You’ve probably paused mid-sentence wondering: per cent or percent—which one is actually correct? You’re not alone. This small spelling difference can trip up even experienced writers, especially when switching between British and American English.
In this guide, we’ll break down is it per cent or percent, explain when to use each, and give you simple rules so you never second-guess yourself again.
Per Cent or Percent: What’s the Difference?
At first glance, the difference between per cent and percent looks purely stylistic—but it’s actually tied to regional spelling conventions.
- Percent (one word) → Used in American English
- Per cent (two words) → Used in British English
Both mean exactly the same thing: “out of 100.”
So if you’re asking, is it per cent or percent, the answer depends on your audience and writing style.
Why Are There Two Versions?
The term originates from the Latin phrase “per centum,” meaning “by the hundred.” Over time:
- British English retained the two-word format: per cent
- American English simplified it into one word: percent
This evolution is similar to other spelling differences like “colour” vs. “color” or “organise” vs. “organize.”
When Should You Use “Percent”?
Use percent if you’re writing for:
- American audiences
- U.S.-based websites or publications
- Academic or professional content following American English rules
Example:
- The company saw a 20 percent increase in revenue.
When Should You Use “Per Cent”?
Use per cent when your content is aimed at:
- British, Australian, or international audiences using UK English
- Publications that follow British spelling conventions
Example:
- About 15 per cent of the population prefers tea over coffee.
Quick Rule to Remember
If you’re still unsure whether to use per cent or percent, follow this simple rule:
Match your spelling to your audience.
Consistency matters more than which version you choose.
Percent vs % Symbol: What’s Better?
Another common confusion is whether to write the word or use the symbol (%).
Use the symbol (%) when:
- Writing statistics or data-heavy content
- Creating charts, reports, or technical documents
Use the word when:
- Writing formal essays
- Maintaining a conversational tone
Example:
- Formal: Only 10 percent of users completed the survey.
- Data-driven: Only 10% of users completed the survey.
Common Mistakes to Avoid
Here are a few errors people often make:
- Mixing both styles in one article
- Writing “per cent” for American audiences
- Using inconsistent formatting (e.g., switching between % and words randomly)
Pro Tip:
Pick one style and stick with it throughout your content.
