I'm single, didn't use pension (not sure what that would be for NW anyway). I came out at 95.52%. If I pretend I'm part of a couple, and leave everything (but retirement) the same, add that this imaginary person has the same retirement savings I do, it only goes up to 97.86%. If I double my NW (not sure that would be correct, because same house, but whatever, it's over 7 figures), it stays at 97.86%(?!)
Apparently there is some rich-as-hell 38-year-old mofo out there.
