Correct me if I'm wrong on the following calculation....
140% Debts/Disposable Household Income
If Mr Z debt amt 300,000
Disposable Income = 300,000/1.4 = 214,285 (Annual income after Tax)
Mr Z monthly income = 214,285/12 = 17,857 (after tax)
300,000 monthly payment est 1,500, I'll round off to 2,000
Mr Z income for other expenses after debt payment monthly = 17,857 - 2,000 = 15,857
I'm not into economic study or whatsoever, jus wonder anything wrong on my calculation?

And this does not included or concern on assets value too right? If the asset value 1,000,000 now?

Calculation looks fine but assumption that household consists of one person may not be true... .... Nice try though... Lol!!! Buy buy buy tomorrow prices going up... Hehe
