Excel - SUMIF with two columns

Asked By Joseph N. on 17-Oct-07 08:35 PM
[Excel 2003] Assume a worksheet with with numbers in column A; Boolean
criterion [Y or N] in column B; and another Boolean criterion [Y or N]
in column C.  I would like to add the numbers in column A for all rows
that have 'y' in both columns B and C.

I have been trying to do this with a SUMIF statement in which the
criteria is a combination of the two columns.  I have not been able to
find the magic formula, so either I am missing the correct syntax or
there is a better formula to use.

Help would be appreciated!

The double negation in terms two and three are there to convert True and
FALSE to 1 and 0, repespectivley
So we do not need them in the first term

As others have suggested, creative use of the sumproduct()
formula can do it. FWIW, Excel 2007 introduced a new function
called sumifs() that handles it natively.

More on using  sumproduct() for this purpose -

It a little longer but,what you can do is create a column D that equals  A&B&C and then do the sumif on column d.   Assume the value you want to sum is in e then the formula is:

Sumif (D1:D50,"YYY",E1:E50)
