ABSORPTION AND MARGINAL COSTING
ABSORPTION AND MARGINAL COSTING (H) 1
STUDENT NOTES
Accountants and managers require financial information for manydifferent purposes. To help make such decisions, costs can be classifiedin 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 oftencrucial in making these decisions. The way fixed and variable costs aretreated can give substantially different valuations of stock and henceprofits.
Dividing costs into product costs or period costs is essential inconsidering cost elements in absorption and marginal costing.
Product costs:
• can be identified with a product, e.g. direct wages and directmaterials.
• can be charged against revenue in the period when the products towhich they relate are sold.
• form part of the valuation of stock of finished goods and work-in-progress. 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. annualinsurance.
• can be charged against revenue in the period in which they areincurred.
• are usually fixed over a period of time, e.g. annual rent.

ABSORPTION AND MARGINAL COSTING (H)2
Advantages of marginal costing
• Easy for non-accountants to understand and can be used withstandard costing systems.
• Can be used in break-even analysis.
• Fixed costs are incurred over a period of time. Such costs are nottherefore directly related to production and hence are not includedin the valuation of stock.
• Profits calculations are more realistic because they are related to thetime period during which they arise. Fixed costs are not carriedforward from one accounting period to the next. Assists whenchoices 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 arededucted from total contribution. This can assist when makingdecisions regarding special orders.
• The unit cost is pre-determined. Problems arising from a variablefixed cost per unit are eliminated.
• Apportionment of overheads is required. Overhead apportionment isfrequently calculated on a subjective basis of the relationship betweenfixed costs and departmental activity.
• Under or over-absorption of overheads is avoided. (See section onunder and over-absorption of overheads). The procedures to dealwith under or over-absorption of overheads takes place when thelevel of activity differs from the pre-planned level.
• Useful when a costing is required for a specific decision thatmanagement is considering.
Advantages of absorption (total) costing
• Fixed costs are incurred as a natural part of production. Asabsorption costing includes all relevant production costs in valuingclosing stock a more realistic profit figure can be calculated.
• In marginal costing losses can occur in periods when sales are lowand total fixed costs are written off. If the goods are sold in a laterperiod then a distortion in the profit figures may arise.
ABSORPTION AND MARGINAL COSTING
ABSORPTION AND MARGINAL COSTING (H) 3
• Absorption costing gives better information for pricing products as itincludes both variable and fixed costs.
• Marginal costing may lead to lower prices being offered if the firm isoperating below capacity. Customers may still expect these lowerprices as demand/capacity increases.
Which method should be used?
As both methods have advantages and disadvantages, the precisemethod to use will depend on specific circumstances and the nature ofthe product/business. Where the viability of a product is desired,marginal costing would be used. However, a firm with a long-maturingproduct, such as whisky, may decide absorption costing is the moreappropriate 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 ofover and under-absorption of overheads has been avoided by assumingthat the actual and normal or planned output are the same. This is anunrealistic assumption. Consider the following example.
Normal/planned production level 8,000 unitsNormal/planned fixed overheads £40,000Actual 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 chargedto the finished products, thus this under-absorbed overhead must bededucted from the profit calculated.
