The simple future tense, or future simple tense as it is also called, is used when you are making a promise,  predicting something will happen, or when referring to something that is habitual.

These are the ways simple future tense can be used. Let’s look more closely at usage of the simple future tense. It is used to make promises. For example:
I will do my homework.
There is a knock on the door. I will open it!
Promise you will go with me.

The simple future tense makes use of the phrase, ‘going to’, to talk about something that will happen in the future. This is used when we are predicting something based on current evidence:
The car is going to crash.  It is going too fast.

Simple future is used when you want to talk about a future (unplanned) action. For example:
Don’t worry! I will help you with this problem.
I will close the window. It’s starting to rain.

We often use the simple future when making a prediction based on experience or intuition:
It will not be easy.

The use of this tense to express habits is one of the common ways that this tense is used:
The dogs will always bark at 5 am.

Notice that the use of ‘shall’ in the simple future sentence has the same function as ‘will’, but it is a more formal word and is most often used in legal agreement, contracts, etc. And also in formal speeches, such as Winston Churchill’s famous line:
‘We shall fight them on the beaches, we shall never surrender!’

ABBREVIATIONS are often used for simple future tense:
Will  –    She’ll  be going to university next year.
Will not  –  She won’t be going to university until next year.

Final thought – do not use ‘will’ to say what somebody had already arranged to do in the future:
Mavis is starting dance classes next week. Correct
Mavis will start dance classes next week. Not correct
