Both phrases mean that something doesn't matter very much to you, or that something isn't important, or doesn't worry you very much. There is a difference, however. 'I don't mind' is a fairly polite response, suggesting 'That's fine/ There's no problem/ I'm ok with that 'I don't care' can be seen as quite a rude response, suggesting that you are really not interested in something. So, here's a question for you: If you are at someone's house, and they offer you a choice of apple juice or orange juice, which response would you give?

Many of my students have asked me to explain the difference between "I don't mind" and " I don't care" so I will do that today. "Don't care" means you don't care about what happens. It won't change your views at all. "Don't mind" means you are allowing it to happen. For example: Tom: Would you please lend me $1.000? Martha: No Tom: Then I won't talk to you ever again. Martha: I don't care./I couldn't care less/Big deal *** Mr. Smith: I'll be in the hospital for a week. Mrs. Jones (a neighbor): Is there anything I can do to help? Mr. Smith: Well, since you mentioned it. Is there any chance you could collect my mail every day? I hate to bother you. Mrs. Jones: I don't mind. It's my pleasure/ I don't mind. I have nothing else to do anyway except to watch TV.

I think ''I don't mind'' means something like '' it doesn't bother me. I give you permission'' . Meanwhile, ''I don't care'' is similar to ''I'm not concerned about it'' But actually, they are the same in some situations :D

I don't mind -->It's OK,it won't be any trouble for me(polite) I don't care-->do whatever you like and it will be no difference to me,(provoke)

It's good question I want to know answer also
