1: Introduction to management accounting and costing ⏐ Part A Cost determination and behaviour
1 What is cost accounting?
Cost accounting is a management information system which analyses past, present and future data to provide the basis
for managerial action.
1.1 The cost accountant
Who can provide the answers to the following questions?
• What was the cost of goods produced or services provided last period?
• What was the cost of operating a department last month?
• What revenues were earned last week?
Yes, you've guessed it, the cost accountant.
Knowing about costs incurred or revenues earned enables management to do the following.
(a) Assess the profitability of a product, a service, a department, or the whole organisation.
(b) Perhaps, set selling prices with some regard for the costs of sale.
(c) Put a value on inventory (raw materials, work in progress, finished goods) that are still held in store at the
end of a period, for preparing a statement of financial position showing of the company's assets and
liabilities.
That was quite easy. But who could answer the following questions?
(a) What are the future costs of goods and services likely to be?
(b) How do actual costs compare with planned costs?
(c) What information does management need in order to make sensible decisions about profits and costs?
Well, you may be surprised, but again it is the cost accountant.
1.2 Cost accounting and management accounting
Management accounting, and nowadays cost accounting, provide management information for planning, control and
decision-making purposes.
Originally cost accounting did deal with ways of accumulating historical costs and of charging these costs to units of
output, or to departments, in order to establish inventory valuations, profits and statement of financial position items. It
has since been extended into planning, control and decision making, so that the cost accountant is now able to answer
the second set of questions. In today's modern industrial environment, the role of cost accounting in the provision of
management information is therefore almost indistinguishable from that of management accounting, which is basically
concerned with the provision of information to assist management with planning, control and decision making.
Cost accounting is the 'gathering of cost information and its attachment to cost objects, the establishment of budgets,
standard costs and actual costs of operations, processes, activities or products; and the analysis of variances,
profitability or the social use of funds'. CIMA Official Terminology
So, as you can see, the cost accountant has his or her hands full! Don't worry about the terms mentioned in CIMA's
definition – all will become clearer as you work through this Study Text.
