Calculating Month-to-Date (MTD) Sales with DAX

In data analysis, it is always good to know how you are performing on a month-to-date basis because this can give you great insight into how your business is doing. Today, we will be discussing how to achieve the calculation of MTD sales in Data Analysis Expressions (DAX) in Power BI or Excel.

What is Month-to-Date (MTD)?

Month-to-Date (MTD) indicates the time from the beginning of the current month to the current date. The metric assists companies in monitoring their performance during the current month, enabling them to make adjustments and strategic decisions on time.

The DAX Formula for MTD Sales

To get MTD sales, we employ the following DAX formula:

MTD_Sales = CALCULATE(

    SUM(Sales[SalesAmount]),

    DATESMTD(Date[Date])

)

Breaking down this formula:

CALCULATE: This is a function that changes the context in which data is being calculated. It enables us to apply filters and make calculations within a particular context.

SUM(Sales[SalesAmount]): This is where the formula adds up the sales amounts from the Sales table.

DATESMTD(Date[Date]): This function returns a table with a column of dates for the month-to-date. It trims the data to only include the dates from the start of the month through the current date.

Step-by-Step Guide

1. Have a Date Table: Your data model must have a date table with a sequence of dates. This date table must be associated with your sales table.
2. Make the MTD Sales Measure:
   • Launch Power BI Desktop or Excel.
   • Go to the Data or Model view.
   • Choose the Sales table.
   • Click on “New Measure” and type in the MTD sales formula shown above.
3. Visualize the MTD Sales:
   • Add a new report or dashboard.
   • Drop the MTD_Sales measure to the visual to show the sales for the MTD.
   • Add a visual, e.g., Card, table, or chart.
4. Advantages of MTD Sales Tracking
   • Real-Time Insights: MTD sales give you real-time insights into your business performance so that you can make decisions in a timely manner.
   • Monitoring Performance: Comparing MTD sales with previous periods or targets, you can track your progress and detect trends.
