Forecasted Cost at Completion (EAC):
Track Project Cost Overruns in Excel

Learn how to track Forecasted Cost at Completion (EAC) in Excel so you can spot budget drift before it turns into a bigger problem. In this lesson, you’ll see how to compare budgeted cost against projected final cost, summarize results by project manager, and build a simple visual to highlight which jobs are trending over or under budget.

How to Calculate Forecasted Cost at Completion (EAC) in Excel

1. Review the Key Columns in the Dataset

Before building the summary, make sure your dataset includes the core fields needed for the analysis:

  • Project start date
  • Project manager
  • Budget
  • Projected final cost

You may also have other useful fields like:

  • Job type
  • Location
  • Status
  • Market

The video emphasizes that clean data structure is what makes this KPI possible.

2. Create a Row-Level Overrun Check

To begin exploring the data:

  • Create a column that compares projected final cost against budget
  • Subtract the budget from the projected amount
  • Treat positive values as over budget
  • Treat negative values as under budget

This gives you a simple project-level check before building the summary table.

3. Filter for Projects Over Budget

Once the row-level overrun column is created:

  • Apply a number filter
  • Filter for values greater than zero

This quickly shows every project that is currently projected to finish over budget.

4. Create a Unique List of Project Managers

Next, build the summary section by project manager:

  • Add a PM column in the summary area
  • Use the UNIQUE function to pull a distinct list of project managers
  • Sort the list alphabetically for easier reading

This creates the structure for summarizing results by manager.

5. Add Budget and Final Cost Columns to the Summary Table

Set up the main columns in the summary section:

  • Budget
  • Final Cost

These columns will hold the aggregated totals for each project manager.

6. Sum Budget by Project Manager

Use the SUMIFS function to total the budget for each PM:

  • Sum the budget column
  • Match the rows based on the project manager name in the summary table
  • Copy the formula down for the full PM list
  • Format the results as currency

This gives you total budgeted cost by manager.

7. Sum Projected Final Cost by Project Manager

Repeat the same process for projected final cost:

  • Use SUMIFS again
  • Sum the projected final cost column
  • Match each result to the corresponding PM
  • Copy the formula down
  • Format as currency

Now you have both planned cost and projected cost summarized by manager.

8. Add an Over or Under Budget Dollar Column

Create a new column to compare the two totals:

  • Subtract budget from final cost
  • Copy the calculation down the table
  • Interpret positive values as over budget
  • Interpret negative values as under budget

This shows the projected dollar variance for each PM.

9. Add a Percentage Variance Column

To make the comparison easier across managers:

  • Create a percentage column based on the dollar variance relative to budget
  • Format the results as percentages
  • Copy the formula down

This gives you a normalized view of performance so managers can be compared more fairly.

10. Filter the Summary to Active Jobs Only

The video then refines the analysis to focus on current work:

  • Go back to the SUMIFS calculations
  • Add one more criteria for active jobs
  • Update both the budget and final cost summaries to include only active projects

This makes the KPI more useful for current decision-making instead of mixing in completed jobs.

11. Create a Quick Visualization

Once the summary table is complete:

  • Highlight the PM names and percentage variance column
  • Go to Insert and choose a recommended chart
  • Use whichever chart style best communicates the comparison
  • Link the chart title to a worksheet cell if you want faster editing
  • Add data labels to show the values directly on the chart

This gives you a clean visual of projected over or under budget performance by project manager.

12. Format the Final View

To finish the report:

  • Resize the chart as needed
  • Adjust the title
  • Add data labels
  • Consider changing the color of the series to make problem areas stand out more clearly

The result is a simple summary that helps you quickly see which managers are tracking above or below budget on active jobs.

Tracking Forecasted Cost at Completion (EAC) in Excel Dashboards

Q1. What is Forecasted Cost at Completion (EAC)?
Forecasted Cost at Completion, or EAC, is a project management KPI that estimates what a job is expected to cost by the time it is finished. It helps HVAC companies and project-based businesses identify cost overruns early, before they become year-end surprises.

Q2. Why is EAC important for project management?
EAC helps project managers and business owners monitor whether jobs are staying on budget as work progresses. Instead of waiting until the project is finished, you can use this KPI to catch small cost overruns early and take corrective action sooner.

Q3. How do I track Forecasted Cost at Completion in Excel step by step?
You can organize your project data by budget, projected final cost, and project manager, then summarize the results to compare where each manager stands. From there, you can create a simple chart to visualize which projects or teams are trending over or under budget.

Q4. Can this KPI be analyzed by project manager or job type?
Yes. One of the biggest advantages of tracking EAC in Excel is that you can break it down by project manager, job type, market, or other categories in your dataset. This gives you a clearer picture of where budget drift is happening and which areas need attention.

Q5. What does it mean when a project is over or under budget?
If a project’s projected final cost is higher than its budget, it is trending over budget. If the projected final cost is lower than the budget, it is trending under budget. This comparison helps teams quickly understand which jobs may be creating margin risk.

Q6. What’s the best way to visualize EAC results in Excel?
A simple bar or column chart works well for comparing EAC percentages across project managers or job categories. This makes it easier to see who is managing projects efficiently and where cost control issues may be developing.
