Understanding Types of Costs in Business
- To run a bakery, you’ve rented a cozy space, hired staff, and stocked up on ingredients.
- Some expenses, like rent, stay the same no matter how many croissants you sell, while others, like ingredients, increase with production.
- Understanding the different types of costs: fixed, variable, direct, and indirect is essential for managing your finances and making informed decisions.
Costs
A cost refers to the expenditure a business incurs while producing goods or services. Typical costs include payments for raw materials, wages, rent, and fuel.
Set-up Costs vs. Running Costs
Set Up Costs
The initial expenses incurred when starting a business, such as purchasing equipment, legal fees, and branding costs.
Examples of Set-up Costs
- Purchasing equipment and machinery
- Software setup and IT infrastructure
- Legal fees (e.g., business registration, permits)
- Employee training for new processes
Running Costs
The ongoing expenses required to operate a business, including salaries, rent, utilities, and maintenance.
- Running costs, also known as operating costs, are the ongoing expenses required to maintain day-to-day business operations.
Examples of Running Costs
- Salaries and wages for employees
- Rent and utilities (electricity, water, internet)
- Raw materials and supplies
- Maintenance and repair expenses
"Costs" refer to expenses incurred to produce goods or services, while "price" is the selling price that includes profit.
- Avoid circular definitions.
- For instance, don’t write, “Set-up costs are costs for setting up a business.” Clearly define terms with examples to gain marks.
Fixed Costs: Expenses That Don’t Change with Output
Fixed costs
Fixed costs remain constant, regardless of production levels.
- They do not vary but become more efficient when spread over higher production volumes.
- This is called economies of scale.
Examples of Fixed Costs
- Rent: Lease payments for premises stay constant, no matter how much you produce.
- Salaries: Managers earning a fixed monthly wage.
- Insurance: Property or liability insurance premiums.
- Loan Repayments: Monthly interest payments on loans.
A drone manufacturer incurs €5 million in fixed costs annually, whether it produces 10,000 or 70,000 drones.
- For cost calculations, mention that fixed costs do not change with output.
- This distinguishes them from variable costs.
Variable Costs: Expenses That Fluctuate with Production
Variable costs
Variable costs change in proportion to the level of output.
- Following the idea of economies of scale, this also applies to purchasing economies of scale, where as output grows, businesses can negotiate better deals on materials.
Examples of Variable Costs
- Raw Materials: Ingredients like flour and sugar for a bakery.
- Packaging: Boxes and bags for baked goods.
- Utilities: Electricity for running ovens or refrigeration.
Total Costs
- Adding both fixed costs and variable costs will give the value of total costs.
- Thus: $$\text{Total fixed cost + Total Variable cost = Total Cost}$$
Total Costs
The sum of all expenses incurred in producing a good or service.
Direct Costs: Product-Specific Expenses
Direct Costs
Expenses that can be directly linked to the production of a specific product or service, such as raw materials and labour costs.
- In your bakery, these would include costs like the ingredients used to bake a cake or the wages paid to bakers who work exclusively on producing pastries.
Characteristics of Direct Costs
- Product-specific: These costs are incurred for a particular product or service.
- Easily traceable: Direct costs can be assigned to a specific cost object (e.g., a product, project, or department).
- Always trace direct costs to a particular product.
- For example, packaging is a direct cost if it’s used solely for one product.
Indirect Costs: General Operational Expenses
Indirect Costs
Expenses that are not directly tied to the production of a specific product but are necessary for the overall operation, such as utilities, office supplies, and administrative expenses.
- Also known as overheads, these are expenses that cannot be easily traced to a specific product or service.
- These costs support the overall operation of your business but are not directly tied to production.
Characteristics of Indirect Costs
- Not product-specific: These costs support the business as a whole.
- Harder to allocate: Indirect costs are usually spread across multiple products or services.
Costs Formulae
Key: $\mathrm{Q}$ = Quantity (or level of output)
| Total Cost ($\mathrm{TC}$) | $\mathrm{TC=TFC + TVC}$ |
|---|---|
| Total Variable Costs ($\mathrm{TVC}$) | $\mathrm{TVC= AVC \times Q}$ |
| Total Fixed Costs ($\mathrm{TFC}$) | $\mathrm{TC= AFC \times Q}$ |
| Average Fixed Cost ($\mathrm{AFC}$) | $\mathrm{AFC =\frac{TFC}{Q}}$ |
| Average Variable Cost ($\mathrm{AVC}$) | $\mathrm{AVC=\frac{TVC}{Q}}$ |
| Average Cost ($\mathrm{AC}$) | $\mathrm{AC=\frac{TC}{Q}} \text{ or } \mathrm{AC= AFC + AVC}$ |
Why Understanding Costs Matters
- Distinguishing between these types of costs is more than just an academic exercise, it’s a practical tool for running a successful business:
- Pricing Decisions: Knowing your fixed, variable, direct, and indirect costs helps you set prices that cover expenses and generate a profit.
- Profitability Analysis: By understanding direct and indirect costs, you can determine which products are most profitable.
- Cost Control: Identifying high fixed or indirect costs allows you to find ways to reduce them and improve efficiency.
- Break-even Analysis: Fixed and variable costs are key components in calculating the break-even point, the level of sales needed to cover all expenses.
- Can you identify whether the following are fixed, variable, direct, or indirect costs?
- Monthly rent for a factory.
- Wages paid to assembly line workers.
- Electricity used to power the entire factory.
- Raw materials for manufacturing a product.
