Mortgage Affordability Calculator

Reviewed & updated by Updated Originally published

Buying a home is one of the biggest financial decisions you’ll make, and knowing how much house you can realistically afford is essential before applying for a mortgage. Our Mortgage Affordability Calculator helps you estimate an affordable home price based on your income, existing monthly debts, down payment, loan term, interest rate, and other housing expenses.

Instead of relying on rough estimates, this calculator considers important costs such as property taxes, homeowners insurance, HOA fees, and private mortgage insurance (PMI). It also evaluates your debt-to-income (DTI) ratio, a key factor that lenders use when determining mortgage eligibility.
