How much income you get from buying a fund of10 million a day depends on the fund you choose. The benefits of not using the fund are different. The calculation formula of daily income of the fund is: daily income = fund share * ten thousand income of the fund on that day/10000. The fund income is calculated according to the income per 10,000 shares or the seven-day annualized rate of return given by the fund operator every day. For example, if an investor holds a money fund, the income per 10,000 shares today is 1.5692 yuan, and the annualized rate of return on the 7th day is 4.9760%. If he holds 10000 shares, he can get 1.5692 yuan that day.
