The future perfect simple - grammar rules

Form

Positive statement: I will have worked, I will have written, He will have worked, He will have written (I'll have worked, He'll have worked)
Negative statement: I will not have worked (I won't have worked), He will not have worked (He won't have worked)
Question form: Will you have worked?
Negative question: Will you not have worked? (Won't you have worked?)

We make it with will + have + past participle. The past participles are different for regular and irregular verbs.

Passive voice: The label will have been removed. The lawns will have been mown. (See more at active and passive voice.)

Use

We use the future perfect simple tense for activities that will be completed before or at a certain time. 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.
