Every fund is different. The following is the general situation. Which fund are you interested in? You can check it on the website of that fund company.

General stock funds buy (subscribe) 1% to 1.5%, and sell (redeem) about 0.5% (holding time will generally be reduced);

The bond fund is at a low point, the subscription is about 0.5%, and the redemption is low or not;

The money fund does not charge fees.

If the amount is large (the standard stipulated by general fund companies is 5 million yuan), the upper limit of subscription fee is 1000 yuan.
