Grammar Rule in 30 Seconds
Use the Future Perfect to talk about an action that will be completed before a specific point in the future.
- Use 'ter' in the future simple + past participle: 'Eu terei terminado'.
- The past participle usually ends in -ado (ar) or -ido (er/ir).
- It expresses certainty about a future completion: 'Até lá, eu terei chegado'.
Overview
Eu terei terminado o projeto até sexta-feira.
, you are asserting that the project's completion will precede Friday. The emphasis is on the state of completion relative to a future deadline. This construction reflects a nuanced understanding of chronology, enabling precise communication about future eventualities that hinge on prior actions.Conjugation Table

How This Grammar Works
(A), a future point is (C), and the action described by the Future Perfect occurs at (B), which is before (C) but after (A). The speaker positions themselves at (C) and looks back at (B).Quando você chegar, eu já terei saído.
. Here, chegar marks the future reference point (C). The action terei saído (B) will be completed before você chegar.sair is viewed retrospectively from the moment of chegar. This temporal relationship is critical. Without a clear future reference, the Future Perfect often loses its precise meaning or implies a strong assumption.Em 2030, a empresa terá lançado dez novos produtos.
implies that by the year 2030, the cumulative action of launching ten products will be a completed fact, a historical achievement for that future moment. This provides a robust tool for describing future accomplishments, milestones, or even potential future regrets.Formation Pattern
ter (to have) and the past participle of the main verb. However, within Brazilian Portuguese, a more colloquial, three-part alternative is widely used and essential for B2 learners to recognize and employ in informal contexts. European Portuguese primarily uses the two-part structure, occasionally haver.
ter followed by the invariant past participle.
Ter (Future Simple) + Particípio Passado (main verb)
Eu terei visitado (I will have visited)
Ela terá lido (She will have read)
Nós teremos feito (We will have done)
Até o final do ano, a construção terá sido concluída.
(By the end of the year, the construction will have been concluded.) The auxiliary ter carries the tense and mood, while the participle conveys the lexical meaning of the action.
ir, the infinitive ter, and the past participle. While grammatically distinct, its semantic function is identical to the formal Future Perfect.
Ir (Present Indicative) + Ter (Infinitive) + Particípio Passado (main verb)
Ir (Present) | Ter (Infinitive) | Main Verb (Past Participle) | Example (estudar) | Translation |
Não se preocupe, eu vou ter resolvido tudo antes que você chegue.
(Don't worry, I'm going to have resolved everything before you arrive.) This form feels more natural and less formal in casual Brazilian interactions. Learners aiming for fluency in BP should prioritize understanding and using this structure in appropriate contexts.
Haver: In European Portuguese, the verb haver can occasionally function as an auxiliary for compound tenses, including the Future Perfect (haverei feito). However, ter is far more prevalent and universally understood across both Portuguese variants.
When To Use It
- With Time Expressions: Use adverbs or phrases denoting a future time or deadline, such as
até(by/until),quando(when),assim que(as soon as),depois que(after),antes que(before). Até amanhã, eles terão assinado o contrato.(By tomorrow, they will have signed the contract.) The signing will be a completed fact by tomorrow.Quando o chefe voltar, já teremos enviado o relatório.(When the boss returns, we will have already sent the report.) The report sending will be finished prior to the boss's return.
He must have... or He probably has... in English.Ele terá esquecido a chave em casa?(Will he have forgotten the key at home? / Do you think he forgot the key at home?) Here, the future perfectterá esquecidoisn't about a future event, but a present inference about a past event. The speaker is mentally projecting to a point where the 'forgetting' would be confirmed or evident.A essa hora, eles já terão chegado ao aeroporto.(By this time, they will have already arrived at the airport.) This expresses a strong assumption about a past completion, viewed from the present. It impliesI assume they have already arrived.
Dentro de cinco anos, terei construído minha casa.(Within five years, I will have built my house.) The emphasis is on the existence of the built house at the five-year mark.
Até minha formatura, terei aprendido três idiomas.(By my graduation, I will have learned three languages.) This clearly states a goal with a completion deadline.
Common Mistakes
Eu farei) indicates an action that will *occur* at a future time. The Future Perfect (Eu terei feito) signifies an action that will be *finished* by a future time.- Incorrect:
(By 6 PM, I will finish the work.) This implies you will *start or be in the process* of finishing at 6 PM.Até às 18h, eu terminarei o trabalho.
- Correct:
(By 6 PM, I will have finished the work.) This correctly conveys that the work will be *complete* before or at 6 PM.Até às 18h, eu terei terminado o trabalho.
Ter:avoir/avere in specific cases), in Portuguese, when ter is the auxiliary verb in compound tenses, the past participle never agrees in gender or number with the subject or direct object. It remains in its masculine singular form.- Incorrect:
(The girls will have arrived tired – with participle agreeing.)As meninas terão chegado cansadas.
- Correct:
(The girls will have arrived tired – participleAs meninas terão chegado cansado.
chegadoremains masculine singular.) - Incorrect:
(Eu terei fazido a tarefa.
fazidois not a valid participle) - Correct:
(Eu terei feito a tarefa.
feitois the correct irregular participle offazer).
terei) in Informal Contexts (especially BP):terei) in highly casual Brazilian Portuguese conversations can sound overly formal, even archaic. It might give the impression of a stiff or unnatural speaker.- Considered Stiff in BP Casual Speech:
A gente terá saído antes da festa.
- More Natural in BP Casual Speech:
A gente vai ter saído antes da festa.
ter.- Incorrect (missing auxiliary):
(Simple future, lacks the nuance of completion by a future point).Eu estudarei tudo antes do exame.
- Correct:
Eu terei estudado tudo antes do exame.
- Incorrect (infinitive):
Eles terão ver o filme.
- Correct:
(Eles terão visto o filme.
vistois the irregular participle ofver).
abrir -> aberto, dizer -> dito, fazer -> feito, escrever -> escrito, pôr -> posto, ver -> visto). Failure to use the correct irregular form is a common mistake.Contrast With Similar Patterns
- Simple Future (
viajarei,farei): Indicates an action that will take place *at some point* in the future. It states a future intention or prediction without emphasizing prior completion. Eu viajarei em maio.(I will travel in May.) — The act of traveling happens in May.Nós faremos o jantar depois.(We will make dinner later.) — The dinner-making will occur later.- Future Perfect (
terei viajado,terei feito): Indicates an action that will be *completed before* a specific future point. The focus is on the state of completion. Em maio, eu já terei viajado.(In May, I will have already traveled.) — The traveling will be concluded by May.Até as dez, já teremos feito o jantar.(By ten, we will have already made dinner.) — The dinner will be fully prepared by ten.
- Conditional Perfect (
teria viajado,teria feito): Expresses a hypothetical or unrealized action in the past. It describes what *would have happened* under different circumstances, often implying regret or missed opportunity. Eu teria viajado se tivesse dinheiro.(I would have traveled if I had had money.) — The traveling did not happen.Ele teria me ligado se soubesse.(He would have called me if he had known.) — He did not call.- Future Perfect (
terei viajado,terei feito): Expresses a *certain* completion before a future point. It describes a future reality, not a hypothetical past. Até o próximo ano, terei viajado para a Europa.(By next year, I will have traveled to Europe.) — This is a firm prediction or goal.Quando ele voltar, já terei ligado para ele.(When he returns, I will have already called him.) — This is a definite future sequence of events.
- Pluperfect (
tinha viajado,tinha feito): Describes an action completed *before another past action*. The reference point is in the past. Quando cheguei, ele já tinha viajado.(When I arrived, he had already traveled.) — Both actions are in the past, the traveling occurring first.Nós tínhamos terminado o trabalho antes que a chuva começasse.(We had finished the work before the rain started.) — Work finished before a past event.- Future Perfect (
terei viajado,terei feito): Describes an action completed *before a future action*. The reference point is in the future. Quando você chegar, ele já terá viajado.(When you arrive, he will have already traveled.) — Traveling will be complete before a future arrival.Teremos terminado o trabalho antes que a chuva comece.(We will have finished the work before the rain starts.) — Work will be finished before a future event.
Real Conversations
Observing the Future Perfect in authentic contexts reveals its utility in diverse registers, from casual planning among friends to more formal project updates.
1. Setting Future Deadlines / Goals (Formal & Informal):
- Work Email: (Dear all, by the end of the day, all financial reports will have been processed.) — Formal, emphasizing a completed task.Prezados, até o fim do dia, todos os relatórios financeiros terão sido processados.
- Team Meeting (BP): (Don't worry, we're going to have resolved this logistics issue before the client meeting.) — Colloquial, reassuring.Não se preocupem, a gente vai ter resolvido essa questão da logística antes da reunião com o cliente.
- Personal Goal: (Next year, I will have run a marathon.) — A personal achievement by a future point.Ano que vem, terei corrido uma maratona.
2. Making Assumptions / Inferences (Common in BP):
- Text Message (BP): (João hasn't arrived? He must have hit heavy traffic.) — A present inference about a past cause.O João não chegou? Ele vai ter pego o trânsito pesado.
- Casual Conversation (EP): (By this time, they will have already finished the movie.) — A likely assumption about a current state based on past action.A esta hora, já terão terminado o filme.
3. Planning and Coordination:
- (When you call back, we will have already decided the trip date.) — Coordinating future actions.Quando você ligar de volta, já teremos decidido a data da viagem.
- (If we don't finish today, by tomorrow morning we will have lost a lot of time.) — Expressing a future negative consequence.Se não terminarmos hoje, amanhã de manhã teremos perdido muito tempo.
These examples underscore how the Future Perfect allows speakers to frame future events with a backward-looking perspective, whether to confirm an outcome, speculate on a cause, or establish a definitive timeline for completion. The choice between formal terei and informal vou ter depends entirely on the context and relationship with the interlocutor.
Progressive Practice
Mastering the Future Perfect requires consistent and varied practice. Focus on exercises that encourage you to conceptualize future completion and apply both formal and informal constructions correctly.
- Transform Sentences: Take sentences in the Simple Future and rewrite them using the Future Perfect, introducing a future time marker (até, quando, etc.). Example: -> Eu escreverei o artigo.
Até o final da semana, eu terei escrito o artigo.
- Complete the Scenario: Provide a future scenario and ask yourself what actions will have been completed by that time. Focus on diverse verbs, especially those with irregular participles. Example: (Answer: Você tem um exame na próxima semana. O que você vai ter feito até lá?
)Eu vou ter revisado todas as matérias.
- Role-Playing: Engage in dialogues where you need to coordinate future events, set deadlines, or make assumptions about what will have happened. Practice using both formal (terei) and informal (vou ter) auxiliary forms depending on the role and context.
- Identify Correct Usage: Analyze texts or dialogues, identifying instances of the Future Perfect and explaining *why* it was used instead of the Simple Future or another tense. Pay attention to the explicit or implied future reference point.
- Self-Correction with Feedback: Record yourself speaking or write short paragraphs. Then, review your work, specifically checking for correct Future Perfect usage and participle forms. Seek feedback from native speakers or instructors.
Quick FAQ
haver ever used instead of ter for the Future Perfect?While grammatically possible (haverei feito), particularly in more traditional or literary European Portuguese, ter (terei feito) is overwhelmingly the preferred and more natural auxiliary verb across all variants of Portuguese for forming the Future Perfect. Stick with ter for everyday communication.
ter is the auxiliary?No. When ter functions as the auxiliary verb in compound tenses, the past participle always remains in its invariable masculine singular form. This is a fundamental rule in Portuguese. For example, (not Ela terá *lido* o livro
*lida*), and (not Eles terão *feito* a tarefa
*feitas*). This contrasts with some other Romance languages, so be mindful not to transfer those rules.
vou ter feito form in Brazilian Portuguese?In spoken, informal Brazilian Portuguese, the vou ter feito construction is very common and natural. However, for formal writing, academic contexts, or interactions requiring a higher degree of formality (e.g., business emails, official documents), the standard terei feito form is generally expected and more appropriate. Choose your auxiliary based on the register and audience.
Eu terei feito and Eu farei?The crucial distinction lies in the aspect of completion. Eu farei (Simple Future) means
I will do/makeat some point in the future.
Eu terei feito (Future Perfect) means I will have done/madeby a specific future time, emphasizing that the action will be *completed* before or at that future point. The Future Perfect explicitly points to a state of prior accomplishment relative to a future moment.
Eu farei o jantar às 20h
means you'll cook at 8 PM. Até às 20h, eu terei feito o jantar
means dinner will be ready by 8 PM.
While both refer to future events, the Future Perfect expresses a *certainty* of completion relative to a future point, or a strong inference. The Future Subjunctive (Quando eu *fizer*) expresses a *condition* or *contingency* for a future event. For instance, (Future Perfect, certainty of completion) vs. Quando eu tiver terminado o relatório, irei para casa.
(Future Subjunctive, contingency – *if* I finish it). The Future Perfect implies a higher degree of assurance regarding the completion of the action by the specified future time.Quando eu terminar o relatório, irei para casa.
