In a helper column you could put this formula on row 1:

=INT(ROW()/15)

and copy it down. It will give you 15 zeros, followed by 15 ones, then
15 twos etc, so you could use the Data | Subtotals feature using this
column to determine where the subtotals should go (i.e. for each
change in this column ...).

Hope this helps.

I know how to use the Subtotals tool but the only option there seems to be
subtotals based on the change in values of a column. *In my case I don't care
about the values of any columns, I just need the subtotals every 15 rows.

Of course I could do this manually, but I'm hoping there's a quick and easy
way to do it similar to how the built-in Subtotals tool works.

Thank you.
