In the intricate world of language rules and tenses, the future perfect tense stands out as a unique tool for looking ahead, but with a backward glance. It enables us to express actions that will be completed at a specific point in the future. In this way, the future perfect creates a bridge between the present and a future moment. This article will thoroughly explain this tense by providing its structures, examples, and exercises.

Future perfect in a nutshell

Future perfect allows us to envision completed actions that haven’t happened yet, but will be completed in the future. It is often used to talk about deadlines or achievements.

Definition: Future perfect

The future perfect tense is a verb tense that refers to actions that will have been completed before or by a certain point in the future. It employs two essential auxiliary verbs, combined with the past participle of the main verb. This tense allows the speaker to project themselves into the future and describe a completed action relative to another future action or retrospective time. This tense essentially conveys the idea that an action is already finished by a future moment, typically used when discussing deadlines, plans, or goals.

Examples

  • By this time next year, I will have completed my degree.
  • They will have left the city before the meeting starts.
  • By 10 o’clock, she will have finished cooking dinner.

Formula of future perfect active voice

The future perfect tense belongs to one of the three perfect tenses – which include the past perfect and the present perfect tenses. Unlike the present or past tenses, there is no subject-verb agreement variation since the auxiliary verb “will” stays the same for all subjects and pronouns, whether singular or plural. The past participle (3rd past form) of the relevant verb, however, depends on whether the verb is regular or irregular. You can learn more about these irregular verbs conjugations in our past simple article. The structure of the active form is outlined in the following:

Structure

Subject + will have + past participle + rest of the sentence.

Examples

Examples

  • She will have finished her project by tomorrow.
  • We will have completed the task by the time they arrive.
  • They will have left for vacation before the office party.

Instead of “will,” “shall” can be used in very formal situations. Similar to future simple, this is rarely the case in social contexts, as the use of “shall” is very archaic.

Active question form of future perfect

To form questions in the active future perfect, the auxiliary verb “will” is moved to the beginning of the sentence, followed by the subject, the rest of the formula, and a question mark.

Structure

Will + subject + have + past participle + rest of the sentence?

Examples

Examples

Statement Question
She had already eaten breakfast. Had she already eaten breakfast?
They had left the hotel early. Had they left the hotel early?
We had finished the report on time. Had we finished the report on time?
I had forgotten my keys. Had I forgotten my keys?

Negative question form of future perfect

In the negative question form of future perfect, “not” is inserted after “will,” often in its contracted form as “won’t.” When using question words, you simply add them to the beginning of the sentence.

Structure

Will + subject + not + have + past participle + rest of the sentence?

Or

Won’t + subject + have + past participle + rest of the sentence?

Examples

Examples

  • Won’t she have finished the thesis by tomorrow?
  • Will they not have arrived by the time we get there?
  • Won’t you have completed the assignment by the deadline?

Formula of future perfect passive voice

In the passive voice, the future perfect construction focuses on the action being completed and not on who performed the action. When people are involved, we add the “by” agent right before the object. The passive future perfect formula changes slightly by adding in the auxiliary verb “been” before the main verb. The passive future perfect forms follow the following structures.

Structure

Subject + will have + been + past participle (+ by agent) + object.

Examples

Examples

  • The project will have been completed by next week.
  • The budget will have been approved before the end of the quarter.
  • By next week, the invitations will have been mailed to them.

Structure

Subject + will not + have been + past participle (+ by agent) + object.

Or

Subject + won’t + have been + past participle (+ by agent) + object.

Examples

Examples

  • The renovations won’t have been finished before the holidays.
  • The contract will not have been signed by the time the meeting starts.
  • The papers won’t have been reviewed by tomorrow.

Structure

Will + subject + have been + past participle (+ by agent) + object?

Examples

Examples

  • Will the documents have been translated by Monday?
  • Will the event plan have been finalized by the time we meet?
  • Will the homework have been graded before the weekend?

Structure

Will + subject + not have been + past participle (+ by agent) + object?

Or

Won’t + subject + have been + past participle (+ by agent) + object?

Examples

Examples

  • Won’t the new policy have been implemented by next month?
  • Will the project not have been completed by Sunday?
  • Won’t the report have been delivered before the meeting?

Indicators of the future perfect

Certain time expressions are commonly used with the future perfect to establish a future point by which an action will have been completed. These time markers help specify when the action will be finished.

This indicates that the action will be completed before or by a specific future time of reference.

Examples

  • By next year, I will have moved to a new city.
  • She will have finished the project by Friday.
  • They will have learned the material by the end of the course.

This time marker indicates the duration in which an action will be completed.

Examples

  • They will have built the house in six months.
  • I will have finished reading the book in two days.
  • We will have saved enough money in a year.

This preposition is used when an action is completed prior to another event.

Examples

  • She will have left before the meeting starts.
  • He will have arrived before dinner.
  • They will have completed the course before graduation.

This indicates an action that will be completed immediately following another action.

Examples

  • As soon as you arrive, we will have finished setting everything up.
  • As soon as they finish the presentation, I will have submitted the report.
  • As soon as the train arrives, they will have packed all their bags.

“When” is used to indicate a specific future event that triggers the completion of an action.

Examples

  • When you get home, I will have finished cooking dinner.
  • When the guests arrive, we will have finished setting up the venue.
  • When you read this, I will have left for the airport.

This preposition emphasizes that something will have been completed earlier than expected.

Examples

  • By the time you arrive, she will have already left.
  • When you read this article, I will have already written it. How odd.
  • They will have already sold out of tickets by the time we arrive.

In the future perfect, it is used to underline a point in the future from the current moment.

Examples

  • In two weeks from now, they will have finished the project.
  • In three days from now, we will have been to ten countries.
  • One year from now, she will have completed her degree.

However, there is something that should be noted for the second example.

Note: The future construction using the auxiliary verb “to be” can be easily confused with the future perfect continuous tense, so be careful when using it. E.g., “We will have been married” implies a state of being married, which fits the continuous aspect, even though it uses the structure of future perfect.

Future perfect vs. future simple

Both future perfect and future simple tenses refer to actions or events that happen in the future, but they differ in how they describe the timing and completion of these events.

Future perfect

The future perfect tense (orange) is used to describe an action that will be completed by a specific point in the future. It emphasizes that the action will have been finished before a certain future time or event.

Future simple

The simple future tense (purple) is used to describe actions that will happen in the future without any specifics. It focuses primarily on decisions, promises, or actions that will take place.

Examples

  • I will clean my room tomorrow.
  • I will have cleaned my room by the time my parents get home.
  • She will arrive at 7 PM.
  • By 7 PM, she will have arrived.
  • We will finish the presentation tomorrow.
  • We will have finished the presentation by the end of the day.

Future perfect vs. future perfect continuous

The future perfect and future perfect continuous tenses are used to describe actions that will be completed or in progress at a specific point in the future. However, their structures and usage differ quite considerably, making them easy to not mix up.

Future perfect continuous

This continuous tense’s emphasis is on the duration or continuation of an action up to a certain point in the future. It illustrates that something will have been in progress by using the present participle of the main verb.

Structure

Subject + will have been + present participle + rest of the sentence.

Examples

Examples

  • I will have been working on the report for three hours by the time you arrive.
  • By Friday, she will have been studying for 11 hours straight.
  • They will have been traveling for three weeks by the time they reach their final destination.
