What an amortization table shows you
An amortization table is a month-by-month breakdown of your car loan. It shows you exactly how much of each payment goes toward interest and how much goes toward the principal (the amount you borrowed). Most importantly, it shows your remaining balance after each payment, so you can see when the loan ends and how much you will have paid in total.
Your lender should provide this table when you sign the loan documents, or you can request it at any time. If you have the loan amount, interest rate, and loan term, you can also generate one online using a free amortization calculator. The table itself does not change your loan — it straightforward makes visible what is already in your contract.
Key Takeaways
- Each row in an amortization table shows your payment amount, how much goes to interest versus principal, and what you still owe after that payment.
- Early payments are mostly interest; later payments are mostly principal, even though your total payment stays the same.
- You can use the table to see exactly when you will own the car free and clear, and what happens to your balance if you pay extra.
- The total interest you pay over the life of the loan appears at the bottom of the table and depends on your interest rate and how long you borrow.
How the columns in an amortization table work
A standard amortization table has five columns: payment number (or date), payment amount, principal paid, interest paid, and remaining balance. The payment amount stays the same every month — that is the fixed payment you agreed to. But the split between principal and interest changes every single month.
The interest paid column shows how much of that month's payment goes to your lender as interest. The principal paid column shows how much actually reduces what you owe. Add those two together and you get your total payment. The remaining balance column shows what you still owe after that payment is made.
Here is a simplified example of what the first three rows might look like on a $20,000 loan at 6% interest over 60 months:
| Payment # | Payment Amount | Principal Paid | Interest Paid | Remaining Balance |
|---|---|---|---|---|
| 1 | $386.66 | $286.66 | $100.00 | $19,713.34 |
| 2 | $386.66 | $288.09 | $98.57 | $19,425.25 |
| 3 | $386.66 | $289.52 | $97.14 | $19,135.73 |
Notice that your payment stays at $386.66, but the interest portion shrinks slightly each month while the principal portion grows. This pattern continues throughout the entire loan.
Why you pay more interest at the beginning
Interest is calculated on whatever balance you still owe. At the start of your loan, you owe the full amount, so the interest charge is largest. As you pay down the principal, the balance shrinks, and so does the interest charge on the next payment.
This is why the first payment might be 70% interest and 30% principal, but by payment 50, it might be 10% interest and 90% principal. Your lender is not changing the deal — the math of how interest works just means you pay most of it early. This is true for every loan: mortgages, personal loans, and car loans all follow this pattern.
If you want to own the car faster and pay less total interest, you can make extra payments toward principal. The amortization table shows you what your balance would be under the original schedule, but any extra payment you make reduces that balance when ready and saves you interest on all future payments.
Reading the total interest and loan cost
At the bottom of a full amortization table, you will see the total amount of interest you will pay over the life of the loan. In the example above, a $20,000 loan at 6% over 60 months would cost roughly $3,200 in total interest, meaning you pay back about $23,200 altogether.
This total depends on three things: how much you borrow, what interest rate you receive, and how long the loan lasts. A higher rate or longer term means more total interest. A lower rate or shorter term means less. You can use different amortization tables to compare scenarios — for instance, what if you borrowed $18,000 instead, or took a 48-month loan instead of 60 months.
Many people focus only on the monthly payment, but the amortization table shows you the real cost of the loan. That $386.66 payment sounds reasonable until you see that you are paying $3,200 in interest alone.
Using an amortization table to plan early payoff
If you want to pay off your car loan early, the amortization table helps you see the payoff. Look at the remaining balance column and find the row where you plan to make your final payment. That is how much you would owe at that point under the original schedule.
For example, if you want to pay off the loan after 48 payments instead of 60, the table shows you exactly what balance remains at month 48. You would pay that amount as your final payment, and you would own the car free and clear. The interest you save by skipping those last 12 payments appears in the table as the interest you no longer owe.
Before you make extra payments, check your loan documents for prepayment penalties. Most car loans do not have them, but some do. If there is no penalty, paying extra toward principal is one of the fastest ways to reduce the total cost of your loan.
Where to get your amortization table
Your lender is required to provide an amortization schedule as part of your loan documents. If you received a thick packet when you signed, the table is likely in there. If you cannot find it, call your lender's customer service line or log into your online account — most lenders post it there.
If you do not have your loan documents or want to see what different loan scenarios would cost, you can generate a free amortization table using an online calculator. You will need your loan amount, interest rate, and loan term in months. Bankrate, NerdWallet, and many other financial websites offer these calculators at no cost.
Frequently Asked Questions
Can I use an amortization table to see what happens if I pay extra each month?
The standard table shows the original schedule, but you can create a new one using a calculator if you input a shorter loan term. For example, if you plan to pay an extra $50 per month, you could generate a table for a 48-month loan instead of 60 to see roughly what that looks like. The exact numbers depend on how your lender applies extra payments, so confirm with them first.
Why does my remaining balance not match what my lender says I owe?
The amortization table shows your balance as of a specific date, usually right after a payment posts. If you check your balance mid-month or before a payment has been processed, the numbers will not match. Also, if you have made extra payments or skipped a payment, your actual balance will differ from the table. Call your lender to confirm your current balance.
Does the amortization table change if interest rates go up?
No. Your amortization table is locked in based on the interest rate in your loan contract. If market rates rise, your table does not change. However, if you refinance your loan (take out a new loan to pay off the old one), you would get a new amortization table based on the new rate and term.
What if I want to see the amortization table before I sign the loan?
Ask the dealer or lender to show you the table as part of the loan offer. They should be able to generate one based on the loan amount, rate, and term they are proposing. This lets you see the total cost and monthly payment before you commit, which is a smart step in any car purchase.
