echo
add a line break at the end of its output, which is counted as a character by wc -c
. You can use echo -n
to omit the line break, and get the result you're expecting:
[mureinik@mureinik ~]$ echo -n abc | wc -c

From man wc
:
wc - print newline, word, and byte counts for each file
As the rest of the answers indicate, the new line is also counted as character.
See:
$ echo "abc" | wc
1 1 4
^
characters
$ printf "abc" | wc
0 1 3
