'Economies of scale' sounds complicated but it simply means: as a company produces more, the cost per unit tends to fall. Here is the clean explanation, with examples and the limits to watch.
What Are Economies of Scale?
When output rises, fixed costs (factory, software, marketing) spread across more units, reducing the average cost of each. That is how big firms underprice small ones.
Why It Happens
- Buying power: bulk purchasing lowers input prices.
- Fixed-cost spreading: same factory, more products.
- Specialisation: bigger teams divide work more efficiently.
- Access to cheaper capital: larger firms borrow at better rates.
Example: A Bakery
One oven serves 100 loaves at ₦400 per loaf. Doubling sales nearly halves the fixed cost per loaf, letting the bakery lower prices and still profit — a classic economy of scale.
When It Stops Helping (Diseconomies)
Past a certain size, coordination, bureaucracy and complexity can raise costs again — the 'diseconomy of scale' that many large companies hit.
FAQ
Are economies of scale available to small businesses?
Yes, through group buying, outsourcing, tech tools and partnerships.
Why do airlines use scale economies?
More passengers per flight and more flights per hub cut the cost of every seat, letting airlines price aggressively.
