What is Amortization?

Amortization refers to the process of paying off debt through regular payments over time, where each payment is split between principal and interest. Early in the loan, most of your payment goes toward interest, but that gradually shifts toward principal as the loan matures.

Examples

Example: Watching Your Equity Grow

A $200,000 loan at 4% interest for 15 years

After 5 years, you'll have paid off about $55,000 of principal, with about $145,000 remaining. By year 10, you'll have paid off approximately $125,000, with only $75,000 remaining.

Key takeaway: Loan equity builds more quickly in later years as more of each payment goes toward principal.

Accelerate Your Loan Payoff

Understanding your amortization schedule helps you identify opportunities to save on interest costs.

Look for opportunities to make extra principal payments during the early years of your loan when they have the greatest impact
Consider refinancing if interest rates have dropped significantly since you took out your loan
Track your equity growth to inform future financial decisions like home equity loans or selling assets
