'Shall' is a formal modal for first person or legal contexts; 'will' is the general future for all persons in modern English.
Side-by-side comparison
Shall
verbo modal"Will" is the standard form for talking about the future in all contexts and persons. It is the one used in everyday English everywhere.
Shall we take a break? We have been working for three hours straight.
The contract states that the contractor shall complete all work before the agreed deadline.
Shall I open the window? It is getting warm in here.
Will
verbo modal"Shall" is mainly used in British English with "I" and "we" for the future, and in questions to make suggestions or offer help: "Shall we go?"

Common mistake
- •The most common error: not knowing that "shall" is used in formal English for suggestions ("Shall we go?").
- •The second: confusing them in contracts, where "shall" expresses legal obligation and is not interchangeable with "will."
Trick to remember it
When do you use SHALL in modern English? Only 2 cases: "Shall we...?" (formal suggestion), and legal contracts ("Payment shall be due..."). Outside those 2, WILL — always, no exception.
Quick rule
- •"Will" = general future for all persons (everyday use).
- •"Shall" = formal suggestions ("Shall we?"), legal obligations in contracts, and archaic English with I/we.
Did you know?
In classic nineteenth-century British English, there was a very precise rule: SHALL with I/we expressed neutral simple future; WILL with I/we expressed strong will or determination. "I shall drown, nobody will save me!" meant "I will drown, nobody will save me" (no intention involved). "I will drown, nobody shall save me!" meant "I intend to drown, and I forbid anyone to save me." This distinction was so subtle that George Bernard Shaw satirized it: he said only the English understood the difference, and even among themselves there was disagreement. Today the distinction has nearly disappeared from American English, surviving only in formal British English and legal language.
