The future continuous (will be + ‘ing’ form) and the future perfect (will have + past participle) tenses are used to talk about events in the future.

Future continuous

  • Don’t ring at 8 o’clock. I’ll be watching Who Wants to be a Millionaire.
  • This time tomorrow we’ll be sitting on the beach. I can’t wait!

We use the future continuous to talk about something that will be in progress at or around a time in the future.

  • Don’t phone grandma now, she’ll be having dinner.
  • The kids are very quiet. They’ll be doing something wrong, I know it!

These sentences are not about the future but we can use the future continuous to talk about what we assume is happening at the moment.

Future Perfect

  • Do you think you will have finished it by next Thursday?
  • In 5 years time I’ll have finished university and I’ll be able to earn some money at last.

We use the future perfect to say that something will be finished by a particular time in the future.

We often use the future perfect with ‘by’ or ‘in

  • I think astronauts will have landed on Mars by the year 2020.
  • I’ll have finished in an hour and then you can use the computer.

By’ means ‘not later than a particular time’ and ‘in’ means 'within a period of time’. We don’t know exactly when something will finish.

  • I promise I’ll have done all the work by next Saturday.

We don’t know exactly when he will finish the work – maybe Thursday, maybe Friday – but definitely before Saturday.

 Thanks a lot. I really did fail to find anything on the subject even in advanced and proficiency grammar books

I will be learning in new technologies to get my position higher than now. (Future Continuous)
Most lady will be wearing make-up when they go for sitting interview. (Assuming)
I will have to change my job in next year. (Future Perfect with "in")
I will have to start own-business by the year 2020. (Future Perfect with "by")

Hi. I have a question about Future Perfect Continuous.
Is it possible to use 'since' in this tense, like to say that:
In 2020 I will have been living in France since 2017.
I know that since is generally used for the past but is it possible to use it anyhow in a future tense?? Thanks in advance for your answer.

Hello kudlata,

Yes, you can use 'since' with the future perfect continuous – your sentence is perfect! Congratulations!

Hi,
I'm confused by the last example:
"I promise I’ll have done all the work by next Saturday."

Can I say: "I promise I'll finish all the work by next Saturday. " ?

What's the difference?

Thanks!
Daisy

Hello cleaner,

Yes, you can say that. The two forms take slightly different perspectives on the event, but they mean the same thing. The form you asked about (with 'will') is more commonly used than the future perfect form.

hi..
can i say "I think Alex will leave the quiz?" it doesn't satisfy any parallelism. 'think' is in the present tense and 'will leave' is in future. Is there anything wrong in my judgment? Kindly correct me please

Hello wisefool,

Yes, that's a correctly formed sentence. It uses 'will' to make a prediction about the future.
