A useful tidbit I noted in Korean Grammar in Use: Intermediate regarding expressing the degree of certainty of future plans:
- V+(으)ㄹ 거예요: When referring to a virtually definite plan, ‘going to’
- V+(으)려고 하다: When referring to a likely plan, ‘planning to’
- V+(으)ㄹ까 하다: When referring to a vague intention, ‘thinking about doing’
