Have you ever looked at the price of something and thought, “There’s no way I’m paying that much”? Maybe it was a dream vacation, a new phone, a car, or even a simple meal at an expensive restaurant. When something costs far more than you expected, you might hear someone say, “That’ll cost an arm and a leg.”
At first, the phrase sounds pretty dramatic. Thankfully, nobody is actually asking you to trade an arm and a leg for a purchase! It’s a colorful English idiom used to describe something that is extremely expensive.
But where did this strange expression come from? What exactly does it mean, and how can you use it naturally in conversation? Let’s break down the meaning of “cost an arm and a leg,” explore its possible origins, and look at plenty of real-life examples.
What Does “Cost an Arm and a Leg” Mean?
The phrase “cost an arm and a leg” means that something is very expensive or costs a huge amount of money.
For example:
“That new car looks amazing, but it costs an arm and a leg.”
The person isn’t saying that the car literally costs body parts. They simply mean that the car is so expensive that buying it would require spending a large amount of money.
You can use the phrase when talking about almost anything expensive:
- A house
- A car
- A vacation
- College tuition
- Designer clothes
- Electronics
- Concert tickets
- Medical treatment
- Luxury restaurants
It is usually used in a casual or conversational way.
Simple Meaning
Cost an arm and a leg = Be extremely expensive.
Example:
“I’d love to stay at that hotel, but it costs an arm and a leg.”
In other words:
“That hotel is ridiculously expensive.”
The expression often adds a little humor or exaggeration to a conversation. Instead of simply saying something is expensive, you make the statement more colorful.
Where Did “Cost an Arm and a Leg” Come From?
The exact origin of “cost an arm and a leg” is uncertain, which makes the history of the phrase especially interesting.
The expression became widely known in American English during the 20th century, particularly after World War II. Several theories have been suggested about where it came from, but there isn’t solid historical evidence proving one single origin.
One popular theory connects the phrase to the high human cost of war. Losing an arm or a leg would represent an enormous personal sacrifice, so saying something “cost an arm and a leg” became a powerful way of describing an unusually high price.
Another theory suggests that the expression may have developed from earlier phrases involving paying a very high personal price or making a serious sacrifice.
There are also stories claiming that newspaper or portrait photographers once charged different amounts depending on how much of a person was shown in a photograph. However, this explanation is generally treated as an unproven story rather than an established origin.
So, while the exact origin remains unclear, the meaning is very clear: something costs an unusually large amount.
Why Do People Say “Cost an Arm and a Leg”?
English is full of idioms that aren’t meant to be taken literally.
For example:
- “Break a leg” doesn’t literally mean breaking your leg.
- “Hit the books” doesn’t mean punching books.
- “Spill the beans” doesn’t involve actual beans.
- “Cost an arm and a leg” doesn’t involve losing body parts.
The phrase works because an arm and a leg represent something extremely valuable and personal. Saying that you would have to give up both emphasizes just how expensive something feels.
It is essentially a humorous exaggeration.

1. When Your Crush Says It
Your crush might say:
“That restaurant costs an arm and a leg.”
A playful response could be:
Best reply: “Then maybe we should find somewhere that only costs a finger or two. 😂”
It keeps the conversation light without taking the complaint too seriously.
2. When a Friend Jokes About an Expensive Purchase
Your friend might say:
“This gaming PC costs an arm and a leg.”
You could respond:
Best reply: “At that price, it better make my coffee too.”
This works especially well when you’re already joking around.
3. When Someone Says It Too Early in a Conversation
If someone suddenly complains about the price of something, you don’t need to make the conversation complicated.
Best reply: “Seriously? What makes it so expensive?”
This naturally keeps the conversation going.
4. When You’re Not Interested in Buying It
If someone recommends something expensive, you can be honest without being rude.
Best reply: “It looks great, but it’s outside my budget right now.”
That’s clear, mature, and respectful.
5. When You Actually Think It’s Worth the Money
Sometimes expensive things really are worth buying.
Best reply: “It’s expensive, but considering how often I’d use it, I think it could be worth it.”
This shows that you’re thinking about value rather than simply reacting to the price.
Common Mistakes to Avoid
1. Taking the Phrase Literally
Someone saying something “costs an arm and a leg” isn’t talking about actual body parts.
It’s simply an exaggerated way of saying “very expensive.”
2. Using It in Extremely Formal Writing
The expression is casual and conversational. It can work in informal articles, stories, messages, and everyday speech, but a formal financial report might call for more precise language.
Instead of:
“The project costs an arm and a leg.”
A formal report might say:
“The project requires a substantial financial investment.”
3. Using It for Something Only Slightly Expensive
If a coffee costs a little more than usual, saying it “cost an arm and a leg” may sound overly dramatic.
The phrase works best when the price is genuinely high or you’re intentionally exaggerating for humor.
4. Repeating the Idiom Too Often
Using the same expression repeatedly can make your writing sound unnatural.
Mix it with alternatives such as:
- Very expensive
- Cost a fortune
- Pricey
- Overpriced
- Cost a small fortune
- Break the bank
5. Forgetting the Tone
“Cost an arm and a leg” often has a humorous or dramatic tone. Think about the situation before using it.
Pro Tips for Using “Cost an Arm and a Leg”
1. Use It Naturally
Don’t force the idiom into every conversation about money. It sounds best when you’re genuinely surprised by a high price.
2. Match the Situation
With friends, you can make it funny:
“That car costs an arm and a leg!”
In a professional setting, something like “That’s quite expensive” may be more appropriate.
3. Use It for Emphasis
The phrase is especially effective when you want to show that something is far more expensive than expected.
For example:
“The hotel looked affordable online, but parking alone costs an arm and a leg!”
That gives the sentence more personality.
