Going to or will

When we want to talk about future facts or things we believe to be true about the future, we use 'will'.

• The President will serve for four years.
• The boss won't be very happy.
• I'm sure you'll like her.
• I'm certain he'll do a good job.

If we are not so certain about the future, we use 'will' with expressions such as 'probably', 'possibly', 'I think', 'I hope'.

• I hope you'll visit me in my home one day.
• She'll probably be a great success.
• I'll possibly come but I may not get back in time.
• I think we'll get on well.

If you are making a future prediction based on evidence in the present situation, use 'going to'.

• Look at the queue. We're not going to get in for hours.
• The traffic is terrible. We're going to miss our flight.
• Be careful! You're going to spill your coffee.

At the moment of making a decision, use 'will'. Once you have made the decision, talk about it using 'going to'.

• I'll come and have a drink with you but I must let Harry know. Harry, I'm going to have a drink with Simon.
