Below are examples of how this data is calculated:

To calculate the YoY acquired revenue rate for December 2016 for a customer with a fiscal year that ends in June:

(Total given between July 2016 and December 2016 for constituents whose first gift (or first gift in the last 5 years) is between July 2016 and December 2016) /
(Total given between July 2015 and December 2015 for constituents whose first gift (or first gift in the last 5 years) is between July 2015 and December 2015)


To calculate the YoY acquired revenue rate for January 2017 for a customer with a fiscal year that ends in June:

(Total given between July 2016 and January 2017 for constituents whose first gift (or first gift in the last 5 years) is between July 2016 and January 2017) /
(Total given between July 2015 and January 2016 for constituents whose first gift (or first gift in the last 5 years) is between July 2015 and January 2016)

Note that the total given number is based on the Revenue Type filter (committed/received) which is based on the gift types selected in Control Panel/Settings.
However, the criteria to determine a constituent’s first gift date (acquisition date) includes all gift types regardless of filter settings.
