Suppose you wanted to check the % complete for, say, A2:M2.

This is one formula:

=COUNTA(A2:M2)/COLUMNS(A2:M2)

Be advised that it will count a cell that has a formula, even if that formula evaluates to a zero length string.

If you need to exclude all empty cells, as well as cells whose values are zero length strings, you'd use an array formula like this:

{=SUM(IF(A2:M2<>"",1,0))/COLUMNS(A2:M2)}

To enter an array formula, do not enter the curly braces, and hit Ctrl+Shift+Enter instead of Enter to finish it off.  Excel will then display those braces to indicate that it's an array formula.
