Which concept describes the cost difference between acquiring new customers and retaining existing ones?

• A. Kotler's Idea
• B. Pareto Principle
• C. Moore's Law
• D. Murphy's Law

Answer: (A)

The main idea here is that it generally costs more to acquire a new customer than to retain an existing one. This concept, often attributed to Kotler, emphasizes that attracting newcomers requires substantial upfront marketing, promotions, and outreach, while existing customers already know your brand and are more likely to buy again with less persuasion. In addition, loyal customers can increase their lifetime value through repeat purchases, upselling, and referrals, all of which tend to cost less per sale than winning a new customer. The other terms cited don’t describe this cost dynamic: the Pareto Principle is about the 80/20 distribution, Moore’s Law about technology growth, and Murphy’s Law about things that can go wrong.
