割引 : 할인

[BobaBunny5]

Is it necessary to use -의 before or does it sound find/natural without it?

[TheBrownjay]

"Fifty percent off" should be accepted

[klodak]

Not exactly since 할인 refers to more of a discount that is 50% than saying "50% will be cut off."

You could have a meaning more similar to 50% off if you say 50% 깎다, but usually thats used as a sentence like "50프로 깎았다," (the price was cut 50%) "50프로 깎아줄게" (i'll cut the price 50% for you

Usually in stores you could see signs saying 50% 할인 or even just the word "sale" in big capital letters with the discounted price or the percentage

[n.aandeg]

No, he's right. 'Cutting off' the price is giving a discount, these are literally the same meaning in English.

[Jeong-JinL]

I'm not sure when there would be a difference in meaning between the two. Can someone give an example?
