The external deduction method aims at the subscription amount, that is, the total investment. The subscription amount includes subscription fee and net subscription amount, and the calculation formula is as follows (the specific charging method and rate standard of a single fund are subject to the relevant provisions in its offering announcement and prospectus):

Subscription fee = subscription amount × subscription rate

Net subscription amount = subscription amount-subscription fee

Subscription share = net subscription amount/par value of fund unit

Subscription amount includes subscription fee and net subscription amount, and the relevant formula is as follows:

Subscription fee = subscription amount × subscription rate

Net subscription amount = subscription amount-subscription fee

Subscription share = net subscription amount on T day/net fund share.

Fund companies often use the "internal deduction method" when purchasing funds. For example, you bought a new fund with 65438+ 100000 yuan, and the new fund has 1 yuan. If the rate is 1%, if the subscribed fund share is calculated by "internal deduction method", the corresponding formula is:10000-/kl. Using the deduction method, the corresponding formula is: 1 0000/(1+1%), the same1ten thousand yuan, and the fund share that can be purchased is 9900+438+0. According to this calculation, for every 100 0 yuan new fund, investors can save nearly 100 yuan.
