Row Count parameter in powershell

I am not a powershell expert so please help!

I have a script which counts rows in the .csv file, I want to add "2 additional counts" to my row count for header & footer eg if the row count is 10 it should print 12 (10 + 2). I tried to add @($csv).count+2 but it didn't work. Any ideas how I can do that.

Below is the script -

$csv = import-csv E:\BBUser.csv
"{0}|{1}" -f "***FileFooter", @($csv).count | Out-File -append E:\BBUser.csv

Thanks in advance. Please let me know if you need additional information
