VBA code for COUNTIF formula to determine different end of range

[willow1985]

Hello,

I am looking to speed up a macro of mine, specifically a COUNTIF formula and I was wondering if the following is possible:

My COUNTIF formula is basic: =COUNTIF(A:A,A2)

When I utilize it I am doing so by entering the VBA code:

 LastRowColumnA = Cells(Rows.Count, 1).End(xlUp).Row
Range("T2:T" & LastRowColumnA).Formula = "=COUNTIF(C[-19],RC[-19])"

to determine what the last cell is in which to copy down the formula, however the count if formula is still referencing all of column A.

Is there a way to modify this formula in VBA to determine where the data in A ends so I do not have to reference it all? Would this speed up the calculation?

Any ideas would be greatly appreciated, thank you

Countif only uses the used range, so as long as the usedrange is reporting correctly there shouldn't be any change in performance.
If you do Ctrl End does that take you to the last row with data?

I found that it wasn't the formula being slow but having the formula in place while using filters afterward. I fixed this by using the COUNTIF formula to get the data, copy and pasting the results as special values (therefor removing the formula) and then manipulating the data (filters etc).

Thank you for your help. I have another question but since it is unrelated to the title of this post I will start a new thread.

Thank you again
