Could care less or Couldn't care less: Which Is Correct?
Updated · Which One Is Correct editorial team
Quick answer: The correct phrase is couldn't care less, meaning you have reached the absolute bottom of your concern. Could care less suggests you still have some interest left, which contradicts the intended meaning of total indifference. Stick with the negative form for accuracy.
The Short Answer
Couldn't care less is the logical form because it states that your level of care has dropped to zero and cannot go any lower.
People often confuse them by treating the phrase as a fixed idiom where the negative word is dropped for stylistic flair, but this change actually flips the meaning to imply you still care somewhat.
Side-by-Side Comparison
| Form | Status | Use it when |
|---|---|---|
| Couldn't care less | Correct | You want to express total apathy or zero interest in a topic. |
| Could care less | Incorrect | You do not, as it logically means you possess remaining capacity to care. |
| Phrase Type | Idiom | Both function as adverbial phrases modifying a subject's level of interest. |
| Regional Note | US/UK | The error is common in informal American speech but remains logically flawed everywhere. |
