You only need to pay late fees and interest when you pay back the money.
1. The late payment fee is calculated as the percentage of the unpaid part (that is, 3,000 yuan), which seems to be 1%. I can't remember clearly.
2. Calculate the interest at 0.5 ‰ of the total overdraft every day (i.e.11 1000×0.0005× overdraft days).
Overdraft days: 65,438+065,438+0,000 yuan, from the date of first consumption to the date of repayment.
