Just divide the total cost by the total number of shares:

=SUM(D:D)/SUM(A:A)

Hi, I need a formula to achieve a average for some mutual funds I have
purchased over a period of years.
Column A contains the number of shares I have purchased and Column C contain
the price per share and Column D contains the cost for these shares. For
example column A2 contains 130.29 and Column C2 contains $18.30 and Column
D2 contains $2,484.25. Each cell in Column A contains a different number of
shares and likewise so does column C and D. I have 40 cells in Column A each
with a different number of shares and Column C has 50 cells each with a
different amount per share and Column D will have a different amount in each
cell. I need to obtain an average cost per share. Is there a formula I can
use to obtain this? Any help or advice you can provide will be greatly
appreciated.
