What this calculator does
The Home Affordability Calculator estimates a housing budget from income, debt obligations, down payment, interest assumptions, and other inputs available on the page. It is intended for preliminary planning, not mortgage approval.
How to use the calculator step by step
Enter gross income, recurring debt payments, available down payment, estimated interest rate, and housing costs requested by the form. Test more conservative scenarios instead of treating the maximum result as a spending target.
How the calculation works
Affordability estimates commonly compare proposed housing costs and existing monthly debt with gross monthly income, then estimate a mortgage amount consistent with the selected ratios and loan assumptions.
Worked example and scenario testing
Two households with the same income can receive very different affordability estimates if one has high recurring debt or a smaller down payment. Interest rates also strongly affect how much principal fits within the same monthly payment.
How to interpret your result
The displayed home price or loan amount is a mathematical estimate. A comfortable personal budget may be lower after accounting for savings goals, childcare, repairs, transportation, and other expenses.
Accuracy, assumptions, and limitations
Lenders use their own underwriting standards and may consider credit history, employment, assets, reserves, taxes, insurance, association dues, mortgage insurance, and loan-program requirements.
Common mistakes to avoid
Do not treat the highest estimated price as the amount you should spend. Also include realistic taxes, insurance, maintenance, and other ownership expenses in your budget.
