There is no interest when the credit card is paid in full. Under normal circumstances, the credit card fee rate is 0.05% per day, and the upper and lower limits are strictly set in accordance with the relevant regulations of the People's Bank of China, and are adjusted in a timely manner according to regulatory requirements.

There is a difference between full payment and minimum payment on a credit card. Full repayment of a credit card means that the cardholder pays off the "full repayment amount" listed on the current bill before the due date of payment. If the cardholder repays the payment in full on time, the consumption on the current bill will be repaid in full. The transaction enjoys interest-free repayment treatment.

The minimum repayment means that the cardholder pays off the "minimum repayment amount" shown on the bill of the current period before the due payment date. In this case, it will not affect the cardholder's personal credit. However, since the payment has not been repaid in full, consumption transactions are not interest-free. Interest will be accrued from the date the consumption is recorded, and compound interest will be accrued on a monthly basis. According to regulatory requirements, starting from May 26, 2018, credit card cash withdrawals and cash transfer principals will be fully included in the minimum repayment amount.

1. How to calculate credit card interest:

Credit card interest is calculated on a daily basis. Interest = unpaid amount * number of days unpaid * 0.05%. Credit card payments can only be made overdue. Interest will accrue under certain circumstances such as payment, minimum repayment, overdraft withdrawal, etc. If interest arises during the use of a credit card, it is recommended to repay it in time, because the interest on the credit card is not paid off in the current month, and compound interest will be calculated in the next month.

2. How to calculate overdue interest on credit cards:

First of all, most banks calculate interest on the full amount.

The so-called interest accrual means that if the cardholder does not repay the balance in full, no matter how much the cardholder repays or how much is outstanding, the interest-bearing part will be the amount owed. Payment in full. To put it simply, you owe the bank 10 yuan, and you repaid 4 yuan on the repayment date, and you still owe 6 yuan. You think the interest calculation part should be 6 yuan, but in fact the interest calculation amount by the bank is 10 yuan. Secondly, banks generally use recurring interest calculation.

The so-called recurring interest calculation means that for every consumption on the bill, including the unpaid amount of the previous month, an interest of 0.5% per day will be charged starting from the recording date (usually the second day after the card payment is made). Until the day when part of the repayment is received first; then, interest will continue to be calculated based on the remaining unpaid portion until the next repayment, and the cycle continues.

Again, it is worth noting that interest is calculated from the date of consumption.

Currently, the interest rates for overdue credit card repayments in all banks are the same, which is 0.5% per day, and compound interest is calculated on a monthly basis. The interest accrual time is: interest accrual starts from the day of consumption.
