You could try toggling a setting:
tools|Options|edit tab|Extend data range formats and formulas

But I think I'd provide a macro that inserted the row and filled the formulas.

David McRitchie shares some code:

look for: InsertRowsAndFillFormulas

I have a data sheet where I have to add a formula to the last 2 columns. The
number of rows changes with each new data sheet and can be several thousand
rows.

The sheet is called "JobLabour". The last column is Y and the data starts
below the heading "Line Property" at "Y7" (this could change, although I have
control over the report format).

I enter a formula (from the macro code) ,
"=IF(RC[-13]=""wlpn"",80,IF(RC[-13]=""2alpn"",44,IF(RC[-13]=""1alpn"",36,IF(RC[-13]=""3alpn"",60,IF(RC[-13]=""4alpn"",71,80)))))" at cell Z8.

I have the formula, "=RC[-8]*RC[-1]" in cell AA8.

I need to copy this down to the last populated value in col "Y".

Is there code that will do this automatically when new data is pasted into
sheet "JobLabour"?

I currently do this via a macro, but users often forget to run it and I have
to set the number of rows to fill.
