Study Notes
Overview
Understanding Revenue, Costs, Profit and Loss is the bedrock of business finance. Every examiner across AQA, Edexcel, and OCR will test these concepts rigorously, often allocating 15-20% of the total marks to financial calculations and their interpretation. You are expected not just to memorise formulas, but to apply them to specific business scenarios, calculate profitability ratios, and make justified recommendations based on financial data. The difference between a Level 2 and Level 3 response often lies in your ability to explain why a change in profit margin matters to the business's future success.
Core Concepts
Revenue
Revenue (or turnover) is the total amount of money brought in by a company's operations, measured over a set period. It is the top line of an income statement.
Formula: Revenue = Price × Quantity Sold
Examiner Tip: Do not confuse revenue with profit. Revenue is money coming in before any costs are deducted. Candidates who use the terms interchangeably lose marks immediately.
Costs
Costs are the expenses a business incurs in producing and selling its goods or services. They are split into two main categories:
Fixed Costs (FC): Costs that do not change with the level of output in the short term.
Examples: Rent, manager salaries, insurance, loan repayments.
Variable Costs (VC): Costs that change directly with the level of output.
Examples: Raw materials, packaging, direct labour (wages paid per unit produced).
Total Costs (TC): The sum of all fixed and variable costs.
Formula: Total Costs = Fixed Costs + Variable Costs
Profit and Loss
Profit is the financial gain when revenue exceeds total costs. Loss occurs when total costs exceed revenue.
Gross Profit: The profit a business makes after subtracting the costs directly associated with making and selling its products.
Formula: Gross Profit = Revenue - Cost of Sales
Net Profit: The actual profit after working expenses (overheads) not included in the calculation of gross profit have been paid.
Formula: Net Profit = Gross Profit - Other Expenses
Profitability Ratios
Profitability ratios measure a company's ability to generate earnings relative to its revenue, operating costs, or investment over time.
Gross Profit Margin (GPM): Shows the percentage of revenue that is kept as gross profit.
Formula: GPM = (Gross Profit ÷ Revenue) × 100
Net Profit Margin (NPM): Shows the percentage of revenue that is kept as net profit after all costs.
Formula: NPM = (Net Profit ÷ Revenue) × 100
Average Rate of Return (ARR): Measures the annual profitability of an investment as a percentage of the initial investment cost.
Formula: ARR = (Average Annual Profit ÷ Cost of Investment) × 100

State the formula for calculating Total Costs. (1 mark)
Hint: Think about the two main types of costs.
A business sells 2,000 units at £15 each. Calculate its revenue. (2 marks)
Hint: Revenue = Price × Quantity
Explain the difference between gross profit and net profit. (2 marks)
Hint: What is deducted to get gross profit vs net profit?
A business has a revenue of £100,000, cost of sales of £40,000, and other expenses of £25,000. Calculate its Net Profit Margin. (4 marks)
Hint: You need to find Gross Profit, then Net Profit, then calculate the margin.
Evaluate whether a business should focus on increasing its gross profit margin or its net profit margin to improve its overall financial health. (9 marks)
Hint: Consider what each margin measures and which gives a truer picture of the business's final financial position.
