I will go or I am going to go? What is the difference?

We can use both forms to express predictions in the future. The biggest difference is that be going to expresses a plan that the speaker made before the conversation. Will shows a decision that the speaker makes at the time of speaking.

Consider this situation:

Terry, would you like to come to my house for dinner tomorrow night? I am going to have a dinner party. I am not sure what dessert to have…. Oh I know, we will have chocolate ice cream sundaes!
