1. Fixed fee: Some fund decision-making platforms will charge a fixed fee, such as a certain monthly or annual management fee. This cost will not change with the increase or decrease of investment.

2. Percentage fee: Another common way is to charge a fee according to the percentage of the investment, such as 0.5% or 1%. This means that the greater your investment, the higher the handling fee.

3. Mixed charging: Some platforms will adopt a mixed charging method of fixed fee plus percentage of investment.

4. Step rate: Some platforms have set the step rate. After the investment exceeds a certain level, the rate will be reduced.
