Futur Proche vs Futur Simple
French has two everyday futures, and both are correct: the futur proche (aller + infinitive, "going to do") presents an event as close, decided, or connected to now, while the futur simple (je partirai, "I will leave") presents it as more distant or detached — predictions, promises, formal plans. In conversation, the futur proche is the default; in writing, forecasts, and announcements, the futur simple takes over.
Most of the time this is a matter of flavor, not law: either form is grammatical, and what changes is how the event feels. But a few contexts do force the choice — above all future time clauses after quand and dès que — and those are where learners lose points. This page gives you the decision criteria, the signal words, and the one hard rule.
In short
- Futur proche (
je vais partir) = near, decided, already on its way — the default future of spoken French. - Futur simple (
je partirai) = distant, predicted, promised, or scheduled — the default future of written French. - In most sentences both are correct; the choice is about how connected the event feels to now.
- One hard rule: a future time clause after quand or dès que takes the futur simple.

One-line reminder of each form
Reminder: futur proche = present of aller + infinitive; futur simple = one word, stem + -ai/-as/-a/-ons/-ez/-ont. Full formation on the futur proche and futur simple pages.
The core difference: hooked to now, or out on the horizon
Think of the futur proche as a ramp that starts under your feet: from where you stand right now, you are heading toward the event. It is already in motion — you can see it coming, you have decided it, it follows from the present situation.
The futur simple points at a spot on the horizon instead. The event is out there, detached from this moment: a prediction, a promise, a plan on paper.
Careful, you’re going to fall!
— The fall is a second away — the futur proche ties it to right now.
One day, we will perhaps live on Mars.
— A distant, vague prediction sits naturally in the futur simple.
Look at those clouds: it’s going to rain.
— Present evidence — you can see the clouds — launches the futur proche.
According to the forecast, it will rain over the whole region tomorrow.
— A detached forecast about later — no evidence in front of you, just prediction.
Decided plans vs promises and predictions
Distance in time is not the whole story. A wedding nine months away takes the futur proche the moment the decision is made, because the decision anchors it to now. A promise, on the other hand, reaches into the future and leans toward the futur simple — it has the solemn, detached tone of "I will".
Lean futur proche when the event is
- Imminent: about to happen, already visible
- Decided: the plan exists now, whatever the date
- A logical result of the present situation
- Everyday conversation about your plans
Lean futur simple when the event is
- Distant or vague: "un jour", "dans vingt ans"
- A prediction, forecast, or hypothesis
- A promise or commitment
- Scheduled in writing: programs, announcements, official plans
It’s decided: we’re getting married in September.
— The decision is made now, so even a date months away takes the futur proche.
I promise you that I will always be there for you.
— Promises and commitments take the solemn futur simple.
Spoken vs written: a tendency, not a law
In conversation, French speakers reach for the futur proche constantly — it covers most everyday plans, even ones the futur simple would also fit. In newspapers, schedules, weather reports, and formal announcements, the futur simple dominates. Neither form is wrong in the other register; this is a leaning, not a rule, so do not panic when you hear a futur simple over coffee or read a futur proche in an email.
Tonight we’re eating at my parents’ place.
— In conversation, plans default to aller + infinitive.
The store will open its doors on March 3rd.
— Written announcements and schedules prefer the futur simple.
The hard rule: quand and dès que take the futur simple
Here the choice stops being flavor. When a time clause after quand, lorsque, dès que, or aussitôt que refers to the future, standard French puts that clause in the futur simple — not the present (an English habit) and not the futur proche (common in casual speech, but avoid it in standard French).
quand / dès que + futur simple + main clause (futur simple or imperative)
When she gets home, she will call us.
— Both clauses are future in French: the quand-clause must use the futur simple.
Signal words
Some expressions tilt the sentence strongly toward one form. Treat them as hints — the connection-to-now logic always wins — except for the quand family, which is a real rule.
| Leans futur proche | Leans futur simple |
|---|---|
| tout de suite, d’une minute à l’autre | un jour, plus tard, dans vingt ans |
| regarde !, attention ! | d’après la météo, je pense que |
| c’est décidé, c’est prévu | je promets que, je parie que |
Common mistakes
✗Regarde le ciel : il pleuvra d’une minute à l’autre.
✓Regarde le ciel : il va pleuvoir d’une minute à l’autre.
Visible evidence plus "any minute now" hooks the rain to the present moment — exactly what the futur proche expresses. The futur simple here sounds like a forecast about some other day.
✗Dès qu’il va rentrer, on mangera.
✓Dès qu’il rentrera, on mangera.
A future time clause after dès que or quand takes the futur simple in standard French, not the futur proche.
✗Je te promets que je vais t’aimer toute ma vie.
✓Je te promets que je t’aimerai toute ma vie.
A solemn promise reaching into the indefinite future takes the futur simple, not the futur proche.

Frequently asked questions
What is the difference between the futur proche and the futur simple?
Both talk about the future. The futur proche (aller + infinitive) presents the event as close, decided, or connected to now, and dominates spoken French. The futur simple (je partirai) presents it as more distant or detached — predictions, promises, formal plans — and dominates writing.
Can I use the futur proche instead of the futur simple in conversation?
Very often, yes: spoken French uses the futur proche as its default future, even for events months away, as long as they feel decided. The main place you cannot swap is a future time clause after quand or dès que, which takes the futur simple.
Is the futur simple more formal than the futur proche?
As a tendency, yes: the futur simple dominates news, schedules, forecasts, and solemn promises, while the futur proche dominates conversation. But both forms are fully correct in both registers — it is a leaning, not a rule.
Memory tip
Ask one question: is the event hooked to now — visible, decided, already on its way? Then aller + infinitive. Is it out on the horizon — predicted, promised, printed in a program? Then the futur simple. And after quand or dès que, don’t ask: futur simple.
