Economies of Scale

What Are Economies of Scale?

Economies of scale occur when companies reduce costs per unit as they produce more.

👆 By the way, an interesting fact: Henry Ford revolutionized economies of scale in 1913 with the assembly line, reducing the time to build a car from 12 hours to 2.5 hours.
