Understanding your result

This is a rough estimate; lenders also weigh credit, taxes, insurance and other factors.

Formula and method

Max monthly payment = income ÷ 12 × DTI − debts. That payment is converted to a loan amount using the mortgage formula, then the down payment is added for the price.

Assumptions and limitations

A simplified estimate using a debt-to-income limit. Lenders also weigh credit score, employment, property taxes, insurance and down payment, so a pre-approval is the real test.

Worked example

An 80,000 income with low debts and 40,000 down can often support a home in the low-to-mid 300,000s.

How to use this tool

  1. Enter your income and monthly debts.
  2. Add your down payment, rate, term and DTI limit.
  3. Press Calculate.

Common mistakes to avoid

  • Ignoring property tax and insurance, which reduce affordability.
