English — future (will / going to)

English has no single future tense. It uses will and be going to — and even the present — depending on what you mean.

How it works

✓ Rule

will + base verb for predictions and instant decisions: I will help (I'll help). be going to + base verb for plans you already have: I'm going to travel. Negatives: won't / 'm not going to.

Good to know

⚠ Note

will and going to often overlap, and both are fine in many sentences. In future time clauses with when and ordinary open conditions with if, use the present rather than will: If it rains, we'll stay home (not “if it will rain”).
