What is Amortization?

Amortization is the process of paying off a loan in equal installments over time. Each payment covers interest and reduces the principal. Early payments are mostly interest; later payments are mostly principal.

How Amortization is Calculated

The standard formula for a fixed-rate loan is:

P = (L × r × (1 + r)^n) / ((1 + r)^n - 1)
  • P = monthly payment
  • L = loan amount (principal)
  • r = monthly interest rate (annual rate / 12 / 100)
  • n = number of monthly payments (term)

Example: $10,000 loan, 6% interest, 5 years

r = 0.06 / 12 = 0.005\nn = 60\nP = (10,000 × 0.005 × (1 + 0.005)^60) / ((1 + 0.005)^60 - 1) ≈ $193
(Actual result may vary slightly due to rounding.)

Why Amortization Matters

  • Understand how much interest you pay over the life of a loan.
  • See how extra payments reduce interest and shorten the term.
  • Compare different loan options and terms.

Tips for Managing Loans

  • Make extra payments to save on interest.
  • Refinance if you can get a lower rate.
  • Understand your amortization schedule before borrowing.

Frequently Asked Questions (FAQ)

Q: What loans use amortization?

A: Mortgages, auto loans, personal loans, and most installment loans use amortization.

Q: Can I pay off my loan early?

A: Yes, but check for prepayment penalties. Early payoff saves on interest.

Q: Why do early payments have more interest?

A: Because interest is calculated on the remaining principal, which is highest at the start.

Q: How do extra payments affect amortization?

A: Extra payments reduce principal faster, saving interest and shortening the loan term.
