How Loan Affordability Is Calculated

This calculator uses the standard debt-to-income (DTI) ratio framework used by most lenders. Your maximum monthly loan payment is determined by subtracting your existing debt payments from your target DTI amount. That payment is then used to calculate the maximum loan principal using the standard present value of annuity formula.
