How This Calculator Works

The estimate applies your DTI limit to gross monthly income, subtracts existing monthly debt payments, and calculates the mortgage principal supported by that payment over the selected term. It excludes property taxes, insurance, HOA fees, and other ownership costs.

Mortgage Affordability Estimate

Housing Budget = Monthly Income × DTI Limit − Monthly Debts; Loan = Present Value of Monthly Payments

Frequently Asked Questions
