Front-end charges and back-end charges include subscription fees, redemption fees and management fees. Take you as an example here, only the subscription fee and redemption fee are calculated. There are some known conditions to be supplemented here: a fund of 1 yuan is redeemed at 10000 yuan, with a daily net value of 0.965 yuan and a redemption rate of 0.5%.

Calculated by front-end charging mode:

Fund share = 10000 yuan /( 1+0.6%)=9940 copies (this is not only the money that can be used to buy funds, but also the fund share).

Subscription fee = 10000 yuan -9940 yuan =60 yuan.

Redemption fee =9940 copies ×0.965 yuan ×0.5%=47.96 yuan.

Calculated by back-end charging mode:

Because it is a back-end fee, the fund share = 10000.

Subscription fee =10000×1.8% =180 yuan (according to your form, if it is redeemed within 1-2 years, multiply it by 1.5%, and so on).

Redemption fee = 10000 ×0.965 yuan× 0.5% = 48.4 yuan.

Using the back-end charging model, because there is no charge at the beginning, the fund share is much more than the front-end charging.

This method can be used to calculate the back-end charging mode of redemption in different years. Of course, the fixed investment you mentioned can be calculated simply by adding the total amount to the formula.

It is not difficult to see that, as far as your example is concerned, if the back-end charging model is adopted, it will only be cost-effective if you hold the fund for more than four years. If you invest within four years, it is recommended to use front-end charges.
