"Shall" is a formal or archaic modal for first person, suggestions, and legal obligations; "will" is the general future for all persons in modern English.
Modal verb: (1) In modern English, mainly in questions to SUGGEST or PROPOSE: "Shall we go?" = should we go? / how about we go? (2) In formal and legal English: obligation or command. "The tenant shall pay rent on the first of each month" = the tenant is REQUIRED to pay (contractual language). (3) In old formal British English: simple future with I/We: "I shall return" = I will return. Today sounds archaic in everyday speech.
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.
Modal verb: general future for ALL persons (I, you, he, she, we, they) in modern English. "I will go" = I will go. "She will finish" = she will finish. "We will see" = we will see. Has nearly completely replaced "shall" for the simple future in American English and in everyday British English. Also expresses willingness, promises, and spontaneous decisions.

Common mistake
The most common error: not using "shall" for suggestions and proposals in formal English. "Do we go?" or "Should we go?" can work, but "Shall we go?" is the most elegant and precise form for proposing something. Second error: believing "shall" only exists in archaic texts — in modern legal and contractual English, "shall" is the standard form for expressing legal obligation, and confusing it with "will" in those contexts can change the legal meaning of the document.
Trick to remember it
WILL = simple future for everything (I, you, he, she, we, they). It is what you use 95% of the time. SHALL appears in 3 specific contexts: (1) "Shall we...?" / "Shall I...?" = proposal or suggestion (very useful in formal English). (2) Contracts and laws: "shall" = legal obligation. (3) Archaic literary English: "I shall return." For everyday use: WILL for everything. To make an elegant suggestion: "Shall we?" For contracts: SHALL = obligation.
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 19th-century British English, there was a very precise rule: "shall" with I/we = simple future. "Will" with I/we = emphasis or strong will. "I shall drown, nobody will save me!" = I will drown, nobody will save me (no intention). "I will drown, nobody shall save me!" = I will drown (by my own will), nobody shall save me (I forbid it). This distinction was so subtle that 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.
