Altogether vs All Together: Correct Meaning and Examples

Altogether and all together are both correct, but they do not mean the same thing. The space changes the meaning.

Use altogether when you mean “completely,” “in total,” or “on the whole.” Use all together when you mean “everyone or everything together,” “in one group,” “in one place,” or “at the same time.”

Quick Answer

Altogether is one word and usually means completely, in total, or overall. All together is two words and means as a group, in one place, or at the same time. Write “The trip cost $500 altogether,” but “The kids sat all together.”

Why People Confuse Them

People confuse these forms because they look almost the same and sound the same in normal speech. The only visible difference is the space.

That small space matters. Altogether works as a single adverb. All together is a two-word phrase made from all and together.

A helpful test is to replace the words.

If you can replace the term with completely, entirely, in total, or overall, use altogether.

If you can replace it with together, as a group, or in one place, use all together.

Key Differences At A Glance

Context	Best Choice	Why
Meaning “completely”	altogether	It modifies the whole idea or action.
Meaning “in total”	altogether	It gives the full amount or sum.
Meaning “on the whole”	altogether	It introduces an overall judgment.
People in one group	all together	It describes people being together.
Objects in one place	all together	It describes things gathered together.

Meaning and Usage Difference

Altogether is a one-word adverb. It can mean completely.

Example:
The office stopped using paper forms altogether.

Here, altogether means the office completely stopped using them.

It can also mean in total.

Example:
The repairs cost $850 altogether.

Here, altogether means the full amount was $850.

It can also mean on the whole or when everything is considered.

Example:
Altogether, the meeting was useful.

Here, the speaker gives an overall judgment.

All together is a two-word phrase. It means people or things are together as a group, in one place, or at the same time.

Example:
The guests arrived all together.

This means the guests arrived as one group or at the same time.

Example:
Put the receipts all together in one folder.

This means the receipts should be gathered in one place.

Both forms are pronounced the same in everyday speech: all-tuh-GEH-thur. Because they sound alike, the written space is what shows the difference.

Tone, Context, and Formality

Both forms are standard in American English. Neither is slang. The difference is not about formal versus informal style. It is about meaning and sentence structure.

Altogether can sound slightly more polished when it means on the whole.

Example:
Altogether, the proposal is strong.

This works well in school, business, and everyday writing.

All together sounds natural when you are talking about people, items, or actions being grouped.

Example:
Let’s take the photo all together.

This fits casual speech, family plans, classroom directions, and workplace instructions.

The key point is simple: choose the form that matches the idea, not the tone.

Which One Should You Use?

Use altogether when you mean:

• completely
• entirely
• in total
• overall
• all things considered

Examples:
The app crashed and stopped working altogether.
We spent $120 altogether.
Altogether, it was a good weekend.

Use all together when you mean:

• together as a group
• in one place
• at the same time
• with each other

Examples:
The team waited all together in the lobby.
Keep the documents all together.
The class read the final line all together.

Here is a compact comparison:

Feature	Altogether	All Together
Form	One word	Two words
Main role	Adverb	Phrase
Core meaning	Completely, in total, overall	In a group, in one place, at the same time
Best test	Replace with “completely” or “in total”	Replace with “together”
Example	The plan failed altogether.	We worked all together.

When One Choice Sounds Wrong

Some sentences sound wrong because the meaning points clearly to only one form.

Wrong:
The team stood altogether near the entrance.

Correct:
The team stood all together near the entrance.

The team was standing in one group, so the two-word phrase is correct.

Wrong:
The plan was all together unrealistic.

Correct:
The plan was altogether unrealistic.

The meaning is “completely unrealistic,” so the one-word adverb is correct.

Wrong:
We paid $300 all together.

Correct:
We paid $300 altogether.

The sentence gives the full amount, so altogether is the better choice.

However, context can change the answer.

Example:
We sang all together.

This means everyone sang as one group.

Example:
We stopped singing altogether.

This means we completely stopped singing.

Common Mistakes (and Quick Fixes)

Mistake 1: Using all together for “completely”

Incorrect:
The idea was all together different.

Correct:
The idea was altogether different.

Quick fix: If you mean completely, use one word.

Mistake 2: Using altogether for a group

Incorrect:
The students sat altogether at lunch.

Correct:
The students sat all together at lunch.

Quick fix: If you mean people are in a group, use two words.

Mistake 3: Using the wrong form with totals

Incorrect:
The tickets cost $75 all together.

Correct:
The tickets cost $75 altogether.

Quick fix: If you mean in total, use altogether.

Mistake 4: Missing the split phrase pattern

Correct:
We were all together by 8 p.m.

Correct:
Put all the files together before the meeting.

In the second sentence, all and together are separated by the files. That is a strong clue that the phrase, not the one-word adverb, is being used.
