This needs to calculate the income according to our principal and the specific fund increase. For example, if the amount of the fund purchased is 1 1,000 yuan, then after purchasing this fund at this time, my rate of return is 10%, so the income I can get is 1 1,000 yuan. This is our income from purchasing funds. Of course, this income needs to be quoted. Only by putting all the money into our own account can we calculate the real income, otherwise we can only calculate the floating profit, not the real income. So there is a saying: it is safe to leave the bag. After getting a good profit, you can consider selling it all and then find a time to continue buying. This is the best case.

Different capital investors will have this great difference in principal. Some people buy funds with large principal. Of course, the principal of most fund investors is around tens of thousands of yuan. It is not that their net worth is only tens of thousands of yuan, but they just spend tens of thousands of yuan to buy funds.

A very important concept in investment funds is to invest with spare money. If we invest with very important money, once trapped, it will bring great trouble, which is not so convenient for us to use our own funds. Therefore, it is very important to invest with spare money and hold it for a long time. Different principal will lead to different returns. At the same time, everyone buys funds at different times, and the fund returns at different time points are also different. At this time, it is necessary to calculate the overall income according to the principal and the rate of return.

Therefore, the income of the fund needs to be calculated according to the principal and rate of return. At this time, we need to see how much we spent on this fund and what is the overall rate of return during the holding period. The higher the rate of return, the higher our income, and the lower the rate of return, which may bring losses.
