Futurum exaktum (Future Perfect)

The futurum exaktum in Swedish is used to describe an action that will have been completed by a certain time in the future.
It can also express assumptions about something that has already been completed when speaking from a present or future perspective.

Mood:

Indicative — used for factual statements, confident predictions, or assumptions about actions that will be completed before a specific point in the future.

Usage:

• To describe actions that will be completed by a certain time in the future:
  Jag ska ha avslutat projektet innan fredag.
  (I will have finished the project before Friday.)
• To make confident predictions about completed events:
  Hon kommer att ha läst boken innan resan.
  (She will have read the book before the trip.)
• To express assumptions about something completed from a future viewpoint:
  Vid det laget har han nog redan åkt.
  (By then, he will probably have already left.)

The futurum exaktum is formed with:

1. ska or kommer att (future auxiliary)

Notes:

• ska is slightly more common in casual speech; kommer att is also correct and often more formal.
• The supinum is the same form used in the perfect tense (har + supinum).
• This tense is mostly used in formal contexts or planned scenarios — in everyday Swedish, speakers sometimes use the present perfect with a future time expression instead.
