Costing concepts
1. Direct or raw materials cost
1. The materials that go into the final product.
1. Example: Wood
2. Direct labour cost
2. The labour costs of those workers directly involved in the manufacturing of goods.
2. Example: Workers who cut the wood
3. Prime cost
3. Costs that are directly involved in the production of finished goods.
3. Direct material + Direct labour
4. Indirect material cost
4. The materials that do not form part of the finished product, but are still necessary in the
4. production process.
4. Example: Cleaning materials
5. Indirect labour cost
5. The workers that are not directly involved in the production process
5. Example: Factory manger
6. Factory overheads
6. All costs that are incurred in order to run the factory.
6. Includes indirect materials and indirect labour costs.
6. Example: Electricity, rent, depreciation
7. Fixed costs
7. These costs remain constant within a period of time irrespective of the amount of good
7. produced.
7. Example: Rent
8. Variable costs
8. These costs vary in direct proportion to the amount of goods produced.
8. Example: Direct materials
9. Total cost of production
9. = Raw materials + Direct labour + Factory overheads
10. Unit cost
10. The cost of one item.
𝑇𝑜𝑡𝑎𝑙 𝑐𝑜𝑠𝑡 𝑜𝑓 𝑝𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑜𝑛
10. = 𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑢𝑛𝑖𝑡𝑠 𝑝𝑟𝑜𝑑𝑢𝑐𝑒𝑑
11. Mark up
11. The profit the business adds to the cost.
12. Selling price
12. = Cost price + Mark up
, Breakeven point
The number of items that need to be sold so that neither a profit or loss is achieved
𝑓𝑖𝑥𝑒𝑑 𝑐𝑜𝑠𝑡𝑠
=
𝑆𝑃 𝑝𝑒𝑟 𝑢𝑛𝑖𝑡 − 𝑉𝐶 𝑝𝑒𝑟 𝑢𝑛𝑖𝑡
Contribution per unit
= Selling price per unit – Variable cost per unit
Example:
Selling price Variable cost Contribution Fixed cost Breakeven

Productivity
= The ratio between a certain amount of output and a certain amount of input
Number of products produced : Number of hours worked
The higher the productivity the better.
The workers are therefore producing more with the same input.
Increasing productivity of people, results in higher profits.
