Shall is about one fourth as common relative to will in North America as in the UK. Some in North America may consider it formal or even pompous.
In the past, will and shall have been used similarly as auxiliary verbs for the future tense. The simple future tense traditionally uses shall for the first person ("I" and "we"), and will for the second and third persons.
I shall go.
You will go.
An emphatic future tense, indicating volition of the speaker, reverses the two words, using will for the first person and shall for the second and third person.
I will go.
You shall go.
Usage can be reversed in questions and in dependent clauses—especially with indirect discourse. For example: Shall you do it? anticipates the response I shall do it. Or: he says that he shall win or he expects that he shall win anticipate his saying I shall win, not I will win.
