Hi Sumatra,
as BYVeterangirl and B Sousa state, there are too many variables.
If you are still earning, you'll most likely be in the top 5% of income earners - but the spending patterns of these people is different to those who have plenty of accumulated wealth - usually older people who are well-to-do and are not aspirational any more.
I used to do this sort of analysis for a living, but you'd best PM me if you need to know more.
Cheers
