This kind of behavior is unwise, because the interest rate of cash installment is higher than that of borrowing.

Under normal circumstances, the actual annual interest rate of bank cash installment is higher than that of borrowing. For example, if you borrow 12,000 yuan, the monthly interest rate for bank cash in three installments is 0.82%. You need to repay a principal of 4,000 yuan + a handling fee of 98.4 yuan every month. The total handling fee, that is, the total interest, is 295.2 yuan. As for borrowing, if the monthly payments are equal, you need to repay 4,083.96 yuan every month, and the total interest is 251.87 yuan. There is a difference of 43.33 yuan between the two.

The interest calculation method for credit card cash installment is also different from borrowing money. This is also a feature of banks. On the surface, it is said to be interest-free, but in fact, it charges interest in the form of handling fees. The interest calculation method for borrowing money is relatively simple. It uses daily interest. The real annualized interest rate is almost (daily interest × 365). For example, the daily interest rate is 4/10,000, which is equivalent to about 14.6%.
