There are generally three kinds of fees for purchasing open-end securities investment funds: one is to pay "subscription fee" when purchasing newly established funds; Second, the purchase of old funds needs to pay a "subscription fee"; Third, you need to pay a "redemption fee" when the fund is redeemed. The general subscription rate is 1.2%, the subscription rate is 1.5%, and the redemption rate is 0.5% (money market funds are free).

The calculation formula of fund subscription is: subscription fee = subscription amount × subscription rate. Net subscription amount = subscription amount-subscription fee+interest subscription share from subscription date to fund establishment date.

The calculation formula of fund subscription is: subscription fee = subscription amount × subscription rate. Subscription share = (subscription amount-subscription fee) ÷ Net value of the fund unit on the application date.

The calculation formula of fund redemption is: redemption fee = redemption share × net value of fund unit on redemption day × redemption rate.
