Compare the remaining loan with one new offer
Start with your outstanding principal, current annual rate, and remaining term of 1 to 120 months. The current side estimates the payments and total spending still ahead from today; it does not recreate payments already made or infer a payoff amount from an original loan.
On the refinance side, enter the proposed nominal annual rate and new term. Comparing both schedules helps separate a smaller monthly payment from a lower remaining cost. The official CFPB auto-loan tools encourage borrowers to compare loan terms, not only a payment.
Choose how refinance fees are treated
Enter refinance fees once, then mark them as paid upfront or financed. Paid-upfront fees are added outside the new loan balance. Financed fees are added to the principal before the payment is calculated, so they can also accrue interest over the new term.
The tool reports total remaining spending for each path and the monthly payment difference. A longer new term may lower the monthly estimate while increasing total interest or total spending. It is a trade-off to inspect, not proof that refinancing is better.
What the fee-recovery figure means
When fees are paid upfront and the refinance reduces the monthly payment, the tool can show a simple recovery time: upfront fees divided by monthly reduction. It only shows that arithmetic within the months both schedules overlap.
That figure is not an economic break-even calculation. It does not value time, account for selling or paying off the vehicle early, or establish savings. Financed fees are not used in that recovery figure because they add interest rather than being paid once upfront.
Keep payoff and lender rules separate
This refinancing an auto loan calculator uses monthly amortization and nominal annual interest, not APR. It keeps full calculation precision but displays currency to two decimals. A lender may use a daily-interest payoff, different timing, credits, taxes, or other rules.
Check a current payoff amount, the proposed disclosures, any fees, and the complete new term before acting. A comparison can help frame questions, but only the lender can state eligibility, final rate, payment, and closing requirements.
Auto Loan Refinance Calculator FAQs
What does a refinancing an auto loan calculator compare?
It compares estimated payments and remaining spending on your current outstanding balance with one new loan rate, term, and fee treatment.
Is this also a vehicle loan refinance calculator?
Yes. Vehicle loan refinance calculator is another clear description of this single auto-loan comparison page; it does not create a separate calculation or quote.
Why can a lower payment cost more overall?
A longer refinance term can spread principal over more months. That may reduce the monthly payment while allowing more interest to accumulate.
What happens when I finance the fees?
Financed fees are added once to the new principal. They increase the calculated payment base and can accrue interest throughout the selected refinance term.
Is fee recovery a break-even calculation?
No. It is only upfront fees divided by monthly payment reduction, limited to overlapping months. It excludes time value, early payoff, and other costs.
Are the rates APRs or loan offers?
Neither. Enter nominal annual rate assumptions for an educational estimate. APR and final loan terms are lender disclosures and may include fees or different rules.
Sources and model assumptions
These tools estimate payments; they do not offer credit, check eligibility or recommend a lender. Default numbers are illustrative. The underlying monthly amortisation formula uses a nominal annual interest rate divided by twelve, not a fee-inclusive APR. Our calculation documentation was prepared on 26 October 2026; this is not a claim of independent professional review.
The scenario holds rates fixed, uses equal monthly periods and retains unrounded values until display. It excludes unentered fees, missed/extra payments, variable-rate paths and contractual balloons. Confirm the actual agreement and payoff quote before making a borrowing decision.
