Revenue, Costs and Profit
Calculating and interpreting revenue, fixed and variable costs, total cost, profit and loss in context.
How to study for GCSE Business
Learn each concept as a cause-and-effect chain, practise calculations with units, apply evidence from the case and justify decisions against the business's objectives.
Core concepts
Concept 1
Sales revenue equals selling price multiplied by quantity sold; a rise in either factor does not guarantee profit if costs also change.
Exam cue: Write the formula, substitute units carefully and show the business meaning of the result.
Concept 2
Fixed costs do not vary directly with output in the relevant period, while total variable cost changes as output changes.
Exam cue: Classify the cost by how it behaves as output changes in the stated period.
Concept 3
Profit equals revenue minus total costs and must be interpreted alongside objectives, investment, time period and cash position.
Exam cue: Trace a price, volume or cost decision through both revenue and total cost before judging profit.
Risk pitfalls and guardrails
Using units produced when the revenue formula requires units sold.
Guardrail: Do not stop at a generic advantage or disadvantage: use the case, check the calculation and keep board-specific paper claims separate from the common core.
Calling every recurring cost variable.
Guardrail: Do not stop at a generic advantage or disadvantage: use the case, check the calculation and keep board-specific paper claims separate from the common core.
Assuming higher revenue necessarily means higher profit.
Guardrail: Do not stop at a generic advantage or disadvantage: use the case, check the calculation and keep board-specific paper claims separate from the common core.
Memory anchors
Sales revenue
Selling price × quantity sold.
Fixed cost
A cost that does not vary directly with output in the relevant period.
Variable cost
A cost that changes with the level of output.
Total cost
Fixed costs + total variable costs.
Profit
Sales revenue − total costs; a negative result is a loss.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
