Adults|Grammar|Intermediate|16. I will and I’m going to

Study the difference between will and (be) going to:

Future actions

Sue is talking to Helen:



— Let’s have a party.
— That’s a great idea. We‘ll invite lots of people.

Will (‘ll): We use will when we decide to do something at the time of speaking. The speaker has not decided before. The party is a new idea.


Later that day, Helen meets Dave:


— Sue and I have decided to have a party. We‘re going to invite lots of people.

(be) going to: We use (be) going to when we have already decided to do something. Helen had already decided to invite lots of people before she spoke to Dave.



1. «Gary phoned while you were out.» «OK. I‘ll call him back.»

«Gary phoned while you were out.» «Yes, I know. I’m going to call him back.»

2. «Ann is in hospital.» «Oh really? I didn’t know. I’ll go and visit her.»

«Ann is in hospital.» «Yes, I know. I’m going to visit her this evening.»

Future happenings and situations (predicting the future)

Sometimes there is not much difference between will and going to. For example, you can say:

1. I think the weather will be nice this afternoon.

2. I think the weather is going to be nice this afternoon.

When we say something is going to happen, we think this is because of the situation now. For example:

1. Look at those black clouds. It’s going to rain. (not It will rain)

(We can see that it is going to rain from the clouds that are in the sky now.)

2. I feel terrible. I think I‘m going to be sick. (not I think I’ll be sick)

(I think I‘m going to be sick because I feel terrible now.)

Do not use will in this type of situation.

In other situations, use will:

1. Tom will probably get here at about 8 o’clock.

2. I think Sarah will like the present we bought for her.

3. These shoes are very well-made. They‘ll last a long time.

Read the rules

We use the present continuous (I’m doing) for arrangements:

1. I‘m leaving tomorrow. I’ve got my plane ticket. (already planned and arranged)

2. «When are they getting married?» «On 24 July.»

We use the present simple (I leave / it leaves etc.) for timetables, programmes etc.:

1. My train leaves at 11.30. (according to the timetable)

2. What time does the film begin?

We use (be) going to … to say what somebody has already decided to do:

1. I’ve decided not to stay here any longer. I‘m going to leave tomorrow. (or I‘m leaving tomorrow.)

2. «Your shoes are dirty.» «Yes, I know. I‘m going to clean them.»

We use will (‘ll) when we decide or agree to do something at the time of speaking:

1. — I don’t want you to stay here any longer.
— OK. I‘ll leave tomorrow. (It is decided at the time of speaking)

2. That bag looks heavy. I‘ll help you with it.

3. I won’t tell anybody what happened. I promise. (won’t = will not)


Read the rules

Most often we use will to talk about future happenings («something will happen«) or situations («something will be»):

1. I don’t think John is happy at work. I think he‘ll leave soon.

2. This time next year I’ll be in Japan. Where will you be?

We use (be) going to when the situation now shows what is going to happen in the future:

Look at those black clouds. It’s going to rain. (you can see the clouds now)
