PERSONAL INCOME AND DISPOSABLE INCOME: Personal income (PI) is the total income received by the members of the domestic household sector, which may or may not be earned from productive activities during a given period of time, usually one year. Disposable income (DI) is the total income that can be used by the household sector for either consumption or saving during a given period of time, usually one year. Disposable income is after-tax income that is officially calculated as the difference between personal income and personal tax and nontax payments. In the numbers game, personal tax and nontax payments are about 15% of personal income, which makes disposable personal income about 85% of personal income.
