Retention Rate per Day given Customer Active and Eligible Days

[Oleksii]

Hi All!

I have a dataset of customers, how long have they been using our Subscription (Active Days) and how long ago they have taken that Subscription (Eligible Days)

Basically Active = 1 Eligible = 10 means that Customer has subscribed 10 days ago and Canseled on his first day.

Customer_ID	Active Days	Eligible Days
1	1	10
2	10	50
3	7	20
4	15	15

Is there a way I can plot a chart like this?

e.g.  - whats the % of customers that have retained each day after Subscription was taken, regardless of the actual Start Date?

Thanks in advance!

Hi,

I think i can solve this problem provided the following columns are present in your dataset - ID, Date of subscription and Date of churn.

Please share your dataset.

So, for the sample data provided, which day in your axis would each of those 4 items drop off?

[Oleksii]

Each of the customers drop of at their "Active Days" +1
The chart would look like:

Day 1 - 100% - 4 out of 4 Customers survive day 1

Day 2 - 75% - first customer dropped off (3 / 4 = 75%)

Day 3 - 75% - no changes

...

Day 7 - 75% - no changes

Day 8 - 50% - one more customer dropped off (2 / 4 = 50%)

and so on

Kind of looks like a Kaplan Meier Survival Curve:

I understand this approach, but it's a bit now that I'm looking for.

I'm my case my data table also has all kinds of User Attributes, and I would love to use those Attributes as filters / legend on the "survival" chart.

OK, I came up with the following. Create a table like this:

Days = GENERATESERIES(1,30,1)

And then a measure like this:

Measure = 
    VAR __CurrentDay = MAX('Days'[Value])
    VAR __All = COUNTROWS('Table')
    VAR __Survivors = COUNTROWS(FILTER('Table',[Active Days] + 1 > __CurrentDay))
RETURN
    DIVIDE(__Survivors,__All,0)

May need some tweaking. No reason it should not work with filters or legends. PBIX is attached.

This is great!
Thank you so much!

@Oleksii , Not sure I got it. But you can plot active days on-axis.
