At the core, this formula simply divides tasks complete by the total task count: which is then formatted as a percentage. To count completed tasks, we count non-blank cells in the range C5:C11 with the COUNTA function: Unlike the COUNT function, which counts only numeric values, COUNTA will count cells that include numbers or text. To count total tasks, we count non-blank cells in the range C5:C11, again with COUNTA: After COUNTA runs, we can simply the formula to: Four divided by 7 results in the decimal number 0.571428571428571 which is displayed as 57% once the Percentage number format is applied.
