How to Use this Car Loan Calculator

Inputs Description
Annual interest rate Prospective lenders will give you an interest rate quote based on factors such as your credit score, debt-to-income ratio, loan amount, length of term and the age of the vehicle you want to buy. Enter in the rate you were quoted.
Car price Enter the cost of the car you want to buy. This can be the Manufacturer's Suggested Retail Price (MSRP) or the cost you negotiated with the dealer.
Down payment This is the initial upfront portion of the total amount due and is usually paid in cash. Some experts argue buyers should put at least 20 percent down for a car, but a 2015 Edmunds analysis showed the average down payment was around 10 percent. Realistically, there isn't a magical amount that's right or wrong. Instead, you should pay an amount that won't put you in the hole or cause you to default on your loan.
First payment month This is the date you agreed to start making payments towards the loan. The date will be used to create a monthly breakdown of your payments - also called an amortization schedule - over the lifetime of the loan.
Length of term Lenders will give you a term anywhere from 12 to 84 months. However, the longer you finance your car, the more interest you pay.
Trade-in value Enter the amount of credit a car dealer is willing to give you for your current vehicle. The credit, which is based on market price, can go towards the purchase price of the new or used car you want to buy next. To do your own research on car valuation, try industry resources such as Kelley Blue Book.
Outputs Description
Balance payoff timeline A visual timeline illustrating how your total balance changes over time, if you're making the monthly payments on schedule.
Interest and principal timeline A visual timeline showing how your interest payments change over time, if you're making the monthly payments on schedule. With car loans, your payment will be applied to the interest due first. As a result, the payments at the beginning of your loan will cover more interest charge than the payments towards the end of the loan.
Monthly payments The amount you need to pay each month in order to pay off your car loan within the agreed upon length of term.
Principal paid The original amount you agreed to pay back.
Remaining balance The amount you still owe on the loan.
Total interest paid The total amount of interest you paid.
