Future Perfect Tense Formula and Uses


Table of Content(toc)

The future perfect tense has precisely the same meaning as the past perfect, except the time is the future.

Future Perfect Tense Formation

We make the future perfect tense using will have and past participle of the main verb. Be going to is less commonly used instead of will in the future perfect tense.

Structure of Future Perfect Tense

Interrogative Sentences

In the interrogative form of the future perfect tense, we invert the subject with the will. The interrogative sentences can also be made using different question words such as who, when, why, etc.

Structure: Will + Subject + have + past participle + Object
Examples
  • Will your assistant have typed twenty pages by next Friday?
  • Will she still be in the office at 7 o’clock? I will have left by then.
  • Will you have eaten two pieces of bread before drinking tea?
  • Will they have studied three chapters by afternoon?
  • Will they have moved to a new house by next month?
  • Who will have done the presentation by the time I arrive in the class?
  • How much work will they have done by 6 o’clock?
  • Who will have prepared the presentation for the seminar?

Uses of the Future Perfect Tense

The future perfect tense is used to express an action that will be completed at a specific point in the future.

Examples
  • She will have already washed clothes when I reach home.

This sentence means she will finish wash clothes before I get home.

  • We will have learned some English before I join this academy.
  • Before I get home, my mother will have left.
  • By this day next year, I will have completed my degree course.
When we add the length of time to the future perfect tense, it has the same meaning as the future perfect continuous tense.

Example
  • When we finally finish work, I will have slept for three hours. (Future Perfect)
  • When we finally finish work, I will have been sleeping for three hours. (Future Perfect Continuous)

This tense is also used for actions that, at a given future time, will be in the past.

Example
  • In three years I will have got the job.
In this sentence, “in three-year time means” three years from now.

Future perfect is also used to express time expression

Example
  • He will have taught him for two months next week.
The following words describe actions that started in the past and continued into the present.
Since, for, whole, all, how long, etc.

Note: The be going to form is not usually used in the future perfect tense. Using be going to in the future perfect tense is not wrong, but it makes the verb long; therefore, we avoid it.
