Why Do We Say “a Grand” for $1,000? As billionaires overtake millionaires, $1,000 may not be the biggest amount of money one can imagine, but it nevertheless has an imposing nickname. Here’s why we refer to this specific amount of cash as “a grand.”

 

In English, the concept of money has plenty of nicknames: “cash,” “moolah,” “bucks,” “dough,” “bread,” “scratch,” etc. But only a few specific amounts of money have sobriquets of their own. For example, $1,000 is commonly called “a grand,”  a term that was coined in the early 20th century.

One of the earliest known uses of “grand” as slang for a thousand dollars dates back to a 1915 edition of The Boston Daily Globe. At the time, a thousand bucks was considered a “grand sum” of cash, hence the nickname we still use. And while it might not be quite as life-changing in the context of today, when you take inflation into account, $1,000 in 1915 is roughly equivalent to $32,000 in 2025, which is an impressive sum of money — one might even say it’s grand.

Of course, slang evolves as language does, and we now have a colloquialism for “grand” (which is itself a colloquialism). People sometimes shorten “grand” to “Gs,” so if someone says “five Gs,” they mean $5,000. While we’re on the topic of single letters, a thousand is also sometimes represented by the letter “K.” This has to do with the prefix “kilo-,” a term derived from the ancient Greek khilioi, meaning “thousand.” In other words, $5,000 in cash can be represented by either “five Gs” or “five K.”
