35. 35. Cost Estimation•It is the process of determining in advance the costof a product, job, order or service.• In cost estimation, an allowance is made for anticipated fluctuations in the prices of elements of cost i.e. materials, labour and overheads.

Opening Materials Inventory 70,000 Closing Materials Inventory 9,800 Purchase of Materials 1,05,000 Factory Wages 1,90,000 Factory expenses 35,000 Establishment Expenses 20,000 Opening finished stock Nil Closing finished stock 70,000 Sales 3,78,000
