Sales Forecasting (Edexcel A Level Business)

Revision Note

The Purpose of Sales Forecasts

  • Sales forecasts predict future revenues based on past sales figures

  • Sales forecasts commonly focus on what will happen in the future to:
    • The volume and value of sales
    • The size of the market
    • Sales as a result of promotional activity
    • Sales as a result of cyclical factors

  • Sales forecasts are an important tool to support planning and can improve the validity of cash flow forecasts

  • Businesses use sales forecasts to determine resource requirements in a variety of ways, including:
    • How many staff will be needed?
    • How much stock will be required?
    • Does capacity need to be expanded (or reduced)?
    • Does the equipment need to be upgraded, replaced or increased (or reduced)?
    • How much and which type of finance will be required?
    • Is promotional activity (e.g. advertising) required - and when?

Factors Affecting Sales Forecasts

  • Developing accurate sales forecasts is a skill and requires an understanding of several factors which can influence the reliability of the forecast
     

The Factors that can Cause Sales Forecasts to be Adjusted Upwards or Downwards


Factor


Explanation

Consumer Trends

Seasonal variations

  • Demand for certain goods is seasonal

  • Events such as major religious festivals, holiday periods and annual events impact demand for a wide range of products
    • For E.g. sales of basic homewares increase when students start university each September

Fashion

  • Fashion is often led by celebrities and their influence can have a relatively short-term impact on sales
    • E.g. When Hollywood legend Megan Fox appeared in September 2021 at a star-studded event in a Boohoo dress the company’s sales unexpectedly soared by over 400% during that month

Long term trends

  • Consumer behaviour, attitudes and spending habits change over time
    • In recent years environmentally-conscious consumers have led to many businesses amending sales forecasts to reflect increased demand for green products
      • E.g. In late 2022 vehicle manufacturer Ford increased its sales forecasts for electric vehicles by almost 70% 

Economic Variables

Economic Growth

  • During periods of economic growth, increased consumer incomes will lead to higher than forecast sales
  • The opposite will occur during periods of economic slowdown and sales may be less than forecast

Inflation

  • The general increase in prices over time reduces consumers’ spending power
    • Firms may revise their sales forecasts downwards during periods of rising inflation
    • Firms may revise their sales forecasts upwards during periods of falling inflation

Unemployment

  • Increased levels of unemployment are often experienced during periods of recession and tend to be a key cause of reduced spending in the economy
    • Sales forecasts for lifestyle and luxury goods may reduce as consumers focus their spending on essentials

Interest Rates

  • When interest rates rise borrowing becomes more expensive for consumers
  • Businesses that sell products that consumers frequently buy on credit may therefore adjust their sales forecasts downwards
    • E.g. Property sales are set to drop to 1.01billion in 2023 from 1.27b in 2022 causing many estate agencies to adjust their sales forecasts downwards

Exchange Rates

  • Where the value of UK sterling falls against other global currencies, overseas consumers will find British exports become relatively cheaper

  • Businesses that sell products overseas or that cater for tourists visiting the UK may adjust their sales forecasts upwards to reflect the expected increase in demand from a cheaper £
    • E.g. Visit Britain expects the number of tourists entering Britain in 2023 will be 14% higher than in 2022

Actions of Competitors

 

  • Sales forecasts should consider short-term actions of competitors such as sales promotions as well as longer-term strategies such as changes to product ranges and expansion plans

  • Competitor actions are difficult to predict so the use of past data to predict future sales may be limited as a result
    • E.g. Marks and Spencer announced plans to open twenty new high street stores in 2023, partly in response to the closure of several key competitors including Debenhams

Difficulties of Sales Forecasting

  • Sales forecasting usually involves the use of past data to predict the future
  • In the short-term, sales forecasts are likely to reflect the recent past
  • Longer-term sales forecasting is often more problematic as several factors affect its reliability

The Difficulties of Sales Forecasting

 

  • Effective sales forecasting requires skill, time and the accurate use of timely data
    • Smaller businesses in particular may lack the experience or specialised personnel to construct, analyse and interpret sales forecasts
      • It is difficult to avoid experience bias (e.g. opinions of the future based on experiences in the past) 
      • Businesses may face problems in constructing sales forecasts that ignore the priorities of key stakeholders

  • The future seldom repeats the occurrences of the past
    • Sales forecasts will rarely reflect the full range of external influences that can affect future inflows such as fashions, trends, the actions of competitors 

  • There is a significant amount of data available for businesses to consider when constructing sales forecasts
    • Internal data such as previous sales figures will be a key source of information when constructing forecasts
    • Selecting the most appropriate external data to support sales forecasts is extremely challenging and will require careful evaluation

Exam Tip

Whilst sales forecasting as a planning tool has several potential uses for a business, you should carefully consider how a sales forecast is constructed when evaluating its usefulness. 

Who is responsible for the sales forecast? 

Which data is used in its construction? 

How reliable or accurate are the data sources underpinning the forecast? 

You may even conclude that no sales forecasting is better than a poorly-constructed, biased attempt!
