As a general rule, use 'will' for affirmative and negative sentences about the future. Use 'will' for requests too. If you want to make an offer or suggestion with I/we, use 'shall' in the question form. For very formal statements, especially to describe obligations, use 'shall'.
Where we use will?
We often use will (or the contracted form 'll) in the main clause of a conditional sentence when we talk about possible situations in the future: If she gets the job, she will have to move to Germany. I'll take a day off if the weather's fine next week.
When to use shall will and going to?
To summarise –
- Use shall for asking suggestions and with first person. ( I, we)
- Use will for future tense and to offer help or agree/disagree with something. Use will when you plan to do something which is not decided concretely.
- Use going to when a plan has been decided (in future)
