For example, if the interest rate is 50,000 per day, the monthly interest rate is 2,250 yuan.

Credit card interest is calculated based on the outstanding amount and interest rate on the credit card statement. The credit card limit is 150,000 yuan. When withdrawing cash from an ATM, the maximum amount is 2,000 yuan per day. The cash withdrawal fee is 1 and the minimum is 10 yuan. The handling fee for withdrawing 150,000 yuan is 1,500 yuan. The interest is calculated at 50,000 yuan per day, starting from the next day when the cash is withdrawn. Starting from the calculation, one month’s interest is 150,000*5*30=2,250 yuan.
