A good need synonym turns on the sense you intend (must have, are missing, or simply wish for): require, depend on, call for, lack and necessity handle most cases. Need is one of the most repeated words in emails and reports, so a few swaps go a long way.
This page covers the verb and the noun, the forms needs and needed, the grammar traps that catch learners, and the words that mean the opposite. For close relatives, compare require, want and demand.

Casual to formal: each need synonym on the strip
Scan the strip above: it moves from relaxed speech toward office prose. Have to have and could use belong in chat: I could use a coffee. Depend on sits in the middle and works almost anywhere. Require is the safe choice for instructions, forms and reports. Necessitate is stiff and usually takes a thing as its subject: the delay necessitated a new plan.
Pick by audience. A manual says the device requires charging, a friend says it needs charging.

Grammar traps when you replace need
Need can be followed by a noun or by to plus a verb. Its synonyms are pickier.
- Require takes a noun or an object plus to: staff are required to wear badges. Avoid it requires to wear.
- Lack takes no preposition as a verb: the room lacks light, not lacks of light.
- Call for needs a thing as subject: the situation calls for calm. People do not call for patience in this sense.
- Must has no past tense, so needed to becomes had to.
Need not and needn't are polite ways to say there is no need: you needn't bring anything. They sound a little British in casual speech.
Picking a word for work, study and everyday talk
In a cover letter, describe what a role requires and show how you meet it. In reports, depend on and rely on make links clearer than need. Teachers often circle need in essays when a stronger verb is available, so try demands or calls for. Messages to friends can stay simple: need is fine, and could use sounds friendly.
If you want help with a request, the ask synonyms and request synonyms pages give polite ways to phrase it. More office words sit in the action verbs hub.
Opposites of need
To show that something is not necessary, use do without, forgo or spare. To show you already have it, use have or possess. For the noun, surplus and excess describe having more than enough.
- We can do without the extra cables.
- The farm had a surplus of apples this autumn.
