# Sum data for a given range of months (if months are number or text)

Experts,

if given:
1/1/2016   1/2/2016  2/1/2016  2/15/2016  3/1/2016
with costs of
10/20/40/50

Sum the costs for these months:
if month is text:
January, February, March

if months are given in month format:
1/1/2016; 2/10/2016; 3/25/2016

What is the formula to sum those costs based on the months?
I am not sure if I should use SUMIF (as an array) or SUM PRODUCT.

Please see attached spreadsheet with necessary data and the formulas I have used but note they are not correct formulas.

thank you in advance....

See if this works for you...

``````=SUMPRODUCT((\$B\$5:\$ALD\$5<>"")*(TEXT(\$B\$5:\$ALD\$5,"mmmm")=B\$15)*\$B\$6:\$ALD\$6)
``````

nice.  it worked for the months in text.
Would you have a suggestion for the months in digit format (ie 1/1/2016)

thank you

If the dates criteria are in row7, try this....

``````=SUMPRODUCT((\$B\$5:\$ALD\$5<>"")*(MONTH(\$B\$5:\$ALD\$5)=MONTH(B\$7))*\$B\$6:\$ALD\$6)
``````
