Summary  
This chapter shows how to create DAX measures on the fly using Quick Measures (for example, running totals) and how to implement calculated columns for precomputed row-level calculations to improve performance.  

General domain of usage  
Business intelligence

Explore **Quick Measures** in Power BI to simplify complex calculations and create insights faster. You will also learn how to incorporate hard-coded calculations using **calculated columns** and understand how creating a **running sum** enhances data analysis and enables more dynamic visuals.

**Calculated columns** provide additional flexibility by allowing you to define custom logic at the row level, enriching your dataset with meaningful derived values.

Here’s an example of a DAX measure created using the **Quick Measures** feature to calculate a **running total** of riders:

```DAX
Total Riders Running Total in Date =
CALCULATE(
    [Total Riders],
    FILTER(
        ALLSELECTED('Date Table'[Date]),
        ISONORAFTER('Date Table'[Date], MAX('Date Table'[Date]), DESC)
    )
)
```
