Which statement best describes the 80/20 Rule in a business context?

• A. 80 percent of sales come from 20 percent of customers
• B. 80 percent of customers generate 20 percent of revenue
• C. 20 percent of products account for 80 percent of sales
• D. 50 percent of customers generate all profits

Answer: (A)

The Pareto principle in business shows that a small set of inputs can drive a large share of results. In sales, a common pattern is that a relatively small group of customers accounts for most of the revenue. So the statement that 80 percent of sales come from 20 percent of customers best fits that idea. It highlights where to focus efforts—nurturing and servicing the high-value customers can yield outsized returns and make resource allocation more efficient. Real-world numbers vary, but the key takeaway is the imbalance: a minority of customers often generate the majority of sales. The other options flip the relationship or apply the idea to the wrong element (products rather than customers) or misstate profits, which is why they don’t fit as well.
