The Rule
| Form | Use | Example |
|---|---|---|
| will | Spontaneous decision, prediction, promise, offer | I'll send it to you right now. |
| going to | Intention/plan already decided; evidence-based prediction | We're going to launch in Q3. / Look at those clouds — it's going to rain. |
| Present Continuous | Fixed arrangement with another person | I'm meeting the client at 3pm tomorrow. |
| Present Simple | Timetable / scheduled event | The conference starts at 9am on Tuesday. |
| Future Perfect | Completed before a point in the future | By Friday, we will have submitted the proposal. |
| Future Continuous | In progress at a point in the future | This time next week I'll be presenting in Berlin. |
Will vs Going to — the key distinction:
Spontaneous/unplanned → will: "The printer is broken." "I'll fix it."
Already decided/planned → going to: "I'm going to restructure the team next month."
Future Perfect: will + have + past participle
By the end of Q4, we will have exceeded all targets.
