When talking about if something is valuable, useful, or deserving of the time, money, or effort involved, many English learners wonder if to say “is it worth it” or “does it worth it.” Although both may sound possible at first, only one is grammatically correct in standard English.
The correct expression is “Is it worth it?” We use worth after the verb be when asking if something is valuable or worthwhile. “Does it worth it?” is incorrect because worth does not work as a normal verb in this structure. Understanding this small difference will help you form natural questions and avoid a common grammar mistake.
Quick Answer
“Is it worth it?” is correct. “Does it worth it?” is incorrect in standard English. Use is because worth functions as an adjective in this expression. For example: “Is the price worth it?” or “Is it worth it to wait?”
Why Do People Confuse “Is It Worth It” and “Does It Worth It”?
The confusion usually comes from the use of do/does in English questions.
For example:
- Does it work?
- Does it help?
- Does it matter?
- Does it cost much?
In these examples, work, help, matter, and cost function as verbs.
However, in “Is it worth it?”, the word worth is not being used as an ordinary main verb. The sentence uses the linking verb is.

The First Word: “Is”
Is is a form of the verb be. We use it to connect the subject with information describing it.
In “Is it worth it?”:
- Is = linking verb
- it = subject
- worth it = description of the value or benefit
Examples:
- Is it worth it?
- Is the trip worth it?
- Is this book worth reading?
- Is the price worth paying?
The same pattern appears in statements:
Turn the statement into a question:
The Second Word: “Does”
Does is an auxiliary verb used to form questions with ordinary verbs in the simple present tense.
Examples:
- Does she work here?
- Does he know you?
- Does this help?
- Does it matter?
After does, the main verb normally appears in its base form:
The problem with “Does it worth it?” is that worth is not functioning as the ordinary base-form verb needed in this construction.
Instead, standard English uses:

When Should You Use “Is It Worth It”?

Can You Ever Use “Does” With “Worth”?
Yes, but not in “Does it worth it?”
The important point is that worth can appear in different grammatical structures.
For example:
- How much does it cost?
- What does it cost?
Here, cost is the verb.
With worth, standard expressions include:
- How much is it worth?
- Is it worth the price?
- Is it worth buying?
- Is it worth the effort?
Do not replace is with does simply because you are forming a question.
