Mortgage affordability calculator
Mortgage Affordability Calculator
Estimate how much house you may be able to afford based on income, monthly debts, down payment, interest rate and debt-to-income ratio.
How this mortgage affordability calculator works
This calculator estimates how much home you may be able to afford by using income, existing monthly debt payments, down payment, interest rate and a debt-to-income limit.
What is debt-to-income ratio?
Debt-to-income ratio compares monthly debt payments with monthly income. Lenders often use this ratio when reviewing mortgage applications.
Why down payment matters
A larger down payment can increase estimated home affordability because it reduces the loan amount needed to buy a home.
Interest rates affect affordability
Higher interest rates usually reduce affordability because they increase the monthly payment for the same loan amount.
