Frequently asked questions

How do you calculate a car down payment?

Multiply the vehicle price by the down payment percentage. For example, a 20% down payment on a $35,000 car is $7,000.

Does a larger down payment lower my car payment?

Yes. A larger down payment reduces the amount financed, which usually lowers the monthly payment and total interest.

Does trade-in value count as a down payment?

Positive trade-in equity can reduce the amount financed, similar to a down payment. If you owe more than the trade-in is worth, negative equity can increase the amount financed.

What affects the amount financed?

Vehicle price, sales tax, fees, down payment, trade-in value, and any amount owed on a trade-in can all affect the amount financed.
