How to count the number of times a number is repeated in a column

I want to count (sum) the number of times any number is repeated in a column. Any ideas for a formula to do this? Column F: Range F2-F1958. I have been trying multiple iterations with COUNTIF for hours w/o success.

I would probably use the FREQUENCY function for this, unless it needs to
be dynamic? I tend to use the Countif method if instant total update is
what I need, though.

Try:

=SUMPRODUCT(--(FREQUENCY(Rng,Rng)>=2))

where Rng = F2:F1958
