Adding percentages that are produced by formulas

[28creation]

I can't believe you can't just add percentages with the usual =SUM(A1:A10) formula!!!

The percentages I want to add are all created by formulas, not typed into the cell itself. The total percentage at the bottom of the page is adding up the individual weightings from a number of entries.

How can this be done please?

Thanks in advance.

Try sumproduct

Thanks for the reply, but that doesn't work.

Do you have a column with the same number of percentages as what you're adding (10 in your example above)?

Of course you can. Whether the end result is meaningful depends on what those numbers represent and what you're trying to calculate.

If 50% of people own a car, and 30% own a house, you can't conclude that 80% own either a car or a house.

There are one or two empty cells in the column

where blanks are assumed to be zero. Is this close to what you're asking?

It is, but it returns error #VALUE !

You said the percentages are formula results, so they should be numbers not text. Can you show a sample of the data and formula?

The first cell is O8.

The #VALUE ! cells at the bottom are P26 & R26.

The code in the #VALUE ! cells are

=SUMPRODUCT(P8:P9,P11:P15,P17:P18,P22:P24)

&

=SUMPRODUCT(R8:R9,R11:R15,R17:R18,R22:R24)

Thanks.
