1. What is Percentage Growth?

Percentage growth measures the relative change between an old value and a new value, expressed as a percentage. It's commonly used to track changes in financial metrics, population, sales, and other measurable quantities over time.

2. How Does the Calculator Work?

The calculator uses the percentage growth formula:

Where:

• \( new \) — The new or current value
• \( old \) — The original or previous value

Explanation: The formula calculates the difference between new and old values, divides by the old value to get relative change, then multiplies by 100 to convert to percentage.

3. Importance of Percentage Growth Calculation

Details: Percentage growth is fundamental in business analysis, economics, and scientific research to understand trends, compare changes across different scales, and make data-driven decisions.

4. Using the Calculator

Tips: Enter both old and new values. The old value cannot be zero (division by zero is undefined). Positive results indicate growth, negative results indicate decline.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage growth and percentage points?
A: Percentage growth measures relative change from an original value. Percentage points measure absolute difference between two percentages.

Q2: How do I interpret negative percentage growth?
A: Negative growth indicates a decrease from the original value. For example, -10% means the value decreased by 10% of the original.

Q3: Why can't the old value be zero?
A: Division by zero is mathematically undefined. When the old value is zero, any change is technically infinite percentage growth.

Q4: How is this different from percentage difference?
A: Percentage growth compares to the original value. Percentage difference compares to the average of two values.

Q5: What about compound annual growth rate (CAGR)?
A: CAGR accounts for compounding over multiple periods, while this calculates simple growth between two points in time.
