Percentage points and percent are often confused, but they do not mean the same thing. Percentage points describe the simple difference between two percentages. Percent describes a relative change compared with the starting percentage. This difference matters in reports, surveys, interest rates, conversion rates, test scores, and business metrics.

What Percent Means
Percent means a value out of 100. For example, 20% means 20 out of 100.
Percent is used to describe ratios, rates, discounts, growth, and changes.
For the basic formula, read Percentage Formula.
What Percentage Points Mean
Percentage points measure the simple difference between two percentages.
If a rate goes from 10% to 15%, it increased by 5 percentage points.
Percentage points are used when comparing two percentages directly.
Simple Example
Suppose a conversion rate increases from 10% to 15%.
The increase is 5 percentage points because 15 minus 10 equals 5.
But the relative percent increase is 50% because 5 is half of the original 10.
Why This Difference Matters
Saying a rate increased by 5% is not the same as saying it increased by 5 percentage points.
If a rate moves from 10% to 15%, a 5 percentage point increase is correct.
Calling it a 5% increase would be misleading because the relative increase is actually 50%.
Formula for Percentage Point Difference
The formula is: percentage point difference = new percentage - old percentage.
For example, 18% - 12% = 6 percentage points.
This is a direct subtraction between two percentage values.
Formula for Percent Change Between Percentages
The relative percent change formula is: change ÷ old percentage × 100.
If a rate rises from 12% to 18%, the change is 6 percentage points.
The relative percent increase is 6 ÷ 12 × 100, which equals 50%.
Example: Survey Results
Suppose support for an option rises from 40% to 45%.
The increase is 5 percentage points.
The relative percent increase is 5 ÷ 40 × 100, which equals 12.5%.
Example: Interest Rates
If an interest rate rises from 3% to 4%, it increased by 1 percentage point.
The relative increase is 1 ÷ 3 × 100, which equals 33.33%.
This is why percentage points are often clearer when talking about rates.
Example: Conversion Rate
If a conversion rate goes from 2% to 3%, the increase is 1 percentage point.
The relative percent increase is 1 ÷ 2 × 100, which equals 50%.
Both statements can be true, but they mean different things.
When to Use Percentage Points
Use percentage points when comparing two percentages directly.
This is common for rates, shares, test pass rates, survey results, conversion rates, and interest rates.
Percentage points make the absolute difference between percentages clear.
When to Use Percent Change
Use percent change when you want to explain how large the change is relative to the starting value.
For example, moving from 2% to 3% is only 1 percentage point, but it is a 50% relative increase.
For the broader formula, read Percentage Change Formula.
Common Mistakes to Avoid
The first mistake is saying percent when you mean percentage points.
The second mistake is comparing two percentages without explaining the starting value.
The third mistake is using relative percent change when a simple percentage point difference would be clearer.

Conclusion
Percentage points and percent are different. Percentage points measure the direct difference between two percentages.
Percent change measures the relative change compared with the starting percentage. When comparing rates, be clear about which one you mean.
