Introduction
In English, there are two common ways to talk about the future: using “will” and “going to”. While both express future actions, they are not always interchangeable. Choosing the correct form depends on intention, plans, or predictions.
In this post, you’ll learn the difference between “will” and “going to” with clear grammar rules, examples, and practical usage tips.
Using “Will” in Future Tense
“Will” is often used when:
- Making decisions at the moment of speaking
- Making offers or promises
- Expressing predictions or beliefs about the future
Structure:
Subject + will + base verb
Examples:
- I will help you with your homework. (Offer)
- She will probably win the game. (Prediction)
- We will visit him tomorrow. (Decision made now)
Using “Going to” in Future Tense
“Going to” is used when:
- You have already decided or planned something
- There is evidence something is going to happen soon
Structure:
Subject + am/is/are + going to + base verb
Examples:
- I am going to start a blog next week. (Pre-decided plan)
- Look at the sky! It is going to rain. (Prediction with evidence)
Key Differences – Will vs Going to
| Situation | Use “Will” | Use “Going to” |
| Instant decision | I’ll call him now. | Not used |
| Pre-decided plan | Not preferred | I’m going to call him later. |
| Prediction (opinion-based) | It will snow tonight. | Not preferred |
| Prediction (with evidence) | Less common | Look at the clouds! It’s going to snow. |
| Promises / offers / threats | I will help you. | Not natural |
