Use this free mortgage affordability calculator to estimate a home price based on your monthly income, existing debt, down payment, interest rate, and mortgage term. Adjust the figures to see how your estimated borrowing capacity and home-buying budget may change.
How Much House Can You Afford?
The home price you can reasonably afford depends on your income, debt obligations, available savings, mortgage rate, and repayment period.
This calculator uses a debt-to-income assumption to estimate the monthly amount available for a mortgage, then converts that amount into an illustrative loan estimate. Actual affordability may be lower after other housing costs are included.
How Income and Debt Affect Your Mortgage Budget
A higher income can increase the amount available for mortgage payments, while existing monthly debt reduces it. The calculator uses a 43% debt-to-income assumption, but lenders may apply different limits and consider other financial details. Treat the result as a starting point for budgeting rather than a guarantee that a lender will approve the estimated amount.
Understand Your Down Payment and Loan Amount
Your down payment reduces the amount you need to borrow and contributes to the total purchase budget. A larger down payment may also affect your loan-to-value ratio and whether private mortgage insurance is required.
Keep additional savings available for closing costs, moving expenses, property taxes, insurance, and ongoing home maintenance.
Compare Mortgage Terms and Monthly Payments
Changing your interest rate or loan term can significantly affect your estimated borrowing capacity. A longer term generally reduces the payment required for a given loan amount, while a higher rate increases it.
