What Is an Auto Loan Calculator?
An auto loan calculator helps estimate the monthly payment and total cost of financing a vehicle. You can enter the vehicle price, down payment, trade-in value, amount owed on a trade-in, interest rate, loan term, sales tax, dealer fees, registration fees, and optional extra payments.
This free car payment calculator can help you compare new car loans, used car loans, dealer financing, and vehicle loan offers. It gives an estimate of the amount financed, total interest, total vehicle cost, APR impact, and amortization schedule.
Monthly Car Payment
Estimate your monthly auto loan payment based on price, rate, term, taxes, fees, and trade-in value.
Trade-In Impact
See how trade-in equity or negative equity affects the amount financed.
Taxes and Fees
Add sales tax, dealer fees, and registration fees for a more realistic estimate.
Amortization Schedule
Review monthly principal, interest, and remaining balance across the loan term.
How Car Financing Works
Auto financing spreads the cost of a vehicle over a selected loan term. A lender charges interest based on the amount financed and the interest rate. The amount financed usually includes the vehicle price, sales tax, dealer fees, registration fees, and any negative equity, minus the down payment and trade-in value.
- Vehicle price: the purchase price of the car before taxes and fees.
- Down payment: money paid upfront to reduce the loan amount.
- Trade-in value: the value credited for your current vehicle.
- Negative equity: the amount you still owe on a trade-in if it is higher than the trade-in value.
- Loan term: the number of months used to repay the auto loan.
Auto Loan Formula
The calculator uses this standard loan payment formula and then adds optional extra monthly payments to show payoff and interest changes.
New vs Used Car Loans
New car loans may offer lower promotional rates, but new vehicles usually cost more and may depreciate quickly. Used car loans may have lower purchase prices, but rates can be higher depending on vehicle age, credit profile, lender, and market conditions. Use this calculator to compare both options before choosing.
Down Payment and Trade-In Impact
A larger down payment or positive trade-in equity can lower the amount financed. This may reduce the monthly car payment and total interest. However, if you owe more on your trade-in than it is worth, that negative equity may increase the new auto loan amount.
