Calculation Results
Percentage Point Formula: PP Difference = 0% - 0% = 0 pp
Percentage Change Formula: % Change = (0% - 0%) ÷ 0% × 100 = 0.00%
Real-World Examples
Unemployment Rate
Rate increased from 4% to 6%
2 percentage point increase (6% - 4% = 2pp), but 50% relative increase ((6-4)/4 × 100 = 50%)
Interest Rate
Rate decreased from 5% to 3%
2 percentage point decrease (3% - 5% = -2pp), and 40% relative decrease
Tax Rate
Rate increased from 10% to 12%
2 percentage point increase, which is a 20% relative increase in the tax burden
Survey Results
Approval rating from 45% to 52%
7 percentage point increase in approval, representing a 15.6% relative improvement
Percentage Points vs Percent
Percentage Points
Absolute difference between percentages
6% - 4% = 2 percentage points
Percent Change
Relative change as a percentage
(6% - 4%) ÷ 4% × 100 = 50%

Quick Tips
Percentage points measure absolute change
Always specify "pp" for percentage points
Use for rates, surveys, and statistical data
100 basis points = 1 percentage point
Understanding Percentage Points
What are Percentage Points?
A percentage point (or percent point) is the unit for the arithmetic difference of two percentages. It represents the absolute change between two percentage values, not the relative change.
Key Characteristics
- •Measures absolute difference: B% - A%
- •Symbol: pp or percentage points
- •Cannot exceed 100 percentage points for 0-100% scales
- •Independent of the starting percentage
Mathematical Formula
Percentage Point Difference = Percentage₂ - Percentage₁
Percentage Points vs Percent
Example Scenario
Interest rate increases from 2% to 3%
Percentage Point Change: 3% - 2% = 1 pp
Percent Change: (3% - 2%) ÷ 2% × 100 = 50%
When to Use Each
Percentage Points:
- • Interest rate changes
- • Unemployment rate changes
- • Election poll changes
- • Survey result differences
Percent Change:
- • Sales growth
- • Price increases
- • Population changes
- • Revenue variations
Advanced Applications
Financial Markets
Interest rate changes, yield spreads, and credit ratings are typically expressed in basis points or percentage points.
Example: "The Fed raised rates by 25 basis points (0.25 percentage points)"
Political Polling
Poll results and approval ratings use percentage points to show absolute changes in support.
Example: "Support increased by 5 percentage points from 45% to 50%"
Economic Indicators
GDP growth, inflation rates, and unemployment statistics use percentage points for comparisons.
Example: "Unemployment fell by 1.2 percentage points to 4.5%"
