Understanding Your Home Loan Amortization
A mortgage is typically the largest financial liability an individual assumes. Learning how principal, interest compounding, and escrow payments interact can save tens of thousands of dollars over the lifetime of the loan.
1. What is Amortization?
Amortization is the systematic repayment of loan principal and interest over a predefined term. In the early years of a 30-year loan, the majority of each monthly payment goes towards interest. Over time, as the principal balance declines, a larger portion of every payment is applied directly to equity.
2. How do Extra Payments Save Money?
When you make an extra payment earmarked for principal, it bypasses interest compounding and directly reduces the outstanding loan balance. Future interest is then calculated on the smaller balance, compounding savings and reducing your loan term by years.
3. 15-Year vs. 30-Year Fixed Mortgages
A 15-year fixed mortgage offers lower interest rates and saves enormous amounts of total interest compared to a 30-year mortgage, but requires higher mandatory monthly cashflow. A 30-year mortgage offers budget flexibility with the option to voluntarily overpay.
4. What is PITI?
PITI stands for Principal, Interest, Taxes, and Insurance. Most mortgage lenders require borrowers to pay one-twelfth of their estimated annual property taxes and homeowners insurance into an escrow account alongside the core loan payment.
