Seven-day life formula: seven-day annualized rate of return = investment income/principal /7×365× 100%.
For example, the 7-day annualized rate of return shown by the Monetary Fund on the same day is 3%. If the next year's income can remain unchanged, the annual rate of return is 3%.
The calculation formula of seven-day annualized rate of return for deferred data should be different under different income carry-over methods.
At present, there are two ways to carry forward money market funds:
One is "daily dividend, monthly carry-over" and the other is "daily dividend, daily carry-over".
Whether it is carried forward on a daily basis or on a monthly basis, it is equivalent to compound interest.
The formula of compound interest is: {[π (1+ri/10000)] (365/7)-1}×100% π means continuous multiplication i= 1. . . seven
Where Ri is the nearest i-th Gregorian calendar day (i= 1, 2? .. 7) Earnings per ten thousand shares.
The regulatory authorities in some countries have strict formulas for calculating the seven-day annualized interest rate: if the value of a monetary fund before the first day of trading is A, the value after the seventh day of trading is B, and the fee for these seven days is C (sometimes, for example, Yu 'ebao, according to the situation of 20 14/3/ 15, C=0).
