1. Hallo

The attached sheet has projects & weights

plus completion

How can I calculate the completion as per the weight?

Thanks

2. In d3:
=C3*B3/\$B\$10

Copy D3 to D49

You can also eliminate the intermediate column if desired and calculate the weighted completion average as [currently in D10 as =SUM(D39)]:
=SUMPRODUCT(B3:B9,C3:C9)/SUM(B3:B9)

3. Thank you Steve

4. Attached is the updated version. I wonder if the Weighted average is correct?

Also, the numbers look somewhat abstract and meaningless - is there something we can do to make it more meaningful?

On the first point, notice that the sum of D39 equals D10, so it looks right in context. (Just in case: if column B is actually percentage and should always add to 100%, you don't strictly need the "/SUM(B3:B9)" part of the formula in cell D10 - it's dividing by 1, which as we know...)

As to your second question, formatting is in the eye of the beholder, but it appears that all column D values should be formatted as percentages, and you could format the Borders on row 10 to be show that this is the total section; with no borders at all that row looks like scratch pad calculations rather than a presumably important Total/Average row. And if Column B is percentages, format them that way.
