Interest is the cost of borrowing money from the lender. With title loans, the interest at an annual percentage rate can be as high as 300%, or 25% in monthly interest charges. Factors determining interest rates include: Your credit score Your income or ability to repay the loan The length of the loan term The trade-in value of your vehicle Generally speaking, if you are a high-risk borrower, the lender will charge a higher interest rate for the loan.
