  • Change payments frequency to see the effect on amortization.
  • Adding extra payments lowers interest paid and shortens the loan.

Understanding Loan Amortization

An amortized loan requires fixed periodic payments that cover both principal and interest. With each payment, you pay down the principal balance while also covering the interest charges. Our loan calculator helps you visualize this process with a detailed amortization schedule and chart.

Types of Amortized Loans

Many consumer loans fall into the category of amortized loans with regular payments spread uniformly over their lifetime. Common examples include:

  • Mortgages - Home loans typically amortized over 15-30 years
  • Auto loans - Vehicle financing usually with 3-7 year terms
  • Personal loans - Unsecured loans for various purposes
  • Student loans - Education financing with extended repayment options

How Loan Amortization Works

In the early stages of repayment, a larger portion of each payment goes toward interest rather than principal. As the loan balance decreases, the interest portion of each payment becomes smaller, and more of your payment goes toward reducing the principal. This calculator shows you exactly how this process unfolds over the life of your loan.

Impact of Extra Payments

Making additional payments directly toward your principal can significantly reduce both the loan term and total interest paid. Even small regular extra payments can shave months or years off your loan and save you thousands in interest charges.

Loan Terminology

Principal: The original amount borrowed
Interest Rate: The percentage charged for borrowing money
APR: Annual Percentage Rate includes both interest and fees
Term: The length of time to repay the loan in full
Amortization: The process of gradually paying off a loan through regular payments
