Imbalance vs inbalance has one standard spelling answer: imbalance is correct when you mean a lack of balance, equality, fairness, or proper proportion. Inbalance, written as one word, is not the standard spelling in American English.
For example:
The company needs to address the imbalance between supply and demand.
However, in balance is correct when written as two separate words. It means that different parts are balanced, stable, or properly proportioned:
The new design keeps beauty and function in balance.
Therefore, the spacing and prefix completely change the meaning. Use imbalance for a lack of balance. Use in balance for a balanced state. Avoid the one-word form inbalance in standard edited English.
Quick Answer

The report identifies a serious power imbalance.
Use in balance as a two-word phrase meaning balanced or stable.

Do not write inbalance as one word.

Which Is Correct, Imbalance or Inbalance?
Imbalance is the correct spelling. Inbalance is a common misspelling and is not accepted in standard English. Use imbalance to describe a lack of balance or an uneven condition. For example, There is an imbalance between supply and demand.
What Is an Example of an Imbalance?
An imbalance occurs when two or more things are not equal or properly balanced. For example, A company may face an imbalance between income and expenses, or a person may have a chemical imbalance in the body.
Is It Imbalance or Imbalanced?
Both words are correct, but they have different grammatical roles. Imbalance is a noun that refers to the condition of being uneven or unequal. Imbalanced is an adjective that describes someone or something that lacks balance. For example, The report showed an imbalance in funding, but The table is imbalanced.
Is “Unbalanced” a Correct Word?
Yes. Unbalanced is a correct adjective that means not balanced or unstable. It can describe physical objects, situations, or even a person’s emotional or mental state, depending on the context. It has a different meaning from imbalanced, although both suggest a lack of balance.
Why People Confuse Them
The confusion comes from the negative prefix in-, which often means “not.”
For example:
- inaccurate = not accurate
- incomplete = not complete
- informal = not formal
- invisible = not visible
Therefore, writers may expect balance to become inbalance.
However, English changes the prefix in- to im- before certain consonant sounds, especially b, m, and p.
For example:
- balance → imbalance
- mature → immature
- possible → impossible
- patient → impatient
- perfect → imperfect
The m sound flows more naturally into the following b, m, or p sound. Consequently, the standard word is imbalance, not inbalance.
The correct phrase in balance causes additional confusion. Since the two words sound similar to imbalance, writers may accidentally combine them.
However, their meanings are nearly opposite:
- imbalance = lack of balance
- in balance = state of balance

Is Inbalance A Word?

Pronunciation
Imbalance is generally pronounced:
im-BAL-uhns
The stress falls mainly on the second syllable.
The phrase in balance may sound similar in quick speech. However, speakers can give slightly more separation and emphasis to the two words:

Which One Should You Use?
Choose imbalance if the sentence means:

When One Choice Sounds Wrong
Consider this sentence:
The report found an inbalance between income and expenses.
The writer means a lack of balance. Therefore, the correct spelling is:
The report found an imbalance between income and expenses.
Now consider:
The two sides are imbalance.
This sentence incorrectly uses a noun after are. Write:
The two sides are in balance.
Alternatively, use the adjective:
The two sides are balanced.
Another common mistake is:
The workload is imbalanced between the two employees.
This can work grammatically, but a more natural version may be:
There is a workload imbalance between the two employees.
The choice depends on whether the sentence needs a noun or an adjective.
