The future is the tense used to predict or express future events.

We use the future simple to express spontaneous decisions, opinions and hopes {see Future Simple, A2 level}.

Be going to is used to express intentions for the future and make previsions based on signs we see at that moment {see Be going to, A1 level}.


Future simple (will) and be going to have different structures for the three forms:

Affirmative forms:

  • Future simple: Subject + will + verb + …
  • Be going to: Subject + to be + going to + verb + …

Negative forms:

  • Future simple: Subject + will + not + verb + …
  • Be going to: Subject + to be + not + going to + verb + …

Interrogative forms:

  • Simple future: Will + subject + verb + …?
  • Be going to: To be + subject + going to + verb + …?


Future simple:

Decision made at the moment of speaking

  • We don’t have any bread for dinner. I will go and buy some from the bakery.


  • Will you come with us to meet the president?

Needs/duties/future events

  • You will have to pay with cash if you buy clothes under 50 euros.


  • will help you to make these photocopies.

Predictions based on opinions

  • He thinks that being retired will be boring.


  • I promise I will never talk to the boss about this! 


  • The telephone is ringing. Will you answer it please?

Sentences containing the adverbs: probably, certainly, perhaps

  • will certainly come to the party.
  • He probably won’t finish writing his CV in time.
  • Perhaps we will need a new printer soon. This one is getting so slow.


  • If you don’t send an email, I will not talk to you again.

Be going to:

Decision before the moment of speaking/planned activity

  • We don’t have paper for the printer. I am going to get some.

Predictions based on evidence about the near future

  • This business isn’t going to fail. It’s a multinational corporation!


We use future simple to express:

  • Decisions made while speaking;
  • Invitations;
  • Needs/duties/future events;
  • Offers;
  • Predictions based on opinions;
  • Promises;
  • Requests;
  • Sentences containing the adverbs: probably, certainly, perhaps;
  • Threats.

We use be going to to express:

  • Decision made before the moment of speaking, already planned events or activities;
  • Predictions based on evidence about the near future.


Future simple (will) and be going to are two forms of the future tense, which differ in meaning and form.

  • We use the future simple to express predictions, beliefs or intentions about the future.
  • We use be going to to express commands, predictions and things that are about to happen.

For example:
— “This printer will probably cost you 70 euros. I heard that it is the usual price.” = We are not certain about the price, we’re just making a guess and therefore we use future simple.
— “This printer is going to cost 70 euros. I checked the price tag.” = We are certain about the price, therefore we use be going to.

NOTE: Certain situations require the be going to structure, whereas others require the future simple.

Let’s revise this content within the {Form} section. Take a look at the {Example} section that shows its use within a context.
