3.3 – Costs and Revenues
Understanding costs and revenues is essential for every business. Costs are the expenses incurred to produce goods or services. Revenues are the total money received from sales and other business activities. Managing these helps maximize profit and achieve business objectives.
Types of Costs
- Fixed Costs: Do not change as output changes (e.g., rent, salaries, insurance).
- Variable Costs: Change with the level of output (e.g., raw materials, direct labor, packaging).
- Semi-variable Costs: Have both fixed and variable elements (e.g., telephone bills, overtime pay).
- Direct Costs: Directly related to production (e.g., raw materials, wages of production workers).
- Indirect Costs (Overheads): Not directly linked to specific products, but needed for the business (e.g., administration, marketing, utilities).
- Opportunity Cost: The value of the next best alternative foregone when a decision is made.
Cost Formulas
\[ \text{Total Cost (TC)} = \text{Fixed Cost (FC)} + \text{Variable Cost (VC)} \]
\[ \text{Average Cost (AC)} = \frac{\text{Total Cost (TC)}}{\text{Output (Q)}} \]
\[ \text{Opportunity Cost} = \text{Value of Next Best Alternative} \]
\[ \text{Total Cost (TC)} = \text{Fixed Cost (FC)} + \text{Variable Cost (VC)} \]
\[ \text{Average Cost (AC)} = \frac{\text{Total Cost (TC)}}{\text{Output (Q)}} \]
\[ \text{Opportunity Cost} = \text{Value of Next Best Alternative} \]
Total Revenue & Revenue Streams
- Total Revenue (TR): The total income from selling all goods and services.
Formula: \[ \text{Total Revenue (TR)} = \text{Price (P)} \times \text{Quantity Sold (Q)} \] - Revenue Streams: Sources of business income, including:
- Sales of goods/services – Primary stream for most firms
- Interest income – Earnings from financial assets and investments
- Dividends – Shares of profit from investments in other companies
- Rent income – Earnings from letting property or assets
- Royalties – Income from licensing intellectual property, patents, or copyright
- Subscriptions – Membership or recurring payments
- Commission – Fees for brokering sales or business deals
- Advertising revenue – Sale of promotional opportunities on platforms
