Revit formulas used in schedules are very powerful when organizing and presenting project data. Schedules can be used to display a variety of information about a project, including quantities, materials, and other important details. One of the most useful features of schedules is the ability to use calculated values. In this blog post, we’ll explore the benefits of using calculated values in schedules and provide some best practices for working with this feature in Revit.
Keep reading as at the bottom of this article we will show you a schedule of values example. We’ll demonstrate the workflow of how to create parameters for Area.
As a BONUS, we’ve also prepared a Window Revit Schedule you can download and use for free. Isn’t that great!? It looks like that:

But before that, let’s explore more about Revit Formulas, Calculated Values in Schedules, and all the benefits of using them.
What are Revit Formulas and Calculated Values in Schedules?
You can use Revit Formulas to calculate values based on other data in the schedule. For example, you might use a calculated value to determine the total area of all the walls in a project or the total cost of a set of materials.
The Benefits of Using Calculated Values
There are several benefits to using calculated values in schedules. The most obvious is that it saves time and reduces errors. Rather than having to calculate values for each item in the schedule manually, you can set up a formula to do the work for you.
Another benefit of using calculated values is that it allows you to generate more meaningful data. By performing calculations on data within the schedule, you can analyze the project and make more motivated decisions. For example, you might use a calculated value to determine the percentage of a particular material used in the project or the total number of light fixtures needed for a space.
An important benefit is an option to save the schedule as a form with calculated values to reuse in the next projects.
Best Practices for Using Calculated Values
While the benefits of using calculated values in schedules are clear, there are some best practices to keep in mind to ensure that you use this feature effectively.
Plan ahead
Before setting up calculated values in a schedule, it’s important to plan out what data you want to calculate and how you want to present it. This will help ensure that your calculations are accurate and that your schedule is organized and easy to read.
Use clear naming conventions
When setting up calculated values, be sure to use clear and concise naming conventions. This will make it easier to understand what each value represents and help prevent confusion. It is also very important to keep an eye on the units and precision used in the formulas.
Test your Revit formulas
It’s always a good idea to test your formulas before finalizing a schedule. This will help ensure that your calculations are accurate and that there are no errors in your formulas.
Use comments
If you have a complex formula that is difficult to understand, consider adding comments to your schedule. This will help ensure that others can understand your calculations and make it easier to troubleshoot any issues that arise.
Update your Revit formulas as needed
If the data in your schedule changes, it’s important to update your formulas accordingly. This will help ensure that your calculations remain accurate and that your schedule is up-to-date.
Revit Formulas: Schedule of Values Example
Let’s explore the step-by-step process of how to create a calculated value parameter for the schedule to calculate a window area.
- Schedule – Add calculated Parameter
- Type Parameter Name -Window Area (sq.m.)
- Select – Formula
- Discipline = Common
- Type = Area
- Formula = Width*Height
- Click – Ok
This should be the result after creating the parameters for the area
Another schedule of values example is how to create parameters for cost per sq.m. and VAT
In the end, we included 3 Calculated Parameters that are showing the area – Cost, Cost with VAT, and Totals. And these are the results shown in our window schedule:
