Advanced affordability assumptions
How Much House Can I Afford?
Income and debt both matter
Debt-to-income ratio (DTI) compares monthly debt payments with gross monthly income. CFPB notes that mortgage products and lenders can use different DTI limits, which is why the assumptions in this calculator are editable.
Use the all-in housing cost
Principal and interest are only part of homeownership. Property taxes, homeowners insurance, HOA or condo fees and mortgage insurance can materially change the monthly cost.
Affordability is not approval
This tool estimates a price from the numbers you enter. Credit, reserves, loan type, underwriting rules and other factors can change what a lender will approve. Fannie Mae similarly describes affordability-calculator results as estimates rather than financing approval.
Budget beyond the mortgage
Closing costs, maintenance and emergency savings can affect what feels affordable even when a loan fits a DTI guideline. Use the optional budget and maintenance fields to make the estimate more personal.

Mortgage Affordability FAQ
What is included in the monthly housing estimate?
The estimate includes principal and interest, property taxes, homeowners insurance, HOA or condo fees, estimated PMI when applicable, and any optional maintenance reserve you enter.
What debts should I enter?
Enter recurring monthly debt obligations such as car loans, student loans, credit-card minimum payments and other debt payments that would be considered in your total monthly debt. Do not enter the new mortgage payment because the calculator adds the modeled housing cost separately.
Why can two affordability calculators give different answers?
They may use different DTI limits, interest rates, down payments, property-tax assumptions, insurance estimates, PMI assumptions or definitions of affordability. This calculator exposes those assumptions so you can replace defaults with figures that better match your situation.
Does a calculator tell me how much a lender will approve?
No. It is a planning estimate. Actual qualification depends on the lender, loan program, credit profile, documented income and assets, property details and underwriting.
