(e) The advantages of standard costing. Any four of the following:


• The preparation of budgets is made easier if they are based on standard costs, and the budgets are likely to
be more realistic.
• Differences between actual and budgeted results (variances) are easier to identify if standard costs are
used.
• The activities that are responsible for variances are highlighted.
• Standard costing is an essential part of responsibility accounting because it highlights activities that give
rise to variances (See §34.2.).
• Estimated costs of new products and quotations for orders may be prepared more efficiently when
standard costs for materials and operations have been calculated.
• Although standard costing is usually associated in people’s minds with manufacturing industries, it is
equally useful in all kinds of businesses, including service industries such as hotels and hospitals.
• Valuation of stock at standard cost is acceptable for the purposes of the Companies Act 1985 and the
accounting standards, if the standards approximate to actual cost and are reviewed regularly.
