Car Loan Payoff Calculator

How this car loan payoff calculator works

The engine is the same month-by-month amortization simulation used on the loan payoff calculator: each month, interest accrues on your remaining balance at your APR divided by 12, your payment covers that interest first, and the rest reduces principal. Add an extra monthly payment or a one-time extra payment and the calculator shows exactly how much time and interest those extra dollars save, compared to a baseline run with no extra payments at all.

Car loans tend to be shorter and carry higher rates than mortgages, typically 3-7 years at anywhere from 4% to well over 20% APR depending on credit and whether the loan is new, used, or from a buy-here-pay-here lender. That shorter term means extra payments have less time to compound than on a 30-year mortgage, but a higher rate means each extra dollar still removes a meaningful chunk of future interest, worth checking with your own numbers.

A worked example

A $24,000 auto loan at 7.9% APR with a $460/month payment pays off in 5 years 5 months and costs about $5,500 in total interest. Adding just $75 extra each month cuts about 11 months off that payoff time and saves close to $1,000 in interest, without a huge change to the monthly budget. Try your own balance, rate and payment in the calculator above to see the equivalent for your loan.

Should you pay off a car loan early?

It depends mostly on your interest rate and what else you would do with the money. A car loan above roughly 7-8% APR is usually worth paying down faster if you do not have higher-interest debt (credit cards especially, see the debt payoff calculator for that comparison) and you already have an emergency fund in place. A very low-rate loan, sometimes available on new-car promotional financing, is less urgent to pay off early, the same money might do more sitting in savings or going toward higher-rate debt first. There is also no prepayment penalty on the vast majority of auto loans in the US, worth a quick check of your loan agreement, but it is rare, so extra payments are usually free money saved with no downside.

Trade-in and payoff timing

If you are planning to trade in or sell the vehicle before the loan is paid off, your payoff date and total interest here only tell part of the story, you will also need your exact payoff amount from your lender (not just this calculator's estimate) at the time of the trade, since a car loan payoff quote includes exact per-day interest accrual your lender calculates directly. Use this calculator to plan ahead and see whether extra payments before a planned trade-in would meaningfully reduce what you owe at that point, then confirm the exact number with your lender close to the actual trade date.

RV and other vehicle loans

RV loans work the same way mathematically, fixed balance, fixed rate, regular payment, just often with a longer term (10-20 years is common for larger RVs) and sometimes a higher rate than a typical car loan. The same extra-payment math applies: a recurring or one-time extra payment reduces the balance that future interest accrues on, for the rest of the loan. Enter your RV loan's actual balance, rate and payment above the same way you would for a car loan, the calculator does not need to know what type of vehicle it is, just the loan numbers themselves.
