Excel formula: Project complete percentage

Generic formula

=COUNTA(range1)/COUNTA(range2)

Explanation

To calculate the percentage complete for a project with a list of tasks, you can use a simple formula based on the COUNTA function. In the example shown, the formula in F6 is:

=COUNTA(C5:C11)/COUNTA(B5:B11)

How this formula works

At the core, this formula simply divides tasks complete by the total task count:

=complete/total

which is then formatted as a percentage.

To count complete tasks, we count non-blank cells in the range C5:C11:

=COUNTA(C5:C11)

To count total tasks, we count non-blank cells in the range C5:C11:

COUNTA(B5:B11)

Unlike the COUNT function, which counts only numeric values, COUNTA will count cells that include numbers or text.
