1. Generally speaking, it is more cost-effective to choose installment repayment for a long time, and it is more cost-effective to choose the minimum repayment amount for short-term turnover. Take China Merchants Bank as an example. If you owe 1 0,000 yuan, pay it back in three installments, with the interest rate of 0.9% for one installment and the handling fee of 1 0,000 * 0.9% * 3 = 270 yuan. If it is divided into 12 installments and the single installment rate is 0.66%, then the handling fee is10000 * 0.66% *12 = 272 yuan;

2. Look at the minimum repayment amount, the principal 1 000 yuan, which is calculated according to the daily interest of five ten thousandths. After the minimum repayment amount 1 1,000 yuan, the amount owed by 9,000 yuan is about 285 yuan. There is little difference in the handling fee between China Merchants Bank and China Merchants Bank in three phases. If the minimum repayment amount is used throughout the year, then the interest expense should be at least two or three thousand.
