Following are main Contract Expenses and Costs which shows in Contract Account under Contract Costing :- • 1. Material Cost Material or raw material which is used for construction is the main expense or contract cost and it will be debited in contract account. It is supplied from store or purchased from market directly. If material is transferred from any other contract, then its cost will be adjusted on the basis of material transfer note. • 2. Labor Cost On the basis of wages analysis sheet, labor cost is calculated for a specific contract order. If same labourer is used more than one contract, then time devoted to each contract is calculated and on this basis, labor cost is allocated. • 3. Direct Expenses We also add direct expenses, if any. • 4. Overheads Overheads can be allocated on the basis of some % on cost of material, wages or prime cost or MHR or LHR. By:Shiba Prasad Dahal
5. Sub- Contract Cost • It will also include in contract cost, if to complete sub-construction for main construction. • 6. Cost of Extra Work. • Importance of Contract Costing • Contract costing is important because with this method, we can calculate cost of big jobs.

So, it is better for us to learn all things which is in contract costing. By:Shiba Prasad Dahal
