# Set up calculation variables

Define the variables to be used:

- In formulas.
- As scheduled units in work breakdown structures.

You can define variables that differ from the units. But you can also link a variable to a unit.

### Steps

1. Go to **Project management and accounting** > **Setup** > **Advanced project management** > **Calculation variables**.
2. Click **New**.
3. In the **Variable** field, type a value.
4. In the **Description** field, type a value.

> [!NOTE]
> **Notes**
> 
> All variables must have the same length. If you, for example, use three characters for the first variable that you create, all variables must have a length of three characters.
