Auto Loan Calculator

Plan your car purchase with monthly payment estimates.

What You'll Get From This Auto Loan Calculator

Use this Auto Loan Calculator to estimate how much you may need to finance when buying a new or used vehicle. It takes into account the vehicle price, down payment, trade-in value, cash incentives, interest rate, loan term, sales tax, and other purchase fees to estimate the amount financed and your monthly car payment.

This can help you compare different car-buying scenarios before you make a purchase. For example, you can see how a larger down payment, a higher trade-in value, a different loan term, or financing taxes and fees can change your monthly payment and the overall cost of the vehicle loan.

Start with the complete vehicle purchase

An auto-loan estimate is more informative when it reflects the full transaction rather than only the sticker price. Enter the vehicle price, then account for your down payment and any trade-in value. If the calculator provides fields for incentives, sales tax, dealer or purchase fees, or other charges, include the amounts that apply to your scenario. These details help distinguish the vehicle's advertised price from the amount that may actually need to be financed.

Compare financing choices carefully

The interest rate and loan term can change the monthly payment and the total amount paid for the financing. A longer term may spread the balance over more payments, while a shorter term may require a larger scheduled payment. When comparing offers, keep the vehicle price and upfront contribution consistent first, then change one financing variable at a time so you can see what is responsible for the difference in the result.

Look beyond the monthly car payment

A payment that fits a monthly budget does not necessarily describe the complete cost of owning the vehicle. Use the calculator to understand the financed amount, interest cost, and repayment total, then consider separate ownership expenses such as insurance, fuel, maintenance, registration, and other recurring costs. Before signing a purchase or financing agreement, verify the final price, taxes, fees, rate, term, and lender charges against the actual documents because the calculator does not replace a dealer or lender quote.

Separate financing from ownership costs

The financing estimate covers the loan scenario, not every expense associated with owning a vehicle. Registration, insurance, fuel, maintenance, warranties, and other ownership costs may need to be budgeted separately. Keeping those costs separate makes it easier to compare financing scenarios without confusing the cost of borrowing with the ongoing cost of the vehicle.

About Auto Loan Calculator

An auto loan is a type of installment financing used to purchase a new or used vehicle. The amount you repay depends on more than the vehicle's advertised price. Your down payment, trade-in value, cash incentives, interest rate, loan term, sales tax, and vehicle-related fees can all affect the amount financed and the total cost of the loan.

This Auto Loan Calculator estimates your monthly car payment and the overall cost of financing based on the information you enter. It accounts for cash incentives, a down payment, the value of a trade-in, any remaining balance on the trade-in, sales tax, and additional vehicle fees. You can also choose whether taxes and fees are included in the loan or paid upfront.

How Auto Loan Payments Are Calculated

For a standard fixed-rate auto loan, the monthly payment is calculated from the amount financed, monthly interest rate, and number of monthly payments.

Monthly Payment = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)

In this formula, P is the amount financed, r is the monthly interest rate, and n is the total number of monthly payments. The amount financed may include the vehicle price after incentives and trade-in adjustments, along with taxes and fees when those costs are financed.

Factors That Affect Your Auto Loan

A larger down payment generally reduces the amount you need to borrow. A higher trade-in value can also reduce the amount financed, while any remaining loan balance on the trade-in increases the amount that may need to be financed. A longer loan term can reduce the monthly payment but usually increases the total interest paid over the life of the loan.

Sales taxes, registration costs, title fees, documentation charges, and other purchase costs can also increase the total amount required to buy a vehicle. If these costs are financed rather than paid upfront, they also become part of the balance on which interest is charged.

Understanding the Results

The calculator shows the estimated monthly payment, amount financed, total loan payments, total interest, upfront payment, and total vehicle cost. The amortization schedule shows how each payment is divided between interest and principal and how the remaining balance decreases over time.

Actual auto loan terms vary by lender, credit profile, vehicle type, taxes, fees, and the final purchase agreement. This calculator provides an estimate and should be used to compare financing scenarios before making a vehicle purchase.
