House Affordability Formula

Although lenders use several factors, affordability is generally estimated using your monthly income and debt-to-income (DTI) ratio.

Maximum Monthly Housing Payment = Monthly Income × Recommended Housing Percentage

Then,

Affordable Home Price = Loan Amount + Down Payment

The calculator automatically considers your interest rate, repayment period, taxes, insurance, and other housing costs to estimate a realistic purchase price.
