Google Spreadsheet sum which always ends on the cell above

Question

How to create a Google Spreadsheet sum() which always ends on the cell above, even when new cells are added? I have several such calculations to make on each single column s

Answer 1

General syntax:

=SUM(INDIRECT(cell_reference_as_string1 &":"& cell_reference_as_string2)

with for example:

cell_reference_as_string1 = ADDRESS(ROW(),COLUMN(),4)
cell_reference_as_string2 = ADDRESS(ROW()-1,COLUMN(),4)
