Importance (Advantages) and Limitations of Management Accounting

Management accounting has become an indispensable tool of modern management, but like every tool it has limits, and a balanced view recognises both.

Importance / advantages of management accounting

• Better planning and forecasting. It supplies the data and the techniques (budgets, forecasts) that make planning realistic and target-setting possible.
• Improved decision-making. By placing analysed, relevant information before management, it leads to sounder decisions on pricing, product mix, make-or-buy and similar matters.
• Effective control. Through budgetary control and standard costing it enables management to control costs and performance and to correct deviations promptly.
• Increased efficiency and profitability. By highlighting waste, idle capacity and unprofitable activities, it helps raise the overall efficiency and profit of the business.
• Better coordination. Its budgets and reports help the various departments work together towards common goals.
• Useful interpretation of accounts. It converts complex accounting figures into a form that ordinary managers can understand and act upon.
• Helps in performance appraisal and motivation. By measuring actual against targeted performance, it helps evaluate managers and motivate staff.
• Service to management at every level. It provides the right information to the right level of management at the right time.

Limitations of management accounting

• It is only as good as the data it uses. Management accounting draws on financial and cost accounting; if those records are inaccurate or incomplete, its conclusions will be wrong too.
• It does not replace management or its judgement. It only supplies information; the decision, and the responsibility for it, remain with management, and its usefulness depends on how well managers use it.
• It deals largely with estimates. Because it is concerned with the future, it relies on forecasts and estimates, which may not come true, so its results are not certain.
• It is a wide, evolving field without settled principles. Being a blend of many disciplines and still developing, it has no rigid, universally agreed rules, so its application depends heavily on the skill of the person using it.
• It is expensive. Installing and running a full management accounting system needs trained staff and elaborate records, which a small business may not be able to afford.
• There can be resistance to change. Introducing the system may be resisted by staff who dislike the extra work and the closer scrutiny it brings. …
