Longer repayment periods will help spread out the payments, making your monthly bill lower, but they will often cost more over time. Since interest accrues on your loan, the longer it takes to repay the loan, the more you’ll owe. If you can afford a shorter repayment period, it will lower the final cost of your car loan.
To ensure you don’t get a loan with bad terms, be sure to shop around with various lenders. Every lender will offer different loan conditions and terms. By shopping around, you can find out exactly what your loan length options are and what you’d be paying.
