#### Formulas Used

1. Maximum Monthly Payment (DTI Method):

Front-End Limit = Gross Monthly Income × 0.28 Back-End Limit = (Gross Monthly Income × Max DTI) − Existing Monthly Debts Max Monthly Payment = min(Front-End Limit, Back-End Limit)

2. Maximum Loan Amount (Present Value of Annuity):

P = PMT × [1 − (1 + r)−n] / r

Where: PMT = max monthly payment, r = monthly interest rate (annual rate / 12), n = total number of payments (years × 12)

3. Total Interest: Total Paid − Principal = (PMT × n) − P
