How It Works
- Enter the loan amount, interest rate, and term in years.
- Optionally add an extra monthly payment to accelerate payoff.
- The calculator uses standard amortization formulas to compute monthly breakdowns.
- View the full amortization table and balance chart to track your progress.
Understanding Loan Amortization
When you take out a mortgage or other installment loan, each monthly payment is split between interest and principal. In the early years, most of your payment goes toward interest. Over time, the balance shifts and more of each payment goes toward reducing the principal. This process is called amortization, and our calculator shows you exactly how each payment breaks down over the life of your loan.
Extra payments can have a dramatic effect on the total cost of your loan. Even adding a small amount each month goes entirely toward reducing the principal, which in turn reduces the interest charged in all future months. For example, adding just $100 per month to a $300,000 mortgage at 6.5% interest could save you over $50,000 in interest and shorten your loan term by several years.
The interest rate is the single most important factor in determining the total cost of a loan. A difference of even 0.5% on a 30-year mortgage can mean tens of thousands of dollars in additional interest over the life of the loan. Use the calculator to compare different rates and see how shopping for a better rate can save you substantial money.
Tips & Best Practices
- ✓Make biweekly payments instead of monthly. This results in 26 half-payments (13 full payments) per year instead of 12, effectively making one extra payment annually.
- ✓Apply any bonuses, tax refunds, or unexpected income as extra payments toward your principal.
- ✓Compare 15-year versus 30-year terms. Shorter terms have higher monthly payments but dramatically lower total interest costs.
- ✓If your interest rate is high, consider refinancing when rates drop by at least 0.75-1% to save significantly over the remaining term.
- ✓Always verify that your lender applies extra payments to the principal balance, not to future payments.
Frequently Asked Questions
What is an amortization schedule?
An amortization schedule is a complete table showing every monthly payment over the life of your loan, broken down into principal and interest portions. It shows how the balance decreases over time and how much total interest you will pay.
How are extra payments applied?
Extra payments go entirely toward reducing your principal balance. This means you pay less interest in every subsequent month because interest is calculated on the remaining balance. The savings compound over time, making even small extra payments very effective.
Does this work for different types of loans?
Yes, this calculator works for any fixed-rate installment loan including mortgages, auto loans, personal loans, and student loans. Simply enter the loan amount, annual interest rate, and loan term to see your amortization schedule.
Why does most of my early payment go to interest?
Interest is calculated as a percentage of the remaining balance. When the balance is highest (at the beginning of the loan), the interest portion is largest. As you pay down the principal, the interest portion shrinks and more of each payment goes toward the principal.
