trade in

give an old item as part payment for something new

B2

What does "trade sth in" mean?

To trade in something means to hand over an old item at a shop or dealership, where its value is counted as part of the payment for something new. The key idea is that there is always a financial transaction involved — the retailer gives you a credit or discount in return for your old item, which reduces the cost of your new purchase. This is different from simply selling something or swapping it with a friend, because a business (such as a car dealership or electronics retailer) acts as the middleman. You'll often hear this phrasal verb in consumer contexts: phone upgrades, car purchases, or gaming console deals. The hyphenated noun 'trade-in' is also very common — for example, asking about the 'trade-in value' of your current device before you decide to upgrade.

Examples

How to use it

trade in + object (old item)

The most common pattern — the object is the old item being surrendered to a retailer in exchange for credit toward a new purchase.

She decided to trade in her old laptop before the sale ended.

trade + object + in

When the object is a noun phrase, the verb and particle can separate — this is equally natural and very common.

He traded his old phone in and got £150 off the latest model.

trade + pronoun + in

When the object is a pronoun, separation is obligatory — the pronoun must go between the verb and the particle.

My laptop was almost three years old, so I traded it in last month.

trade in + object + for + new item

Use 'for' to mention what you are buying in exchange — this is the most complete and idiomatic form of the pattern.

They traded in their old car for a more fuel-efficient model.

object + be traded in (passive)

The passive form is natural, especially in retail or commercial contexts when the focus is on what happened to the old item.

Thousands of old smartphones are traded in every week at that chain of stores.

Common Mistakes

Pronoun placement

When the object is a pronoun (it, them, etc.), it must go between 'trade' and 'in'. Placing the pronoun after 'in' is ungrammatical in English.

✗ I decided to trade in it for a newer model.
✓ I decided to trade it in for a newer model.
Confusing 'trade in' with 'trade up'

'Trade up' means to move to something better or more expensive, but it doesn't imply a part-exchange deal with a retailer. 'Trade in' specifically involves handing over an old item to a shop or dealer as part of the payment — the commercial transaction is essential.

✗ I traded up my old phone at the shop and got money off the new one.
✓ I traded in my old phone at the shop and got money off the new one.
Separating with a very long noun phrase

When the object is a long or complex noun phrase, it is more natural to keep 'trade in' together rather than splitting it around the object, to avoid awkwardness.

✗ I traded the phone that I bought two years ago when I first moved abroad in.
✓ I traded in the phone that I bought two years ago when I first moved abroad.

Usage

This phrasal verb is neutral and equally common in both British and American English, especially in advertising and consumer contexts. The noun form 'trade-in' (hyphenated) is also very useful — for example, 'What's the trade-in value of my old phone?'

Frequently Asked Questions

Can 'trade in' be used without mentioning what you are buying in return?

Yes, it's perfectly natural to use 'trade in' without specifying the new item — for example, 'I'm thinking of trading in my car.' The context usually makes it clear that a new purchase is involved. You only need to add 'for + new item' when you want to be more specific.

Does 'trade in' always involve a shop or dealership?

Yes — 'trade in' specifically implies a commercial transaction, where a business gives you credit or a discount in exchange for your old item. If you're swapping something directly with another person and no money or credit is involved, 'trade in' would not be the right choice.

What kinds of items are typically 'traded in'?

The most common objects are consumer goods with a resale value, such as cars, phones, laptops, games consoles, bikes, and watches. These are all things a retailer or dealer can realistically accept and resell. You wouldn't normally use 'trade in' for items like clothing or food.

Is 'trade-in' (with a hyphen) related to 'trade in'?

Yes — 'trade-in' is the noun form of the same expression. It refers either to the old item being exchanged or to the deal itself, for example: 'What's the trade-in value of my phone?' or 'They offered me a great trade-in deal.' It's very common in advertising and retail contexts.

Is 'trade in' used more in British or American English?

It's equally common in both British and American English. You'll hear and read it in advertising, at car dealerships, in electronics stores, and in everyday conversation in both varieties. There's no regional preference to worry about.
