Future Forms: Will, Going To, and Present Continuous
For plans, predictions, and arrangements at B1 and B2, English chooses among three forms: will plus a base verb, be going to plus a base verb, and the present continuous. Will covers on-the-spot decisions, offers, promises, and many predictions. Be going to covers intentions already made and predictions with present evidence. The present continuous covers arrangements that have a time and, usually, another person or a booking.
I'll text you the berth number; we're going to convert the loft in March, and I'm collecting the cello on Thursday.
will for a decision now, going to for a prior intention, present continuous for a fixed arrangement
What it is
English does not mark the future on the main verb the way it marks the past. For the decisions you make every day (Shall I reply now, have I already decided, is it in the diary), three forms do almost all the work. Will is the form of the moment: you decide, offer, promise, or guess as you speak. Be going to reports a decision that already existed, or a future you can see coming from present signs. The present continuous reports an arrangement: a time has been fixed with someone else, or a ticket has been bought. The future perfect and future continuous are a later lesson; this page stays with the three-way choice.
The kettle's boiled. I'll make tea. (decided now) I'm going to make tea after this call. (already intended) I'm making tea for the trustees at four. (arranged)
How to spot it
Ask what the speaker knew before the sentence began. Nothing: will. An intention or a visible sign: going to. A diary slot: present continuous. A public timetable: present simple, treated briefly at the end.
- I'll hold the lamp while you cut the wire. (will: an offer decided as you speak)
- We're going to retile the porch this summer. (going to: an intention already in place)
- I'm meeting the joiner at half past seven. (present continuous: a fixed appointment)
- Look at those clouds: it's going to soak the terrace. (going to: present evidence of a coming event)
Will and going to overlap on many predictions. Going to insists that something in the present already points forward. Will is happier after I think, I expect, and probably.
Future Forms Quick Reference
Which future form for which job
| Job | Form | Example |
|---|---|---|
| Decision, offer, or promise made now | will + base verb | I'll send the berth number in a minute. |
| Intention already made | be going to + base verb | She's going to apply for the loft grant. |
| Prediction from evidence you can see or hear | be going to | That crate is going to slip off the trolley. |
| Prediction from opinion | will | I expect they'll cancel the last crossing. |
| Arrangement with a time and usually a person | present continuous | We're seeing the surveyor on Tuesday. |
| Public timetable or programme | present simple | The last ferry leaves at 21.40. |
| Refusal or willingness | won't / will | The hatch won't shut. I'll try the other bolt. |
Common Future Forms Examples in English
The three-way choice, grouped by what the speaker is doing rather than by form:
Deciding and Reacting
- The queue is tiny. I'll grab the tickets now.
- a decision that did not exist a second ago
- Don't lift that end: I'll take the heavier crate.
- an offer made on the spot
- I won't mention the cracked glaze if they don't.
- a promise, or a refusal to tell
- Shall I leave the lamp on the steps?
- shall with I: an offer shaped as a question
Be going to in these slots would claim a prior plan: I'm going to grab the tickets now sounds as if you had already decided before you saw the queue.
Intentions and Evidence
- They're going to move the archive into the loft in April.
- a plan already agreed
- I'm not going to argue about the invoice again.
- a prior decision, negative
- Careful: that stack is going to topple.
- evidence in front of you
- The tide is going to cut the causeway in twenty minutes.
- a prediction from a present fact, the tide tables
Going to is the honest form when the decision is already made and when the future is readable from now. It is not more 'informal' than will; it is a different meaning.
Arrangements in the Diary
- I'm collecting the cello from the workshop on Thursday.
- a booked pickup, present continuous
- We're having the trustees in the small hall at six.
- an arrangement with other people
- Is she seeing the joiner this week or next?
- asking about someone else's diary
- They aren't coming to the preview; they booked the later train.
- a negative arrangement, already settled
If no time is given and no one else is involved, going to often fits better: I'm going to sort the loft at some point. I'm sorting the loft on Saturday names the slot.
Predictions
- I think the crossing will be rough after midnight.
- will after think: an opinion
- They probably won't mind if we stack the chairs.
- will with probably: a guess
- It's going to be packed: the choir has sold every seat.
- going to: present evidence, the sold-out sign
- You'll like the small hall; the sound is kinder there.
- will: a confident personal prediction
Both forms predict. If you can point at evidence, going to is sharper. If you are offering an opinion, will is the default.
How the Three Forms Are Built and Chosen
The grammar is light. The work is matching the form to the speaker's stance.
Will Plus a Base Verb, Same for Every Subject
Will does not change: I will, she will, they will. The negative is will not (won't). The question moves will in front of the subject. There is no to and no -s on the main verb. In speech will contracts to 'll after pronouns and some nouns: I'll, she'll, the ferry'll be late.
I'll send the berth number. Won't they mind? Will she wait?
affirmative contraction, negative, question
Will + base. Won't. Will she...?
Be Going To Agrees With the Subject
Be changes: am going to, is going to, are going to. The negative goes on be (isn't going to, aren't going to). The question moves be (Are you going to apply?). Going stays in that -ing shape; the main verb after to is bare: going to retile, not going to retiling.
She's going to apply. We aren't going to argue. Are you going to wait?
be agrees; going to plus a base verb
Be agrees; then going to + base.
Present Continuous for a Future Slot in the Diary
The form is the ordinary present continuous (am/is/are + -ing) plus a future time or a clear diary context. Without that future frame, listeners hear a current activity: I'm collecting the cello describes right now. I'm collecting the cello on Thursday describes an arrangement.
I'm collecting the cello on Thursday. What are you doing after the preview?
future time word, or a question about a future slot
Continuous + future time = arrangement.
Choose by What Existed Before You Spoke
If the decision is born in the sentence, will. If the intention or the evidence was already there, going to. If a time has been fixed with the world (a person, a booking, a ticket), present continuous. When two forms are both possible, the difference is attitude, not truth: I'll retile the porch (deciding), I'm going to retile the porch (already decided), I'm retiling the porch on the 12th (in the diary).
I'll retile it. I'm going to retile it. I'm retiling it on the 12th.
now, prior intention, booked slot
Now / already / in the diary.
Common Mistakes with Future Forms
Incorrect: I'm going to grab the tickets now that I see the queue is tiny, I think in this moment.
Correct: The queue is tiny. I'll grab the tickets now.
A decision born from what you have just noticed wants will. Going to would claim the intention was already there before you saw the queue.
Incorrect: I will meeting the joiner at half past seven.
Correct: I'm meeting the joiner at half past seven.
A diary arrangement takes the present continuous, not will plus -ing. Will meeting is not a form. Will meet would sound like a promise rather than a booking.
Incorrect: I'll send the berth number as soon as it will appear.
Correct: I'll send the berth number as soon as it appears.
After as soon as, when, until, and before, English uses a present form even though the meaning is future. Will belongs in the main clause, not in the time clause.
Incorrect: The last ferry will leave at 21.40 every night, according to the board.
Correct: The last ferry leaves at 21.40.
A published timetable takes the present simple. Will leave is a prediction about one occasion, not the schedule itself.
Will and Be Going To: Forms
Full forms first. In speech, will becomes 'll and will not becomes won't; be going to keeps the ordinary contractions of be: I'm, she's, they aren't.
Will plus wait
The same will for every subject, plus the base verb.
| Pronoun | Affirmative | Negative | Question |
|---|---|---|---|
| I | will wait | will not wait | Will I wait? |
| you | will wait | will not wait | Will you wait? |
| he / she / it | will wait | will not wait | Will she wait? |
| we | will wait | will not wait | Will we wait? |
| they | will wait | will not wait | Will they wait? |
Contractions: I'll wait, she won't wait. Shall I wait? is an offer; Will I wait? is a rare, often rhetorical question.
Be going to plus wait
Be agrees with the subject; going to wait does not change.
| Pronoun | Affirmative | Negative | Question |
|---|---|---|---|
| I | am going to wait | am not going to wait | Am I going to wait? |
| you | are going to wait | are not going to wait | Are you going to wait? |
| he / she / it | is going to wait | is not going to wait | Is she going to wait? |
| we | are going to wait | are not going to wait | Are we going to wait? |
| they | are going to wait | are not going to wait | Are they going to wait? |
Contractions: I'm going to wait, she isn't going to wait, they aren't going to wait. Gonna is a speech spelling, not a form to write.
Timetables and Time Clauses
Two extra habits sit beside the three-way choice and catch learners out.
Present simple for schedules
Public timetables and programmes take the present simple, even though the time is future: the ferry, the film, the term, the high tide.
- The last ferry leaves at 21.40.
- a published schedule
- Term starts on the 14th.
- an official calendar
- High tide is at 03.10.
- a tide table, still present simple
I'm leaving at 21.40 is an arrangement about you. The last ferry leaves at 21.40 is the timetable talking. Both can be true in the same hour.
Present forms after when, as soon as, until, before
In a time clause that points forward, English uses a present form, not will: when she arrives, as soon as I hear, until the joiner comes.
- I'll send the berth number as soon as it appears.
- will in the main clause; present in the time clause
- We're going to stack the chairs when the preview ends.
- going to in the main clause; present after when
- Wait here until the joiner calls.
- present after until, future meaning
Will she arrives and as soon as I will hear are the errors this rule blocks. The future marking stays in the main clause.

Future Forms FAQs
- What is the difference between will and be going to?
- Will is for decisions, offers, promises, and guesses that are born as you speak: I'll grab the tickets. Be going to is for intentions that already existed and for predictions with present evidence: We're going to retile the porch. That stack is going to topple. For many opinions about the future, either form is possible; going to is sharper when you can point at a sign.
- When do I use the present continuous for the future?
- When the future is an arrangement: a time is fixed, and usually another person or a booking is involved. I'm collecting the cello on Thursday. We're seeing the surveyor on Tuesday. Without a future time word, the same form means right now, so add on Thursday, at six, this week, or a clear diary context.
- Can I use will for a plan I have already made?
- You can, and people do, but going to (or the present continuous if it is in the diary) is the more precise form. I'll apply for the loft grant sounds like you are deciding now. I'm going to apply reports a standing intention. I'm applying on the 3rd reports a scheduled act.
- Why do we say The last ferry leaves at 21.40 if it is future?
- Because the present simple is the form for official schedules and programmes: ferries, films, terms, tides. The timetable is treated as a present fact. I'm leaving at 21.40 is your arrangement; The last ferry leaves at 21.40 is the board's statement.
- Do I put will after when or as soon as?
- Not in the time clause. I'll send the number as soon as it appears. We're going to stack the chairs when the preview ends. Will stays in the main clause. As soon as it will appear is the error to unlearn.
