The future tense is used to talk about events in the future. There are a number of different verb forms‏‎ we can use to talk about the future.

Present Continuous

This is very common. We use the present continuous to talk about plans for the future, often with an adverb of time.

I am going tomorrow.

She is coming next week.

See the main article, Present Continuous‏‎.

Future Simple

The future simple is made with will or be going to and is used to talk about events in the future:

I will go to Spain tomorrow.

I am going to see my Aunt in Madrid.

See the main article, Future Simple‏‎.

Future Continuous

The future continuous, on the other hand, suggests that an event will start at some time in the future but there’s no set finish time yet. Like the other continuous tenses, it’s often used to set the scene before it is interrupted by a simple verb:

If you don’t hurry up they will arrive and you will still be be getting dressed!

I will be waiting at the train station for you.

See the main article, Future Continuous‏‎.

Future Perfect Simple

We use the future perfect simple to talk about an action that will be completed sometime in the future before another action takes place. So the future perfect simple action happens and then finishes and then another action happens:

She will have finished by the time you arrive.

We will have been married 20 years next August.

See the main article, Future Perfect Simple‏‎.

Future Perfect Continuous

The future perfect continuous is very similar to the simple future perfect except it adds a suggestion of progressiveness to the event; it is continuous and will not necessarily finish:

You will have been working here for 10 years at the end of this month.

They will have been living together for 20 years next August.
