Examples are as follows:

I. Purchase:

Suppose a fund is subscribed with 1 0,000 yuan, the subscription rate is 1.5%, and the net value of the day is 1.2000.

Net subscription amount = subscription amount ÷ (1+ subscription rate) =10000.00÷ (1+1.5%) ≈ 9852.22 (yuan)

Subscription fee = subscription amount-net subscription amount =10000.00-9852.22 =147.78 (yuan)

Subscription share = net subscription amount ÷T-day fund share net value = 9852.22÷1.2000 ≈ 8210.18 (copies)

Second, redemption:

Assuming that the fund is redeemed after one month, the redemption rate is 0.5% and the net value of the day is 1.4000.

Total redemption amount = redemption share ×T-day fund share net value = 8210.18×1.4000 ≈11494.25 (yuan)

Redemption fee = total redemption amount × redemption rate =11494.25× 0.5% ≈ 57.47 (yuan)

Net redemption = total redemption amount-redemption fee =11494.25-57.47 =11436.78 (yuan)

Net profit =11436.78-10000.00 =1436.78 (yuan)
