Simple future tense: Definition, usage, rules, examples and exercises

The future present tense is commonly used in English to talk about future predictions, promises, offers, and other situations. In this guide, you’ll learn the future simple tense definition, along with formulas, worksheets and detailed examples to help you use it with confidence. 

What is simple future tense?

The future simple tense is used to show an action, an event, or a state that will happen after the present moment. 

Simple future tense examples: 

• I will call you soon.
• It will rain tomorrow.

When to use future simple tense English? 

The future simple tense English can be used for various situations: 

• To predict a future event. Use “will” when you want to predict something in the future based on your opinion, belief, or expectation rather than concrete evidence.
  • For example: I think the opponent team will win the game.
• To express a spontaneous decision. By using “will” with “I’ or “we”, you can make a decision in the moment of speaking rather than planning it beforehand.
  • For example: Someone’s at the door. I’ll get it.
• To express willingness (or unwillingness, refusal in negative form).
  • For example: I’ll help you with the project.
• To express willingness, an offer, or instructions. In modern English, the modal verb “shall” is less common than “will”. However, it is still used with “I” to make an offer or ask what to do.
  • For example: Shall I clean up your table, sir?
• To make a suggestion. Use “Shall we...?” to make a suggestion or ask whether someone would like to do something.
  • For example: Shall we dance?
• To give orders. With the subject “you”, it can be used to give strong instructions or orders. However, this structure can sound firm or authoritative, so it’s best to use in situations where the speaker has the authority or wants to emphasize the situation.
  • For example: You will clean up your room before 5 p.m.
• To give an invitation. By beginning a question with “Will you..?”, you can invite someone to do something.
  • For example: Will you marry me?

Common mistake: Using "will" in time clauses

One common mistake when talking about the future is using will after time expressions such as when, after, before, as soon as, once, and until. When these words introduce a clause referring to a future time, use the simple present in that time clause rather than will. The main clause can still use will.

Formula: 

For example: When I get home, I’ll call you.

Not: When I will get home, I’ll call you.
