The Future in Spanish

Spanish has several ways to talk about the future. The two most important are ir + a + infinitive and the simple future. They can sometimes translate as “going to” and “will” in English, but the difference is not exactly the same.

💡

Everyday Spanish

In conversation, ir + a + infinitive is extremely common. The simple future is also important, especially for predictions, promises, formal or written language, and expressing probability.

Highly Common

1. Ir + a + Infinitive

Commonly used for plans and intentions, things that are already expected to happen, events that are about to happen, and predictions based on present evidence.

Conjugate only 'ir' + a + infinitive

  • yo voy
  • vas
  • él va
  • nosotros vamos
  • vosotros vais
  • ellos van

Voy a estudiar esta noche.

I’m going to study tonight.

¿Vas a venir mañana?

Are you going to come tomorrow?

Mira esas nubes. Va a llover.

Look at those clouds. It’s going to rain.

2. The Simple Future

Formed by adding the future endings directly to the infinitive. Good news: Unlike many Spanish tenses, the endings are exactly the same for -ar, -er, and -ir verbs.

infinitive + future ending

  • yo
  • -ás
  • él
  • nosotros -emos
  • vosotros -éis
  • ellos -án

Estudiaré español.

I will study Spanish.

Mañana trabajaremos desde casa.

Tomorrow we will work from home.

Será difícil.

It will be difficult.

3. 12 Common Irregular Stems

Some very common verbs change their stem, but they still use the exact same future endings (e.g. podr + é → podré).

Infinitive Future Stem Example (yo / él / nosotros)
tenertendr-tendré
venirvendr-vendrás
ponerpondr-pondrá
salirsaldr-saldremos
poderpodr-podréis
quererquerr-querrán
sabersabr-sabré
haberhabr-habrá
hacerhar-haré
decirdir-dirás
valervaldr-valdrá
cabercabr-cabremos

4. Ir + a vs. Simple Future

This is one of the most important distinctions for learners. Both can refer to the future, and often both are grammatically correct. The difference is usually about how the speaker presents the future.

Ir + a + Infinitive

  • • Very common in conversation
  • • Plans and intentions
  • • Expected/imminent events
  • • Predictions based on present evidence
  • • Often sounds more immediate

Voy a estudiar esta noche.

I have this plan / intention.

Simple Future

  • • Common in conversation too
  • • Predictions
  • • Promises and commitments
  • • Formal or written contexts
  • • Can sound more neutral or definite

Estudiaré esta noche.

I will study tonight.

🇬🇧 English connection: Spanish ir + a and the simple future often correspond to English “going to” and “will.” The comparison is useful, but the systems are not identical. Spanish speakers do not choose between them according to exactly the same rules as English speakers.

5. The Future Is Not Only About the Future

One of the most useful features of the Spanish future is that it can express probability or conjecture about the present.

The "Aha!" Moment

¿Dónde está Ana? — Estará en casa.

She is probably at home.

Here, estará does NOT mean "she will be at home." It means: She is probably at home right now.

¿Qué hora será?

I wonder what time it is.

Serán las ocho.

It’s probably eight o’clock.

¿Por qué no contesta?

Why isn't he answering?

Estará trabajando.

He is probably working.

6. Common Uses of the Simple Future

🔮 Predictions

Mañana hará frío.

It will be cold tomorrow.

🤝 Promises / Commitments

No te preocupes. Lo haré.

Don’t worry. I’ll do it.

📅 Future events

El próximo año viviremos en México.

Next year we will live in Mexico.

📢 Formal/Written

El gobierno anunciará las medidas.

The government will announce the measures.

🤔 Probability / Conjecture

Estará ocupado.

He is probably busy.

7. Time Expressions

  • mañana tomorrow
  • pasado mañana day after tomorrow
  • la próxima semana next week
  • el próximo mes next month
  • el año que viene next year
  • dentro de dos días in two days
  • algún día someday
  • más tarde later
  • en el futuro in the future

8. Future Perfect (A Quick Look)

Used for an action that will already be completed by a future moment, or to guess about a past action.

haber (future) + past participle

Para las ocho, habré terminado.

By eight, I will have finished.

¿Dónde está Ana? Habrá salido.
