Variance analysis can be carried out for both costs and revenues. Variance analysis is usually associated with explaining the difference (or variance) between actual costs and the standard costs allowed for the good output. For example, the difference in materials costs can be divided into a materials price variance and a materials usage variance.
Here’s an example. The ABC Company makes widgets. The company has fixed costs of $10,000 per month. Each widget costs the company $3.00 to make, and it sells each widget for $5.00.
Along with variable costs, fixed costs make up one of the two components of total cost: total cost is equal to fixed costs plus variable costs. In accounting and economics, fixed costs, also known as indirect costs or overhead costs, are business expenses that are not dependent on the level of goods or services produced by the business. They ...
For Example: if the railway coach company normally produced 40 coaches per month, and the fixed costs were still $1000/month, then each coach could be said to incur an Operating Cost/overhead of $25 =($1000 / 40). Adding this to the variable costs of $300 per coach produced a full cost of $325 per coach.

According to the PMBOK (7th edition) by the Project Management Institute (PMI), Cost variance (CV) is a "The amount of budget deficit or surplus at a given point in time, expressed as the difference between the earned value and the actual cost." [19] Cost variance compares the estimated cost of a deliverable with the actual cost. [20]
Realized variance or realised variance (RV, see spelling differences) is the sum of squared returns.For instance the RV can be the sum of squared daily returns for a particular month, which would yield a measure of price variation over this month.
In this way, ABC often identifies areas of high overhead costs per unit and so directs attention to finding ways to reduce the costs or to charge more for more costly products. Activity-based costing was first clearly defined in 1987 by Robert S. Kaplan and W. Bruns as a chapter in their book Accounting and Management: A Field Study Perspective ...
