(Eco. ), PH. D PG Diploma in PMIR & PG Diploma in Journalism and Mass Communication INTRODUCTION Accounting of Overheads is one of the most important & technical aspect of Cost accounting. From Cost reduction & Cost control point of view, overhead play a great role. So, proper understanding of computation and accounting of overhead is must for Students of commerce. Meaning of OVERHEADS??? Overheads is the aggregate of indirect materials cost, indirect labour cost and indirect expenses which cannot be conveniently identified with and directly allocated to a particular cost centre or cost object.
Example- Indirect Material Cost Indirect Labour Cost Indirect Expenses Distribution Of Overheads Step 1 -> Classification of Overheads Step 2 -> Collection of Overheads Step 3 -> Allocation of Overheads Step 4 -> Apportionment of Overheads Step 5 -> Re-apportionment of service department overheads Step 6 -> Absorption of OverheadsClassification Of Overheads By Function • Production Overheads • Administrative Overheads • Selling Overheads • Distribution Overheads By Behaviour • Fixed Overheads • Variable Overheads By Element • Indirect Materials • Indirect Labour • Indirect Expenses Collection of Overheads ?Collection of overheads means the collection of various items of overheads under suitable account heading and a unique Standing Order Number(S. O. N. ) or Cost Account Number(C. A. N.
