About Home Affordability Calculator

The golden rule of home buying is that your monthly housing costs should not exceed 28% of your gross monthly income, and your total debt payments should stay under 36%. Those are the front-end and back-end ratios lenders use to qualify you for a mortgage. But knowing the math is one thing — applying it to your actual numbers is where most people get stuck.

This calculator works backwards from your income and existing debts to tell you the maximum home price you can realistically afford. It factors in property taxes, insurance, and your down payment so there are no surprises when you sit down with a lender. Keep in mind that just because a bank says you qualify for a $450,000 house doesn not mean it is a good idea. Your comfort zone might be lower — and this tool helps you find that number.
