Schedule Variance Calculator


In project management, keeping track of schedule variance is crucial for ensuring that tasks are completed on time. A Schedule Variance Calculator simplifies this process by providing a quick and accurate way to determine the variance between planned and actual progress. This article will guide you through the usage, formula, example solve, frequently asked questions, and a conclusion regarding the Schedule Variance Calculator.

How to Use:

To utilize the Schedule Variance Calculator, input the planned and actual values of a project’s progress. Click the “Calculate” button, and the tool will provide the schedule variance, indicating whether the project is ahead or behind schedule.


The Schedule Variance (SV) is calculated using the following formula:



  • SV is the Schedule Variance
  • EV is the Earned Value (actual progress)
  • PV is the Planned Value (planned progress)

Example Solve:

Suppose a project has a planned value (PV) of 500 and an earned value (EV) of 450. Using the formula, the Schedule Variance (SV) would be:


This negative value indicates that the project is behind schedule by 50 units.

Frequently Asked Questions:

Q1: How is Schedule Variance interpreted?

A1: Schedule Variance represents the deviation between planned and actual progress. A positive SV indicates being ahead of schedule, while a negative value signals a delay.

Q2: Can Schedule Variance be zero?

A2: Yes, a Schedule Variance of zero means that the project is precisely on schedule, with actual progress aligning perfectly with the planned values.

Q3: How frequently should Schedule Variance be calculated?

A3: It’s recommended to calculate Schedule Variance regularly, such as at the end of each project phase or milestone, to identify and address potential issues promptly.


In project management, the Schedule Variance Calculator proves to be an invaluable tool for assessing project progress. By understanding and interpreting the variance between planned and actual values, project managers can make informed decisions to keep projects on track.
