The subscription fee is charged through external deduction. Precisely
Net subscription amount = subscription amount /( 1+ subscription rate), subscription fee = subscription amount-net subscription amount, subscription share = net subscription amount on the subscription day/net fund share value.
The rate is relative, the front end 1.5%, and now the fund direct sales is 40% off, which becomes 0.6%.
Let me calculate for you: 20000 divided by (1+0.6%)= 19880.72 net subscription amount.
Subscription fee = 20000-19880.72 =119.28 yuan.
