If i want to invest 4million$ for 17 years what will my next amount of money be in the future?

At what interest rate??

10%

Your $4,000,000 will be worth =$20,217,881.14 @ 10% over a period of 17 years.

This is the formula to use: FV = PV[1 + R]^N =4,000,000 x 1.10^17 =4,000,000 x 5.05447.....

=$20,217,881.14.
