Price Variance: What It Means, How It Works, How To Calculate It

This difference between earned value and
actual cost in this example is actually not insignificant. Calculating the
cost-performance index and determining the to-complete performance index can
help analyze this result and assess its impact on the overall project. The
cumulative CV is a measure for the cumulative difference of the cumulative earned
value and actual cost figures of several, usually consecutive, periods. Any of these categories can account for a spending variance, which is any expense that is different than was budgeted for such as direct materials, labor, or overhead.

However, in real life it’s likely they will be a little different because of how equipment and time is booked and paid for. The challenge for you as the project manager is to reconcile the variance with what is acceptable. For example, there should be tolerances set on the project so you know what is a reasonable amount of drift. The final tip we have for you is to continue forecasting your project’s cost performance until it is completed. A major part of project cost control includes establishing variance control thresholds. These are set amounts of variation that don’t require resolving or any corrective action.

Cost variance analysis definition

The project manager or company management analyst working on variance analysis looks for all these differences in expected and actual costs. This can lead to other calculations, such as quality variance and labor variances. It’s best to perform variance analysis reporting after a new cycle of operations begins. 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. The main formulas in the project cost management knowledge area include cost variance, schedule variance, cost performance index, and schedule performance index. To derive these values, a PM must also be able to calculate earned value, actual cost, and planned value.

  • If your budgeted (or expected) sales total was $1,000 and your actual sales total was $2,000, then your sales variance is -$1,000.
  • Instead of playing the guessing game with expenses, you can use the WBS to identify costs line by line.
  • This PMP exam and project management concept is necessary whether you are controlling costs for a project or preparing for the PMP exam.
  • Simply put, earned value is the monetary value of the accomplished work at a given point in time.
  • What do you do if the cost variance of your project points to overspending?
  • Cost variances can occur in any project, and they are sometimes inevitable or even impossible to prevent.

As this breakdown includes 100% of the work tied to the project in question, it can also serve you as a guide for a cost breakdown. A work breakdown structure (WBS) is just what it says it is — it is a breakdown of everything you need to do for the project to complete it. Unforeseeable circumstances can get the best of you, and if you haven’t already paid enough attention to the project’s financial performance — they can be your undoing. Other times, though, their cause may be your reliance on outdated data while creating estimates. As you can tell in the example, the project has been consistently missing the mark as far as the budget goes.

Favorable and Unfavorable Variances

The formula for fixed overhead variance is standard (or budgeted) overhead cost minus actual overhead cost. Both figures are overhead totals, so they encompass the total cost of all of your overhead expenses for a given period. You can calculate variance at completion by subtracting what you currently think the total project will cost (or forecasted cost) from what you originally thought the project would cost (the expected cost). Earned value, sometimes called planned value, represents the budgeted cost of work performed at a particular point in a project. Earned value management can help you check in on progress periodically and ensure your project is on track and on budget.

Finance – Cost variance formula

The following is a diagram of the flow of relationships of the different cost variances and how their calculation filters into total production costs. These knowledge areas group together the theories and techniques that make up the bulk of a project manager’s work. The 47 processes required for the PMP exam are spread out amongst the 10 knowledge areas. Cost variance falls under Project Cost Management, but the information required to calculate cost variance comes from multiple knowledge areas. Cost variance (CV) is a PMP exam concept that measures project progress against the project’s cost baseline. Calculating a CV will help you determine any variance from the project’s monetary budget.

Cause #4: Accounting mistakes

Throughout the life of a project, you’ll want to have each of these cost variance formulas at your disposal. Thankfully, there are cost management tools that make keeping your eye on variances effortless so that you don’t have to manually crunch the numbers. Such cost developments are not unusual
given that projects and teams may require some ‘settling in’ time before they can
leverage their full performance potential. For
instance, if you are in month 4 of a project, you would calculate the
point-in-time cost variance of that period by using the actual cost (AC) and
earned value (EV) of the 4th month only. Management of these project components will help reduce costs and control potential variance between expected and actual costs.

The variances that comprise the cost variance indicate that ABC saved money on purchasing steel (possibly because it was substandard steel), and lost money on the use of the steel. These two variances, when combined, give management valuable information for where to go to conduct its investigation of the total cost variance. Cost variance is the difference between earned value and actual cost, at the date you wish to measure. Staying within the project’s budget is a major concern for project managers. To ensure they don’t overstep their financial limitations and stay on track with their spending — they calculate the cost variance throughout the project’s lifecycle. In general, aim for a positive or favorable variance, as this indicates that the project is on track and within budget.

Labor variance can occur because of poorly set standards, variation in staffing, and changes in benefits. CBAs use ratios to determine the feasibility of the investment, and the net present value formula (NPV). As a potential PMP credential holder, calculating CV is just the first step. Interpreting your results is the next step and will tell you if you are over, under, or on budget. Their past experience should help them foresee all the minute expenses that may have to be added to the project.
