Different types of credit cards have different annual fees. The cost of installment is calculated by multiplying the total amount of installment by the current installment rate. I don't know which bank you are talking about. The annual fees of commonly used banks are as follows:

1. ICBC peony international credit card (dual currency) ordinary card:100; Gold card: 200 peony credit card (RMB) Ordinary card: 50; Gold card: 100

2. China Construction Bank Longka Credit Card (Dual Currency) Ordinary Card: 80; Gold card: 160 longka credit card (RMB) ordinary card: 60; Gold card: 100

5. ABC Jinsui Credit Card (quasi-credit card) ordinary card: 20; Gold card: 80

6. Bank of Communications Pacific Credit Card (RMB) Ordinary Card: 80; Gold card: 160

The repayment interest of each bank will be different. The cost of installment is calculated by multiplying the total amount of installment by the current installment rate. Generally 0.5%, I hope my answer can help you!
