Understanding Percentage Points
📊 What's the Difference?
Percentage Point (pp)
The absolute difference between two percentages. If unemployment rises from 5% to 7%, that's a 2 percentage point increase.
Percentage Change (%)
The relative change expressed as a percentage of the original value. The same 5% to 7% increase is a 40% change in the rate of unemployment.
🌍 Real-World Examples
💰 Interest Rates
3% → 2% = 1 pp decrease or 33.33% decrease
📈 Market Share
15% → 18% = 3 pp gain or 20% increase
📚 Test Scores
60% → 75% = 15 pp improvement or 25% increase
📉 Unemployment
8% → 6% = 2 pp decrease or 25% decrease

Frequently Asked Questions
Q:How does the calculator work?
Enter any two values in the Percentage Points section, and the calculator will automatically compute the other two. All fields are interconnected - changing any value will update the others to maintain mathematical consistency.
Q:Can percentage change be negative?
Yes! A negative percentage change indicates a decrease. For example, going from 100% to 50% is a -50% change (and also -50 percentage points).
Q:What if my initial percentage is 0%?
When Percent #1 is 0%, the percentage change cannot be calculated (division by zero). However, the percentage point change can still be computed normally.
Q:Can I use percentages greater than 100%?
Absolutely! This calculator works with any percentage value, including those above 100% (common in growth rates, inflation, or returns on investment).
Q:What is the "Value difference" section for?
The Value difference section helps you apply percentage calculations to real numeric values. Enter a total value, and it will calculate what Percent #1 and Percent #2 represent in actual numbers, along with the numeric difference between them.
