- 1以舊換新（折抵的舊品）；折抵價
The used thing you hand over to a seller as part of the payment for the new thing you are buying from them. You buy a new car for 800,000, you give them your old car, they say the old car is worth 200,000, and you pay 600,000 — the old car is the trade-in, and the 200,000 is the trade-in value or trade-in price.

It is used as an adjective too, in front of another noun: trade-in value, trade-in offer, trade-in allowance. The tone is ordinary commercial English, neither formal nor slang, and it is the standard word in a .
trade-in 指買新東西時，交給賣家抵付部分價錢的舊東西，最常見於汽車，手機和相機也是同樣的做法。以汽車為例，新車八十萬，舊車折抵二十萬，舊車是 trade-in，那二十萬就是 trade-in value。有連字號的 trade-in 是名詞，也可以放在名詞前當形容詞，像「trade-in value」；分開寫的 trade in 是動詞，例如「I traded in my old phone」。語氣很平常，是商業場合的標準說法。
