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.
Changes in activity are the only factors that affect costs. All units produced are sold (there is no ending finished goods inventory). When a company sells more than one type of product, the product mix (the ratio of each product to total sales) will remain constant. The components of CVP analysis are: Level or volume of activity. Unit selling ...
An important part of standard cost accounting is a variance analysis, which breaks down the variation between actual cost and standard costs into various components (volume variation, material cost variation, labor cost variation, etc.) so managers can understand why costs were different from what was planned and take appropriate action to ...
Theoretical framework of the model can be either cost theory or production theory. In a model based on the production theory, the volume of activity is measured by input volume. In a model based on the cost theory, the volume of activity is measured by output volume. Accounting technique, i.e. how measurement results are produced, can differ.
While (ABC) Activity-based costing may be able to pinpoint the cost of each activity and resources into the ultimate product, the process could be tedious, costly and subject to errors. As it is a tool for a more accurate way of allocating fixed costs into a product, these fixed costs do not vary according to each month's production volume.
The labor efficiency variance is (4500 - 5000) x $14 = $7000, where 5000 hours = 2.5 hours x 2000 units of output. This variance is favorable since the actual hours used are less than the standard hours allowed. This may be the result of efficient use of labor time due to automation or the use of improved production methods.
In variance analysis, direct material usage (efficiency, quantity) variance is the difference between the standard quantity of materials that should have been used for the number of units actually produced, and the actual quantity of materials used, valued at the standard cost per unit of material.
Activity-based costing (ABC) recognizes that, in modern factories, most manufacturing costs are determined by the amount of 'activities' (e.g., the number of production runs per month, and the amount of production equipment idle time) and that the key to effective cost control is therefore optimizing the efficiency of these activities. Both ...
