Understanding mortgage amortization

Mortgage amortization is the process of repaying a loan with regular payments that include both principal (the amount you borrowed) and interest (the cost of borrowing). Early in the term, a larger share of each payment goes to interest; over time, more goes toward principal, accelerating your payoff.

For students, this model is a practical example of exponential math in finance. For professionals and homebuyers, it’s a decision tool: you can compare interest rates, terms, and optional extra payments to see how each factor changes the total interest and the payoff time.

Key concepts at a glance

  • Principal: The original loan amount you still owe.
  • Interest: The lender’s charge, typically expressed as an annual percentage rate.
  • Term: The length of time to repay your loan (e.g., 15 or 30 years).
  • Monthly payment: A fixed amount that covers interest and repays principal.
  • Extra payments: Additional amounts applied to principal to reduce interest and shorten the term.

Why extra payments matter

Even small extra payments can dramatically reduce total interest and shave years off your mortgage. This happens because the principal declines faster, so future interest (calculated on a lower balance) is smaller. Our calculator lets you test different scenarios instantly.

Tip: If your loan has prepayment rules, check whether there are fees or limits before making extra payments.

Global compatibility

This tool is currency-agnostic and supports any country. Enter your currency amounts without symbols and use a decimal annual interest rate. The schedule assumes fixed-rate, fully amortizing loans with monthly payments.

Frequently asked questions

HOW TO calculate mortgage amortization with this tool?
Enter your loan amount, annual interest rate, and term in years, optionally add a monthly extra payment, then click Calculate to see your monthly payment, total interest, and full amortization schedule. The 3D doughnut chart visualizes principal vs. interest as percentages.
HOW TO read the amortization table?
Each row represents a month. Columns show total payment, how much goes to principal and interest, extra payment applied, cumulative total paid, and the remaining balance. As time passes, the principal portion grows while interest declines.
HOW TO reduce total interest paid?
Consider a shorter term, make extra principal payments, or refinance to a lower rate if available. Test each option in the calculator to see the impact on interest and payoff time before committing.
HOW TO use different currencies or countries?
Enter amounts in your local currency (no symbols). The math is the same worldwide for fixed-rate, monthly-amortized loans. Local taxes, insurance, or fees vary by country and are not included by default.
HOW TO include taxes or insurance?
This tool focuses on loan amortization. To approximate an all-in payment, add your monthly escrow (taxes/insurance) to the monthly payment shown. For exact values, consult your lender or local tax authority.
