The Future Simple is your go-to tense for anything happening after "right now." It’s one of the easiest tenses in English because it doesn't change based on the subject (I, you, he, they—it’s all the same).
1. How to Form It
The formula is straightforward: Subject + Will + Base Verb.

Sentence Type	Structure	Example
Positive	Subject + will + verb	I will call you later.
Negative	Subject + will not (won't) + verb	She won't eat meat.
Question	Will + subject + verb?	Will it rain tomorrow?

Pro-Tip: In casual conversation, we almost always use contractions: I’ll, you’ll, he’ll, she’ll, it’ll, we’ll, they’ll.
2. When to Use It
While "going to" is often used for pre-set plans, will is used for:
Instant Decisions: You’re at a restaurant and say, "I will have the pasta."
Predictions: Based on your gut feeling rather than evidence. "I think the Lakers will win."
Promises & Offers: "I will help you with those bags."
Facts: "The sun will rise at 6:00 AM."
3. The "Shall" Exception
You might see shall in older books or formal legal documents. In modern English, we really only use it for making polite suggestions or offers in question form:
“Shall we dance?”
“Shall I open the window?”
4. Common Time Expressions
To make your sentences clearer, pair the Future Simple with these markers:
Tomorrow / Tomorrow morning
Next week / month / year
In five minutes / two days
Soon / Later
