What is revenue?
Total income a business earns from selling goods or services.
This section covers fundamental concepts of business finance, focusing on revenue generation, cost structures, and break-even analysis—essential tools for profitability and strategic planning.
Revenue is the total income a business earns from selling goods or services. It is sometimes called “sales turnover.” Increasing revenue is often a key objective.
Calculated by multiplying the number of units sold by the selling price per unit. Example: 1,000 units at £10 each.
Costs are expenses a business incurs to operate. They are divided into two main categories.
Total costs are the sum of fixed costs and variable costs at a particular level of output.
Profit signals financial success. If costs are greater than revenue, the business incurs a loss.
Interest Impact: Interest is the cost of borrowing money or the income earned on savings. Interest paid on loans is an additional expense included in total costs; interest received contributes to profit.
Break-even is the point where total revenue exactly equals total costs (zero profit and zero loss). It is critical for planning.
A break-even chart visually represents costs, revenue, and output on a graph.
What is revenue?
Total income a business earns from selling goods or services.
How is revenue calculated?
Revenue = Number of units sold × Selling price per unit.
What are fixed costs?
Costs that do not change with output level, e.g., rent, salaries.
What are variable costs?
Costs that vary directly with output, e.g., raw materials.
How do you calculate total costs?
Total costs = Fixed costs + Variable costs.
What formula calculates profit?
Profit = Revenue - Total costs.
What happens if total costs exceed revenue?
The business incurs a loss.
What is interest in a business context?
Cost of borrowing money or income earned from savings/investments.
Define break-even output.
The number of units sold where total revenue equals total costs.
What is the margin of safety?
Difference between actual output and break-even output.
What shifts the break-even point upward?
Increase in fixed costs or variable costs.
What effect does increasing selling price have?
Raises revenue line, lowers break-even output, and increases profit potential.
