Percentage comparison involves assessing the relative difference between two or more percentages. This can be as simple as determining which of two percentages is larger or more complex, such as calculating the percentage difference between two values.
For instance, you might want to know:
- What percentage of a number is (e.g., what is 15% of 200?).
- What percentage one number is of another (e.g., 30 is what percent of 150?).
- How much something increased or decreased in percentage terms (e.g., going from 80 to 100).
How to Compare Percentages Effectively
Here are some strategies for effective percentage comparison:
- Understand the Base: Always be clear about what the percentages are based on. A 10% increase on a small number is very different from a 10% increase on a large number.
- Calculate Percentage Change: To compare changes, use the percentage change formula:
((New Value - Old Value) / Old Value) * 100. - Use a Percentage Calculator: Our percentage calculator can quickly solve these problems. It offers a user-friendly interface and accurate results, saving you time and effort.
Percentage Difference vs. Percentage Change
It's important to distinguish between percentage difference and percentage change.
- Percentage Difference: This is used to compare two numbers where neither is considered the "original" value. The formula is:
(|V1 - V2| / [(V1 + V2)/2]) * 100. As seen on other sites offering a Percentage Difference Calculator, the order of the numbers doesn't matter. - Percentage Change: This is used when you want to find the change from an old number to a new number. The formula is:
((New Value - Old Value) / Old Value) * 100.
Real-World Applications

- Health: Tracking weight loss (5 percent weight loss calculator), changes in health metrics, and medication dosages.
- Education: Calculating grades, comparing test scores, and assessing academic progress.
Examples of Percentage Comparison
Let's look at some examples:
- Example 1: Suppose you're deciding between two discounts: 20% off a $50 item and 30% off a $30 item. Which is the better deal?
- 20% off $50 = $10 savings.
- 30% off $30 = $9 savings.
- The 20% off $50 item saves you more money.
- Example 2: If your portfolio increased from $10,000 to $12,000, what is the percentage increase?
- Percentage increase =
(($12,000 - $10,000) / $10,000) * 100 = 20%.
- Percentage increase =
- Example 3: Find the percentage difference between 5 and 7.
- Percentage difference =
(|5 - 7| / [(5 + 7)/2]) * 100 = 33.33%.
- Percentage difference =
