Income Required for a Mortgage Calculator
Lenders approve you based on ratios, so a given house payment implies a minimum income. Enter the monthly housing payment (with taxes and insurance) and your other debts to see the gross income needed under the standard 28% and 36% limits.

How this calculator works
Required monthly income is the larger of two figures: housing payment ÷ front-end limit, and (housing + other debt) ÷ back-end limit. The binding ratio is whichever produces the higher requirement. Annual income is the monthly figure × 12.
Uses gross (pre-tax) income, as lenders do, and the ratios you set (28/36 by default). It's the inverse of the affordability calculator — that one turns income into a price; this turns a payment into the income needed.
What this assumes
- The 28/36 ratios lenders traditionally use, applied to gross income before tax.
- Existing debt payments count in full regardless of remaining balance — lenders count payments, not balances.
- Living costs that are not credit obligations — childcare, utilities, groceries — are excluded, exactly as an underwriter excludes them.
What changes this number
- Existing debt payments
- Decide which ratio binds. If the back-end binds, clearing a debt raises the answer more than earning more.
- Interest rate
- Changes the payment a given income supports, so the required income moves with the market rather than with the house.
- Property tax and insurance
- Counted inside the housing ratio, so a high-tax state requires meaningfully more income for the same price.

Frequently asked questions
How much income do I need to buy a house?
Enough that your housing payment stays under about 28% of your gross income and your total debt under about 36% — the classic lender ratios. For a $2,000 monthly payment with no other debt, that's roughly $2,000 ÷ 0.28 ≈ $7,150 a month, or about $86,000 a year. Other debts raise the requirement.
What is the 28/36 rule?
A guideline lenders use: your housing costs should stay under 28% of gross monthly income (the front-end ratio), and all debt payments combined under 36% (the back-end ratio). Whichever limit you hit first determines how much income you need — this calculator flags the binding one.
Does the required income include my down payment?
No — this is about qualifying for the monthly payment, not the cash to close. A bigger down payment lowers the loan and therefore the payment, which lowers the income you need. Use the affordability and down-payment calculators to connect the payment, the price, and the cash required.
Can I qualify with a lower income than this shows?
Sometimes. Lenders may stretch the ratios — FHA loans often allow higher back-end ratios — if you have strong credit or large cash reserves. But qualifying at a higher ratio means a tighter budget. This calculator shows the income for a comfortable, standard approval.
