Imagine you need to transport a single kilogram of sugar from Kampala to Jinja, which is about eighty kilometers away, using a truck. Naturally, you’d have to hire the truck, fuel it, and pay the driver. The cost of delivering just one kilogram of sugar this way would be quite high. However, if you fill the truck to its full capacity of 2,000 kilograms of sugar, the total delivery cost stays the same, but the cost per kilogram drops significantly because the expenses are now spread over many more units.
This phenomenon, where the average cost per unit decreases as the volume increases, is known as economies of scale. Economies of scale are incredibly advantageous for businesses, especially in industries where customers are very price-sensitive. They are particularly effective for commodity goods like foodstuffs, salt, and fuel—basic necessities that people buy regularly.
When businesses achieve significant economies of scale, they often end up dominating the market. This dominance can lead to monopoly status, where one company controls a large share of the market. With fewer competitors, this firm can raise prices and enjoy higher profits. Smaller competitors struggle to keep up and may eventually be pushed out of the market.
For any business to survive, it must reach a certain minimum volume of sales. For instance, a school needs a certain number of students to stay open, and a restaurant needs a steady flow of customers. This minimum level of sales is known as the break-even point. At the break-even point, a business covers all its fixed and variable costs, and neither makes a profit nor incurs a loss.
Beyond this, there’s the idea of a profit-even point, where a business not only covers its costs but also makes enough profit to pay shareholders a reasonable dividend and reinvest in growth. Achieving this level of profitability often requires additional investment to scale up the business. Without reaching the necessary scale, it’s challenging to thrive in a competitive market where customers are sensitive to prices.
However, too much scale can lead to diseconomies of scale, where the increased complexity of the operation leads to bureaucracy and increasing costs. The idea is to find a sweet spot where you achieve the lowest unit cost and thereby maximize your profits.
An alternative to achieving scale is to create highly differentiated products and services that are hard to compare directly with others. Think of personalized services provided by artists, singers, and highly specialized professionals. These individuals can charge premium prices because their offerings are unique—there’s only one Taylor Swift or Cristiano Ronaldo, and their exclusivity allows them to command higher fees.
In summary, economies of scale can significantly reduce costs and boost competitiveness in price-sensitive markets. However, businesses can also find success by differentiating their products and services to stand out and avoid direct price comparisons. Whether through scaling up or standing out, the goal is to achieve a sustainable and profitable business model.
