Home Affordability Calculator
Find out how much house you can afford based on income, debts, and down payment.
How Home Affordability Is Calculated
Lenders typically use the 28/36 rule: your housing payment (including taxes and insurance) should not exceed 28% of your gross monthly income, and your total debt payments should not exceed 36%. This calculator uses the 28% front-end DTI ratio to determine the maximum monthly payment, then calculates the maximum loan amount using the standard mortgage formula.
