Luckily, these deviances from the plan, such as cost variance, don’t have to sink a project. Point-in-time cost variance measures the cost variance in a single timeframe. By understanding cost variance and how to calculate it, you’ll be better equipped to manage it effectively.
Projection of final cost:-
- This can lead to other calculations, such as quality variance and labor variances.
- To find this out, we need the cousin of cost variance, the schedule variance.
- It provides information on whether you are over or under budget in dollar terms.
The cost variance formula is a project cost management tool that can help you keep projects under budget. “Cost variance” is the difference between the expected cost of the project (or the amount budgeted) and the actual cost of the project (or the amount spent). When this value is positive, it indicates that a project is under budget, while a negative variance indicates that a project costs more than what you budgeted. In project cost management, if you are spending a specific number of dollars on your project, you are earning those dollars back into your project. Hence, every activity earns value that’s contributed to your project. The main formulas in the project cost management knowledge area include cost variance, schedule variance, cost performance index, and schedule performance index.
How to calculate Earned Value (EV) in project management
And by following the protips for containing cost variance and learning from real-world examples, you’ll have a better chance of keeping your projects on track and on budget. As you’ve learned in this blog post, cost variance is a crucial aspect of project management that can significantly impact your project’s success. It’s simply the difference between the actual cost of a project and the budgeted or planned cost. It’s usually expressed as a percentage or a monetary value and can be either positive or negative. Management of these project components will help reduce costs and control potential variance between expected and actual costs. Planning carefully and establishing policies and procedures for management will help in this area.
How to calculate cost variance in project management
Hence, the project’s Cost Variance is –20,000 USD, and you are over budget since it is negative. Find the project’s Cost Variance (CV) and determine if you are under budget or over budget. Please note that the Planned Value is not specifically given in the question, but the question says that half of the time has passed. In such a situation, you can assume that the budget was evenly distributed, so the planned value will be 50%. Find the project’s Schedule Variance (SV) and determine if you are ahead or behind schedule.
Therefore, variances should be analyzed when the expected savings from investigating them are greater than the expected cost of performing the investigation. Management should accept variance as a rule rather than an exception. The probability that actual quantities and prices will exactly match the standard is very remote.

This variance is the compilation of the production expense information. The causes of this variance include outsourcing, changes in supplier pricing, or account misclassification resulting in accounts not appearing. Ready to apply your CV formula and Project Cost Management knowledge to some sample PMP exam questions?
All three methods use the same formula, but they apply the calculation differently in order to determine different things. A WBS can also serve as a guide for a cost breakdown as it includes 100% of the project-related work. You find out that you have spent only $40,000 because you opted to buy some of the furniture at the local thrift stores.
You need contingency plans to keep the project on the right track even if conditions such as costs change. Take control of your team’s negative cost variance workload and achieve better project results with Plaky. There are only 2 weeks left to the deadline, and the budget is running out.
The budgeted cost of work performed is also referred to as earned value. Cost Variance is a simple concept and can be used to avoid cost overruns while managing a project. In this article, I will explain what cost variance is and why it can be useful. A blown budget or cost oversight can kill an otherwise good and viable company faster than anything else. You can see from the above that the formula is what we described in the opening section, it is simply the difference between what we had planned to earn or spend vs. what we have actually spent. Here you manage changes related to project management plans, processes, and baselines.

It is the difference between the actual quantity purchased and standard quantity, multiplied by Standard Cost per unit. For example, favorable prices on materials and good quantity variance indicate that the purchasing and production departments are using materials in a very efficient way. Therefore, all significant variances should be investigated, and corrective actions should be taken to find out why the variance occurred. When teams have clarity into the work getting done, there’s no telling how much more they can accomplish in the same amount of time. Everyone assumes that their brain is a static organ, and that recall only goes downhill with age.
