When can a credit company adjust the apr?

A credit company can adjust the APR (Annual Percentage Rate) under several circumstances, such as when a borrower misses a payment, exceeds their credit limit, or if there’s a change in the borrower’s credit score. Additionally, if the terms of the credit agreement allow for variable rates, the APR may change based on market conditions or an index rate. Creditors must typically provide notice of any changes in APR, as required by law.
