Frequently Asked Questions
How does a vehicle trade-in lower auto loan payments?
Your trade-in value acts like a cash down payment by reducing the total loan principal required to buy the car, which directly lowers both your monthly payment and total interest paid.
Does this auto loan calculator include sales tax?
Yes! The calculator automatically computes your state sales tax on the net vehicle purchase price (Price minus Trade-in) and rolls it into your financing total.
What is a good loan term for a new or used car?
Common auto loan terms are 48 or 60 months. While 72-month or 84-month loans offer lower monthly payments, they result in paying substantially more total interest over time.
