PUTTING IT INTO PRACTICE
Percentage Point: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Original rate (%) | 10 |
| New rate (%) | 15 |
| Result | 5 percentage points |
- Check the input labels and enter the example values above.
- Apply the relationship: Percentage points = new rate − original rate.
- The result is 5 percentage points, rounded for display.
How to interpret your result
A move from 10% to 15% is five percentage points, not a five-percent relative increase.
Choose the base before calculating. Percentage points compare two rates by subtraction, while percentage change divides a difference by an original value. Successive discounts apply one after another rather than adding together.
Frequently asked questions
Should I use percentage change or percentage points?

Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
