Will vs Going to: Talking About the Future
Will or going to? Learn the difference for decisions, plans, and predictions — with clear examples, the mistakes learners make, and a quick exercise.
English has more than one future, and will and going to are the two you'll reach for every day. They often overlap, but a useful starting point is this: will often appears with decisions made at the moment of speaking, offers, promises, and opinion-based predictions. Going to often appears with plans already decided and predictions based on evidence you can see now.
The core idea
For plans and decisions, ask: was the decision made before now, or right now? For predictions, ask: is it just your opinion, or is there evidence you can see now?
The form
Will is followed by the base verb. Going to uses be + going to + base verb, so be changes with the subject.
When to use will
Instant decisions — you decide as you speak.
Offers, promises, and requests.
Predictions based on opinion — what you think or believe, often with I think, probably, I'm sure.
When to use going to
Plans and intentions — decided before now.
Predictions based on evidence — you can see it coming now.
A note on the present continuous
For fixed arrangements with a time and place — especially with other people — English often prefers the present continuous. It's close to going to, just more definite.
Common mistakes
Using will when you want to emphasize an existing plan.
✓I'm going to travel to Spain next month.
✓I'm traveling to Spain next month. (already arranged)
Will is possible in some contexts, but for an existing plan, going to is usually more natural. For a fixed arrangement with tickets, dates, or other people involved, the present continuous is often the most natural.
Using going to when the decision is made right now.
✓I'll get it.
For a sudden decision, will is the natural default.
Putting will in the if-part of a normal real future condition.
✓If it rains, we'll stay home. (see the conditionals guide)
Use the present tense in the if-part when you mean a future condition: If it rains, we'll stay home. Will can appear in an if-clause only in special meanings, such as willingness: If you'll wait here, I'll call him.
Quick exercise
Choose will ('ll) or going to.
- "I'm cold." — "I ___ close the window."
- We've decided: we ___ move to a bigger apartment.
- Look out — that glass ___ fall!
- I think our team ___ win on Saturday.
- A: Did you call Tom? — B: Oh, I forgot. I ___ do it now.
Answer key
- 'll close (instant decision, reacting now)
- 're going to move (a plan already decided)
- 's going to fall (prediction from evidence you can see)
- 'll win (prediction based on opinion — "I think")
- 'll do (instant decision, decided as you speak)
