Future Perfect and Other Forms
When discussing the future tense, it’s important to remember that the auxiliary verb “will” must be used. In this article, we will talk about events that will have been completed at a certain time in the future.
will + have + V3: This means that “will” is always used with “have,” and the verb must be in its third form (past participle).
For all subjects (I, you, we, they, she, he, it):
Subject + will + have + V3
As can be deduced from the table above, the question form is created by placing “will” at the beginning.
Will you have finished the work?
For future actions and situations that will have been completed at a specific time, we can specify the time using the preposition “by.” Here are more examples:
By the end of this month, we will have paid our debts. (By the end of the month)
This time next month, the government will have stated its debts. (Next month at this time)
Will all people have finished their business in the fair?
Notice that in all sentences, “will” and “have” auxiliary verbs are mandatory.
I don’t think the lessons will have finished by 4:00.

For example:
Today is Sunday, what will you have done by the end of next month?
