Financing 101: APR, Loans, and Lease vs. Buy Explained

Auto financing can feel like a separate negotiation on top of the car purchase itself. Understanding the key terms before you sit down with a finance manager removes most of the stress.

APR, or annual percentage rate, is the effective interest rate you will pay on the loan, including fees. It is the number to compare when a bank or dealer offers you financing, not the monthly payment. A difference of even one or two percentage points can add up to thousands of dollars over a multi-year loan. Your credit score, loan term, and the age of the car all affect your APR. Generally, shorter terms have lower rates, and new cars qualify for better rates than used ones.

Loan term is the length of time you have to repay. Sixty months is common, but terms of 72 or 84 months are increasingly offered. A longer term lowers your monthly payment but increases the total interest you pay over the life of the loan. The car also depreciates during that time, which can leave you owing more than the car is worth -- a situation called being upside down on the loan.

Leasing is essentially renting the car for a fixed period, typically two to three years, with mileage limits. Monthly payments are lower than buying, and you can drive a new car every few years. The downside is that you never build equity, you are restricted by mileage limits, and there are fees for excess wear or early termination. Leasing makes the most sense if you want a new car regularly and drive predictable, lower annual mileage.

Buying makes more sense if you plan to keep the car for several years after the loan is paid off, drive high annual mileage, or want the freedom to modify or sell the car at any time.
