Future Perfect Passive

Future Perfect Passive is used to talk about actions or events that will be finished by a certain moment in the future. When we use this tense we are projecting ourselves forward into the future and looking back at an action that will be completed some time later than now. Passive voice means that the subject of the sentence is acted upon.

• This report will have been written by the 1st of November. 
• The project will have been finished by next month. 

The Future Perfect Passive is not very common in English because it is seldom required by the situation. Besides, it’s better to use active voice in speech and writing. But when it is used, it’s usually followed by a time expression, often with the word ‘by’.

• Don’t worry, all work will have been done by 4 p.m.
• We are late. By the time we arrive to the stadium, the game will have been finished.
• All guests will have been brought to the event before it starts.

When to use Future Perfect Passive

The Future Perfect tense is only suitable for actions that will be completed before a specified point in the future. Therefore, the action you’re talking about must have a deadline. If there’s no deadline, we should use Future Simple Passive instead of Future Perfect Passive.

• We will have been given our school certificates by then.
• We will be given our school certificates tomorrow.
