What is discretionary income?
Discretionary income is the money left over after paying taxes and covering essential living costs like housing, food, and utilities. It’s the amount you’re free to spend, save, or invest as you choose, and is often used to determine loan repayment plan eligibility.
The formula
Discretionary Income = Gross Income − Taxes − Essential Living Expenses. The calculator also shows this as a percentage of your gross income for easy comparison across pay periods.
