Mortgage APR Formula and Instructions
Method 1: Loan Principal and EMI
- Loan Amount = House Value - Down Payment.
- EMI uses standard amortization formula with monthly compounding.
Method 2: Fee Components
- Points fee = (Points / 100) x Loan Amount.
- Total fee = Loan Fee + Points fee + (PMI per year x years).
Method 3: APR (nominal and effective)
- Nominal APR solves for the monthly cost of credit (IRR) that discounts every monthly cash flow—principal & interest payment plus PMI/12—to the net loan amount after subtracting the dollar loan fee and points at closing. Expressed as an annual nominal rate (monthly IRR × 12).
- Effective APR (EAR) is (1 + monthly IRR)12 − 1.
- All Payments and Fees = mortgage payments + loan fee + points + total PMI (PMI per year × loan years).
