Calculate percentage based on two dates duration and today's date

[Anonymous]

I have two dates: 

policy start date: 1/1/2023   

policy end date:  1/20/2023

Duration: 20 days 

todays date: 1/10/2023 (this date will change daily)

For policy start and end dates 1/1/2023 - 1/20/2023 (20 Days). If looking ar report on 1/10/2023, the duration of the policy 1/1/2023 - 1/10/2023 (10 days) is at 50%. 

If looking at the report on 1/11/2023, the duration will be 1/1/2023 - 1/11/2023 (11 days), which will be 55%. 

So this number will change every day depending on when you look at the report. 

I want the duration column to be shown in percentage. How would I write this?

Thanks,

Hi @Anonymous ,

Please try below steps:

1. create a measure with below dax formula

Measure =
VAR start_date =
    DATE ( 2023, 1, 1 )
VAR end_date =
    DATE ( 2023, 1, 20 )
VAR cur_date =
    TODAY ()
VAR _diff1 =
    DATEDIFF ( start_date, end_date, DAY )
VAR _diff2 =
    DATEDIFF ( start_date, cur_date, DAY )
RETURN
    DIVIDE ( _diff2, _diff1 )

2. add a crad visual with this measure

Please refer the attached .pbix file.

Hey thanks for the reply. What if  today's date (cur_date) is coming from a date filter. Is there a way to dynamically change that as the user chnages the date filter?
