Calculating Percent of Percentages
I think this should be easy but I keep getting "divide by zero" error. I just need to find the total percent complete using percents from 6 different columns (same row) on a sheet.
Ex: C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 TOTAL:
100% 100% 50% 100% 80% 20%
Thanks!!

I used this formula in a check box on another sheet:
=100*(COUNTIFS([FW % Complete]13:[FW % Complete]24, 1) / COUNT([FW % Complete]13:[FW % Complete]24)) + "%"
I just need to know a total percent complete. Thanks!

Ok. Because of the formula you used, the % Complete is actually producing a text string. We need to convert that to a number first before being able to use it in calculations. That's why I asked how the current % Completes were being generated.
.
To do this, you have two options. Either you can use a handful of extra helper columns with simple formulas, or you can use a single column with a more complex formula.
.
Extra helper columns solution:
One additional for each % Complete. I will just replicate column names based on your original post. The helper columns would be titled:
[C1 Helper]
[C2 Helper]
[C3 Helper]
so on and so forth.
.
The formula to pull the number from [C1] into the [C1 Helper] would be
=VALUE(SUBSTITUTE([C1]@row, "%", ""))
.
You would update this for the rest of the helper columns.
.
Now that you have numerical values to work with, you can use this in your [TOTAL:] column:
=ROUND(AVG([C1 Helper]@row:[C10 Helper]@row)) + "%"
.
.
Single Column Solution:
You would use a SUM function and enter the individual SUBSTITUTE functions as the values, then divide it by the total count.
=ROUND(SUM(VALUE(SUBSTITUTE([C1]@row, "%", "")), VALUE(SUBSTITUTE([C2]@row, "%", "")), VALUE(SUBSTITUTE([C3]@row, "%", "")), ................................................................................................................................................................................................, VALUE(SUBSTITUTE([C10]@row, "%", ""))) / 10) + "%"

Worked great! Thanks!
