A car loan balance barely moves in the first few months because any type of installment loan is front-loaded with interest. This means that you’re paying interest on the total balance of your loan at the current moment. The higher the balance is, the more you pay toward interest and the less you pay toward the balance.
The longer you go into the loan, the more money goes toward the principal rather than interest. Over time, you’ll see your balance go down exponentially compared to the first few months. Just have patience, keep paying on time, and you’ll see results.
