Home Affordability by Income Calculator
Enter gross monthly income, max DTI for housing (e.g. 28%), down payment %, rate, and term. See max home price and loan amount.
Max home price
Enter values to calculate.
How it works
Max P&I = income × (DTI/100). We solve for max loan from that payment using the standard formula, then max price = loan ÷ (1 − down%/100).
When to use it
Use it to set a price range before shopping or to see how income or DTI affects affordability.
Frequently asked questions
What DTI do lenders use?
Often 28% for housing only, or 36% total debt. Varies by lender.
Include taxes and insurance?
Lenders use PITI in DTI. This uses P&I only; use a lower DTI to leave room for T&I.
