## Percentage measure calculation keeps giving wrong answers

Hi all,

I have been struggling with a fairly simple calculation (I'm new in DAX, but experienced in Excel).

I am trying to measure whether client assessments within our business are being done on time.

Once the system opens the assessment, employees have 14 days to finish it. I therefore add 14 days to the starting date, being the due date. Then, once the assessment is completed, the finish date is logged. after the due date, the assessment becomes overdue.

To measure the timeliness on a monthly basis, I have produced status labels based on these conditions for the first day of the month.

When an assessment is not created yet OR open on 1 aug AND closed on time on 1 sep, I know that it was finished too late. I want to calculate the percentage of Assessments closed on time / Total assessments closed.

To do so, I have been trying the following formula to create a measure of the timeliness of August (i.e. 1 aug- 1 sep)

``````// proportion closed on time
(COUNTAX(FILTER('AssessmentData',
AND([Status 1 SEP 22]="Closed on time",
OR([Status 1 AUG 22]="Open on time",
[Status 1 AUG 22]="Non-existent"))),
'AssessmentData'[Status 1 AUG 22]))

//total closed
(COUNTAX(FILTER('AssessmentData',
AND([Status 1 SEP 22]="Closed on time",
OR([Status 1 AUG 22]="Open on time", [Status 1 AUG 22]="Non-existent"))),
'AssessmentData'[Status 1 AUG 22])
+
COUNTAX(FILTER('AssessmentData',
AND([Status 1 SEP 22]="Closed overdue",
OR([Status 1 AUG 22]="Open overdue",
[Status 1 AUG 22]="Non-existent"))),
'AssessmentData'[Status 1 AUG 22])
)``````

Help is MUCH appreciated. Thanks in advance!!
