Your monthly payment depends on four main things: the vehicle price, your down payment, your interest rate (APR), and your loan term (how many months you finance).

**Here's the simple math:** A larger down payment and shorter loan term lower your total interest but raise your monthly payment. A longer term spreads payments out, making them smaller each month but costing more in interest overall. Your APR (interest rate) depends on your credit profile and current market rates.

Our Finance team can show you real payment estimates once you've chosen a vehicle and we've reviewed your credit. For an accurate estimate on the vehicle you're interested in, **call (630) 864-6683**. They'll run the numbers and show you how different down payments and terms affect what you pay each month.
