Future perfect simple (I will have worked eight hours)

Future perfect simple: form

We use will/shall + have + the -ed form of the verb.

We use shall only for future time reference with I and we. Shall is more formal than will.

Note: Shall I, shall we and shan’t I, shan’t we in future perfect questions are rare.

Future perfect simple: use

Events finished by a certain time in the future

We use the future perfect form when we look back to the past from a point in the future. We usually use a time phrase, for example by tomorrow, for three years:

Do you think she’ll have seen the doctor by four o’clock?

Next month my parents will have been together for thirty years.

At the end of this month, they will have been in their house for one year.

Next month I will have worked for the company for six years.

I think they’ll have got there by six o’clock.

Won’t she have retired by the end of the year? (more common than Will she not have retired?)
