News reports and statistics often confuse "percentage points" with "percent change" — they are not the same thing. This tool calculates both, side by side, so the distinction is clear.
How it works
A percentage-point difference is simple subtraction of two percentages (e.g. 45% − 40% = 5 percentage points). Relative percentage change instead divides that same difference by the original percentage: (45−40)/40 × 100 = 12.5%.
- Enter percentage A (%).
- Enter percentage B (%).

Examples
An interest rate change
A rate rising from 40% to 45% is a 5 percentage point increase, but it is a 12.5% relative increase — both are correct, but they answer different questions.
Who should use it
- Interpreting interest rate, tax rate, or unemployment rate changes reported in the news.
- Comparing survey or poll results across two time periods.
Industry applications
- Journalism and statistics reporting
- Economics and policy analysis
- Finance (interest rate changes)
Advantages
- Shows both quantities together so the distinction is unmistakable.
- Useful for spotting misleading percentage reporting.
Limitations
- Relative percentage change is undefined when the baseline percentage is 0%.
Common mistakes to avoid
- Saying a rate "increased by 5%" when it actually increased by 5 percentage points (or vice versa) — these are frequently and incorrectly used interchangeably in media reporting.
Best practices
- Always specify "percentage points" explicitly when reporting the raw difference between two percentages, to avoid ambiguity with percentage change.
Tips
- When you see a percentage change reported, check whether "percentage points" or "percent" was used — the two can tell very different stories about the same underlying numbers.
