Whats the difference between 12 mtd , 12 mtd rolling and ytd calculation

+8  A: 

12 mtd goes back 12 months, whereas a ytd is from the first day of the current year (calendar, fiscal, whatever) to the current day.

What about 12 mtd rolloing ?
Tommy
To my mind, the "to-date" portion of mtd makes it rolling by definition.
Hank Gay
I agree, not sure what the difference might be between 12mtd and 12mtd rolling. One possibility is that a rolling average is what's being asked for in the latter case.

Example:

Today=20090318

REPORT TYPE - REPORT PERIOD


12MTD report - 20080401 to 20090318

YTD report - 20090101 to 20090318

In addition to Hank Gay's answer, a 12 mtd calculation is the same as a 12 mtd rolling calculation.

General, you would normally see a 3 mtd rolling, or 6 mtd rolling calcuations.
