Shall vs Will

Shall vs Will: What’s the Difference in Modern English?

Many English learners are confused about shall vs will, especially because older grammar rules differ from modern usage.

However, language evolves. In modern English, we normally use will for all persons when talking about the simple future. Shall remains in the language, but we use it only in specific situations, mainly in questions, polite suggestions, formal instructions, and legal or official writing.

Let’s break it all down clearly.

When to Use Will

If you’ve ever felt unsure about which auxiliary verb to choose, this is the easy part:

Use will for all persons — singular and plural — when forming the future tense.

Examples:

• We will begin work in September.
• How long do you think this heat will last?
• The shops will open at eight o’clock tomorrow morning.

Contracted Forms

• will → ’ll
  • I think he’ll make an excellent pianist one day.
• will not → won’t
  • Don’t worry, Mum. We won’t go far.

These forms are extremely common in spoken English and informal writing. 

When to Use Shall

Although shall sounds more formal and is far less common in everyday English, we still use it naturally in a few situations:

Offers, Suggestions & Asking for Advice (First Person Only)

When speaking politely or making a suggestion, shall works beautifully:

• It’s so hot today! Shall I open the window?
• Shall we go now? I’m getting a bit tired.
• My car has broken down — what shall I do?

This use is especially common in British English.

Question Tags with “Let’s…”

When encouraging someone or suggesting an activity with let’s, the correct question tag is shall we?

• Let’s go for a swim, shall we?
• Let’s take a break, shall we?

Formal or Official Instructions

You will still see shall in rules, regulations, contracts, or official notices:

• Candidates shall submit their application forms at least one week before the exam.
• All employees shall wear identification badges while on the premises.

It sounds formal, authoritative, and very official.
