Persistency in Tableau

Question

I am trying to calculate Persistency in Tableau report.

Persistency: This is a measure of how efficiently an adjuster (or claims office) is working through their claims. The calculation is simple:

Number of Claims, ( OPEN at Beginning of Month – OPEN at End of Month ) / (OPEN at Beginning of Month) as a Percent.

So if an adjuster has 100 open claims on 4/1, 10 new claims are opened in April, and adjuster closes/settles 40 claims, leaving 70 open on 4/30. Persistency = (100-70)/100 = 30%

I have datasheet with Claim Numbers and their respective "Date Of Report" as well as their "Close Date". I am confused how to proceed. Any help will be appreciated.

Answer 1

I hope the Data looks similar to this Data Structure

With this let us try to find the Open Claims for Previous month and Open claims for current month To find the previous open claims, I have used the following code

if 
MONTH([Current Date])<>MONTH([Report Date])
and
[Status]="Open" then 1 end

For current open claims

if 
MONTH([Current Date])=MONTH([Report Date])
and
[Status]="Open" then 1 end

Now, with this, let us try to calculate Persistency

(SUM([Previous Open Claims])-SUM([Current Open Claims]))/SUM([Previous Open Claims])

Hope this works! Please let me know if you have more clarification!
