Which job would be more profitable, Interior Designer or Animator?

Erm, I would look at your question in a different light. Which would offer better prospects. I know some interior designers get paid quite a lot of money. Thats ok if you already have loads of money and contacts. same with most jobs i guess. But your unlikely to get a job as an interior Designer, you would have to create your own job. Your more likely to get a job as an animator. and they can be well paid. their are lots of opportunities for animators in bothe film and games indistries. you definately need to get a linked-in account and get your CV up there. I do know someone who has managed to get 2 jobs as an animator this way.

I agree with Col, the important difference between these two is that an animator doesn't need a commission, or access to a property, to demonstrate their talent and do speculative work. i.e. it is easier to be a self-starter as an animator. This matters a huge amount in my experience as an architecture graduate!
