What is Schedule Variance in Project Management? Schedule variance is an indicator of whether a project schedule is ahead or behind. It is typically used within earned value management (EVM) to provide a progress update for project managers at the point of analysis.
What is cost variance?
The cost variance is defined as the 'difference between earned value and actual costs. (CV = EV – AC)' (PMI, 2004, p. 357) Sometimes this formula is expressed as the difference between budgeted cost of work performed and actual cost work performed. If the variance is equal to 0, the project is on budget.
What is CPI and SPI?
The Cost Performance Index (CPI) is defined as the ratio of Earned Value to Actual Cost, while the Schedule Performance Index (SPI) is defined as the ratio of cumulative Earned Value to cumulative Planned Value (PMI, 2000). Both CPI and SPI are traditionally defined in terms of the cumulative values.
What is SV and CV?
- Cost Variance (CV): The CV is the difference between the earned value of the work performed and the executed budget (Actual Cost). CV= EV-AC. - Schedule Variance (SV): The SV is the difference between the earned value of the work performed and the planned value of the work scheduled. SV= EV-PV.

Cost variance is important because it allows you to track the financial progression of your project. It is an indicator of how well you monitor and mitigate potential risks and how well you analyze data related to the project.
How is SPI calculated?
The SPI calculation easily displays how close the work is to progressing within the original schedule estimate. Using the formula SPI = EV / PV, the project manager will have a value of less than 1 (project behind schedule), of 1 (project on schedule), or greater than 1 (project ahead of schedule).
What is CPI schedule?
The Cost and Schedule Performance Indexes (CPI and SPI) are powerful metrics a project manager can use to monitor cost and schedule performance. CPI is calculated by dividing Earned Value by Actual Cost. CPI is an indicator of how efficiently project resources are performing relative to the project budget.

Cost variance is the difference of earned value and actual cost. Schedule variance is the difference of earned value and planned value. CV = EV - AC. SV = EV - PV. If cost variance is negative then the project is over budget.
What is the formula for SV?
To calculate SV, subtract your project's planned value (PV) from its earned value (EV): SV = EV – PV. You will also need to know the value of your project's planned budget at completion (BAC). If your SV is positive, your project is ahead of schedule.

What is cost variance?
Cost variance is the difference between the amount you budget for a project and the actual amount you spend completing the project. The technical definition is the difference between the Budgeted Cost of Work Performed (BCWP) and the Actual Cost of Work Performed (ACWP). It's a way to show how an expense line item, project or any budget is performing financially. Many industries use cost variance in a variety of ways, from reports to forecasts, depending on what they're trying to achieve. Here are some example of cost variance in relation to specific costs:
Why is cost variance important?
Cost variance is important because it allows you to track the financial progression of your project. It is an indicator of how well you monitor and mitigate potential risks and how well you analyze data related to the project. You can also evaluate your cost variance to make comparisons between the budget and actual cost throughout a project your team completes, giving you the opportunity to make improvements to your budget approaches that align with your goals. Another helpful aspect is that you can use historical data from similar projects to create a more accurate projection for the budget.
What is a negative cost variance?
Cost variances are negative, positive or zero. A negative cost variance happens when you overspend and go above your budget. A positive cost variance happens when you underspend and stay below your budget. A zero cost variance is when the amount you spend matches your budget exactly. Negative cost variances can indicate a business is overspending and whether the business has enough excess funds to cover its overspending. Positive cost variance can indicate both effective and unsuccessful activities, and zero cost variances are ideal.
Why do project managers use variance?
Project managers often use cost variance to track where their actual costs stand compared to their budget. They use cost variance to make financial adjustments throughout the duration of the project. Cost accountants also use cost variance to track, investigate and report the reasons for a variance. They often give these reports to management along with suggestions for future changes to reduce or increase the size of the variance in the future.
Why do direct product costs change?
Direct product costs: Direct product costs can change unexpectedly due to product damage, delays in handling, an industry shortage of an item or an increase in shipping fees.
What is cost variance?
Cost Variance (CV): This is the completed work cost when compared to the planned cost. Cost Variance is computed by calculating the difference between the earned value and the actual cost, i.e. EV – AC. As you can deduce from the formula, Cost Variance will be negative for projects that are over-budget. Monitoring project cost variance is critical to ensuring the project is delivered on budget. Using realistic project estimations is a good start to ensuring there isn’t significant cost variance.
What is schedule variance?
Schedule Variance (SV): This is the completed work when compared to the planned schedule. Schedule Variance is computed by calculating the difference between the earned value and the planned value, i.e. EV – PV. A positive Schedule Variance tells you that the project is ahead of schedule, while a negative Schedule Variance tells you the project is behind schedule. Monitoring Schedule Variance is critical to delivering the project on-time.
What does negative cost variance mean?
Interpretation: Since the Project Cost Variance is negative, this means the project is over-budget. Since Schedule Variance is negative, the project is behind schedule. This example project is in major trouble and corrective action needs to be taken to get it back on track. Earned Value Management cost variance and schedule variance will help you identify a project in trouble. To fix the problem areas is a different ball game. You will need to use effective risk management. In this case, the project schedule variance can be controlled by using the critical path method.
Is schedule variance positive?
Since Schedule Variance is positive, the project is ahead of schedule. However, this has come at a cost of going over-budget. If work is continued at this rate, the project will be delivered ahead of schedule and over-budget. Therefore, corrective action should be taken in terms of cost.
