Net Monthly Income

Gross pay shrinks on its way to your account: federal and state taxes, FICA, retirement contributions, and health premiums all come out before you see a dollar. Because net is always smaller than gross, a payment sized against gross income takes a strictly larger share of the money that actually lands in your account.

That is why budgeting against net income is the more honest comfort check. A lender approves you on gross-income ratios, but the mortgage gets paid from take-home pay alongside groceries, childcare, and savings. Anchoring your housing decision to net income, and to the cushion you want left over, helps you avoid stretching to a payment that technically qualifies yet leaves you feeling house poor. The right share for you varies with your goals and other expenses.
