Loan amortization is a process that splits your monthly payment between paying interest and paying off the principal balance of your loan. Your outstanding balance decreases with each payment, and the percentage of each payment that goes toward paying interest gradually increases.
Amortizing loans include mortgages, auto, personal, and student loans. Understanding how these loans work can help you make smarter decisions about debt management.
Interest Rate
Loan amortization allows borrowers to pay off their debt by spreading out a portion of each payment towards the principal balance and interest costs on the outstanding loan amount. This helps them manage and track their expenses, which are usually deducted for tax purposes. Loan amortization is often used for mortgages, personal and auto loans, and other long-term debt instruments like student loans and home equity lines of credit (HELOC).
The percentage of each payment that goes toward both the principal and interest on an amortizing loan will change throughout the repayment term. Initially, more of each payment will cover interest charges because the loan balance is higher. As the loan nears its end, a larger share of each payment will be applied to principal because the balance is lower.
Using an amortization calculator can help you understand how much each payment will cost you and how it will change over time. It can also help you calculate the maximum principal remaining on a loan when it is fully paid off, which may be useful information for anyone seeking a loan or looking to buy a home.

Payments
If you take out an amortizing loan, such as a mortgage, auto, or personal loan, your monthly payments will go toward the principal and interest. The bulk of your payment will be applied to paying off the interest initially, but as you move through your loan term, more and more of your payment will be used to reduce your principal balance.
This repayment model is popular among borrowers and lenders because it offers predictability for both parties. Knowing how much your monthly payments will help you plan for future expenses and reduce the likelihood of defaulting on your loan.
Your loan payments will be divided into two categories—interest and principal—each calculated using a formula that uses the loan amount, term, and interest rate. A loan amortization schedule will break down your payments over time, showing how the portion of your payment that goes toward interest will decrease as you make payments and how the outstanding principal balance will also reduce.
You may also see a column for “extra payments,” which refers to any payments made above the minimum payments required by your loan’s terms. Adding extra costs to your regular loan repayments will typically speed up the process of paying off your principal and help you save on total interest paid over the life of your loan.
Payment Schedule
A loan amortization schedule shows how your payments chip away at the principal and interest on your debt over time. An amortized loan typically has fixed monthly payments that are applied to both the principal and interest of the loan. At the beginning of the loan term, more of each payment is generally applied toward interest than principal. Over the life of the loan, however, more of each payment goes toward paying down principal and less toward interest until the end of the repayment term, when the remaining balance is $0.
An amortized loan is a good choice for consumers who need a predictable debt instrument. With this type of loan, you can easily determine the monthly payment amount and how much of it will go toward principal versus interest, even before you take out the financing. Loan amortization is often used for mortgages, student loans, and auto loans.
To calculate the monthly payment amount, start with the current outstanding balance on the debt and subtract the annual interest rate from it. Then divide the result by the number of months in the payment period to find the payment amount. Alternatively, you can use an online calculator or a loan amortization spreadsheet. Once you calculate your payment, you can create a loan amortization schedule and use it to plan your debt payments.
Amortization Schedule
A loan amortization schedule is a table that illustrates how your monthly loan payment contributes to both the principal and interest over time. This allows borrowers to see the percentage of each payment used to pay interest and the specific amount paid towards principal. Typically, early on in the life of an amortized loan, more of each payment is used to cover interest charges. Still, as the loan nears its end, a higher percentage of each monthly payment goes toward principal repayment.
Loan amortization is a valuable tool for both borrowers and lenders. It allows borrowers to understand how much their monthly loan payment is applied towards interest and principal. It gives lenders a clear picture of the borrower’s ability to repay the debt over the loan’s term.m
By understanding how loan amortization works, borrowers can feel more confident and empowered to make wise financial decisions regarding their mortgage or other large loans. A borrower can use the information from a loan amortization schedule to compare borrowing options and determine the best fit for their needs. Having this knowledge can also help them calculate how much money they could save by making extra payments on their mortgage and allow them to predict the impact of a refinance.
