What is the Future with Will?
The future with will uses the modal auxiliary will followed by the base verb — no conjugation, no agreement changes. It is the same for every subject: I will, you will, he will, she will, we will, they will.
Will is not the only way to talk about the future in English — going to, the Present Continuous, and even the Present Simple all do this too. Will is the right choice when you are making a decision in the moment, expressing a general prediction or belief, making a promise or offer, or stating a future fact or certainty. If the decision was made before you started speaking, use going to instead.
One critical rule learners often miss: will is never used in conditional or time clauses. After if, when, as soon as, until, before, after, English uses the Present Simple to refer to the future — not will. This is one of the most tested points at B1 level.
Will also has a hidden second life: it is used in the present, not the future, to talk about refusal. The form "won't + base verb" can mean "refuses to". "The door won't open" does not mean the door has some future plan — it means the door is refusing to open right now. "He won't listen" means he is currently refusing to listen, not predicting a future refusal. This use is high-frequency in everyday English and rarely taught in textbooks.
Finally, will is the most register-flexible of all the future forms. It works in casual speech ("I'll grab a coffee"), in business writing ("The committee will review your proposal next week"), and in formal announcements ("The president will address the nation at eight o'clock"). Going to and the present continuous can sound too informal in a press release or contract; will fits every register from kitchen-table to courtroom.
How to Form It
Will never changes — no -s, no agreement. The verb that follows is always the base form (infinitive without to). In spoken English, will almost always contracts to 'll: "I'll call you", "She'll be there", "They'll understand."
Subject + will + base verbPositive
| Subject | will / 'll | Base verb | Example |
|---|---|---|---|
| I | will / 'll | call | I 'll call you tonight. |
| He / She / It | will / 'll | be | She 'll be here by 9. |
| You / We / They | will / 'll | understand | They 'll understand eventually. |
Negative and Question
Subject + won't + base verb | Will + subject + base verb? — Short answers: "Will you come?" → "Yes, I will." / "No, I won't." Never "Yes, I will come" in a short answer — the base verb is dropped.
| Form | Structure | Example |
|---|---|---|
| Negative | won't + base verb | I won't tell anyone, I promise. |
| Negative (full) | will not + base verb | She will not accept that offer. |
| Question | Will + subject + base verb? | Will you help me with this? |
When to Use the Future with Will
Spontaneous decisions made at the moment of speaking
The most important use at B1 level: when you make a decision at the exact moment you are speaking — in response to a situation, a request, or something you have just heard or seen — use will. The decision was not made before this conversation. This is the key distinction from going to, which is for pre-planned decisions.
- "The phone is ringing." "I 'll get it."
- "We're out of milk." "Don't worry, I 'll buy some on the way home."
- "Can anyone help me move this table?" "I 'll do it."
- "I'm cold." "I 'll close the window."
- Looking at the menu for the first time: "I 'll have the steak, please."
Predictions based on opinion or belief
When you express what you think, believe, expect, or imagine will happen in the future — without specific visible evidence right now — use will. These are general opinions about the future, often introduced by I think, I expect, I'm sure, probably, definitely. Compare this with going to, which is used when you can see concrete evidence.
- I think it will rain tomorrow.
- She 'll probably get the job — she's very qualified.
- I'm sure you 'll love the film.
- In fifty years, people will live on Mars.
- He won't remember to bring the report — he never does.
Promises, offers, threats, and requests
Will is the standard form for interpersonal commitments — positive and negative. When you volunteer to do something (offer), commit to doing it (promise), warn someone of consequences (threat), or ask someone to do something (request), will is the natural form. These uses are all grounded in the present moment, which is why going to (pre-planned) sounds wrong here.
- Promise: I 'll always be there for you.
- Promise (negative): I won't tell anyone about this.
- Offer: I'll carry those bags for you.
- Offer: I'll give you a lift to the airport.
- Threat: If you do that again, I 'll call the manager.
- Request: Will you help me with this form?
Future facts and certainties
For events that are certain or inevitable in the future — fixed facts, scheduled natural events, or things that follow inevitably — will is the natural form. These are not personal plans or opinions; they are statements of fact about what is going to happen.
- The sun will rise at 6:12 tomorrow morning.
- She 'll be 30 next year.
- The conference will take place in Berlin this autumn.
- Water will freeze at 0°C.
Refusal in the present — won't + base verb
When something or someone refuses to cooperate right now, use won't (will not) + base verb. This is a present-tense meaning even though will is grammatically a future form. It works equally well with people, animals, and inanimate objects.
- The door won't open. (it is stuck right now)
- He won't listen to anyone. (he is refusing to listen)
- My phone won't connect to the Wi-Fi. (it is not connecting)
- She won't tell me what happened.
Formal announcements, press releases, and official statements
In formal contexts — government statements, business communications, news anchors, legal documents — will is the standard future form. Going to often sounds too conversational; the present continuous can sound presumptuous. Will is the safe, neutral, formal choice.
- The CEO will announce the merger at the press conference tomorrow.
- The new policy will take effect on the first of January.
- Trains will not be running on Sunday due to engineering works.
- The defendant will appear in court next Monday.
Warnings, advice, and natural consequences
Use will to warn someone about a likely consequence of their actions or to give advice about what is bound to happen. The structure often pairs with an if-clause or a time clause that names the trigger.
- If you eat too much, you 'll feel sick.
- You 'll regret it if you don't apologise.
- Hurry up, or we 'll miss the train.
- You 'll love this restaurant — it's perfect for you.
Strong commands and insistence — you will
When a speaker in authority issues an order or insists on compliance, will (often stressed) can replace must or have to. The tone is firm, sometimes severe — appropriate for parents, officers, or bosses to subordinates. Use carefully: this is the most assertive use of will.
- You will do as I say and that's final.
- You will apologise to your sister right now.
- All staff will report to the conference room at nine sharp.
Time Expressions
Will vs Going To
This is the most important distinction at B1. Both forms can talk about the future, but they answer different questions about the speaker's relationship to the future event. Getting this right is one of the clearest markers of B1 fluency.
Will — spontaneous decision (now)
"I will have the soup." (decides at the table)
The decision is made this second, in response to seeing the menu. No prior planning.
Going to — pre-made decision (before)
"I am going to have the soup." (decided before sitting down)
The decision was already made — the speaker came in planning to have soup.
Will — general opinion or belief
"I think it will rain tomorrow."
A personal belief about the future — no specific visible evidence, just an opinion.
Going to — evidence visible right now
"Look at those clouds — it is going to rain."
The speaker can see the clouds now. The prediction is grounded in present observation.
Will in Conditionals and Time Clauses
One of the most important rules about will: it cannot be used in the conditional or time clause — only in the main clause. In the subordinate clause introduced by if, when, as soon as, before, after, until, by the time, English always uses the Present Simple to refer to the future.
Correct — Present Simple in the if/when clause
If it rains, we will stay inside.
The if clause uses Present Simple (rains), even though it refers to the future.
Wrong — will in the if/when clause
If it will rain, we will stay inside. ✗
Using will in an if clause is ungrammatical in standard English.
Correct — Present Simple in the when clause
When she arrives, I will tell her the news.
The when clause uses Present Simple (arrives). Will goes in the main clause only.
Wrong — will in the when clause
When she will arrive, I will tell her the news. ✗
Using will in a when time clause is a very common learner error.
The rule in one sentence: In sentences with if, when, as soon as, before, after, until, by the time — use Present Simple in the subordinate clause and will in the main clause — never will in both.
Exception worth noting: "if" sometimes does take will when it means "whether" ("I don't know if it will rain") or when expressing a polite request ("If you will sign here, please…"). These are not first-conditionals — they are different uses of "if". When if introduces a real future condition, the present-simple rule still applies.
Will vs Shall (British English)
Shall is a dying form in modern English, but it still survives in two specific contexts. Knowing when to use it sounds polished in British English exam writing and feels appropriately formal in legal documents. American English avoids shall almost entirely except in legal contexts.
Shall — first-person offers and suggestions (BrE)
Shall I open the window? / Shall we go now?
Polite first-person suggestion or offer in British English. Native speakers under 40 increasingly use should instead ("Should I open the window?"). Still standard in formal writing.
Will — every other future use
Will I see you tomorrow? / Will we still be here at 9?
Future questions about predictions, plans, or facts use will, not shall. The shall variant would sound archaic or comic in those contexts.
Shall — legal and contractual obligation
The tenant shall pay the rent by the first of each month.
Legal English uses shall to express mandatory obligation. In a contract, "shall" means "must" — not a future prediction.
Will — neutral future fact
The tenant will pay the rent by the first of each month.
Outside legal writing, this version is more natural. In contracts and statutes, the shall version remains the convention, though plain-English advocates argue for must.
For day-to-day learners: it is safe to use will everywhere shall might appear, except in two specific spots — "Shall I…?" and "Shall we…?" for offers and suggestions in British speech. American English doesn't even require those exceptions.
Common Mistakes
Using "will" in the if/when clause of a conditional
✗ If it will be warm tomorrow, we will go to the beach.
✓ If it is warm tomorrow, we will go to the beach.
After if (and all other time conjunctions: when, as soon as, before, after, until, by the time), the future is expressed with the Present Simple — never with will. This rule applies even when the situation is clearly future. The will belongs only in the main (result) clause.
Using "will" for a pre-planned decision (should be "going to")
✗ "What are you doing this weekend?" "I will visit my parents — I arranged it last week."
✓ "I am going to visit my parents." / "I am visiting my parents."
If the decision or arrangement was made before this conversation, use going to (intention) or the Present Continuous (confirmed arrangement). Will sounds as though you are deciding right now — which contradicts "I arranged it last week."
Adding "to" after "will"
✗ She will to call you later. / I will to go to the shops.
✓ She will call you later. / I will go to the shops.
Will is a modal auxiliary — it is followed directly by the base verb, with no to in between. "Will to go" confuses will with the going to structure. Always: will + base verb, no infinitive marker.
Using "going to" for spontaneous offers and reactions
✗ "You look tired." "I'm going to make you a cup of tea."
"I'll make you a cup of tea."
When you make a spontaneous offer in response to what someone has just said, will is the natural form. "I'm going to make…" implies you had already planned to make tea before noticing the person was tired — which sounds odd. Will matches the immediate, responsive nature of the offer.
Using "will" for evidence-based predictions
✗ Look at him — he will faint! (He's clearly about to faint.)
✓ Look at him — he is going to faint!
When the prediction is based on what you can see happening right now — someone swaying, looking pale — the correct form is going to. The phrase "Look at…" is a strong signal that you need going to, not will. Will is for opinions and beliefs, not for reporting what is visibly about to happen.
Using "will" for present habits or routines
✗ I will go to the gym every Monday. (talking about a regular habit)
✓ I go to the gym every Monday.
Routines and habits that are already established use the Present Simple, not will. Will would imply you are deciding right now to start going every Monday. Reserve will for genuine future actions or general predictions, not for facts about your current schedule.
"He said he will come" — wrong tense in reported speech
✗ She said she will be late. / He told me he will call.
✓ She said she would be late. / He told me he would call.
When reported speech is introduced by a past-tense verb (said, told, asked), will shifts back to would. This is one of the most common B1 reported-speech errors. The rule applies even if the reported event is still in the future at the moment of reporting — formal English consistently uses the back-shifted form.
Confusing "won't" refusal with future negative
✗ Reading "The car won't start" as a future prediction.
✓ "The car won't start" = "The car refuses to start (right now)."
When won't appears with an inanimate object or in the context of a present-moment problem, it signals refusal, not future negation. "The lid won't come off" means it is stuck right now, not that it will never come off. This use is high-frequency in everyday English.
Using "will" for personal arrangements between people
✗ "What are you doing on Saturday?" "I will meet my friends for dinner."
✓ "I am meeting my friends for dinner."
When the future plan is a confirmed arrangement between two or more people (a diary entry, an agreed meeting), use the present continuous. Will sounds as though you are deciding the answer in the moment of being asked — which contradicts the idea of an existing arrangement.
