DESCRIPTION

Managing costs accurately is crucial for any successful project, and Primavera P6 offers powerful features to help you do just that. One essential option is Recalculate Assignment Cost, which ensures your activity costs always reflect updated resource rates or units. In this article, we’ll walk you through why this option matters, when to use it, and how to apply it step by step.

Why Is Recalculating Assignment Cost Important?

When you update your resource or role cost information—such as changing hourly rates or daily working hours—Primavera P6 doesn’t automatically adjust the assignment costs for activities. Without recalculating, your project’s total budget and actual cost data can become inaccurate, leading to flawed forecasts and reporting errors.

Using the Recalculate Assignment Cost option ensures that every change in resource cost information immediately reflects in your project’s budgeted costs across all open projects. This helps maintain financial accuracy and control over your project.

Step-by-Step Guide to Recalculating Assignment Cost

1️⃣ Open Your Project

Start by launching Primavera P6 and opening the project you want to update. This tutorial uses Primavera P6 version 20.12, but the steps are similar across other versions.

2️⃣ Update Resource Information

Navigate to the Resources window. Here, you can update the unit prices, maximum units per time, or standard rates for each resource. For example, if your labor cost per hour increases from $150 to $300, update the Standard Rate field.

3️⃣ Locate Assigned Activities

Go to your Activities window and identify where the updated resource is assigned. This helps you see which tasks will be affected by your changes.

4️⃣ Use Recalculate Assignment Cost

Once your resource updates are complete, go to the Tools menu and select Recalculate Assignment Costs. Confirm your choice when prompted. Primavera will automatically update the activity costs based on your revised resource information.

5️⃣ Review Updated Costs

After recalculation, check your Activities and Resources windows to confirm the total budgeted costs have changed accordingly. For example, if you reduced a resource’s working hours from eight to six hours per day, the total cost for activities using that resource will decrease after recalculating.

Tips & Common Mistakes

Always recalculate assignment costs after each resource update to avoid outdated budget figures.
Skipping recalculation leads to incorrect total costs, which can cause significant budgeting errors.
Remember, it’s not mandatory to change every parameter; updating either standard rate or maximum units alone may be enough, depending on your project needs.
Use resource filters in Primavera P6 to quickly isolate the resources you want to update and recalculate.

CONCLUSION

The Recalculate Assignment Cost feature in Primavera P6 is an essential tool for maintaining accurate project budgets. By understanding when and how to use it, you can ensure your project’s financial data is always reliable—helping you manage costs proactively and avoid unpleasant surprises at project closeout.
