COST ACCOUNTING
UNIT – I B.COM 5th Semester (SW)
EVOLUTION OF COST ACCOUNTING
The widespread interest in the subject of cost accounting could be said to have developed with
Industrial Revolution which started in 1760. As mechanization, simplification, standardisation and mass
production followed in the wake of factory system, costing had to keep pace with these developments.
Until the 18th century, cost accounting was in the domain of the engineer. Its integration with financial
accounting began when accountants started to audit the cost records. Under the influence of financial
accountant, cost accounting came to be viewed almost exclusively as a means of inventory valuation
and profit measurement. It has grown only in the 20th century as an independent discipline. Cost
accounting has found to be of assistance to management, in compiling and providing requisite statistical
data. It has developed rapidly and assisted management in providing valuable information to take
appropriate decision in time. Cost Accounting throws light on the excessive waste of materials,
inefficient labour operations, idle machinery and many other similar factors, which are responsible for
reduction in the profit of the business activities. Managements found that cost accounting could render
valuable assistance in planning, controlling and coordinating the activities.
