Many English learners struggle with shall vs will because both words can refer to the future. Older grammar books often taught strict rules about when to use each one, but modern English works differently.
Today, will is far more common in everyday American English. Meanwhile, shall survives mostly in formal writing, legal language, suggestions, and certain traditional expressions.
For example:
- “I will call you tomorrow.”
- “Shall we start?”
Both sentences are correct, but they create different tones and purposes. Understanding the difference helps you sound more natural and avoid overly formal wording.
Quick Answer
Use will for most future situations in modern English.
Use shall mainly for:
- suggestions
- formal promises
- obligations
- legal or official writing
Examples:
- “We will arrive at noon.”
- “Shall we leave now?”
The two words sometimes overlap, but tone and context usually determine which one sounds natural.
Why People Confuse Them
People confuse shall and will because older grammar rules treated them differently from modern English.
Traditional grammar often taught this pattern:
- “I/we shall”
- “You/he/she/they will”
For strong determination, the rule supposedly reversed:
- “I/we will”
- “You/he/she/they shall”
Most native speakers no longer follow these rules consistently, especially in the United States.
Modern English usually prefers will in conversation:
- “I will see you later.”
- “We will call you tomorrow.”
At the same time, shall still appears in formal contexts:
- “Shall we begin?”
- “The tenant shall pay all fees.”
This mix of old rules and modern habits keeps the topic confusing.

Meaning and Usage Difference
Both shall and will are modal auxiliary verbs connected to future meaning.
Will
In modern English, will handles most future situations.
It commonly expresses:
- future actions
- predictions
- promises
- intentions
- willingness
Examples:
- “I will finish the report tonight.”
- “She will probably arrive early.”
- “We will help you move.”
This usage sounds neutral and natural in American English.
Shall
Modern English uses shall much less often.
It usually appears in:
- suggestions
- offers
- formal declarations
- legal obligations
Examples:
- “Shall I open the window?”
- “Shall we order pizza?”
- “You shall obey the rules.”
Legal writing especially favors shall because it can signal obligation or requirement.
Example:
- “The company shall provide written notice.”
Historical Rule
Older grammar traditions tried to separate shall and will by grammatical person. Modern speakers rarely follow those patterns consistently.
Today, most Americans simply use will for ordinary future meaning.
Tone, Context, and Formality
The biggest difference between shall and will is tone.
Will
Will sounds:
- neutral
- conversational
- modern
- natural in daily speech
Examples:
- “I will text you later.”
- “They will meet us downtown.”
Shall
Shall may sound:
- formal
- literary
- authoritative
- ceremonial
- old-fashioned in some contexts
Examples:
- “We shall overcome.”
- “The tenant shall pay all fees.”
In legal documents, shall often carries stronger authority than will.
Compare:
- “The employee will submit reports.”
- “The employee shall submit reports.”
The second sentence sounds more mandatory and official.
Still, not every use of shall sounds outdated. Questions like “Shall we begin?” remain common and natural.
Which One Should You Use?
For most modern English situations, use will.
Examples:
- “Will you join us?”
- “I will send the email tonight.”
- “They will arrive tomorrow.”
Use shall mainly when:
- making polite suggestions
- offering help
- writing formally
- reading legal or official language
Examples:
- “Shall we continue?”
- “Shall I carry that for you?”
- “The buyer shall pay all taxes.”
A practical rule:
- Everyday future → will
- Formal or suggestion-based tone → shall
Audience and context matter more than memorizing old grammar charts.
When One Choice Sounds Wrong
Sometimes the wrong choice creates an unnatural tone.
Example:
- “Shall you be there tonight?”
This sounds stiff or overly formal in modern American English.
More natural:
- “Will you be there tonight?”
Another example:
- “Will we begin?”
This sounds more like a prediction than a suggestion.
If the speaker wants to politely start an activity, this sounds better:
- “Shall we begin?”
The meaning changes because shall often signals suggestion or invitation in questions.
Common Mistakes (and Quick Fixes)

Overly formal:
- “I shall call you tomorrow.”
More natural:
- “I will call you tomorrow.”
Mistake: Using “will” for polite suggestion questions
Less natural:
