5.5 Manufacturing Accounts


2026 Syllabus Objectives

By the end of this topic, you should be able to:

  1. Distinguish between direct and indirect costs
  2. Understand direct material, direct labour, prime cost, and factory overheads
  3. Understand and make adjustments for work in progress
  4. Calculate the factory cost of production
  5. Prepare manufacturing accounts, income statements, and statements of financial position
  6. Make adjustments to financial statements (as covered in topic 5.1 for sole traders)

1. What Is a Manufacturing Business?

A manufacturing business is one that makes the goods it sells. Instead of buying finished products and reselling them, it buys raw materials (the basic inputs needed to make something) and converts those materials into finished products inside a factory.

For example, a furniture company might buy wood, nails, and varnish, then use factory workers and machinery to turn those materials into chairs and tables.

Because of this production process, manufacturing businesses need to prepare an extra financial statement called a manufacturing account, in addition to the usual income statement and statement of financial position.

The Three Financial Statements for a Manufacturing Business

StatementPurpose
Manufacturing AccountCalculates the total cost of making the goods (the "cost of production")
Income StatementCalculates the gross profit and net profit from selling those goods
Statement of Financial PositionShows what the business owns and owes at a specific date

2. Direct Costs vs Indirect Costs

All costs in a manufacturing business fall into one of two categories.

Direct Costs (also called Variable Costs)

Direct costs are costs that are directly linked to making the product. If the business makes more products, direct costs go up. If it makes fewer products, direct costs go down. In other words, they change with the level of output.

Think of it this way: if you are making wooden chairs, the wood itself is a direct cost — more chairs means more wood needed.

Indirect Costs (also called Fixed Costs or Factory Overheads)

Indirect costs are costs that are not directly linked to making each individual product. They stay roughly the same regardless of how many items are produced. These are the costs of keeping the factory running — the "background" expenses.

For example, the rent for the factory building stays the same whether the business makes 100 chairs or 1,000 chairs.
