If you only use one cell then this will suffice

=LEN(A1)-LEN(SUBSTITUTE(UPPER(A1),"E",""))

you probably meant


=SUMPRODUCT(LEN(A1:A10)-LEN(SUBSTITUTE(UPPER(A1:A10),"E","")))

Try this:

I need to count the number of characters repeating within a cell. For
example, assuming the following in range A1 through A4:

eee
ee
aaaae
af

A count of "e" would return

3
2
1
