Rather than paying interest on principal plus accrued interest, you only have to worry about paying interest on the principal. Therefore, you won’t spend nearly as much on interest compared to loans that compound interest.
Aside from your car note’s principal and interest, you still have to pay other expenses associated with car ownership. This means that you need to budget for gas, maintenance, a possible emergency fund, and car insurance. While you can’t control how much you spend on maintenance and gas in most cases, you can save money on car insurance.
