & more compared to the SAME situation (income, age, kidz#, house size etc) who knows...
