Shall and will can both refer to the future, but they are not equally common or interchangeable in every setting. Will is the ordinary future form for all subjects. Shall remains useful in formal first-person statements, offers and suggestions with I or we, and some legal or administrative drafting traditions.
When Should You Use Shall or Will for the Future?
Use will for ordinary future statements with any subject. Use shall with I or we when a deliberately formal future style is appropriate.
Will has the same structure with every subject and is the most common basic future form.[1]
- I will call after lunch.
- We will receive the results on Friday.
- You will find the key in the top drawer.
- The office will reopen in September.
For ordinary future-time reference, shall occurs with I and we and sounds more formal than will.[2]
- I shall return before sunset.
- We shall consider the proposal at the next meeting.
These sentences are grammatical, but “I will return” and “We will consider” are more neutral in current everyday English. Will is much more common for futurity, while shall can create a formal or old-fashioned tone.[3]
| Purpose | Common choice | Example |
|---|---|---|
| Neutral future statement | will | We will arrive at nine. |
| Negative future statement | will not / won’t | The shop won’t open tomorrow. |
| Formal first-person future | shall | I shall contact you in writing. |
| Offer with I | Shall I …? | Shall I carry that box? |
| Suggestion with we | Shall we …? | Shall we begin with the summary? |
| Request to another person | Will you …? | Will you close the window? |
Older prescriptive guidance assigned shall to first-person futurity and will to other subjects. Most speakers do not consistently follow that historical division, and modern usage often treats the forms as interchangeable in future statements.[4][3] That history explains examples in older writing, but it is not a reliable rule for editing ordinary current prose.
Negatives follow the same practical pattern. “I will not attend” is neutral. “I shall not attend” is possible but markedly formal.[2] In an ordinary notice, will not is the safer default. A document using formal first-person shall should keep that register deliberate and consistent instead of changing modals merely for variety.
Neither word provides a guaranteed measure of certainty. “I will finish today” can express a prediction, intention, promise, or determination depending on context. “I shall finish today” may sound formal or emphatic, but the modal alone does not prove that the event will happen.
How Do Shall and Will Work in Questions and Legal Writing?
Use Shall I …? and Shall we …? mainly for offers or suggestions; use will in ordinary future questions and requests. In legal drafting, follow the governing convention rather than assuming either word is automatically precise.
Questions with shall I and shall we usually offer an action or invite a joint decision instead of requesting a prediction.[2]
- “Shall I open the door?” offers to open it.
- “Shall I email the receipt?” asks whether the speaker should take that action.
- “Shall we postpone the meeting?” proposes a shared decision.
- “Shall we take the earlier train?” suggests a plan.
Questions with will can ask about an expected future event or make a request, particularly with you.[4]
- Future information: “When will the results appear?”
- Prediction: “Will the road be busy tonight?”
- Request: “Will you sign this copy?”
- Willingness: “Will you join us for dinner?”
“Will I open the window?” may occur when someone seeks confirmation, but “Shall I open the window?” is the clearer conventional offer. Conversely, “Shall you open the window?” is not the ordinary way to request action from another person; “Will you open it?” fits that purpose.
Legal uses require more caution than a simple substitution chart can provide. One legal-writing convention confines shall to a duty imposed on a capable actor and rejects it for mere future events, statuses, or supposed duties of inanimate objects.[5] Under that convention, “The tenant shall pay the fee” imposes a duty, while “The hearing shall occur in June” misuses the term for a future event.
A competing drafting approach uses will to create a contractual promise, not merely to predict the future.[5] The same legal-writing discussion notes disagreement: one approach recommends carefully drafted will, while another accepts shall when it is used consistently.[5] A separate usage source likewise observes that contracts use both terms for obligations and that their conventions can vary or become ambiguous.[3]
The practical conclusion is not that one modal guarantees legal precision. A drafter should follow the applicable jurisdiction, organization, contract template, and defined drafting convention. Identify the actor and the duty directly, and do not alternate shall and will merely for variety. This grammar comparison cannot determine the legal effect of a particular clause.
How Can You Choose Shall or Will in Context?
Choose from the sentence’s purpose: neutral future, formal first-person future, offer, suggestion, request, or a defined drafting convention. Do not rely on the subject alone.
Complete each item with shall or will. In two items, both are grammatical but one is the more neutral choice described in the key.
- Use neutral current prose: The library ___ reopen at ten tomorrow morning.
- ___ I carry the second suitcase for you?
- ___ we review the budget before discussing the schedule?
- ___ you send me the final file by noon?
- I ___ email the receipt this afternoon. Use neutral everyday style.
- We ___ remember those who served. Use a deliberately formal ceremonial tone.
- When ___ the next train arrive?
- The printer ___ not be available during maintenance. Use neutral current prose.
- ___ I turn off the lights, or are you still working?
- We ___ meet outside the theater at seven. Use neutral conversational style.
- ___ we invite the design team as well?
- Use neutral current prose, not a defined duty convention: The chair ___ announce the decision after the vote.

- will — This is an ordinary prediction about an inanimate subject.
- Shall — The speaker offers to carry the suitcase.
- Shall — The speaker proposes a shared sequence of actions.
- Will — The question requests an action from you.
- will — Both will and formal shall are possible with I, but will is neutral.
- shall — The prompt explicitly requests formal, ceremonial first-person style.
- will — The question asks for future information.
- will — Will not is the neutral future negative.
- Shall — The speaker offers to perform the action.
- will — Will is the ordinary conversational future form with we.
- Shall — The question invites a joint suggestion or decision.
- will — This is a neutral future statement about a third-person subject.
Now correct the modal choice or explain why no correction is needed:
- “Shall you send the invoice?” intended as a routine request.
- “We shall publish the minutes tomorrow” in a formal institutional notice.
- “Shall we take a break?”
- “I will call you tonight” in ordinary conversation.
Corrections
- Will you send the invoice? Will you is the ordinary request form addressed to another person.
- No correction is required. Shall is grammatical with we and suits the specified formal tone; will would be more neutral.
- No correction is required. Shall we introduces a suggestion.
- No correction is required. Will is the standard neutral future choice with I.
Context prevents false corrections. A form that sounds marked in conversation may be intentional in a ceremony, older text, institutional notice, or defined legal style. Name that context instead of treating every difference as a universal rule.
