Future Forms: Will, Going To, and the Future Perfect

English has no single future tense. Will, be going to, the present continuous, the present simple, and the continuous and perfect forms of will each say something different about a future event: when it was decided, whether it is arranged or scheduled, and whether it will be in progress or finished at a given moment.

Choosing a form will, be going to, or a present formFuture aspect in progress, finished, or how longForm and timing time clauses

One future, several forms

Choose the form by what you want to say about the event, not by how far away it is.

What you want to say Form Example
A decision made right now, an offer, a promise will It’s dark in here. I’ll turn on the light.
A plan decided before now be going to I’m going to repaint my bedroom this summer.
A prediction from present evidence be going to The battery is at 2 percent. My phone is going to die.
A prediction from opinion will I think the price of coffee will go up.
A personal arrangement present continuous We’re having a video call with the client at ten.
A timetable or official schedule present simple The exam starts at 9:30 on Tuesday.
Something within moments be about to Quiet, please. The speech is about to begin.
In progress at a future moment will be + -ing At noon tomorrow, I’ll be sitting in a job interview.
Finished before a future moment will have + past participle By Monday, the office will have moved to the new building.
How long, up to a future moment will have been + -ing By August, he’ll have been training for a year.

A common shortcut says will is for facts and be going to is for plans. It is a simplification: both forms can predict, and both can describe intentions. The more reliable question is whether the decision or the evidence already exists at the moment of speaking.

Continuous, perfect, and perfect continuous

All three look at the same future moment. The difference is where the action sits in relation to it.

Future continuous, perfect, and perfect continuous timeline

Unreal futures

For futures that depend on an unlikely or imagined condition (If I won the scholarship, I would study abroad), see the second conditional. Conditionals guide →

Possible futures

For a future that is possible but not certain (It might rain later, She may be late), use a modal verb. Modal verbs guide →

Shall appears mainly in offers and suggestions (Shall I open the window? Shall we start?) and in formal or legal writing. In everyday statements, will is the normal choice.

1

Choosing a form

Will or be going to

Did you decide just now or before? Is the prediction based on evidence or opinion?

The rule: Use will for decisions made while speaking, offers, promises, and predictions based on opinion. Use be going to for plans made earlier and predictions based on present evidence.

When was the decision made?

Clue in the context Form Example
Reacting to something you just heard or saw will A: The bin is full. B: I’ll take it out.
Offering or promising will I’ll send you the notes tonight. I won’t tell anyone.
Already decided, bought, booked, or promised earlier be going to I’ve downloaded the app. I’m going to learn Italian.

What is the prediction based on?

Basis Form Example
Something visible or known now be going to He’s running very fast on ice. He’s going to slip.
Opinion, often with I think, probably, I’m sure, I expect will I expect the meeting will be short.

When both are possible

Many predictions accept either form (It will rain later / It’s going to rain later). The contrast matters most for decisions: a decision made before speaking sounds odd with will, and one made while speaking sounds odd with be going to.

Common errors in this part

  • be going to for a decision made nowA: The printer's jammed. B: I'm going to fix it.✓ A: The printer's jammed. B: I'll fix it.B decides the moment they hear about the problem.
  • will for a plan made earlierI bought a guitar last week because I'll learn to play.✓ I bought a guitar last week because I'm going to learn to play.The intention existed before the guitar was bought.
  • present simple for a plan or predictionLook at him. He falls off that ladder!✓ Look at him. He's going to fall off that ladder!Present evidence predicts the fall; the present simple cannot.
2

Choosing a form

Arrangements, timetables, and be about to

Is it booked, on a timetable, or about to happen? Is the story set in the past?

The rule: Use the present continuous for personal arrangements, the present simple for timetables, be about to for the next few moments, and was going to or was about to in a story about the past.

Meaning Form Example
Personal arrangement (agreed, booked) present continuous I’m having my hair cut on Saturday.
Timetable, program, opening hours present simple The next ferry departs at 4:20.
Within moments be about to Turn off your phone. The plane is about to take off.
A plan seen from the past was / were going to We were going to eat outside, but it rained.
Just before something in the past was / were about to I was about to leave when my boss called.

Present simple for a personal plan

A personal plan in the present simple (I study tonight) sounds like a fixed fact of the world rather than an intention. Use be going to or the present continuous. Some business and travel itineraries do use the present simple (We fly to Osaka on Monday), because they read like a schedule.

How soon is about to?

Be about to normally means seconds or minutes away. In casual speech it can stretch to very soon, but it does not combine with a stated later time such as next month or next year.

Common errors in this part

  • present simple for a plan or predictionI play tennis with Leo tomorrow at six.✓ I'm playing tennis with Leo tomorrow at six.An agreed plan with a set time takes the present continuous.
  • be about to with a later timeMy cousin is about to get married in October.✓ My cousin is getting married in October.October is not within moments.
  • present form in a past storyHe said he is going to call, but he never did.✓ He said he was going to call, but he never did.The plan is seen from a past point.
3

Form and timing

Time clauses

Is the blank after when, until, or as soon as, or in the main clause?

The rule: After when, before, after, until, once, as soon as, and by the time, use a present form (present simple or present perfect) for the future. Put will in the main clause.

Grammar recap

If follows the same pattern: If it rains, we will stay inside (not If it will rain). The first conditional is covered in full, with unless and other connectors, in the Conditionals guide. Conditionals guide →

Time words that take a present form

whenbeforeafteruntilonceas soon asthe momentby the timewhile

Which clause is the blank in?

Time clause Main clause
As soon as the parcel arrives, I‘ll let you know.
Until the bridge reopens, drivers will need a detour.
Once you‘ve paid, you‘ll get a receipt by email.

The time clause can come first or second. The rule depends on which clause the verb is in, not on the order.

Common errors in this part

  • will after when, until, or as soon asWe'll start as soon as everyone will arrive.✓ We'll start as soon as everyone arrives.After as soon as, the verb stays in the present.
  • present form where the future is neededOnce the box office opens, I buy the tickets.✓ Once the box office opens, I'll buy the tickets.The main clause needs will.
  • will after when, until, or as soon asI won't leave until I will have finished.✓ I won't leave until I've finished.No will in the time clause, even in the perfect.
4

Future aspect

In progress or finished?

At that future moment, is the action still happening or already done?

The rule: Will be + -ing shows an action in progress at a future moment. Will have + past participle shows it finished before then. Stative verbs keep the simple form.

Question Form Example
Still happening at that moment? will be + -ing When the guests arrive, we’ll still be cooking.
Already done by that moment? will have + past participle When the guests arrive, we’ll have finished cooking.
A stative verb (know, be, own, need)? will + base form By tonight, we’ll know the answer.

Clues

In progress: this time tomorrow, at that moment, when you arrive, all afternoon. Finished: by, by the time, already, before.

Polite questions

Will you be using the car tonight? asks about someone’s plans without sounding like a request. Will you use the car? can sound like asking them to do it.

Common errors in this part

  • plain will where aspect is neededAt 3 a.m., most of the city will sleep.✓ At 3 a.m., most of the city will be sleeping.Sleeping is in progress at that moment.
  • in progress and finished mixed upBy the time we get there, the show will be starting already.✓ By the time we get there, the show will have started already.By the time and already point to completion.
  • stative verb in the continuousTomorrow you will be understanding the plan better.✓ Tomorrow you will understand the plan better.Understand is a stative verb.
5

Future aspect

Duration up to a future point

Are you measuring how long, or counting how many?

The rule: Will have been + -ing measures how long up to a future point. Use will have + past participle for how many, for stative verbs, and in the passive.

Question Form Example
How long, up to that point? will have been + -ing By June, I’ll have been teaching for twenty years.
How many, by that point? will have + past participle By June, I’ll have taught over 3,000 classes.
Stative verb will have + past participle By June, I’ll have had this job for twenty years.
Passive will have been + past participle By June, the old school will have been demolished.

Three parts

The future perfect continuous has three helpers before the -ing form: will + have + been. Leaving out been (will have working) is a common slip.

Negatives and questions are possible (How long will you have been living here?), but the form is most common in statements.

Common errors in this part

  • will have + -ing without beenIn May, we will have dating for two years.✓ In May, we will have been dating for two years.Duration needs will have been + -ing.
  • continuous with a number of finished thingsBy noon, I will have been answering 50 emails.✓ By noon, I will have answered 50 emails.Fifty emails is a count of finished things.
  • present perfect for a future pointNext year, he has worked here for a decade.✓ Next year, he will have worked here for a decade.Next year is a future point, so will is needed.

Self-check

Is each sentence correct? Tap to see the answer. The part label tells you where to look if you were not sure.

Part 1Oh no, I've spilled my coffee! Don't worry, I'll get a cloth.

Correct. A decision made at the moment of speaking takes will.

Part 1I've decided. I'm going to take the job in Chicago.

Correct. The decision came before speaking, so be going to fits.

Part 2The festival opens on Friday at noon.

Correct. An official program takes the present simple.

Part 2I'm about to move to a new city next spring.

Incorrect. About to means within moments. Use: I’m going to move (or I’m moving) to a new city next spring.

Part 4By the end of the week, the painters will be finishing the whole house.
