<human>:  I am buying a car and I want to calculate my monthly loan payments. Can you help me find out how to use a car loan calculator?
<bot>: To use a car loan calculator, you need to know several pieces of information. First, you need to specify the total loan amount, the loan term (usually in months or years), the annual interest rate, and any down payment you may have. With this information, the calculator will provide you with the total cost of the loan, the total amount that you will need to pay each month, and the total interest you will pay over the life of the loan.
