    Sum of units over a time period starting with initial units and a known growth rate

    Hello,

    I am trying to calculate the total value of units over a time period (ex. 5 years) with a known number of units in the first year (ex. 1000) and a known growth rate (15%) per year. I'm not interested in the final value, but rather then sum of year 1, year 2, year 3, year 4, year 5 values. Put another way if I was making widgets, I want to know how many widgets I would sell over that period given the initial volume and known growth rate.

    Thanks!

    =A2*(1+A6)^A4

    Re: Sum of units over a time period starting with initial units and a known growth rate

    Thank you for the super quick reply. I was wondering if there was a way to find the sum of the units across five years i.e in this example it would be 7754 (=SUM(E2:E6) without having to calculate each year separately?

    Thank you!

    Try

    =SUMPRODUCT((A2*(1+A6)^D2:D6))

    or

    =SUMPRODUCT(($A2*(1+$A6)^{1,2,3,4,5}))
