The choice between “it worth it” and “it is worth it” looks small, but one missing word changes the grammar of the sentence.
In standard American English, “it is worth it” is the correct complete expression. “It worth it” is not a complete standard-English sentence because it has no linking verb.
The confusion often comes from treating worth as though it were an ordinary verb. In this construction, it is not.
Quick Answer
“It is worth it” is correct.
“It worth it” is incorrect in standard English.
The structure is:
It + is + worth it.
Here, it is the subject, is is the linking verb, and worth it describes the value of something compared with its cost, time, effort, difficulty, or other sacrifice.
For example:
- It is worth it. ✅
- It was worth it. ✅
- It will be worth it. ✅
- It worth it. ❌
In everyday conversation, “It’s worth it” is also completely natural. It is simply the contraction of “it is worth it.”
Why People Confuse Them
The main problem is that worth looks as though it could function as the main verb.
Compare:
It works.
Here, works is the verb.
But:
It is worth it.
Here, is is the verb. Worth describes value.
That difference matters when you form questions and change the tense.
You say:
Is it worth it?
not:
Does it worth it?
You also say:
It was worth it.
not:
It worth it yesterday.
The small word is does important grammatical work. Removing it leaves the sentence without the verb it needs.
Key Differences At A Glance
- It worth it: incomplete and incorrect as a standard sentence.
- It is worth it: complete and grammatically correct.
- Worth: describes value or usefulness in this construction.
- Is: carries the present-tense verb function.
- It’s worth it: a natural contraction of the correct full form.
The important difference is therefore grammar, not meaning. The two expressions are intended to communicate the same basic idea, but only one forms a standard complete sentence.
Meaning and Usage Difference
It is worth it means that something provides enough value or benefit to justify what you have spent or experienced.
That cost does not have to be money. It can be time, effort, inconvenience, risk, discomfort, or another sacrifice.
For example:
The concert tickets were expensive, but it was worth it.
The speaker means that the experience justified the expense.
The same idea works with effort:
Training every morning is difficult, but it is worth it.
Here, the benefit of training justifies the effort.
The construction can also use a specific noun or an -ing form:
The upgrade is worth the money.
The book is worth reading.
The trip is worth taking.
This is why worth should not be treated like an ordinary action verb.
Tone, Context, and Formality
It is worth it works in both everyday and formal English.
The full form can sound slightly more deliberate, especially when a writer wants to emphasize the statement:
The additional expense is significant, but it is worth it.
In normal conversation, Americans commonly use the contraction:
It’s worth it.
The contraction does not change the basic meaning. It simply combines it and is.
For example:
You should try the new restaurant. It’s worth it.
That sounds natural in conversation and informal writing.
The full form is also perfectly natural in conversation:
Trust me. It is worth it.
So the choice between the full form and its contraction is mainly about style, rhythm, and emphasis—not a difference in meaning.
Which One Should You Use?
Use “it is worth it” when you need the complete form.
This is a safe choice for:
- school assignments
- carefully edited writing
- professional communication
- formal explanations
- any situation where you want a complete sentence
Use “it’s worth it” when a natural contraction fits the setting.
Avoid “it worth it” in standard writing and speech.
If you are unsure, remember this simple pattern:
Subject + form of be + worth it
It is worth it.
It was worth it.
It will be worth it.
It would be worth it.
When One Choice Sounds Wrong
The clearest problem is using “it worth it” as a complete sentence:
❌ The course is difficult, but it worth it.
The correction is:
✅ The course is difficult, but it is worth it.
Another common mistake is using does:
❌ Does it worth it?
The correct question is:
✅ Is it worth it?
However, “worth it” can appear by itself in a short conversational reply:
“Should I buy the tickets?”
“Worth it.”
This is an informal shortened response. The fuller meaning is understood from context.
That does not make “it worth it” correct. The two shortened forms work differently: “Worth it” can function as a conversational fragment, while “it worth it” is not the normal complete sentence.
Common Mistakes (and Quick Fixes)
Mistake: It worth it.
Fix: It is worth it.
Mistake: Does it worth it
Fix: Is it worth it?
Mistake: It worth the money.
Fix: It is worth the money.
Mistake: It is worth to buy.
Fix: It is worth buying
Mistake: It was worth to wait.
Fix: It was worth waiting.
The key pattern is simple: after worth, English commonly uses a noun, pronoun, or -ing form.

Dictionary-Style Word Details
Verb
- It worth it: Not a standard complete verb construction. Worth does not function as the ordinary main verb in this phrase.

Word History
The modern phrase it is worth it is built from ordinary English grammatical elements rather than being a separate word with its own special origin.

It worth it does not have a separate standard history as a modern grammatical expression. It is simply the incomplete version created when the linking verb is omitted.

FAQs
Is “it worth it” ever grammatically correct?
No, not as a standard complete sentence. The phrase is missing the linking verb is. Write “it is worth it” or use the natural contraction “it’s worth it.” A short fragment such as “Worth it” is different because its context supplies the missing information.
Is “it is worth it” always the best choice?
Yes, when you need the full standard expression. It works in casual conversation, professional writing, schoolwork, and edited prose. In relaxed conversation, “it’s worth it” is often more natural because English speakers commonly use contractions in ordinary speech.
Does “it’s worth it” mean the same thing?
Yes. “It’s worth it” means the same as “it is worth it.” The difference is only that it’s is the contracted form. Both express the idea that something provides enough value or benefit to justify its cost, effort, time, or difficulty.
Can I say “worth it” by itself?
Yes, in informal conversation or short replies when the meaning is obvious. For example, someone might ask whether a long trip was worthwhile, and you could answer, “Worth it.” This is a conversational fragment, not a replacement for the complete sentence in formal writing.
Why can’t I say “does it worth it”?
Because worth is not functioning as the ordinary action verb in this construction. Use a form of be: “Is it worth it?” The same pattern appears in statements such as “It is worth it” and “It was worth it.”
Can “worth it” be followed by an -ing form?
Yes, but the structure changes slightly. Worth commonly occurs before an -ing form: “It is worth trying” or “The book is worth reading.” Do not normally use “worth to try” or “worth to read” in these patterns.
Conclusion
The correct choice is “it is worth it.” The version “it worth it” leaves out the linking verb is, so it is not a standard complete English sentence.
For everyday conversation, “it’s worth it” is equally correct because it is simply the contracted form.
A useful rule is:
it + form of be + worth it
It is worth it.
It was worth it.
It will be worth it.
Once you recognize is as the verb and worth as the word describing value, the difference becomes straightforward.
