Spanish future: two useful routes
Choose between a conjugated future and a plan already taking shape.
Spanish often talks about the future without using a future-tense ending. Ir a + infinitive is especially common for intentions and plans; the simple future has its own uses for predictions, formal statements, and conjecture.

The idea
Understand the choice, not just the label.
Form the simple future by adding endings to the full infinitive: hablaré, comerás, vivirán. The endings are shared across -ar, -er and -ir verbs. Several high-frequency verbs use a changed stem, such as tener → tendré, salir → saldré and hacer → haré.
Ir a + infinitive uses a present form of ir, the preposition a and an infinitive: Voy a llamar (I’m going to call). It is a natural choice for intentions and plans. The simple future can also describe plans, and the difference is often about framing rather than a strict timeline boundary.
The simple future can express a prediction (Mañana lloverá) or conjecture about the present (¿Dónde estará Luis? — I wonder where Luis is). A present-tense schedule can also refer to the future: El tren sale a las ocho.
| Form / pattern | Use it when… | Example |
|---|---|---|
| Simple future | future ending attached to the infinitive | Mañana llamaré al dentista. — Tomorrow I’ll call the dentist. |
| Ir a + infinitive | intention or plan | Voy a llamar ahora. — I’m going to call now. |
| Present for a schedule | fixed timetable or arrangement with a time marker | El museo abre el martes. — The museum opens on Tuesday. |
| Future as conjecture | guess about what is true now | Estará en casa. — He’s probably at home. |

Questions about spanish future: two useful routes
Is ir a + infinitive more common than the simple future?
It is very common in conversation, especially for intentions, but both forms are normal. Choice depends on context, register and how the speaker frames the event.
