How to use it
Car payment and auto loan payment estimates
This car payment calculator estimates a monthly auto loan payment based on the vehicle price, down payment, trade-in value, sales tax, fees, interest rate, and number of months financed.
Try different loan terms and down payments to see how the monthly auto payment changes. A lower monthly payment can still cost more over time if the loan term is longer or the interest rate is higher.
The amount financed starts with the vehicle price, adds estimated sales tax and fees, then subtracts your down payment and trade-in value. The monthly payment is estimated with an amortized loan formula.
Use the total interest and total paid results to compare offers. A longer loan may look easier month to month, but the total cost can be higher if the rate stays the same.
Formula
How the auto payment is calculated
The calculator first estimates the amount financed.
Amount financed = vehicle price + sales tax + fees - down payment - trade-in
Then it uses the same fixed-payment loan formula used for many installment loans. The result is an estimate, because actual dealer fees, lender terms, rebates, registration, and insurance can vary.

Payment estimate questions
Does this include sales tax?
Yes. The calculator estimates sales tax from the vehicle price and adds it to the financed amount.
Does this include insurance?
No. Auto insurance is separate from the loan payment and should be estimated separately.
Should I include dealer fees?
Yes, if you know them. Dealer fees, registration, title, and other charges can change the amount financed and the monthly payment.
Why compare total interest?
Total interest helps show the long-term cost of the loan. Two loans can have similar monthly payments but very different total costs.
