Cost variance (CV), also known as budget variance, is the difference between the actual cost and the budgeted cost, or what you expected to spend versus what you actually spent. This formula helps project managers figure out if they are over or under budget.

What is CV and SV in project management?
Cost Variance (CV): This is the completed work cost when compared to the planned cost.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.
How is CV calculated in project management?
Cost Variance can be calculated using the following formulas:
- Cost Variance (CV) = Earned Value (EV) – Actual Cost (AC)
- Cost Variance (CV) = BCWP – ACWP.
What is CV in EVM?
Advertisements. Cost Variance (CV) is a very important factor to measure project performance. CV indicates how much over – or under-budget the project is. CV can be calculated using the following formula: Cost Variance (CV) = Earned Value (EV) − Actual Cost (AC)
What is the cost variance of the project?
Cost variance is the process of evaluating the financial performance of your project. Cost variance compares your budget that was set before the project started and what was spent. This is calculated by finding the difference between BCWP (Budgeted Cost of Work Performed) and ACWP (Actual Cost of Work Performed).
Is PV a BAC?
Planned value is the authorized budget you assign to an activity or work breakdown structure (WBS). The total PV is also known as performance measurement baseline (PMB), budget at completion (BAC), or more often as Budgeted Cost of Work Scheduled (BCWS).
How do you calculate CV SV?
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. Since PV is equal to AC, then CV=SV.
What does negative CV mean?
Cost Variance
Conclusion: Cost Variance (CV) is negative which means the project is over budget and Schedule Variance (SV) is negative that means the project is behind the schedule.
What is SPI and CPI in project management?
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 50 50 rule in project management?
A related rule is called the 50/50 rule, which means 50% credit is earned when an element of work is started, and the remaining 50% is earned upon completion.
How do you calculate PV EV and AC?
Calculating earned value
Earned value calculations require the following: Planned Value (PV) = the budgeted amount through the current reporting period. Actual Cost (AC) = actual costs to date. Earned Value (EV) = total project budget multiplied by the % of project completion.
What is project variance?
A variance is defined as a schedule, technical, or cost deviation from the project plan. Variances should be tracked and reported, as well as mitigated through corrective actions.
How do you calculate cost schedule?
Cost schedule index (CSI)
It’s calculated as: Cost Schedule Index (CSI) = Cost Performance Index (CPI) x Schedule Performance Index (SPI) CSI = CPI x SPI.
How do you calculate a project?
Break down the project into activities and then further into smaller tasks, then estimate each task. Take a look at similar projects you’ve done in the past and how many hours they took. Then calculate the average. For example, project one took 5 hours and project two took 10 hours.
How do you calculate EV in project management?
You can calculate the EV of a project by multiplying the percentage complete by the total project budget. For example, let’s say you’re 60% done, and your project budget is $100,000 — your earned value is then $60,000.
What is cost variance CV?
Cost variance (CV), also known as budget variance, is the difference between the actual cost and the budgeted cost, or what you expected to spend versus what you actually spent. This formula helps project managers figure out if they are over or under budget.
What is the formula for blood alcohol content?
The simplified version of the Widmark formula is: BAC = [Alcohol consumed in grams / (Body weight in grams x r)] x 100. In this formula, “r” is the gender constant: r = 0.55 for females and 0.68 for males.
What does it mean if CV is positive and SV is negative?
SV is positive and CV is negative: The project is ahead of schedule but over budget. In other words, more tasks have been performed than were scheduled at this point, but the tasks that have been performed are over budget. SV is negative and CV is positive: The project is under budget but behind schedule.
Is Positive schedule variance good?
A negative schedule variance (SV < 0) indicates that the project is behind the schedule, as earned value does not meet the planned value. A positive schedule variance (SV > 0) indicates that the earned value exceeds the planned value in the reference period(s), i.e. the project is ahead of the schedule.
How do you calculate 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 budget at completion?
Budget at Completion (BAC) is a measure that is often used in earned value management to track the actual cost of a project against its forecasted budget. It is calculated at the start of a project based on the project work and its individual components.
