STUDENT NOTES ABSORPTION AND MARGINAL COSTING Accountants and managers require financial information for many different purposes. To help make such decisions, costs can be classified in different ways: direct or indirect (in relation to production product costs) fixed, variable or semi-variable (in relation to time period costs). The difference in the treatment of fixed and variable costs is often crucial in making these decisions. The way fixed and variable costs are treated can give substantially different valuations of stock and hence profits. Dividing costs into product costs or period costs is essential in considering cost elements in absorption and marginal costing. Product costs: can be identified with a product, e.g. direct wages and direct materials. can be charged against revenue in the period when the products to which they relate are sold. form part of the valuation of stock of finished goods and work-inprogress. Period costs are not included in the valuations of stock. vary with production. Period costs: are those associated with time as opposed to product, e.g. annual insurance. can be charged against revenue in the period in which they are incurred. are usually fixed over a period of time, e.g. annual rent. ABSORPTION AND MARGINAL COSTING (H) 1
Advantages of marginal costing Easy for non-accountants to understand and can be used with standard costing systems. Can be used in break-even analysis. Fixed costs are incurred over a period of time. Such costs are not therefore directly related to production and hence are not included in the valuation of stock. Profits calculations are more realistic because they are related to the time period during which they arise. Fixed costs are not carried forward from one accounting period to the next. Assists when choices have to be made between alternatives, and contribution (selling price variable costs) is a critical consideration. Pricing policy can be related to variable costs as fixed costs are deducted from total contribution. This can assist when making decisions regarding special orders. The unit cost is pre-determined. Problems arising from a variable fixed cost per unit are eliminated. Apportionment of overheads is required. Overhead apportionment is frequently calculated on a subjective basis of the relationship between fixed costs and departmental activity. Under or over-absorption of overheads is avoided. (See section on under and over-absorption of overheads). The procedures to deal with under or over-absorption of overheads takes place when the level of activity differs from the pre-planned level. Useful when a costing is required for a specific decision that management is considering. Advantages of absorption (total) costing Fixed costs are incurred as a natural part of production. As absorption costing includes all relevant production costs in valuing closing stock a more realistic profit figure can be calculated. In marginal costing losses can occur in periods when sales are low and total fixed costs are written off. If the goods are sold in a later period then a distortion in the profit figures may arise. 2 ABSORPTION AND MARGINAL COSTING (H)
Absorption costing gives better information for pricing products as it includes both variable and fixed costs. Marginal costing may lead to lower prices being offered if the firm is operating below capacity. Customers may still expect these lower prices as demand/capacity increases. Which method should be used? As both methods have advantages and disadvantages, the precise method to use will depend on specific circumstances and the nature of the product/business. Where the viability of a product is desired, marginal costing would be used. However, a firm with a long-maturing product, such as whisky, may decide absorption costing is the more appropriate method. Only one method will be used by a firm. Over and under-absorption of overheads In the first set of examples provided in this resource the problem of over and under-absorption of overheads has been avoided by assuming that the actual and normal or planned output are the same. This is an unrealistic assumption. Consider the following example. Normal/planned production level 8,000 units Normal/planned fixed overheads 40,000 Actual production 7,500 units Fixed cost per unit = 40,000/8,000 = 5 Cost charged to production = 7,500 5 = 37,500 Under-absorbed fixed cost = 40,000 37,500 = 2,500 This means that 2,500 less than the actual fixed cost has been charged to the finished products, thus this under-absorbed overhead must be deducted from the profit calculated.
