Applying for installment actually increases your repayment amount. Because there is a handling fee for installment, there are generally three, six and 12 installments, and the handling fee is 2.6%, 3.2%, 4 and 2% respectively. Since you're not going to use it, you might as well pay it in one lump sum.
Besides, you have only paid the minimum repayment amount, so it is unlikely to apply for installment. At the same time, only the minimum repayment amount is paid, and all the money does not enjoy the interest-free day, that is, the interest of 2500+ your minimum repayment amount starts from the bookkeeping date, and the interest is calculated at five ten thousandths per day.
