What is the Amortization Calculator?
An amortization schedule lists every loan payment and splits it into interest and principal. Early payments are mostly interest; over time more of each payment reduces the balance.
What an amortization schedule shows
Amortization means paying off a loan in scheduled installments that cover both interest and principal. A schedule lists every payment with the part that went to interest, the part that reduced the balance, and the balance that remains. The totals at the bottom show the full cost of borrowing.
The payment stays the same on a fixed-rate loan, but the split changes every month. Interest is calculated on the current balance, so the first payments are mostly interest and the last ones are mostly principal.
Reading the yearly and monthly views
The yearly summary is the quickest way to see how fast the balance falls. The month-by-month view is better when you want to know the exact balance on a given date, for example before a planned sale or refinance.
Add an extra monthly, yearly or one-time payment to see the new payoff date. Every extra dollar goes straight to principal, which reduces the interest charged in all later months. For a mortgage with taxes and insurance included, use the mortgage calculator; for a plain installment loan, the loan calculator works the same way.
When an amortization schedule is useful
Use a schedule when you want to compare a short and a long term, plan extra payments, or find out how much principal you will have repaid by a certain year. It is also handy for understanding why paying off a loan in the first few years barely changes the balance. If you are weighing a prepayment plan, continue with the mortgage payoff calculator.
How to use the Amortization Calculator
- Fill in the fields. You will need Loan amount ($), Interest rate (% per year), Loan term: years. Use figures from a lender quote or your tax bill where you have them, and keep the term and rate realistic. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Monthly payment, and the cards below show Total interest, Total of all payments, Time to pay off. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Amortization Calculator using the default values shown in the calculator above:
Inputs
| Loan amount ($) | 300,000 |
|---|---|
| Interest rate (% per year) | 6.5 |
| Loan term: years | 30 |
Results
| Monthly payment | $1,896.20 |
|---|---|
| Total interest | $382,633.47 |
| Total of all payments | $682,633.47 |
| Time to pay off | 30 yrs |
With these inputs the calculator returns Monthly payment: $1,896.20. Change any value in the calculator to see how the result moves.
What the results tell you
The results panel of the Amortization Calculator reports Monthly payment, total interest, total of all payments and time to pay off. Compare these figures while changing one input at a time, and use the related calculators below to look at the same situation from another angle.

Frequently asked questions
What is amortization?
It is the repayment of a loan through fixed payments, where early payments are mostly interest and later ones mostly principal.
Why is so much of my first payment interest?
Interest is charged on the full balance, which is largest at the start, so interest takes the biggest share of early payments.
What is included in a monthly mortgage payment?
Principal and interest, plus property tax, homeowners insurance, PMI if your down payment is under 20%, and HOA fees if they apply.
How much house can I afford?
A common rule is to keep housing costs under about 28% of gross income and total debt under 36%. The House Affordability Calculator applies those limits to your numbers.
Are the results guaranteed?
