Step-by-step explanation:
Total personal revenue is the disposable income less personal taxes. Employee earnings minus employee actual taxes in terms of national reports reflect net established income.
The household saving rate is specified as total saving divided by disposable income.
Household saving = Disposable income * Households saving rate
