There Ain’t No Such Thing As A Free Lunch – TANSTAAFL

… a core term used in Economic Analysis and Atlas102


Investopedia (reference below) defines There Ain’t No Such Thing As A Free Lunch (TANSTAAFL) as an acronym that attempts to describe the cost of decision making and consumption.

Investopedia goes on to say:

“There ain’t no such thing as a free lunch” (TANSTAAFL) expresses the idea that even if something seems like it is free, there is always a cost, no matter how indirect or hidden.”

“… A free lunch is a situation in which a good or service is received at no cost, with the true cost of the good or service ultimately borne by some party, which may even include the recipient. A “free lunch” was often offered during the 1800s to bar patrons who ordered drinks as a way of bringing in more business, though in modern times the term is used to describe anything purportedly received for free. From this, “free lunch” became an investment slang term referring to unlimited riskless profits.”
