How much house can I afford?

Lenders commonly use the 28/36 rule: housing costs should stay under 28 % of gross monthly income, and all debt payments including housing under 36 %. The lower limit sets your maximum monthly payment and therefore the loan size.

How the estimate works

  1. Your maximum housing payment is the lower of 28 % of monthly income and 36 % minus your other debts.
  2. Property tax and insurance are subtracted to get the principal-and-interest budget.
  3. That budget is turned into a loan amount at your rate and term; adding the down payment gives the home price.

Adjust the 28/36 limits if your lender uses different ratios (some allow 31/43). Also budget for closing costs, maintenance and an emergency fund. Calculate the payment for a specific loan with the Loan EMI Calculator.
