# Calculate sum for specific period and difference between same period of previous year

How do I calculate revenue from one month to the same month in the previous year?

I have an ARR column and would like to calculate the sum for a particular period (e.g. Jan 2016) and calculate the difference in ARR between that period and the same period of the previous year (i.e. Jan 2017 vs Jan 2016).

 Executed Agreement Date ARR Amount 1/30/2017 1590.5 1/30/2017 381.72 1/12/2016 31.81 1/30/2016 2226.7

I also created another table with a datekey for dates between 2000-2030 and columns for year and month – in case that’s needed in a formula.

## Re: Calculate sum for specific period and difference between same period of previous year

Try the following

Assumptions:  The calendar table and the dataTable are linked on the date columns of respective tables.

You also have a column in Calendar Table for YearMonth

1. Create a measure called  ARRTotal = sum(datatable[ARRAmount]).

2. For Previous Year Same Period create the measure

ARRPrYr = Calculate([ARRTotal],SAMEPERIODLASTYEAR('Calendar'[Date]))

3. Now plot a Table visual with

a) YearMonth column from calendar table

b) Measure ARRTotal

c) Measure ARRPrYr

You should be able to see the result you expect.

If this solves your issue please accept this as a solution and also give KUDOS.
