The credit card spent 2000 yuan last month, and the minimum repayment was 200 yuan. If only the minimum repayment amount is paid, the rest will be paid next month. How to calculate the interest?
If the full repayment is not made in the current month, the bank will charge 5/10000 interest on all overdrafts on a daily basis from the bookkeeping date to the repayment date until the principal and interest are fully paid off.
Interest = total consumption amount ×0.05%× days from bookkeeping date to first repayment date+unpaid amount ×0.05%× days from first repayment date to second repayment date.
