1. Seven-day annualized rate of return calculation formula Under different income carryover methods, the seven-day annualized rate of return calculation formula should also be different.

At present, there are two methods of income carryover for money market funds. One is "daily dividends and monthly carryover", which is equivalent to daily simple interest and monthly compound interest.

The other is "daily dividends, carried forward on a daily basis" which is equivalent to daily compound interest.

Among them: the simple interest calculation formula is: (∑Ri/7)×365/10000 units×100%. The compound interest calculation formula is: (∑Ri/10000 units)365/7×100%.

Among them, Ri is the income per 10,000 shares on the most recent i-th calendar day (i=1,2…..7), and the fund’s seven-day annual return rate is rounded to three decimal places.

2. Seven-day annualized interest calculation formula: one day's income = principal * seven-day annualized return/360: According to expert analysis, the seven-day annualized return is calculated by summing up the net income of every 10,000 products in the past seven days.

The seven-day annualized rate of return as an average indicator can only reflect the approximate fluctuations in the past seven days.

A certain product's short-term seven-day annualized rate of return is extremely high, which may mean that the investment manager's operating style is relatively aggressive. The daily income that users receive is often a bit like a roller coaster. For ordinary users, stable high income is king.

The larger the monetary fund, the greater its say in investment and the higher its returns.

However, some monetary funds use "term products" or "self-subsidised" to express high returns, but this high return cannot last long.

Experts believe that compared with the seven-day annualized return, consumers in financial management should pay more attention to the net return per 10,000 products or the total return per 10,000 copies.

The daily income of 10,000 shares is the actual income obtained on that day; and the 7-day annualized rate of return is the annualized rate of return based on the past 7 days of income, which is not the real rate of return every day.

When looking at product returns, investors should focus more on long-term performance stability.

In addition, when selecting products, investors should make a comprehensive comparison, including specific returns, specific stability, specific subscription thresholds, specific withdrawal flexibility, specific usage scenarios and other conditions.
