It is really troublesome to determine the return of each period in the calculation formula of the fund's fixed investment return. Actually, it's not necessary Because the net value of the fund is different when deducting money in each period, the cost of the fund is also different, and it is really tired one by one. Ordinary investors can consider examining the rate of return of a fixed investment period.

In fact, we can still use a very simple formula: fund present value/fixed investment cost-1.

Subscription:

(Subscribe according to the amount, that is to say, buy a fund of 6,543,800 yuan+10,000 yuan):

Suppose that the net value of a fund on the day of subscription is 0.850 yuan.

1, subscription fee (subscription amount × subscription rate):10000x1.5% =1500 yuan.

2. Actual subscription amount (subscription amount-subscription fee):100000-1500 = 98500 yuan.

3. Subscription share (actual subscription amount ÷ net fund value on the subscription day): 98500 ÷ 0.850 =115882.35.

Redemption:

(Redemption by share, that is, xxxx shares of the redemption fund):

Suppose the net value of a fund on the redemption date is 1.250 yuan.

1. Total fund (holding share × net fund value on redemption date):115882.35×1.250 =144852.94 yuan.

2. Redemption fee (total fund × redemption rate): 144852.94×0.5%=724.26 yuan.

3. Actual redemption amount (total fund-redemption fee):144852.94-724.26 =144128.68 yuan.
