Expressing percentages in English is a fundamental skill that is useful in various contexts, from everyday conversation to academic discussions and professional settings. Whether you’re discussing statistics, sales figures, or growth rates, knowing how to articulate percentages clearly and accurately is essential. In this article, we’ll explore the different ways to express percentages in English, including common phrases, rules for using hyphens, and tips for clarity.
Common Phrases for Expressing Percentages
When talking about percentages, there are several common phrases you can use to convey the same information. Here are some of the most frequently used expressions:
- Percent: This is the most straightforward way to express a percentage. For example, “The company’s profit margin is 20 percent.”
- Percentage: This term is often used when referring to the concept of percentage itself. You might say, “The increase in sales is a significant percentage.”
- Out of: This phrase is used to denote the total from which the percentage is derived. For instance, “50 out of 100 students passed the exam.”
- Per cent: This is an alternative spelling of the word “percent,” although “percent” is more commonly used in modern English.
- To: When indicating a target or goal, you can use the word “to” followed by the percentage. For example, “We aim to reduce the error rate to 5 percent.”
Rules for Using Hyphens
Hyphens are often used when expressing percentages, but their usage can vary. Here are some guidelines:
- When the word “percent” is part of a compound adjective: Use a hyphen before “percent” when it precedes a noun. For example, “a 20-percent increase in sales.”
- When “percent” is not part of a compound adjective: Do not use a hyphen. For example, “The company’s profit margin is 20 percent.”
- In compound numbers: Use a hyphen to connect the number and “percent.” For example, “a 5.5-percent decrease in revenue.”
Tips for Clarity
To ensure clarity when expressing percentages, consider the following tips:
- Use the appropriate phrase: Choose the phrase that best fits the context of your conversation or writing.
- Be clear about the total: When expressing a percentage, always specify the total from which the percentage is derived. For example, “Two out of five students passed the exam” is clearer than “40 percent passed the exam” without context.
- Avoid ambiguity: If you’re discussing a range of percentages, be clear about whether you’re referring to the lower or upper bound. For example, “The error rate is between 3 and 5 percent” is more precise than “The error rate is 3 to 5 percent.”
Examples

- Profit Margin: “Our profit margin has increased from 15% to 20% over the past year.”
- Growth Rate: “The population of the city has grown by 10% since 2010.”
