Customer Loyalty

Hi,

In my model, I need to calculate customer loyalty.  for example, Adam bought a service from us on 15 July 2016, recorded as service effective date and 15 July 2017 as service expiry date, and every year he renewed his service until 1 Jan 2020. I need to come up with a measure to show 3.5 years as Adam's loyalty. Please help me.

Hi @timazarj ,

 

Try the following formula:

 

Measure = 
CALCULATE(
    DATEDIFF(
        MIN('Table'[effective date]),
        MAX('Table'[expiry date]),
        MONTH
    ) / 12,
    ALLEXCEPT('Table','Table'[customer])
)
