 description: "Formulas are the backbone of your model in Runway. They define the logic behind every driver and are essential for simulating how your business will evolve over time."

 ## Where to write formulas in Runway

 ### #1 Driver table blocks
 
-When working in a [driver table block on a page](https://docs.runway.com/concepts/pages/drivers-table-block) or in a [model](https://docs.runway.com/concepts/models/models-basics), you’ll often write or update formulas for the drivers you see there.

-Keep in mind that a driver table block can contain drivers created directly in the block, pulled from other driver table blocks, or drivers originating from databases. Given drivers are portable, making edits to the formula in one place will change it in all places it’s used.

 - **Show formulas as columns.**
 
-  Use the Customize menu to show the actuals and forecast formula columns, or press:
-  - `Option` \+ `Shift` \+ `A` to toggle the **actuals formula** column
-  - `Option` \+ `Shift` \+ `F` to toggle the **forecast formula** column
+  Use the Customize menu to show formula columns in the table:
+  - **Formula** column — displays the row-level formula that applies to each driver row, showing how formulas vary across different dimension values
+  - **Actuals Formula** column — shows the actuals formula for each driver (toggle with `Option` \+ `Shift` \+ `A`)
+  - **Forecast Formula** column — shows the forecast formula for each driver (toggle with `Option` \+ `Shift` \+ `F`)
+
+    The Formula column is particularly useful for understanding how formulas are applied across segmented data. When a row has multiple dimension values, the Formula column displays the formula with conditions that match those specific segments. For rows representing aggregated data (like "ANY" segments), you'll see formulas with `ANY` values in italics, indicating they apply broadly across that dimension.

 ## Forecast v.s. actuals formulas

+  Now that we've explored the different places where you can interact with formulas in Runway, let's look at another key concept: the distinction between **forecast** and **actuals** formulas.
 
   Every driver in Runway supports two formulas:
   - **Actuals formula** — used for all months **up to and including** your [last close date](https://docs.runway.com/concepts/last-close).
   - **Forecast formula** — used for all months **after** the last close.
 
   This split allows you to clearly separate how historical values are calculated from how future assumptions are modeled.
 
-  If an **actuals formula is not explicitly set**, Runway will automatically fall back to using the **forecast formula**. This fallback behavior follows Runway’s [formula inheritance logic](https://docs.runway.com/concepts/drivers/drivers-basics#formula-inheritance).

 ## Time period rollups (quarter, year, etc)
 
 ### Selecting the time period
 
 By default, data in a driver table block is displayed monthly, with each **month as a separate column**. But what if you want to see your drivers in a different time granularity—like by quarter or year?
 
 1. Click **Customize** in the top right, then select **Rollups**.
