Total investment cost divided by the total share of funds purchased. There is no redemption fee here. If the redemption fee is calculated, it needs to be multiplied by 99.5%.

Secondly, it should be clear that the fixed investment amount of the fund must be the same every month, and it is not possible to buy 1000 this month and 200 next month. As for the calculation of the cost, it is very simple, that is, how much money is invested, such as 1000 yuan per month, and 12000 yuan after two months.
