Option 1:
On possibility is you wish to calculate the total cost for each item, where column A mentions No of Items & column B mentions Cost per Item - enter below in cell C2 & copy down:
=A2*B2
This will become =A3*B3 when copied to C3, and so on. This calculates total cost for each item separately.
Option 2:
In case you want to calculate the total cost of ALL ITEMS, enter below formula in cell E2:
=SUMPRODUCT(A2:A5*B2:B5)
This calculates the SUM of Total Cost of ALL Items (this is the same as C7 which is the total of column C.
Please update the range per your requirement. In case your query is otherwise then please illustrate the same or upload your file for an appropriate solution.
