House Affordability Calculator
Estimate the home price you can afford based on income and down payment.
"How much house can I afford?" is the first question of home buying, and the answer combines your income, your down payment and prevailing lending rules. A common rule of thumb caps the home price at three to five times annual income, adjusted for your down payment — a quick sanity check before you get pre-approved for the precise figure.
Enter your annual income and down payment, and this calculator estimates an affordable home price range using conservative and stretched income multiples. Treat it as a starting point; a lender's pre-approval accounts for your debts, credit and the exact interest rate.
