Article: Typically, buyers will make a cash down payment on their new car and borrow from a lender to cover the remaining cost. This borrowed amount, known as the principal, will serve as the basis for your car loan. Keep in mind that you should put as much money down on your car as possible to minimize the amount borrowed and reduce your finance charges. This step will require you to know roughly how much your new car will cost. See How to Buy a New Car for more information about finding a good price and working within your budget. The APR reflects how much additional money you will have to pay beyond your principal for each year of your loan. A low APR will reduce the yearly and monthly amounts of finance charges on your loan. However, many low-APR loans are longer in duration, so the overall cost may remain relatively high. Alternately, a short-term loan with a higher APR may end up being cheaper overall. This is why it is important to calculate your finance charges beforehand. Getting a low APR on your car loan may mean seeking other lenders beyond your car dealership. Be sure to do your research and select the cheapest available combination of APR and duration. See How to Get a Low APR on a Car Loan for more information. The majority of car loan payments are made on a monthly basis. When calculating your monthly payments, you will need to know both how many payments you will make each year and how many payments you will make in total. This information can be easily found in the terms of your car loan.
