Percentage Point Calculator
Calculate percentage points and understand the difference from percentage change
How to Use This Calculator
Enter Original Percentage
Type the starting percentage value.
Enter New Percentage
Type the ending percentage value.
Compare Both Results
See both percentage points and percentage change to understand the difference.
Formula
Percentage Points = New Percentage - Old Percentage
Percentage Change = ((New - Old) / Old) × 100
Example: Interest rate from 5% to 8%
Percentage Points: 8% - 5% = 3 percentage points
The rate increased by 3 percentage points
Percentage Change: ((8 - 5) / 5) × 100 = 60%
The rate increased by 60% relatively
Example: Unemployment from 10% to 12%
Percentage Points: 12% - 10% = 2 percentage points
Unemployment rose 2 percentage points
Percentage Change: ((12 - 10) / 10) × 100 = 20%
Unemployment increased by 20%
About Percentage Point Calculator
The Percentage Point Calculator helps you understand the crucial difference between percentage points and percentage change. This distinction is important in economics, statistics, finance, and any field where percentages are compared or analyzed.
The Critical Difference
Percentage Points (pp): The absolute arithmetic difference between two percentages. Simple subtraction.
Percentage Change (%): The relative change expressed as a percentage. Shows how much the percentage changed proportionally.
Example: An interest rate increases from 2% to 3%:
- Percentage Point Increase: 1 percentage point (3% - 2%)
- Percentage Change: 50% increase ((3-2)/2 × 100)

Common Mistakes to Avoid
❌ WRONG: "Unemployment increased from 5% to 7%, a 2% increase"
✅ CORRECT: "Unemployment increased from 5% to 7%, a 2 percentage point increase (or a 40% increase)"
The first statement is ambiguous. Did unemployment increase by 2 percentage points (5% → 7%) or by 2% of its original value (5% → 5.1%)? Always specify!
Real-World Applications
News Reporting: "The Fed raised interest rates from 2.5% to 3%, an increase of 0.5 percentage points" is clear and unambiguous, whereas saying "20% increase" might confuse readers.
Political Polling: A candidate's support rises from 40% to 45%. This is a 5 percentage point gain, or a 12.5% increase in support.
Business Metrics: Conversion rate improves from 2% to 3%. That's 1 percentage point improvement, representing a 50% increase in the conversion rate.
Tips for Clear Communication
- Always use "percentage points" (or "pp") when referring to absolute differences
- Use "percent" or "%" when referring to relative changes
- When in doubt, specify both measurements
- In professional writing, avoid ambiguous phrases like "increased by 5%"
- Remember: percentage points add/subtract, percentages multiply/divide
Frequently Asked Questions
What's the difference between 5 percentage points and 5 percent?
5 percentage points is an absolute change (e.g., from 20% to 25%). A 5% change is relative (e.g., from 20% to 21%, which is 5% of 20).
Which measurement should I use?
Use percentage points for absolute changes in percentages (most common in news, economics). Use percentage change when showing relative growth or comparing proportional changes.
Can percentage points be negative?
Yes! A decrease from 30% to 25% is -5 percentage points.
Why is this distinction important?
Confusing the two can lead to serious misunderstandings. A medication reducing risk from 2% to 1% is a 1 percentage point reduction, but a 50% reduction in relative terms - these tell very different stories!
Which sounds more impressive for marketing?
It depends on context. A change from 1% to 2% can be presented as "1 percentage point increase" or "100% increase" - both are accurate but have different impact. Always use the one appropriate for your audience and be honest.
