Mortgage Affordability Calculator
See how much house you can realistically afford. Enter your income, existing monthly debts, down payment, interest rate and loan term, and the calculator applies the standard 28/36 debt-to-income rule to estimate your maximum monthly payment, loan, and home price.
Estimate based on the 28/36 rule (housing ≤28% of gross income, total debt ≤36%). Excludes property tax, insurance and HOA — your lender's limit may differ.
Frequently asked questions
What is the 28/36 rule?+
A common lending guideline: your housing payment should be no more than 28% of your gross monthly income, and your total debt payments no more than 36%. The calculator uses the lower of the two limits.
Does this include property tax and insurance?+
No — it estimates the mortgage principal and interest you can support. Property tax, home insurance and HOA fees come on top, so your true budget for the loan itself is a bit lower.
Should I borrow the maximum?+
Not necessarily. This shows an upper bound from the rule; a comfortable budget is often below it once you account for savings, lifestyle and other goals.
