What this dot point is asking
AQA wants you to explain why businesses exist, what adding value means (and how to calculate it), the difference between needs and wants, and how businesses combine inputs to produce goods and services. This is the foundation of the whole course, so the definitions must be precise.
Why businesses exist
Businesses exist to satisfy customers' needs and wants by producing goods and services, and in doing so to generate a return for their owners (profit) or, for social enterprises and the public sector, to deliver a social benefit. They transform inputs into outputs that people value enough to pay for, which is how they survive and grow. Without meeting a real customer need or want, a business has no market and cannot last.
Needs and wants
The distinction matters for marketing and resilience: businesses meeting needs (basic food, utilities) tend to have steadier demand through a downturn, while those meeting wants (luxuries, discretionary goods) see demand fall sharply when incomes tighten.
Combining inputs to produce output
Adding value
Why adding value matters
Adding value is central because it underpins the margin a business earns and its ability to charge a price above input costs. Firms add value through branding, design, quality, service, convenience and unique features. The more value a customer perceives, the higher the price they will accept, and the more competitive and profitable the business can be. It links directly to differentiation and pricing later in the course.
Exam-style practice questions
Practice questions written in the style of AQA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
AQA 20194 marksA furniture maker buys of materials per table and sells each finished table for . Calculate the value added per table and explain what it represents. (4 marks)Show worked answer →
Show the calculation.
Value added selling price cost of bought-in materials per table.
Explanation: the is the value the business has added to the raw materials through its work (design, craftsmanship, finishing, branding). It is not all profit, because the firm must still cover its other costs such as labour and overheads out of it, but it shows how much extra value the production process creates over the bought-in inputs. Markers reward the correct calculation (price minus input cost) and an explanation that value added is the extra value created, not the same as profit.
AQA 20186 marksExplain how a business could add value to its product to justify a higher price. (6 marks)Show worked answer →
Adding value means increasing the difference between the cost of inputs and the price customers will pay.
A business could add value through branding (a trusted name customers will pay more for), superior design or quality, excellent customer service, convenience, or unique features. For example, turning basic coffee beans into a branded, well-presented cafe experience lets the firm charge far more than the bean cost. The greater the perceived value to the customer, the higher the price they accept, widening the margin. Markers reward identifying valid methods of adding value and explaining the link from added value to a higher price customers will pay, ideally in context.
