Calculation Methodology & Formula
Computes fixed periodic debt amortizations using the standard annuity formula. Each payment covers the monthly interest on current balance, with the remainder reducing the loan principal. Supports 0% interest zero-APR promotions.
EMI = P × r × (1 + r)^n / ((1 + r)^n - 1)Worked Example: 30-Year Fixed Mortgage Amortization
$300,000 principal at 6.5% interest over 30 years.
Total payments over 360 months equal $682,633 ($300k principal + $382,633 total interest).
Technical Constraints & Limitations
- Assumes a fixed interest rate throughout the loan term; adjustable rate mortgages (ARM) vary over time.
- Excludes property taxes, homeowner insurance (PITI), HOA dues, and origination closing fees.
