Future perfect simple
We make the future perfect simple with will + have + past participle. The past participles are different for regular verbs and irregular verbs (worked, stayed / done, writtten).
Positive statement: I will have worked (I'll have worked), he will have written (he'll have written)
Negative statement: I will not have returned (I won't have returned), he will not have done (he won't have done)
Questions: Will you have cleaned? Will she have cleaned?
Negative questions: Will you not have sent? (Won't you have sent?)
Use
We use the future perfect 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.
The time can also be given by other time expressions (on Sunday, before 31 June) or other 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?
Future perfect in time clauses and if-clauses
You must be careful with expressions such as when, while, before, after, as soon as, if, unless, because the auxiliary verb will cannot be used in time clauses and if-clauses.
I'll leave before you have cooked dinner.
We'll move into the house as soon as they have renovate it.
Betty will help you if you haven't finished the project by Friday.
