How does an auto loan calculator work?

It calculates your monthly payment by taking the total vehicle price, adding sales tax, and subtracting down payment and trade-in value, then amortizing the balance over your chosen monthly term.

What is trade-in value?

Trade-in value is the amount a dealership is willing to pay you for your existing car, which is deducted directly from the purchase price of your new car.

How can I lower my monthly car payment?

You can reduce your monthly payment by increasing your down payment, choosing a longer loan term, securing a lower interest rate through pre-approval, or trading in your current vehicle. Each 1% reduction in APR on a $30,000 loan over 60 months saves about $13 per month.
