Formula to Calculate % Complete


Hi there,

I have created a task sheet and want to calculate the % of completed tasks. Below is a picture of part of my sheet (there are a lot more tasks below). When an item is either ticked Yes or No, the Date field is auto populated. Once the Date field is populated the Completed cell turns from Red to Green. I would like my % completed cell to calculate the percentage of green/red.

Thanks in advance

    Hi @Hannah McHardy 

    Hope you are fine, first you need to use symbol column type (RGY) for completed column and make it's format % .to be able to count the green and red. then the following formula will give you the percentage

    Thanks for answering Bassam.

    I haven't previously made the Completed column a symbol because I wanted it to change from red to green based on the Date column being entered and I couldn't figure out how to do that. Which is why I have used conditional formatting to colour code.

    Any further tips?

    Thank you!
