If I remember correctly, the installment interest of credit cards is generally between 8% and 16% per annum. If the personal loan calculator is used to calculate according to 16%, it will be 2,700 yuan in six installments, and the monthly principal and interest should be 486 yuan.
Personally, the installment interest of bank credit cards is still very high. Don't pay by installment unless you have to. You'd rather see if there is any discount when you swipe your card. For example, many bank credit cards will have interest-free or preferential installment interest cooperation in Apple, official website and vivo.
