Is there a formula out there that will sum every nth row? I have a template
that has the same measure in consecutive rows and rather than selecting the
cells manually would like to enter a formula.

Thanks for the help.

Go to this page Chip Pearson's site and scroll down to "Summing every nth
value"

=SUMPRODUCT(--(MOD(ROW(B1:B100),n)=m),B1:B100)

where n is the nth row, m is the start point, and should be 0 and <=n-1

Say you want to sum every 3rd row and your data starts from A1 thru A42 the
following will sum every 3rd row

=SUM(IF(MOD(ROW(A1:A42),3)=0,A1:A42))
Array entered (ctrl+shift+enter)

Now changing 3 to 4 in the fomula will sum every 4th row

However be careful with the beginning row number where the sum range begins
as this formula would need tweaking to adopt to that
