Revision is a collection of short, clear explanations covering the core areas of business studies, including finance, marketing, operations, people, globalisation, and strategy. Each note breaks down key ideas and decision-making tools into simple, exam-friendly summaries. The aim is to make complex topics easier to understand, revise, and apply. It’s a quick-reference space for building strong business knowledge step by step.
Net Present Value (NPV) is a financial method used to assess whether an investment is worthwhile by calculating the total value of future cash flows in today’s money, minus the initial cost. A positive NPV means the project is expected to generate profit beyond the required rate of return, while a negative NPV suggests the investment should be rejected. It is one of the most reliable investment appraisal techniques studied at GCSE and A-Level Business.
The Average Rate of Return (ARR) measures the annual percentage profit a business expects to earn on an investment, relative to the initial cost. It helps businesses compare projects and decide where to allocate funds. ARR is popular because it is simple to calculate and easy to understand, but it ignores the timing of cash flows and can oversimplify complex investment decisions.
The payback period measures how long it takes for an investment to repay its initial cost from the cash inflows it generates. It is one of the simplest methods of investment appraisal, favoured by businesses for its ease of calculation and clear focus on liquidity. The main advantages include simplicity and quick risk assessment, while key disadvantages are that it ignores profitability after the payback point and the time value of money.
Decision trees are visual diagrams used by businesses to map out choices, possible outcomes, and their financial consequences. They help managers compare options by calculating expected monetary values, reducing the risk of costly mistakes. This guide covers the definition, features, advantages, disadvantages, calculation steps, and evaluation of decision trees for GCSE and A-Level Business Studies students.
Absenteeism is the habitual or frequent absence of employees from work without valid reason. It is measured as a percentage using a simple formula, and high rates signal problems with motivation, management, or working conditions. Businesses track absenteeism to identify workforce issues, reduce costs, and improve productivity. Understanding this metric is essential for GCSE and A-Level Business Studies students.
Labour turnover measures the percentage of employees leaving a business over a set period. It is calculated by dividing the number of staff who leave by the average number of employees, then multiplying by 100. A high rate signals potential problems with pay, management, or working conditions, while a low rate suggests strong staff retention and satisfaction.
Labour productivity measures the output produced per worker over a given period. It is calculated by dividing total output by the number of employees. A rise in productivity per worker means a business is getting more from its workforce, which can lower unit costs and boost profitability. Understanding this metric is essential for GCSE and A-Level Business Studies students, as it connects to efficiency, competitiveness, and human resource management.
YED measures how demand changes as income changes, guiding pricing and product decisions. It can help businesses predict demand for luxury and inferior goods during economic change.
Labour retention measures how well a business keeps its employees over a set period. A high retention rate suggests strong job satisfaction, effective management, and competitive pay, while a low rate signals problems that could increase costs and reduce productivity. This metric is essential for GCSE and A-Level Business Studies students to understand, calculate, and evaluate.
A community interest company (CIC) is a special type of limited company designed to use its profits and assets for the benefit of a community rather than private shareholders. CICs must pass a “community interest test” and are regulated by the CIC Regulator. They can trade, earn profits, and pay staff, but face restrictions on profit distribution.
