How extra payments shorten a car loan
Each car payment first covers the interest that built up since your last payment. Whatever is left reduces the balance you owe. An extra payment goes straight to the balance, so next month's interest is figured on a smaller amount. That small difference repeats every month, which is why even modest extra payments cut the loan by months.
How this calculator works
It finds the regular payment your remaining months imply, adds your extra amount, and then runs the loan one month at a time until the balance reaches zero. The final payment is usually smaller than the rest. The savings figure compares the interest you would pay with and without the extra payments.
Before you pay extra
- Ask your lender whether extra payments are applied to the principal. Some lenders hold the money toward your next payment unless you say otherwise.
- Check your loan agreement for a prepayment penalty. They are uncommon on car loans, but confirm.
- Compare your car loan rate to your other debts. Paying extra on the highest-rate debt first saves the most.
- Keep an emergency fund. Extra money sent to the lender is hard to get back.
Frequently asked questions
Is it worth paying extra on a car loan?
It depends on your rate. The higher the APR, the more each extra dollar saves. If you have a higher-rate debt, such as a credit card, paying that down first usually saves more. If your car loan rate is high, you might also look at the refinance calculator.
Is it better to pay extra each month or a lump sum?
Both reduce interest. The sooner extra money reaches the balance, the more interest it saves, so a lump sum now saves more than the same amount spread over the next year.
Will my lender let me pay extra?
Most do. Confirm there is no prepayment penalty and ask how to mark the extra amount as a principal-only payment.
Does paying off a car loan early affect my credit?
Closing any account can change your credit mix and the average age of your accounts, so you may see a small, temporary change. Lenders report the loan as paid in full.
