You are a data analyst for a retail company. The model in Power BI Desktop contains a Sales table with an existing [TotalSales] measure and a Date table that is already marked as a date table. Your manager wants a new measure that shows the percentage change in sales versus the same period one year earlier (for example, March 2025 compared with March 2024). You open the Quick Measures dialog to avoid writing DAX manually. Which calculation template should you choose from the Select a calculation drop-down list?
The Year-over-year change quick measure is designed specifically for time-intelligence comparisons between the current period and the same period in the previous year. It automatically calculates (Current value - Prior-year value) ÷ Prior-year value, returning the percentage change.
Percentage difference from filtered value compares two arbitrary filter contexts rather than calendar periods. Year-to-date total accumulates values from the start of the year to the current date but does not compare across years. Rolling average smooths results over a moving time window and also does not perform a prior-year comparison.
