1. What is Percentage Increase?

Percentage increase measures how much a quantity has grown relative to its original value, expressed as a percentage. It's commonly used to compare growth rates in business, economics, science, and everyday life.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( \text{Number1} \) — Original/initial value
• \( \text{Number2} \) — New/final value

Explanation: The formula calculates the difference between two numbers, divides by the original number, and converts to a percentage by multiplying by 100.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for analyzing growth trends, comparing performance metrics, making investment decisions, and understanding changes in prices or quantities over time.

4. Using the Calculator

Tips: Enter both numbers (must be positive). The calculator will show the percentage increase from Number1 to Number2. If Number2 is smaller than Number1, the result will be negative (indicating a decrease).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is the simple difference (Number2 - Number1), while percentage increase shows the change relative to the original value.

Q2: Can the result be negative?
A: Yes, if Number2 is less than Number1, the result is negative, indicating a percentage decrease.

Q3: How is this different from percentage points?
A: Percentage points measure absolute difference between percentages, while percentage increase measures relative change from an original value.

Q4: What if my original number is zero?
A: The calculation is undefined (division by zero). Percentage change can't be calculated when starting from zero.

Q5: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).
