Answer:
Both APR and fees
Step-by-step explanation:
The Annual Percentage Rate -APR is the interest rate a customer pays on a credit card per year. Credit cards extend loans to the holder every time they are used. If the credit card user does not pay the full amount on the due date, it attracts interest charges. The higher the APR, the more interest a cardholder will pay. In selecting a credit card provider, APR is the most important factor to consider.
Credit card attracts other fees other the interest. These fees include Balance Transfer Fee, Foreign Transaction Fee, Annual Fee, and Cash Advance Fee. These fees affect the customer's overall cost of using the credit card. Customers should compare different credit card companies and select one with favorable fees.
