 A1 * (1 + A2 / A4) ^ (A4 * A3)

  1. Use FV function: There is the formula of FV that is = FV(rate, nper, Pmt, PV)

pv= it’s the starting investment enter it in the formula

Rate divide the interest rate with the compounding frequency annually or some other.

Nper= multiple the number of years with the frequency

Pmt= If you are not adding money regularly enter 0
