French has two main ways to talk about the future, and they live in different registers. The futur proche — aller + infinitive — is the workhorse of spoken French. The futur simple — the synthetic tense with -rai/-ras/-ra endings — is alive in writing, news, formal speech, and a handful of conversational niches. Most beginner textbooks teach the futur simple first because it has a clean morphological story; in real life, the futur proche dominates so completely that getting that one right gets you 80% of the way to natural-sounding French futures.
This page maps the choice in three axes — proximity, register, certainty — and walks through the situations where the choice matters most.
The two forms in one minute
Futur proche: present tense of aller + bare infinitive. Same construction as English be going to + verb.
Je vais partir dans cinq minutes.
I'm going to leave in five minutes.
On va manger quoi ce soir ?
What are we going to eat tonight? (informal)
Futur simple: a single inflected word, formed (for regular verbs) by adding -ai, -as, -a, -ons, -ez, -ont to the infinitive. For parler: je parlerai, tu parleras, il parlera, nous parlerons, vous parlerez, ils parleront.
Demain, il pleuvra dans tout le sud du pays.
Tomorrow, it will rain throughout the south of the country.
Je te promets que je le ferai avant ce soir.
I promise you I'll do it before tonight.
The two forms can describe the same future event — the difference is rarely about when and almost always about how you are framing it.
Axis 1: Register (spoken vs written)
This is the biggest single difference. In conversation, French speakers use the futur proche for nearly all future reference, including events days, weeks, or months away. The futur simple in casual speech sounds slightly elevated or deliberate — not wrong, just marked.
L'année prochaine, je vais déménager à Marseille.
Next year, I'm moving to Marseille. (very natural in conversation, even though it's a year away)
L'année prochaine, je déménagerai à Marseille.
Next year, I will move to Marseille. (correct but more deliberate, more written)
In written and formal French — newspapers, books, official communications, weather forecasts, scientific predictions — the futur simple is dominant. A weather presenter on TV will typically say il pleuvra (futur simple), not il va pleuvoir (futur proche), because the futur simple carries an air of authority and neutral prediction.
Le président s'adressera à la nation à 20 heures.
The president will address the nation at 8 p.m. (formal — news register)
Les températures atteindront 35 degrés cet après-midi.
Temperatures will reach 35 degrees this afternoon. (formal — weather report)
Axis 2: Proximity and certainty
The traditional textbook explanation is that futur proche = near future, futur simple = distant future. This is partly true but oversold. The deeper distinction is certainty grounded in the present moment.
The futur proche presents the action as already in motion now — already planned, already scheduled, already imminent. The path from now to the action happening is visible. The futur simple presents the action as a more abstract assertion about what will be true at some future point, without the same anchoring in the present.
Attention, tu vas tomber !
Watch out, you're going to fall! (imminent — present evidence: you're losing your balance now)
Si tu n'apprends pas à rester debout, tu tomberas.
If you don't learn to stay upright, you'll fall. (general prediction, not anchored to a current moment)
Je vais avoir trente ans en septembre.
I'm going to be thirty in September. (natural in conversation about an inevitable event)
En 2050, beaucoup de villes côtières seront sous l'eau.
In 2050, many coastal cities will be underwater. (distant prediction, no link to a current observable trend)
Both tenses can describe near or distant events. What the futur proche adds is connection to now: a plan you have already made, a trajectory already underway, a piece of evidence already visible.
Axis 3: Speech act and intent
The futur simple has a few residual functions that the futur proche does not perform well.
Promises and commitments
When you make a solemn promise, the futur simple sounds weightier. It is the tense of vows, contracts, and considered commitments.
Je t'aimerai toujours.
I will love you always. (a vow — futur simple essential)
Je te jure que je ne le ferai plus jamais.
I swear I'll never do it again. (futur simple — solemn)
Saying je vais t'aimer toujours is grammatically fine but somehow wrong for the moment — it makes the love sound like a planned activity rather than an enduring state.
Polite imperatives
The futur simple can soften an instruction or request, especially in formal or administrative speech.
Vous voudrez bien nous transmettre les documents avant vendredi.
Kindly send us the documents before Friday. (administrative)
Tu fermeras la porte en partant, s'il te plaît.
Close the door on your way out, please. (gentle instruction — softer than the imperative)
This is hard to replicate with the futur proche, which sounds too immediate and too definite for the polite-instruction register.
Predictions in journalism, history, and forecasting
When the source is impersonal — a forecast, a piece of journalism, a historical analysis — the futur simple is preferred.
Selon les analystes, le marché se redressera dans le courant de l'année.
According to analysts, the market will recover during the year.
Demain, dans notre émission, nous recevrons l'écrivaine Maylis de Kerangal.
Tomorrow on our show, we'll be welcoming the writer Maylis de Kerangal.
The clause-internal cases (where you must pick one)
Some grammatical contexts force a choice. Both are sometimes acceptable, but knowing the convention helps you sound natural.
After si (if-clauses for conditionals)
This is critical. After si meaning if, French uses the présent, never any future tense — neither futur simple nor futur proche.
Si tu viens demain, on ira au cinéma.
If you come tomorrow, we'll go to the movies.
Si tu as faim, je vais te préparer quelque chose.
If you're hungry, I'm going to make you something.
The main clause (on ira / je vais te préparer) can use either futur — but the si clause itself must be présent. See the dedicated page si-with-present-not-future.
After quand, lorsque, dès que, aussitôt que (temporal future)
This is the inverse trap. Where English uses the present in a temporal future clause (when you arrive), French uses the future (quand tu arriveras).
Quand tu arriveras à la gare, appelle-moi.
When you arrive at the station, call me. (note the future tense in French)
Dès qu'il aura fini ses études, il partira en voyage.
As soon as he has finished his studies, he'll leave on a trip. (note: the antériorité takes futur antérieur)
In these temporal subordinate clauses, the futur simple is the standard choice. The futur proche is acceptable in casual speech (quand il va arriver) but sounds slightly informal; the simple future is the safer pick. See quand-aussitot-des-que for full coverage.
Reported speech (future-in-past)
When you report what someone said about the future from a past perspective, French shifts to the conditionnel présent (formerly called the future-in-past).
Il m'a dit qu'il viendrait demain.
He told me he would come tomorrow. (NOT *qu'il viendra)
This is technically off-topic, but it is worth flagging because learners sometimes try to use either future tense here and both are wrong.
Pronoun placement: a small but constant trip-up
With the futur proche, object pronouns go before the infinitive, not before aller.
Je vais le faire ce soir.
I'm going to do it tonight. (NOT *je le vais faire)
Tu vas me le dire ou pas ?
Are you going to tell me or not? (informal — pronouns me + le before the infinitive)
With the futur simple, pronouns go before the conjugated future verb, like in any other simple tense.
Je le ferai demain matin.
I'll do it tomorrow morning.
Vous me le direz quand vous saurez.
You'll tell me when you know.
Negation
For the futur proche, the ne... pas wraps aller, not the infinitive.
Je ne vais pas y aller.
I'm not going to go (there).
On ne va pas attendre plus longtemps.
We're not going to wait any longer.
For the futur simple, ne... pas wraps the conjugated future verb.
Je n'irai pas.
I won't go.
Ils ne comprendront jamais.
They will never understand.

Common mistakes
These five mistakes account for almost all futur-tense misuse by English speakers.
❌ Je vais à partir demain.
Incorrect — French does NOT insert 'à' between aller and the infinitive in the futur proche.
✅ Je vais partir demain.
I'm going to leave tomorrow.
❌ Si tu viendras demain, on ira au cinéma.
Incorrect — never use any future tense after 'si' meaning 'if.' Use the présent.
✅ Si tu viens demain, on ira au cinéma.
If you come tomorrow, we'll go to the movies.
❌ Quand tu arrives à la gare, appelle-moi.
Incorrect — for future temporal clauses, French uses the futur simple, not the présent (unlike English).
✅ Quand tu arriveras à la gare, appelle-moi.
When you arrive at the station, call me.
❌ Je le vais faire ce soir.
Incorrect — in the futur proche, object pronouns precede the infinitive, not 'aller.'
✅ Je vais le faire ce soir.
I'm going to do it tonight.
❌ Je vais t'aimer toujours.
Awkward — solemn promises and enduring states sound much better in the futur simple.
✅ Je t'aimerai toujours.
I will love you always.
Key takeaways
- In conversation, default to futur proche. It works for everything from I'm going to grab a coffee to next year I'm moving to Berlin.
- In writing, news, formal speech, vows, and polite instructions, prefer futur simple.
- After si (if-clause): always présent. After quand, lorsque, dès que: always a future tense (futur simple is the cleanest pick).
- In the futur proche, object pronouns go before the infinitive, not before aller. Drill je vais le faire, je vais te dire.
- The traditional textbook line that futur proche = near and futur simple = distant is a useful first approximation, but register is the bigger driver of the choice in practice.

- Le Futur: OverviewA1 — French has two main futures — the synthetic futur simple (je parlerai) and the analytic futur proche (je vais parler) — plus the futur antérieur (j'aurai parlé) for completed future actions. This page maps how each is built, when each is used, and how they divide up the future-time space.
- Futur Proche: Going to / Immediate FutureA1 — The futur proche is built with aller in the present plus an infinitive — je vais manger, tu vas partir. It dominates spoken French for plans, intentions, and imminent events, and maps almost perfectly onto English 'going to' + verb.
- Futur Simple: Regular FormationA1 — Build the futur simple by adding the endings -ai, -as, -a, -ons, -ez, -ont to a stem that — for regular verbs — is the full infinitive (or the infinitive minus the final -e for -re verbs). Includes the spelling adjustments that affect -yer, -eler/-eter, and é/è verbs.
