Futur II — future perfect

The last tense on our map. Futur II is what you use to say "by tomorrow I'll have finished" or "by then they'll have arrived." You also use it to voice an assumption about something that has probably already happened. Rare in speech, handy in writing, and once you see the formula there's nothing new to memorize.

The shape

werden (conjugated) + Partizip II + haben / sein (infinitive) — at the end.

Three verb pieces. werden in slot 2, then the participle, then haben or sein as the trailing infinitive. Same auxiliary logic as Perfekt and Plusquamperfekt.

Two jobs Futur II does

1) Completed future event — something that will be done by a specific point in the future.

2) Assumption about the past — the Futur II equivalent of wird wohl.

The "probably" tone is often reinforced by wohl, bestimmt, sicher.

sein vs. haben — same rules as Perfekt

The auxiliary at the end of the sentence follows the same rule you learned for Perfekt.

Speech almost never uses Futur II

In spoken German, you'd usually just say:

• Morgen bin ich fertig. (Präsens + time marker — same meaning as "by tomorrow I'll have finished.")
• Er hat das bestimmt schon gesehen. (Perfekt + bestimmt = same as assumption-style Futur II.)

Futur II shows up mostly in writing, news, and formal registers. Know the form so you can read it.

Subordinate clause position

In a Nebensatz, all three verb pieces go to the end, with werden LAST.

Common mistakes, named

1. Dropping the trailing haben / sein. Bis morgen werde ich das erledigt. ❌ → ... erledigt haben. ✓

2. Using the wrong auxiliary. Er wird angekommen haben. ❌ → Er wird angekommen sein. ✓

3. Using Futur II where Perfekt would do. Er wird das schon gesehen haben — fine in print but in speech you'd just say Er hat das bestimmt schon gesehen.
