Bill, your formula works great.

How would you modify that to also yield a YTD result, i.e., Aug is
selected it sums Jan through Augus from the same dropdown.

You'd have to use a different function.

A2:A15 = cost center
B2:B15 = account codes
D1:O1 = column headers as month names (January, February, March, etc.)

Lookup values:

A17 = some cost center
B17 = some account code

A18 = drop down list with the month names (January, February, March, etc.)

=SUMPRODUCT((A2:A15=A17)*(B2:B15=B17)*D2:D15:INDEX(D2:O15,,MATCH(A18,D1:O1,0)))
