Use I'll to announce a decision made at the moment of speaking, and to offer, agree or promise. Use shall I ...? and shall we ...? to offer or to ask for a suggestion.
A I'll: a decision made now
Use I'll (I will) when you have just decided to do something. Saying I'll do it announces the decision as you make it.
Do not use the present simple (I do, I go) in these sentences.
I think I'll ... and I don't think I'll ... are very common.
In spoken English, will not is usually won't.
- Oh, the bins haven't gone out. I'll take them now.
- "What can I get you?" "I'll have a lemonade, please."
- "Did you book the table?" "Oh no, I completely forgot. I'll ring them now." (not I ring them now)
- I'm a bit peckish. I think I'll make some toast.
- I don't think I'll go to the match. It's freezing.
- You look busy, so I won't keep you. (I will not keep you)
B Offering, agreeing, promising, refusing
I'll is common when you offer, agree or promise to do something.
Use won't to say that somebody refuses to do something. Machines can refuse too, and frequently do.
Will you (do something)? asks somebody to do it.
- Those boxes look heavy. I'll carry one for you. (offering; not I carry)
- "Could you post this letter on your way?" "Of course. I'll drop it in the box by the chemist's." (agreeing)
- Thanks for covering my shift. I'll do yours next week. (promising)

- I've asked him to see a doctor, but he won't go.
- The printer won't print. (the printer refuses to print)
- Will you please stop tapping your pen? It's driving me up the wall.
C Not for things already arranged
Do not use will for something you decided or arranged before. Use the present continuous (see Unit 19).
- I'm going to Malta next week. (not I'll go)
- I'm seeing the bank manager on Tuesday. (decided before)
- "I'll see you outside the library at two, then?" "Perfect. See you there." (decided now)
D shall I ...? and shall we ...?
Today we use shall mostly in the questions shall I ...? and shall we ...?. Use them to ask whether it is all right to do something, or to ask for a suggestion.
Compare: Shall I turn the heating up? (do you want me to?) and Will you turn the heating up? (I want you to).
- Shall I put the kettle on? (do you want me to?)
- I've missed the last bus. What shall I do? (what do you suggest?)
- "Shall we head off?" "Give me two minutes. I can't find my scarf."
