Will and going to are verb forms we use with predictions. They are grammatically a part of the future tense. There are some small but important differences between will vs going to.

Will vs Going To Explanation

Will we use with rapid decisions, something decided at the moment, or an offer, promise, and threat even. Will is the form for something that just comes to mind, and we decide to do it.


  • I will get a cheeseburger. 
  • Thanks for the lovely dinner, I will clean up at least.
  • This concert is not for me. I think I will go to my friend’s party instead. 

Going to we use when describing some longer plan, something ongoing, and some kind of evidence or sign. Going to is a form to use when more thought has been put into an action.


  • We talked about it for ages, and we are going to Argentina for our honeymoon.
  • We are going to offer you an extended contract after this trial period is over.
  • I heard he is going to quit in May. He’s been talking about it for a long time now. 

Will and going have these slight differences. Will is a much quicker decision, and going to is more throughout plan. Both are equally important for the proper use of future tenses.
