Schedule Variance Calculator


About Schedule Variance Calculator (Formula)

A Schedule Variance Calculator is a tool used in project management to determine the difference between the planned progress and the actual progress of a project at a specific point in time. This calculation helps project managers assess whether a project is ahead of schedule or behind schedule, allowing for timely adjustments and effective project control.

Formula for Schedule Variance Calculation:

The formula for calculating schedule variance involves subtracting the planned progress from the actual progress:

Schedule Variance = Actual Progress – Planned Progress


  • Actual Progress: The actual amount of work completed or progress made in the project up to a certain date.
  • Planned Progress: The amount of work that was planned to be completed up to the same date based on the project schedule.

A positive schedule variance indicates that the project is ahead of schedule, while a negative schedule variance indicates that the project is behind schedule.


  1. Project Monitoring: Project managers use the Schedule Variance Calculator to regularly track and assess the project’s progress against the planned schedule.
  2. Performance Evaluation: The calculator helps evaluate project performance and identify areas where adjustments are needed to meet project milestones.
  3. Decision Making: Schedule variance calculations assist in making informed decisions regarding resource allocation, scheduling changes, and risk management.
  4. Client Communication: Project stakeholders can use schedule variance data to communicate project status and potential delays to clients or stakeholders.
  5. Continuous Improvement: Analyzing schedule variances contributes to continuous improvement in project planning and execution processes.

In summary, a Schedule Variance Calculator involves calculations that assist project managers and teams in evaluating the progress of projects compared to the planned schedule, facilitating proactive decision-making and ensuring successful project delivery.
