A cost variance percentage is the percentage over or under budget for a project is. The key is spotting them and making adjustments to stay on the right path. One of the best ways to avoid cost overrun is by calculating cost variance.
- You would use PV when your project progress does not correlate precisely to the percent of budget used.
- Okay, so now that we know what cost variance is, let’s discuss how to calculate it.
- It is another forecasting parameter that we can use to predict whether our project will end successfully or not.
- What matters, too, is how you look into what led to the cost variance of $1500.
- For example, the volume and price variances for direct materials are the material yield variance and the purchase price variance.
- If there is an extremely low cost variance (positive) or zero variance, they can take it as a sign of effective cost management.
A cost variance is the difference between an actual and budgeted expenditure. This variance is most useful as a monitoring tool when a business is attempting to spend in accordance with the amounts stated in its budget.

According to the PMBOK, this baseline is employed as a reference for the cyclical procedure of calculating project efficiency and development on the basis of schedule variance (SV) and cost variance (CV). The cost variance formula helps us determine the difference between the budgeted cost of work performed (BCWP) and the actual cost of work performed (ACWP). These parameters are also known as earned value (EV) and actual cost (AC). When project managers have this earned value analysis information, they can make the necessary adjustments to stay on track. If there is an extremely low cost variance (positive) or zero variance, they can take it as a sign of effective cost management.
