taxable family income?

A taxable personal income of 75 k pa is pretty good. Assuming a tax rate of 25% one can get about 4500 dollars monthly. This is fantastic.

In case it is for a family annual income, it is a bit tough. Again at a tax rate of 25% a family will get 4500 dollars per month. But there are more consumptions, like mortgage, child care, food, insurance, medication, etc. 

Ai, life is not easy.
