Positive statement: I will have worked (I'll have worked), he will have written (he'll have written)

Questions: Will you have cleaned? Will she have sent?
Negative questions: Will you not have cleaned? (Won't you have sent?)

We make the simple tense with will + have + past participle. The past participles are different for regular verbs and irregular verbs. See also how to make the future perfect in the passive.

Use

In the English language we use the future perfect simple tense for activities that will be completed before or at a certain time in the future. It is often used with a time expression beginning with by: by then, by that time, by midnight, by the end of the year ... On the other hand, you must be careful with other time expressions, because this tense cannot be used in time clauses with expressions such as when, while, before, after, as soon as, if, unless, etc., which are normally used in the time clauses with other tenses.

The time can also be given by other time expressions (on Sunday, before 31 June) or actions.

I will have sent the project by Friday.
On 11 August this year we will have been married for five years.
When the mountaineers get back to the base, they'll have been in the snowstorm for two days.
We'll have reached the top before noon.
How long will she have worked here by the end of this year?

In all these examples, at a given time the actions will be in the past.

Positive statement: I will have been writing (I'll have been writing), he will have been studying (he'll have been studying)
Negative statement: I will not have been doing (I won't have been doing)
Questions: Will you have been travelling?
Neg. questions: Will you not have been dancing? (Won't you have been dancing?)

We use the future perfect continuous tense for activities that will continue until a point of time and will not be completed. It is also normally used with by or other time expressions and future events.

I'll go home on 20 June. By then I'll have been staying at this hotel for a fortnight.
At six o'clock we'll have been waiting here for three hours.
When you arrive, we'll have been sitting in the classroom all day.

Compare the simple and continuous tense

The continuous tense is used for incomplete, uninterrupted actions. If we refer to a number of individual events or events that were repeated, we must use the simple.

When I am sixty, I'll have been building houses for thirty years. (one incomplete activity)
When I am sixty, I'll have built more than fifty houses. (fifty individual actions)
By 5 o'clock I'll have been washing this car for an hour and a half. (one uninterrupted activity)
By 5 o'clock I'll have washed this car and replaced the tyres. (two completed activities that will be done one after another)

In this respect they are similar to other English tenses, which you can study on this website to get more examples.
