In Spanish there are two main ways to express the future: the immediate future using ir a + infinitive (equivalent to "going to" in English) and the simple future tense (futuro simple). Understanding when to use each — and mastering the conjugations — gives you the ability to make plans, predictions and offers in natural, flowing Spanish.

The Immediate Future: Ir a + Infinitive

This is the most commonly used future construction in everyday spoken Spanish — equivalent to "going to" in English. It describes plans, intentions and near-future events:

Formula: present tense of ir + a + infinitive

Present of Ir+ a + InfinitiveExample
voya estudiarVoy a estudiar esta noche. — I am going to study tonight.
vasa comer¿Vas a comer aquí? — Are you going to eat here?
vaa llegarVa a llegar tarde. — She is going to arrive late.
vamosa visitarVamos a visitar España. — We are going to visit Spain.
vaisa hacer¿Qué vais a hacer? — What are you going to do?
vana salirVan a salir pronto. — They are going to leave soon.

When to Use Ir a + Infinitive

  • Plans and intentions already decided:
    Esta noche voy a cenar con mis amigos. — Tonight I am going to have dinner with my friends.
  • Near future events:
    Va a llover esta tarde. — It is going to rain this afternoon.
  • What you are about to do:
    Vamos a empezar la clase. — We are going to start the class.
  • Predictions based on visible evidence:
    Mira las nubes — va a tormentar. — Look at the clouds — it is going to storm.

The Simple Future Tense (Futuro Simple)

The simple future is used for more distant future events, predictions not based on immediate evidence, promises and offers. It is formed by adding endings directly to the infinitive — making it one of the easiest tenses to form in Spanish.

Regular Future Tense Conjugation

The same endings apply to ALL verbs — -AR, -ER and -IR — added to the complete infinitive:

    En 2050, habrá más de diez mil millones de personas en el mundo. — In 2050, there will be more than 10 billion people in the world.
  • Expressing probability about the present (conjectural future):
    ¿Dónde estará Juan? — Estará en casa. — Where is Juan? — He is probably at home.
    Tendrá unos cuarenta años. — He must be about forty years old.
  • After si (if) — only with si + present:
