As a routine financial management project with guaranteed capital and interest, the normal income range is about 8%- 15% per year. If it is exceeded, it often means high risk. No matter what project it is used for, it will not exceed this range. Because the annual interest rate of many fund wholesale is probably within this range. If it is too high, there is absolutely no need for the financier to raise funds externally.
