Will vs. Going To
Both “will” and “be going to” can refer to the future, but the choice often reflects meaning and viewpoint. “Going to” commonly marks prior plans or predictions based on present evidence; “will” commonly covers predictions, immediate decisions, offers, promises, and other modal uses.
Use “going to” especially for prior plans and evidence-based predictions; use “will” for many predictions, immediate decisions, offers, and promises. They overlap, so context controls the choice.

Further guidance
Overlap Boundary
The forms overlap in future reference; do not reduce the distinction to a single mechanical tense rule.
Planning Boundary
For a decision already made before speaking, “be going to” is often the more natural choice.
