Manufacturing Account (Cambridge International IGCSE Accounting)

Manufacturing accounts

What is the total cost of production?

• The total cost of production is the total of the direct costs and the indirect costs

• This is adjusted due to the work in progress not being finished

  • Add the value of the work in progress from the beginning of the year

  • Subtract the value of the work in progress from the end of the year

    • This is similar to dealing with inventory when calculating the net purchases for a trading business

• Cost of production

  • = Direct materials
  • • Direct labour
  • • Direct expenses
  • • Factory overheads
  • • Opening work in progress
  • • Closing work in progress

Exam Hint A business might use a factory and an office. Only the factory expenses are included in the cost of production.

How do I complete a manufacturing account?

• STEP 1 Calculate the cost of materials consumed

  • Start with the opening inventory of raw material

  • Add the purchases of raw materials

    • Subtract purchases returns

  • Add carriage inwards

  • Subtract the closing inventory of raw materials

• STEP 2 Calculate the prime cost

  • Start with the cost of materials consumed
  • Add direct labour
  • Add direct expenses

• STEP 3 Calculate the cost of factory overheads

  • Add together any costs linked to the factory but not the production

    • The production costs should be included in the prime cost

• STEP 4 Add the prime cost and the factory overhead

• STEP 5 Adjust for the work in progress to calculate the cost of production

  • Add the opening balance for the work in progress to the current total cost
  • Subtract the closing balance for the work in progress
  • This final value is the cost of production
