It's hard to explain to you!

The principle of the fixed investment calculator is: artificially set the annual profit, and the calculator will automatically turn the annual profit into a monthly profit. The calculator uses this month's profit value and fixed investment funds and years to calculate.

You can't consider the actual increase every month like you. It is impossible to know such an increase until the final result comes out. What's the point of using a calculator when the net value comes out?

Just like tossing a coin, the positive and negative probability is 50%, which may not be reached several times, but after tossing it many times, this ratio is established.

The same is true of funds. For example, the average annual growth of funds 10% may be quite different from that of one year or two years, but the statistical value of 10% has been more significant in the past 50 or 60 years.

……

Tell you a conclusion: the fixed investment calculator has scientific basis, supported by probability theory and stochastic process!
