share calculation

the share held is equal to the sum of the shares purchased in each period.

the purchase share of a certain period is equal to the amount of investment in each period after deducting the handling fee divided by the net value of the day.

calculation of net value

the net value is equal to the holding share multiplied by the net value of the fund unit today.

calculation of the rate of return

the rate of return is equal to the net value of today minus the investment amount, and then divided by the sum of the investment amount in each period multiplied by the number of days held in the current period, divided by 365, and then divided by the total investment amount

Assuming that the monthly investment is 211, then the fund shares invested in 211 yuan are different, and the income is calculated until the end of the fixed investment, which is calculated according to the total share multiplied by the unit net value of the day. (Note: Share is the core, because the unit net value of each period is different, the share obtained in each period is different.) For another example, if the net value of a fund is 1.6 when it is purchased (it can't be 1.6 in each period), and its net value is 1.7 after the fixed investment ends three years, then the income is the total share multiplied by 1.7, and the yield is: (total share *1.7- total principal)/total principal * 11.
