# MTD & MTD LY Calculation

So MTD is pretty basic and is working ok.

With my LY calculation i want to calculate up to the same day this year, even though i’m looking at the whole month of August. ie, it’s the 14th Today, i want to know what sales were up to the 14th August Last Year, the calc i’m using is giving me the whole month.

`Invoice Amount MTD LY = TOTALMTD ( [Invoice Amount] , SAMEPERIODLASTYEAR ( 'Date'[Date] ) )`

One solution i’ve seen is to reduce the calendar to only include days up until todays date, and this does work, but there has to be a better solution.

Any ideas?

Hi Benaud,

Have you seen this one?

I think this should get you the answer.

Let me know if not. Thanks

Brilliant… Thanks

Ok, So the solution in the video works when viewing the data by day, such as in the chart.

I wanted to use a series of cards to show the sales to date for the month vs the same day of the month last year and work out a percentage vs last year MTD.

I added 2 columns to my date table view from the DW.
Month2: contains the month name & year (Sep 2018), except for the Current Month which contains the text “Current Month”
DayDescr: Blank except for values for “Today” and “Yesterday”

``````Invoice Amount MTD LY =
IF (SELECTEDVALUE('Date'[Month2]) = "Current Month",
CALCULATE(
[Invoice Amount Same Mth LY],
FILTER('Date', 'Date'[DayDescr] = "Yesterday")
),
[Invoice Amount Same Mth LY]
)
``````

Invoice Amount Same Mth LY = TOTALMTD([Invoice Amount],DATEADD(‘Date’[Date],-1,YEAR))

I did the same calc for YTD too

Cool, is it actually working for you now? I was just about to start working on an example but actually looks like you might have it?

Let me know.
Thanks

got it working… thanks. probably better ways to do it, but i am a good hacker.

Hi
If I try to replace the dates with product group it stops working. How do I fix that?
