Simple Future Tense (Future Indefinite): Structure, Uses and 50 Examples

Jump to the formula, the short forms ’ll and won’t, the uses, will vs going to, shall, common mistakes, the 50 examples, the exercise or the other future tenses.

What is the simple future tense?

The simple future tense is the form will + base verb for an action or state after the moment of speaking: The results will come out on Friday. It has three names, simple future, future simple and future indefinite (EnglishPage lists all three), and Indian exam notes such as EduRev’s CBSE Class 10 page say “simple future indefinite tense”. The grammar is the same.

Unlike the past tense, the simple future has no verb ending of its own. Cambridge’s English Grammar Today states that “there is no future tense in English”: will is a modal verb, like can or must, and it is always followed by the base form of the main verb, whatever the subject.

Simple future tense formula and structure

The formula is subject + will + base verb. Negatives add not after will; questions put will before the subject. Cambridge’s will page adds that do, does and did are never used with will, so Does it will rain? is wrong.

In conversation, ’ll is not used in short answers (Yes, they will, not Yes, they’ll), and in writing it normally follows pronouns, not nouns (Jan’s father will fetch you). Cambridge keeps the full will not for formal contexts and for emphasis: I will not sign this.

How do you pronounce ’ll and won’t?

In speech, will usually becomes ’ll after a pronoun; Cambridge notes that ’ll is much more common in speaking than will or shall. On its own, ’ll is /əl/, and I’ll is one syllable, /aɪl/, the same sound as aisle.

EF’s grammar reference notes that “the form ‘it will’ is not normally shortened”, so write it will in formal text; you will still hear it’ll in fast speech.

When do we use the simple future tense?

Use the simple future for what you believe, decide, offer or promise. Cambridge’s will page and the British Council’s Talking about the future list these uses:

Two more details from Cambridge: after I think people usually say ’ll, not will (I think I’ll have some orange juice), and will can give orders or insist (You will wear it whether you like it or not).

To show how sure you are, put probably or definitely after will but before won’t, as the British Council’s degrees of certainty lesson does: We’ll probably finish the project by tomorrow, He probably won’t have enough time.

Will, going to or present continuous: which one should you use?

Use will for a decision you make now, be going to for a plan made before speaking or a prediction from what you can see, and the present continuous for an arrangement with a time. Cambridge’s pages on be going to, the present continuous and the present simple for the future draw the same lines as the British Council.

Quiz questions test exactly this line. Asked which sentence describes a pre-planned action, pick the going to one: “The Chennai team is going to launch the campaign next Monday” was decided before anyone spoke, while “I think we will see more customers next quarter” is only an opinion.

In casual speech, going to often sounds like gonna (UK /ˈɡə.nə/, US /ˈɡɑː.nə/). Cambridge calls gonna informal, used especially in speaking and song lyrics, so write going to.

Shall or will: is shall still correct?

Shall is correct but narrow. Cambridge’s dictionary labels future shall “old-fashioned” and suggestion shall “formal in US”, and its grammar page calls shall much less common than will. It still sounds natural in offers (Shall I open the window?), suggestions (Shall we go home?), asking for advice (What shall we do with this?) and formal rules (This door shall be kept closed at all times).

Some Indian exam notes still teach I/We + shall + verb as the first-person rule; follow your exam there. In speech and everyday writing, I will and I’ll are normal, and Cambridge rules out shall with other subjects in predictions: The new business cards will be ready, not shall be ready.

Time expressions used with the simple future

Time expressions tell the listener when: later, tonight, tomorrow, next week, next year, soon, one day, in ten minutes, in two days, at 6 p.m., on Monday, in 2030 and, for deadlines, by Friday: I’ll finish the report by Friday. The English prepositions guide explains when to use at, on and in.

Common simple future tense mistakes

The first five mistakes below break the pattern will + base verb; the other four use the wrong form for the situation. Cambridge’s grammar pages (including word patterns and typical errors) and the British Council flag these:

One exception: will can follow if when it means “are willing to”, as in the British Council’s I will be very happy if you will come to my party.

Simple future tense from Hindi to English

Hindi marks the future with a verb suffix, -gā, -ge or -gī (Hindustani grammar), which changes with gender and number. English adds will and leaves the verb alone:

How to talk about your future plans in English

To write or talk about your future plans, mix the forms: be going to for what you have decided, the present continuous for arrangements with a date, and will for predictions and promises (I think I’ll…, I’ll probably…). The passage below uses all three.

Read it once slowly, then again with the short forms. The shadowing method suits a passage like this, and the graded speaking practice texts give you longer ones. In the dialogue below, take Dawit’s lines.

For more practice, open the conversation question generator and answer any question with one plan (going to) and one prediction (will).

Simple future vs future continuous, perfect and perfect continuous

“Future tense” is the umbrella name; the simple future is one of the four future tenses that school grammars such as Vedantu’s list, all built on will. Cambridge has a page for each: the future continuous, the future perfect and the future perfect continuous.

The simple future names the action; the continuous puts you in the middle of it at a future time; the perfect looks back at something finished; the perfect continuous adds how long. To check which of these forms you already use correctly, try the free English level test in your browser.
