Auto Loan Calculator
Calculate your monthly car payment and total loan cost before you visit the dealership.
What Is an Auto Loan Calculator?
An auto loan calculator estimates your monthly car payment based on the vehicle price, down payment, interest rate, and loan term. Knowing your payment before you negotiate puts you in a stronger position at the dealership and prevents you from overextending your budget on a depreciating asset.
How to Use This Calculator
Enter the Vehicle Price
Input the total purchase price including any dealer fees, sales tax, or add-ons you expect to finance.
Set Your Down Payment
Enter the cash amount you will put down. A larger down payment reduces the financed amount and may qualify you for a better rate.
Input the Interest Rate
Enter the APR from your pre-approval or dealer offer. Get pre-approved through your bank or credit union before visiting the dealer for leverage.
Choose the Loan Term
Select your repayment period. Shorter terms cost less in interest but have higher payments. Avoid terms longer than 60 months to prevent being underwater on the loan.
Key Concepts
Depreciation
New cars lose 15-25% of their value in the first year. Longer loan terms increase the risk of owing more than the car is worth (being "underwater" or "upside-down").
Total Cost of Ownership
Beyond the loan, budget for insurance, fuel, maintenance, and registration. Total annual ownership costs average $10,000-$12,000.
Pre-Approval Advantage
Getting pre-approved from a bank or credit union before shopping gives you a rate ceiling. The dealer can try to beat it, but you have a guaranteed fallback.
The 20/4/10 Rule
20% down, 4-year term max, and total transportation costs under 10% of gross income. This framework prevents overextending on a vehicle purchase.
Expert Insights
A 0% APR deal from the manufacturer is not always the best deal. Often you must choose between 0% financing and a cash rebate. Run the numbers both ways using this calculator.
Credit union auto loans consistently offer rates 1-2% lower than dealerships. Even after you finance through the dealer, you may be able to refinance to a credit union rate within 60-90 days.
Never focus solely on the monthly payment. Dealers can make any payment seem affordable by stretching the term. Focus on total cost and interest paid.
