The term “Free Lunch” is often used to denote something that appears to be available at no cost. However, the more commonly recognized full expression, “there’s no such thing as a free lunch” (TANSTAAFL), implies that everything has a cost, whether visible or hidden.
Origin and Historical Context
Early Usage
The phrase originates from the practice in the 19th-century American saloons where patrons were offered free meals, albeit with the expectation that they would purchase drinks. This practice illustrated the broader economic principle that even so-called free offerings have underlying costs for the provider.
Popularization
The expression gained further popularity in the mid-20th century, partly due to its frequent use by economist Milton Friedman and its inclusion in Robert Heinlein’s science-fiction work, “The Moon is a Harsh Mistress.”
Economic Implications
The Principle of TANSTAAFL
The principle suggests that in economics, one cannot get something for nothing. Resources are finite, and allocating them to one purpose involves opportunity costs—the foregone benefits of the next best alternative use of those resources.
Opportunity Cost
Economists emphasize the concept of opportunity cost when explaining why there is no free lunch. Even if a good or service is free to the consumer, it incurs a cost somewhere in the supply chain.
Subsidies and Hidden Costs
Sometimes governments or organizations may subsidize free goods or services. These subsidies are typically funded by taxes or reallocations of resources, illustrating that the costs are merely transferred rather than eliminated.
Applicability and Examples
Real-World Examples
- Promotional Offers: Businesses often give away products or services for free to attract customers. For example, a free trial of a streaming service is designed to convert users into paying subscribers.
- Public Services: Although public services like healthcare or education may be free at the point of use, they are funded through taxation.
- Enviromental Impact: “Free” plastic bags or complimentary bottled water often come at an environmental cost, reflecting the broader societal impact.
Comparisons
Free Market vs. Subsidized Economy
- Free Market: In a free market, prices reflect the intersection of supply and demand, ensuring that the cost of resources is transparent.
- Subsidized Economy: In a subsidized economy, the government intervenes to provide goods and services at lower rates or for free, often redistributing the costs through taxation or public debt.

Summary
The expression “Free Lunch” often misleadingly suggests that something valuable can be obtained without cost. However, the fuller adage, “there’s no such thing as a free lunch”, underscores the economic reality that costs are always borne somewhere in the system, whether by individuals, businesses, or society at large. This principle highlights fundamental economic concepts such as opportunity costs and resource allocation, reiterating that every benefit has a corresponding cost.
