How to Use Future Perfect Continuous Tense for English

Updated: Jan 10, 2022

Brief Overview of the Tense

The Future Perfect Continuous Tense is used to indicate that an action will continue up until a particular event or time in the future. By using this tense, we are projecting ourselves forward in time and looking back at the duration of that activity. The tense consists of

Will + have + been + the verb’s present participle (verb root + -ing)


  • At two o’clock, I will have been waiting for half an hour.

  • In August, I will have been studying German for two years

All grammar rules for forming the tense

  1. For the questions that can be answered as yes or no, we follow-

Yes/No Sentences = Will + Subject + have been + 1st Verb+ ing+ Object?


  • Will you have been solving all the math questions?

  1. For the questions that start with wh words (when, why, who, where, whom, how, what, how much, how many), we follow-

WH Sentences = Wh word + will (Helping Verb) + Subject + have been (Auxiliary verb) + 1st Verb+ ing+ Object.


  • Where will you have been playing Football?

  • Why will she have been sending me these messages?

3. For the Tag questions we add auxiliary verbs
