What Is This Tool?

The Amortization Calculator breaks a loan down payment by payment. Enter the loan amount, term in years, and interest rate, and it returns your monthly payment, the total of all payments, and the total interest. A donut chart splits principal from interest, a line chart tracks the balance falling over time, and two schedules — one annual, one monthly — show exactly how each payment divides between interest and principal. The result can be downloaded as a PDF.

How to Use This Tool?

  • Enter the loan amount.
  • Set the loan term in years and the interest rate.
  • Click Calculate to see the payment and totals.
  • Open the annual or monthly schedule, or download a PDF.

Key Features

  • Calculates the monthly payment, total payments, and total interest.
  • Shows a principal-versus-interest donut chart.
  • Charts the loan balance declining over the full term.
  • Provides both annual and month-by-month amortization schedules.
  • Offers a PDF download of the results.

Examples

  • A $160,000 loan over 10 years at 4% has a $1,619.92 monthly payment.
  • Total payments come to $194,390.67.
  • Of that, $34,390.67 is interest.
  • In year one, $13,280.79 goes to principal and $6,158.27 to interest.

Common Use Cases

  • Seeing how a loan is paid down over time.
  • Comparing total interest across different terms.
  • Checking how much of each payment is interest versus principal.
  • Planning a payoff schedule year by year.
  • Understanding the cost of a mortgage or personal loan.

Tips & Best Practices

  • Use the monthly schedule to see how early payments are mostly interest.
  • Try a shorter term to see how much interest you save.
  • Compare a lower rate to gauge its effect on total cost.
  • Check the annual schedule for a quick year-by-year overview.
  • Round figures may differ slightly from your lender's statement.

Limitations

  • Results assume a fixed rate and equal monthly payments.
  • Taxes, insurance, and fees are not included.
  • Extra or missed payments are not modeled.
  • Nothing is saved between sessions — only the current result can be exported as a PDF.

Frequently Asked Questions

What does amortization mean?
It's the process of paying off a loan through regular payments that cover both interest and principal.

Why is so much early payment interest?
Interest is charged on the outstanding balance, which is highest at the start, so early payments are mostly interest.

What's the difference between the two schedules?
The annual schedule summarizes each year, while the monthly schedule shows every individual payment.

How can I pay less interest overall?
Choosing a shorter term or a lower rate reduces the total interest paid over the life of the loan.

Principal
