Portuguese Future Perfect: 'Will Have Done' (Futuro Composto)
Grammar Rule in 30 Seconds
The Future Perfect describes an action that will be completed before another point in the future.
- Use 'ter' in the simple future + past participle: 'Eu terei feito'.
- Always use the past participle of the main verb (e.g., 'falado', 'comido').
- It often pairs with 'até' (by/until) or 'quando' (when) to set a time limit.
Overview
The Portuguese Future Perfect (Futuro do Presente Composto or simply Futuro Composto) is a compound tense used to describe an action that will be completed before a specific point in the future. It's the equivalent of the English "will have done." For a B2 learner, mastering this tense is crucial for moving beyond simple future statements and expressing complex, sequenced timelines with precision.
The core function of the Futuro Composto is to establish anteriority (a state of being prior) in relation to a future reference point. Imagine you're projecting yourself forward to a future moment—a deadline, another event, a specific time—and then looking back from that point to an action that has already concluded. The Futuro Composto is the tool for describing that concluded action.
This contrasts sharply with the simple future (Futuro do Presente Simples), which only indicates that an action will happen. The Futuro Composto emphasizes the state of completion of an action at a future time. For example, Eu lerei o livro (I will read the book) is a simple promise.
But Amanhã à noite, eu terei lido o livro (By tomorrow night, I will have read the book) confirms its completion relative to a deadline.
Its structure relies on an auxiliary verb—almost always ter (to have) in modern Portuguese—conjugated in the simple future, followed by the main verb's past participle. This structure allows the auxiliary to handle the tense and subject, while the participle conveys the action itself. Understanding this pattern unlocks a more sophisticated way to discuss plans, predictions, and future states.

How This Grammar Works
Futuro Composto operates on a simple but powerful principle: Action A will be finished before Future Point B. This structure always involves two distinct future time references, even if one is only implied.- 1Future Point B: This is your anchor in the future. It can be a specific time (
às 20h), a deadline (até sexta-feira), or another future action (quando você chegar). - 2Action A: This is the event described by the
Futuro Compostoverb. Its key feature is that its completion happens before or by the time of Future Point B.
NOW ----------- [Action A FINISHES] ----------- [Future Point B] -----------> FUTUREFuturo Composto describes [Action A FINISHES]. Let's see it in practice:Quando o filme começar, nós já teremos comido a pipoca.- Future Point B:
Quando o filme começar(When the movie starts). - Action A:
nós já teremos comido a pipoca(we will have already eaten the popcorn). - The eating of the popcorn concludes before the movie begins.
A Ana não atende o telefone. Ela já terá saído de casa.(Ana isn't answering the phone. She must have already left home.)- Here, the speaker is making a logical deduction about a past action (
sair de casa) using a future tense structure. This is a highly common and nuanced use case for B2 learners to master.
Formation Pattern
Futuro Composto is straightforward and consistent. You don't need to worry about complex exceptions beyond irregular past participles.
Eu, você, ele, ela, nós, vocês, eles, elas.
ter (Simple Future): This part of the verb phrase changes to match the subject. You must know the simple future endings for -er verbs: ter + ei, ás, á, emos, eis, ão.
eu → terei
você/ele/ela → terá
nós → teremos
vocês/eles/elas → terão
-ar, add -ado. (falar → falado)
-er, add -ido. (comer → comido)
-ir, add -ido. (partir → partido)
terminada, terminados, or terminadas in this compound tense. For example: Eles terão terminado (correct) not Eles terão terminados (incorrect).

abrir | aberto | Amanhã, a loja já terá aberto às 9h. |
cobrir | coberto | Até o inverno, a neve terá coberto as montanhas. |
dizer | dito | No final da reunião, ele terá dito tudo. |
escrever | escrito | Daqui a um mês, eu terei escrito o primeiro capítulo. |

pôr | posto | Quando você voltar, eu já terei posto a mesa. |
ver | visto | Na próxima semana, nós teremos visto todos os filmes. |
vir | vindo | Até a hora do jantar, todos os convidados terão vindo. |
When To Use It
Futuro Composto means knowing the specific contexts where it's not just correct, but necessary for clear communication. Here are its primary uses.até (by, until), antes de (before), or a clause starting with quando (when).Eu terei terminado meu dever de casa até as 22h.(I will have finished my homework by 10 PM.)Antes de você chegar, nós já teremos preparado o jantar.(Before you arrive, we will have already prepared dinner.)Quando o chefe pedir o relatório, eu já o terei enviado.(When the boss asks for the report, I will have already sent it.)
Daqui a cinco anos, eu terei me formado na universidade.(Five years from now, I will have graduated from university.)No próximo ano, nós teremos vivido aqui por uma década.(Next year, we will have lived here for a decade.)Se você não regar a planta, em uma semana ela terá morrido.(If you don't water the plant, in a week it will have died.)
A luz do escritório está apagada. O pessoal já terá ido embora.(The office light is off. The staff must have gone home already.)Ele não está na sua mesa. Terá ido almoçar.(He's not at his desk. He has probably gone to lunch.)- Compare:
Ele foi almoçar(He went to lunch - a statement of fact) vs.Ele terá ido almoçar(He must have gone to lunch - a supposition).
Com essa atitude, ele não terá aprendido nada no final do curso.(With that attitude, he will have learned nothing by the end of the course.)Se continuarmos assim, teremos destruído o planeta em 50 anos.(If we continue like this, we will have destroyed the planet in 50 years.)
Common Mistakes
- Mistake:
Quando você ligar, eu faço o jantar.or...eu farei o jantar. - Why it's wrong: This suggests the making of the dinner will happen when you call, not before. It creates a sequence error.
- Correction:
Quando você ligar, eu já terei feito o jantar.(When you call, I will have already made dinner.)
ter or haver.- Mistake:
Ela terá comprada as passagens até amanhã. - Why it's wrong: The past participle in active perfect tenses is invariable.
- Correction:
Ela terá comprado as passagens até amanhã.(She will have bought the tickets by tomorrow.)
terá (Future) with teria (Conditional)Terá indicates a certainty about the future, while teria introduces a hypothetical situation (would have). Mixing them up fundamentally changes the meaning.- Mistake:
Amanhã, a esta hora, eu teria chegado a Lisboa. - Why it's wrong: This means "Tomorrow at this time, I would have arrived in Lisbon," which implies the trip is uncertain or not happening. It is a conditional perfect statement.
- Correction:
Amanhã, a esta hora, eu terei chegado a Lisboa.(Tomorrow at this time, I will have arrived in Lisbon.) - This expresses a confident plan.
- Mistake:
Às 21h, eu terei assistido ao filme.(If you mean the movie will still be playing at 9 PM.) - Why it's wrong: This says that at 9 PM, the act of watching is already finished.
- Correction:
Às 21h, eu estarei assistindo ao filme.(At 9 PM, I will be watching the movie.)
Contrast With Similar Patterns
Futuro Composto from similar-sounding tenses is key to using it correctly. This table highlights the crucial differences in meaning.terei feito | Certainty of future completion. An action will be finished before another future point. | Amanhã, terei terminado o relatório. |farei | Certainty of future action. An action will occur in the future (no emphasis on completion). | Amanhã, terminarei o relatório. |teria feito | Hypothetical past completion. An action would have been finished, if a condition had been met. | Se tivesse tido tempo, teria terminado o relatório. |tinha feito | Past completion. An action had been finished before another past point. | Quando ele pediu, eu já tinha terminado o relatório. |- Future Perfect vs. Simple Future: The most important contrast. Use the simple future (
farei) for a future intention. Use the future perfect (terei feito) when the completion before a deadline is the key piece of information.Eu farei= I'll do it.Eu terei feito= It will be done.
- Future Perfect vs. Conditional Perfect: This is about certainty vs. hypothesis.
tereiis a firm prediction or plan.teriais speculative and disconnected from reality, often part of a conditional sentence (Se...).
- Future Perfect vs. Pluperfect: This is a simple timeline shift. Both express anteriority, but one is in the future (
terei feitobefore a future point) and the other is in the past (tinha feitobefore a past point).
