"Need" is a real necessity; "want" is a personal desire.
To require something that is essential or necessary. Implies there is a problem without it.
I need to sleep. I have been awake for 24 hours.
Plants need water and sunlight to survive.
You need a passport to travel abroad.
To desire something you would like to have or do, even if it is not essential.
I want a new phone, but mine still works fine.
She wants to travel to Japan someday.
Do you want some coffee? I just made a fresh pot.
Common mistake
Using "want" when the situation requires "need": "I want a doctor" sounds like a whim instead of a medical emergency — the correct form is "I need a doctor". Another common error: "I am needing" — need is almost never used in continuous form in English (it is a stative verb). The correct form is "I need" without -ing.
Trick to remember it
Ask yourself: if I do not get it, are there real negative consequences? If yes, use "need". If it would just be nice to have, use "want". Empathy trick: "I need your help" (something bad will happen without it) vs "I want your help" (I would like your support, but could manage alone).
Quick rule
Need = real necessity (consequences if unmet). Want = personal desire (not required).
Did you know?
In psychology, the distinction between needs and wants is central to "Maslow's hierarchy": physiological and safety needs come before desires for achievement or status. In sales, the best salespeople convert "wants" into "needs" (perceived necessities) — that is exactly what marketing does.
