What Is Disposable Income?

Disposable income is the income a household has left after paying income taxes and mandatory payroll contributions. It is available for spending and saving. Discretionary income is narrower: what remains after both taxes and essential living costs such as housing, food, and utilities.

Disposable vs. Discretionary Income

Disposable income = gross income − taxes. Discretionary income = disposable income − essential expenses. Discretionary income is what is available for wants, extra savings, or extra debt payments.

Why It Is Measured

Economists track disposable income to understand consumer spending and saving across an economy.
