Investing 1000 yuan in the fund every month, assuming the annualized rate of 10%, how much will it cost after 30 years, 10 years and 20 years with compound interest? If there are ten principals
The first type: the time span is 10%, that is, every month 10%÷ 12 = 0.83%, then the sum of your principal and interest in the first month = 1000× (1+0.83%).
The second one is easy to calculate, because you are not a fixed investment, and there is no new principal: 65438+ million× (1+10%) to the power of n, where n is the year of your investment, and it has doubled in more than seven years.
