What an amortization table shows you
An amortization table is a month-by-month breakdown of your loan payments. It shows you exactly how much of each payment goes toward interest, how much goes toward the principal (the amount you borrowed), and what you still owe after each payment. Most lenders provide this table when you sign your loan documents, and you can also ask for one at any time during the loan term.
The table answers a question many borrowers have: if I'm paying $400 a month, why does my balance barely go down at the start? The answer is in the amortization table. Early payments are weighted heavily toward interest, so your principal balance drops slowly at first, then faster as you move through the loan.
Key Takeaways
- An amortization table lists every payment you will make, breaking down how much goes to interest versus principal each month.
- Early payments contain more interest and less principal; later payments flip that ratio as your balance shrinks.
- You can use the table to see what you owe at any point, or to understand the cost of paying off the loan early.
- Your lender must provide this table, and you can request an updated one if you make extra payments or refinance.
- The total interest you pay depends on the loan amount, interest rate, and how many months you have to repay it.
The columns in a standard amortization table
Every amortization table has the same basic structure. The first column is the payment number (1, 2, 3, and so on through the final payment). The second column is the payment date or the month. The third column is the payment amount — this stays the same every month for a standard auto loan.
The fourth column is the interest portion of that payment. This is money that goes to your lender as the cost of borrowing. The fifth column is the principal portion — the amount that actually reduces what you owe. The sixth column is the remaining balance, also called the loan balance. This is what you would owe if you paid off the loan completely after that payment.
Some lenders add extra columns for cumulative interest paid to date, or cumulative principal paid to date. These are helpful if you want to see at a glance how much interest you have paid over the first year, for example.
Why the interest portion shrinks over time
Interest is calculated on the balance you owe right now, not on the original loan amount. So when you owe $25,000, the monthly interest is higher than when you owe $15,000. As your balance drops, the interest portion of your payment drops too, and the principal portion grows.
This is why a 60-month loan has much more total interest than a 36-month loan at the same rate. You are paying interest for more months, and your balance stays higher for longer. If you borrowed $20,000 at 6% for 36 months, you might pay roughly $1,900 in total interest. The same loan over 60 months might cost roughly $3,200 in total interest — the extra 24 months of payments means 24 extra months of interest charges.
How to find your current loan balance using the table
If you want to know what you owe right now, find the row for your most recent payment in the amortization table. The remaining balance column on that row is your current loan balance. This is the amount you would need to pay to close out the loan completely.
If you have made extra payments or paid ahead, your actual balance may be lower than what the table shows. In that case, contact your lender for an updated statement. Many lenders also show your current balance on your monthly statement or online account.
Using the table to understand early payoff
One of the most useful things an amortization table shows is what happens if you pay off the loan early. Find the row for the month you plan to pay it off, and the remaining balance column tells you exactly what you owe on that date.
For example, if you want to pay off your loan after 36 payments instead of 60, the table shows you the balance at month 36. That is the amount you would need to pay, plus any interest accrued since your last payment. By paying early, you avoid all the interest charges in the remaining 24 months — which can be hundreds or even thousands of dollars depending on your loan size and rate.
Some lenders charge a prepayment penalty for paying off early, though this is less common with auto loans than with mortgages. Check your loan documents to see if yours does. If there is no penalty, the amortization table makes it straightforward to see exactly how much you save by paying ahead.
Getting an amortization table from your lender
Your lender should have provided a full amortization table when you signed your loan. It may have been in a packet of documents, or sent to you by email. If you cannot find it, call or log into your lender's website and request one. Most lenders can email or mail it to you within a few business days at no cost.
If you have made extra payments or refinanced your loan, ask for an updated amortization table that reflects your current balance and remaining payment schedule. This is especially useful if you want to see how much time and interest you have saved by paying ahead.
Common reasons to review your amortization table
Many borrowers look at their amortization table when they are thinking about paying off the loan early, or when they want to understand why their balance is not dropping as fast as they expected. It is also helpful when you are budgeting — the table shows you exactly what your payment will be every month, with no surprises.
If you are considering refinancing your auto loan, comparing the amortization tables from your current loan and a new loan offer shows you the real difference in total interest cost. A lower rate might save you hundreds of dollars over the life of the loan, and the table makes that visible.
Frequently Asked Questions
Why does my first payment have so much interest and so little principal?
Interest is calculated on the full balance you owe at the start of the loan. As you pay down the principal, the interest portion shrinks because it is calculated on a smaller balance each month. This is normal and happens with every auto loan.
Can I use an amortization table to see what I owe right now?
Yes, but only if you have not made any extra payments. Find your most recent payment in the table and look at the remaining balance column. If you have paid ahead, contact your lender for an updated balance because the table will not reflect those extra payments.
What if I want to pay off my loan in 48 months instead of 60?
Find the row for month 48 in your amortization table. The remaining balance on that row is what you would owe if you paid off the loan then. You would avoid all the interest charges from months 49 through 60. Check your loan documents to confirm there is no prepayment penalty.
Does the amortization table change if I refinance?
Yes. When you refinance, you get a new loan with a new rate, new term, and a new amortization table. The new table starts from your current balance and shows the payment schedule for the new loan. Your old table is no longer relevant.
Where can I find an amortization table if my lender did not give me one?
Contact your lender directly and request one — they are required to provide it. You can also use an online auto loan calculator to create one if you know your loan amount, interest rate, and term, though the lender's official table is more reliable.
