About this car loan calculator
Auto loans are amortizing installment loans, just like mortgages, but on a much shorter timeline — typically 2 to 7 years instead of 15 or 30. This calculator takes your vehicle price, subtracts your down payment (and trade-in value, if you fold that into the down payment figure), and spreads the remaining loan amount across equal monthly payments using the same amortization math lenders use to price auto financing.
Because car loan terms are short, the term length you choose has a big effect on affordability versus total cost. A 3-year loan carries a higher monthly payment but far less total interest, since the balance is paid off quickly. Stretching to a 6- or 7-year term lowers the monthly payment enough to fit more expensive vehicles into a budget, but it also means paying interest for years longer — and it raises the risk of being "underwater," owing more than the car is worth, since vehicles depreciate faster than a long loan pays down principal.
Your down payment does double duty on a car loan: it reduces the amount you finance (and therefore your monthly payment and total interest), and it protects you against rapid depreciation in the loan's early months, when a new vehicle can lose a meaningful share of its value in the first year alone. Trading in a vehicle with positive equity effectively works the same way, reducing the amount financed on the new loan.
Auto loan interest rates depend heavily on whether the vehicle is new or used, your credit score, and the lender — dealership financing, banks, credit unions, and manufacturer captive lenders (offering promotional rates on new cars) can all quote noticeably different rates for the same borrower. Credit unions in particular are often competitive on used-car rates compared to dealership financing.
This calculator is an estimate for informational purposes only. It shows principal and interest based on the numbers you enter, but it doesn't include sales tax, title and registration fees, dealer add-ons, or extended warranties, all of which are commonly rolled into an actual auto loan and increase the amount financed. Your real rate and approved terms depend on your credit profile and the specific lender, so use this tool to compare scenarios before you visit a dealership or apply for financing.

Car loan calculator questions
How auto loan payments and amortization work.
How is my car loan payment calculated?
This calculator subtracts your down payment from the vehicle price to get your loan amount, then applies the standard amortization formula to spread that amount across equal monthly payments over your loan term, based on your interest rate.
Does this include sales tax and fees?
No. This calculator shows principal and interest only, based on the vehicle price and down payment you enter. Real auto loans commonly roll in sales tax, title, registration, and dealer fees, which increase the amount actually financed.
Should I choose a shorter or longer car loan term?
A shorter term (2-4 years) means a higher monthly payment but much less total interest and faster equity in the vehicle. A longer term (6-7 years) lowers the monthly payment but increases total interest and raises the risk of owing more than the car is worth as it depreciates.
How much should I put down on a car?
There's no fixed rule, but a common guideline is at least 10-20% down on a new car to offset the rapid depreciation that happens in the first year. A larger down payment also lowers your monthly payment and total interest directly.
Does a trade-in work the same as a down payment?
Yes, functionally. If your trade-in has positive equity (it's worth more than you owe on it), that value reduces the amount you need to finance on the new loan, just like cash down. You can enter your trade-in equity in the down payment field to model this.
Why do new and used cars often have different interest rates?
Lenders generally see used cars as higher risk, partly because of uncertain condition and faster ongoing depreciation, so used-car loan rates are often a percentage point or more higher than new-car rates for the same borrower.
Is dealership financing or a credit union loan better?
It depends on the offer. Dealerships sometimes offer promotional low rates from the manufacturer on new cars, while credit unions and banks are often more competitive on used-car loans. Getting pre-approved by a bank or credit union before visiting a dealership gives you a rate to compare against.
Is this calculator's payment exactly what I'll be approved for?
No — it's an estimate for informational purposes only. Actual approval, rate, and term depend on your credit profile, income, and the specific lender. Use this tool to compare scenarios, then confirm exact numbers with a real loan offer.
