## Total count in a period

Hi
I would like to count the total number of customers, so I can show that i 2019 we had 6 customers and in 2020 we had 7 customers and so on. Which function is the right one to choose for that?

I dosnt work for me to use DISTINCTCOUNT or TOTALYTD

My data looks like this.

 CustNumber CompanyName CreatedDate 98 Very Old Company 01-01-1983 99 Older Company 01-01-1993 100 Old Company 01-01-2003 101 Walmart Inc. (WMT) 01-08-2019 102 China Petroleum & Chemical Corp. (SNP) 01-09-2019 103 Amazon.com Inc. (AMZN) 01-10-2019 104 PetroChina Co. Ltd. (PTR) 01-04-2020 105 Apple Inc. (AAPL) 01-02-2021 106 CVS Health Corp. (CVS) 02-02-2021 107 Royal Dutch Shell PLC (RDS. A) 01-05-2022 108 Berkshire Hathaway Inc. (BRK. A) 01-06-2022 109 Toyota Motor Corp. (TM) 01-07-2022 110 Volkswagen AG (VWAGY) 01-08-2022

What I would like to show is:

 Year Total Number of Customers Created Net increase compared to last year 2019 6 2020 7 1 2021 9 2 2022 13 4

Thank you

Hi @LangeJan ,

Create the following two measures:

``````Cumulative customers = CALCULATE(DISTINCTCOUNT('Table'[CustNumber]), 'Table'[year]<= MAX('Table'[year]))

var cumulative =
[Cumulative customers]
- CALCULATE ( [Cumulative customers], 'Table'[year] = MAX ( 'Table'[year] ) - 1 )``````
