Daily DAX : Day 423 FV

DAX Function: FV (Future Value)

The FV function in Power BI DAX calculates the future value of an investment based on periodic, constant payments and a constant interest rate.

Syntax

FV( <rate>, <nper>, <pmt>, [pv], [type] )

Parameters

Parameter Description Required?
rate Interest rate per period (e.g., 5%/12 for monthly) Required
nper Total number of payment periods Required
pmt Payment made each period (usually negative for outflows) Required
[pv] Present value (initial investment). Default = 0 Optional
[type] 0 = payment at end of period, 1 = payment at beginning. Default = 0 Optional

Common Use Cases

  • Calculate how much a savings plan or retirement contribution will be worth in the future
  • Financial modeling and forecasting in Power BI reports
  • Compare different investment or savings scenarios
  • Analyze loan maturity values (if additional payments are made)

Practical Examples

Example 1: Monthly savings of $500 for 10 years at 6% annual interest (compounded monthly)
Future Value = FV(6%/12, 10*12, -500) → Returns approximately $83,201.09
Example 2: Initial investment of $10,000 + $200/month for 5 years at 7% annual rate
Future Value = FV(7%/12, 5*12, -200, -10000) → Returns approximately $26,326.70

DAX Measure Example in Power BI

Projected Retirement Balance = FV( [Annual Interest Rate]/12, [Years Until Retirement] * 12, -[Monthly Contribution], -[Current Balance], 0 )

Tip: Use negative values for pmt and pv because they represent cash outflows from the investor's perspective.

FV is one of the key financial functions in DAX (along with PV, PMT, RATE, NPER) — perfect for building financial dashboards and investment trackers in Power BI.

Daily DAX : Day 131 SELECTEDMEASURE

 The SELECTEDMEASURE function in Power BI's DAX (Data Analysis Expressions) language is a powerful tool used primarily within calculation groups to dynamically reference the measure currently being evaluated in a report. It’s part of the calculation group feature introduced to streamline complex reporting scenarios and improve maintainability by reducing the need to duplicate measure logic. What is SELECTEDMEASURE? SELECTEDMEASURE is a DAX function that returns a reference to the measure that is currently active or "selected" in the context of a calculation group. It doesn’t take any arguments and is typically used in the expression of a calculation item within a calculation group. This allows you to write generic logic that can dynamically apply to whichever measure is being evaluated in a visual, without hardcoding specific measure names. Syntax SELECTEDMEASURE()     Returns: A reference to the measure currently being evaluated in the report context. Use Case SELECTEDME...

Daily DAX : Day 446 INFO.CSDLMETADATA

Power BI DAX Function: INFO.CSDLMETADATA INFO.CSDLMETADATA` is a specialized DAX function introduced as part of a broader set of "INFO" functions (like `INFO.TABLES` or `INFO.MEASURES`) used for **model introspection**. It allows you to programmatically access the underlying structure of your Power BI semantic model. What does it do? The function returns a table with a single column containing the Conceptual Schema Definition Language (CSDL)  metadata of your model in XML format . In plain English, it exports a highly technical "blueprint" of your entire data model—including tables, columns, relationships, and measures—as a structured XML string. It is essentially the DAX equivalent of the `DISCOVER_CSDL_METADATA` Dynamic Management View (DMV) used in Analysis Services. --- Syntax and Output The syntax is straightforward as it requires no arguments: ```dax EVALUATE INFO.CSDLMETADATA() ``` Return Value : A table with one column and one row. Content : A long string ...

Daily DAX : Day 453 ENDOFWEEK

Power BI DAX Function: ENDOFWEEK Description The ENDOFWEEK function is a Time Intelligence function in DAX (Data Analysis Expressions) used in Power BI. It returns the date that represents the end of the week containing a specified date (typically Saturday, as weeks are considered to start on Sunday by default in DAX time intelligence). Syntax ENDOFWEEK( [, ]) : A column reference (usually from a Date table) or a date expression. Required. : Optional. Specifies the week-ending convention. Default is Saturday if omitted. Examples 1. Basic usage (default: week ends on Saturday): End of Week = ENDOFWEEK('Date'[Date]) For a date like January 8, 2026 (Thursday), this would return January 10, 2026 (Saturday). 2. In a measure for cumulative sales up to end of week: Total Sales to End of Week = CALCULATE( SUM(Sales[Amount]), DATESBETWEEN('Date'[Date], ST...
