What Is Project Overrun Rate?

Project Overrun Rate represents the percentage increase in costs or duration beyond the initially estimated budget or timeline for a project within the realm of Professional Services Automation (PSA). It measures the extent to which a project exceeds its planned constraints.

In Professional Service Automation (PSA), the Project Overrun Rate refers to the frequency at which projects exceed their planned scope, budget, or timelines. This rate is a critical metric for evaluating the effectiveness of project management practices.

Importance of Project Overrun Rate in PSA

Project Overrun Rate serves as a critical indicator of project management efficiency and financial health. It highlights the magnitude of deviations from planned budgets or timelines, aiding in proactive measures to mitigate risks and enhance project delivery.

1. Cost Management: High overrun rates can significantly impact a firm’s profitability.

2. Client Satisfaction: Overruns often lead to client dissatisfaction and can harm the firm’s reputation.

3. Operational Efficiency: It’s a key indicator of the efficiency and accuracy of project planning and execution.

How to calculate Project Overrun Rate?

The formula to calculate Project Overrun Rate involves comparing the planned project value with the actual value and expressing the deviation as a percentage:

Project Overrun Rate = (Actual Project Value − Planned Project Value / Planned Project Value) × 100%

  • Actual Project Value encompasses all actual project costs or duration incurred during execution.
  • Planned Project Value refers to the initially estimated or planned budget or timeline.


Suppose a project was planned to cost $50,000 but ended up costing $60,000. Using the formula:

Project Overrun Rate(60,000−50,000/50,000)×100%=20%

Thus, the Project Overrun Rate for this project is 20%.

Project Overrun Rate vs Other Performance Metrics

Compared to metrics like cost variance or schedule variance, Project Overrun Rate specifically quantifies the percentage increase in costs or duration. While variance metrics highlight deviations from planned values, Overrun Rate emphasizes the relative magnitude of the overages.

1. Completion Rate: Focuses on the percentage of projects completed, regardless of overruns, while the overrun rate specifically measures deviations from original plans.

2. Resource Utilization: This metric assesses how effectively resources are used, unlike the overrun rate which measures adherence to project parameters.

Metric Definition Importance / Use
Project Overrun Rate Percentage by which a project exceeds its planned budget/timeline Indicates the extent of deviation from the planned project parameters
Schedule Variance Difference between planned project timeline and actual progress Indicates the deviation from the scheduled project timeline
Cost Variance Difference between actual project costs and budgeted costs Measures the variance between planned and actual project expenditures
Earned Value Measurement of project progress in monetary terms Evaluates the project’s progress in monetary terms based on work completed

Utilization of Project Overrun Rate in PSA

Analyzing Project Overrun Rate aids in assessing project performance, identifying underlying causes for overruns, and instituting corrective actions. It enables proactive measures to control costs and timelines, thereby improving project management practices.

1. Robust Project Planning: Using project management tools to develop realistic and comprehensive project plans.

2. Risk Management: Proactively identifying and managing potential risks that could lead to overruns.

3. Regular Monitoring and Reporting: Implementing effective tracking and reporting systems to monitor project progress and address issues promptly.
