Profit
Profit is the amount by which revenue exceeds the costs of producing and providing goods or services.
A business earns revenue when people pay for the goods or services it provides. The business also bears costs: labor, materials, rent, equipment, transportation, insurance, technology, marketing, and countless other expenses.
When revenue exceeds those costs, the difference is profit. When costs exceed revenue, the difference is loss.
This simple calculation plays an enormously important role in economic life because profit and loss provide information and incentives about how resources are being used.
Profit and Voluntary Exchange
In ordinary voluntary exchange, a customer buys something because he values what he receives more than the money he gives up.
Suppose a restaurant offers a meal for $25. Nobody is required to buy it. A customer who voluntarily pays $25 demonstrates through his choice that, at that moment, he prefers the meal to the $25 in his wallet.
The restaurant takes the opposite side of the exchange. It prefers receiving the $25 to keeping the food, labor, table space, and other resources required to provide the meal.
Both parties agree to the exchange because each expects to be better off afterward. This is why voluntary exchange is not necessarily a zero-sum contest in which one person’s gain must equal another person’s loss.
Profit and Value
Profit does not arise merely because a business wants money. A business must ordinarily persuade customers to part voluntarily with their money. That requires offering something customers value enough to purchase.
A carpenter might build a table. A physician might provide medical care. A mechanic might repair an automobile. A software company might create a useful program. A farmer might produce food.
In each case, customers decide whether the product or service is worth the price.
This connects profit directly to the Key Idea Wealth and Money. To create wealth for yourself, create value for others.
Profit provides a powerful incentive for businesses to discover what other people need, want, or value—and then find efficient ways to provide it.
Specialization Makes Profit Possible
As discussed under the Key Idea Business , businesses organize specialized labor, knowledge, capital, skills, and technology. This specialization allows businesses to produce many things more efficiently than customers could produce them individually.
Imagine manufacturing your own smartphone truly and entirely from scratch. You would need to acquire raw materials from around the world, develop or acquire the tools and machinery required to extract and process them, design sophisticated electronics, write software, manufacture components, assemble them, and make the finished device work reliably.
Attempting to reproduce that entire productive process yourself would be prohibitively expensive and, for any ordinary individual, effectively impossible. Buying a smartphone from a specialized business, however, is vastly easier and less expensive.
The business can charge more for the phone than it costs to produce and distribute it while still offering the customer something he values more highly than the price he pays. Specialization can therefore benefit both producer and customer.
Customer Value Is Not the Same as Profit
The value a customer receives from a purchase should not be confused with the profit earned by the business.
Suppose you would willingly pay as much as $1,000 for a particular product but can purchase it for $700. You receive something you value more highly than the money you surrender.
The business, meanwhile, might spend $650 producing, marketing, and delivering that product. Its profit would be $50—not the full $700 purchase price. Customers and producers can therefore both gain from the same exchange.
Economists sometimes describe the difference between what a customer would have been willing to pay and what he actually pays as consumer surplus. The broader lesson is simple: business profit and customer benefit are different things, and both can exist simultaneously. It is win-win.
Profit and Loss
Profit is only half of the market signal. Loss matters too.
A business earns profit when revenues exceed costs. Persistent losses indicate that customers do not value the business’s output enough to cover the costs of producing it. Suppose a company spends $1 million producing something customers are willing to buy for only $600,000. The loss signals that the resources being used are not generating enough customer value to cover their cost.
Those resources may be capable of producing greater value elsewhere. The owners must improve the product, reduce costs, find different customers, change the business—or eventually stop using resources in that particular way.
Profit and loss therefore create powerful incentives for businesses to pay attention to customers and use scarce resources efficiently. This connects directly to the Key Idea Incentives Matter.
Profit Is Not Proof of Virtue
Profit itself is not necessarily morally good. A person can become richer through theft, fraud, coercion, political favoritism, or deception. Someone might also profit by selling something harmful to willing customers.
Profit therefore does not prove that a person or business is virtuous or that every profitable transaction is just. The moral character of profit depends partly upon how it is earned.
The case for profit-seeking as socially beneficial is strongest where property rights are protected, fraud and coercion are prohibited, competition exists, and exchanges are voluntary. Under those conditions, businesses seeking profit generally have strong incentives to serve other people because customers remain free to say no and take their money elsewhere.
Why Profit Matters
Profit allows successful businesses to survive, invest, expand, develop new products, hire workers, accumulate capital, and continue serving customers. Loss disciplines businesses that consume more resources than customers are willing to support.
Profit therefore performs both an informational and an incentive function. It rewards businesses that discover valued uses for scarce resources and gives entrepreneurs reasons to search continually for better ways to serve others.
Profit is not proof of virtue. But under conditions of honest and voluntary exchange, profit is evidence that a business has created something customers value more than the resources required to provide it.
