How this calculator works

Estimate a planning home-price range from income, monthly debts, down payment, interest rate and a target debt-to-income ratio. It uses the values you enter and shows the main components separately so you can review the estimate rather than relying on one unexplained number.

Formula

Maximum housing payment = gross monthly income × target DTI − other monthly debt; estimated loan principal is derived from the payment.

Example

The estimate converts the payment available for principal and interest into a loan amount, then adds the entered down payment.

How to improve the estimate

This is a planning estimate, not a lender preapproval.
Use realistic taxes, insurance, HOA and mortgage insurance costs.
Keep cash for closing costs, repairs and an emergency reserve.

Understanding the result

The result is for comparison and planning. Actual bills, lender calculations, taxes, fees, employment rules or contract terms may differ. Verify important decisions with the relevant provider, lender, employer, tax authority or other authoritative source.

Frequently asked questions

What is DTI?

Debt-to-income ratio compares recurring monthly debt payments with gross monthly income.

Does this guarantee approval?

No. Loan programs and lenders also evaluate credit, assets, property, employment and documentation.

Are closing costs included?

No. Keep closing costs separate from the down payment entered here.
