Can APR change over time? The APR, or Annual Percentage Rate, can change over time depending on the terms of the loan or credit agreement. For example, with a variable-rate loan, the interest rate can fluctuate over time, which would also cause the APR to change. In contrast, with a fixed-rate loan, the interest rate remains the same over the life of the loan, which means the APR would remain constant as well. In addition, the APR can change if the lender charges additional fees or changes the terms of the loan agreement. For example, if a lender increases the origination fee or imposes a penalty for late payments, the total cost of borrowing would increase, which would cause the APR to go up. It’s important to carefully review the terms and conditions of any loan or credit agreement to understand how the APR can change over time. If you have any questions about the terms of the loan or the APR, it’s a good idea to consult with a financial professional or the lender directly.
