Loan Amortization Calculator

What is a Loan Amortization?

Loan amortization is the process of paying off a loan through regular, scheduled payments over time. Each payment covers the interest charged for that period plus a portion of the outstanding principal. The key insight of amortization is that in early payments, the interest portion is very large and the principal portion is small. As the outstanding balance reduces over time, the interest charge decreases and more of each payment goes toward reducing the principal. By the final payment, almost all of it is principal. This is why paying off a loan early saves so much interest — you skip the later payments where more goes to principal.

💡 Pro Tips

• ✓Making extra payments toward principal in the early years of a loan saves the most interest.
• ✓Refinancing to a lower interest rate is most beneficial in the first half of a long loan when interest payments dominate.
• ✓Even one extra monthly payment per year — a common trick — can cut years off a 30-year mortgage.
• ✓Compare the total interest cost between a 5-year and 10-year loan — the difference is often shocking.
• ✓Ask your bank for a full amortization schedule to see every payment broken down over the entire loan life.
