This guide walks through how to set up a basic headcount plan—starting with integrating your data, then building out department-level headcount, and planning for future hires.

​
Step 1: Set up your employee database

The first step is getting your employee data into Runway. The recommended approach is to connect to one of our available HRIS integrations. See our guides here for our most common HRIS integrations. Headcount Step1 Database Pn If you don’t have a supported integration available, there are two alternative options:
  • Google Sheets: Export your employee data to a sheet and connect it to Runway. See our setup guide here. If you go this route, make sure the sheet is kept up to date, as Runway will reflect whatever data is in the connected Sheet.
  • Manual setup: You can also create a standalone database directly in Runway with no external data source.
Once your database is created, make sure to populate key fields like Start date, Termination date (if applicable), and any dimensions you want to use for breakdowns—like Department, Role, or Location. For example, if you want to build headcount by department, ensure the Department dimension is included for each employee record.

​
Step 2: Create headcount drivers

  1. Create a headcount driver in a model Whether in a new model or existing one, select + Add Driver and create one called Headcount. Headcount Step2 Create Driver Pn
  2. Expand Headcount driver by the appropriate dimension Right click on the new Headcount driver and, within the dropdown menu, navigate to Dimension → Expand by Dimension, then select the dimension you’d like to segment Headcount by; in this example, we’ll use Department. Headcount Step2 Expand Pn
Expand by Dimension is a feature that should only be used with Headcount planning.It does not automatically created as drivers in a model when new attributes are added to a dimension and, thus, is not ideal for dimensions that are more dynamic.
If you have multiple dimensions with the same name, be sure to select the one coming from your HRIS data source.

​
Step 3: Build the formulas

  1. Build the headcount formula for one of the drivers Double-click into the forecast formula cell of the first dimensional driver and type count() to leverage the built-in count function.Step 4: Add new employees. Headcount Step3 Count Formula Pn Within the parentheses, type search to find your Employee database—if derived from an HRIS integration, it will be called Employee, by default. Now, we’ll set several filters on this database pill, essentially transforming it into a countIF(). Under filters, select the following:
    • Department (or your chosen dimension) is *This* Department - This is saying that for every Headcount driver with a dimension attribute on it, Runway will filter this same attribute for the formula.
    • Start date is on or before This Month
    • Termination date is on or after This Month
    Headcount Step3 Count Formula Filters Pn The date filters will provide us with rolling count of employees who are currently employed in any given month. When all is functioning as it should, you’ll be able to drill in and see each employee that’s rolling into said Department and the month in which they started or were terminated.
  2. Copy and paste the created formula for the rest of the headcount drivers Because both the drivers and the formulas are referencing the same dimension (e.g. Department), the values will smart update to reflect the appropriate amounts.
  3. Sum your headcount Create a Total Headcount driver and sum your headcount in one of the following ways:
    • Sum new drivers - Double-click into the forecast formula cell and type sum to leverage the sum function. Within the parentheses, type Headcount. The first option you will see is Headcount [Department], which references the collective dimensional drivers that you just created. Headcount Step3 Sum Pn
    • Sum driver group - If you put your Headcount drivers into their own driver group (shift + select them cmd + G), you have the option to sum the group itself. Double-click into the forecast formula cell and type sum to leverage the sum function. Within the parentheses, search for the driver group name and scroll in the dropdown to the driver group section. This will sum every driver within this group except for the one you’re typing in. Headcount Step3 Sum Group Pn
    • Sum the database directly - If you find that you won’t be leveraging dimensions as much for your Headcount breakdown, you can always sum the database itself for a total. Follow the instructions in Step 4 but omit the Department filter and you’ll have a full count of your active employees. Headcount Step3 Sum Database Pn

Step 4: Add new employees

The easiest place to add new hires is directly in the employees database. Click + Add Item, and make sure to fill in the key dimensions used in your headcount formulas—typically Department, Start date, and (if relevant) Termination date. This ensures that your new employees are included in the headcount calculations. Headcount Step4 Add Employee Pn To double-check that the new employee is flowing through correctly, open your model, click the caret next to the headcount driver, and confirm that the new row appears in the breakdown.
