1. What is Percentage Growth?

Percentage growth measures how much a value has increased or decreased relative to its original amount, expressed as a percentage. It's commonly used in finance, economics, business metrics, and scientific measurements to track changes over time.

2. How Does the Calculator Work?

The calculator uses the percentage growth formula:

\[ \text{Percentage Growth} = \left( \frac{\text{End Value} - \text{Start Value}}{\text{Start Value}} \right) \times 100\% \]

Where:

End Value — The current or final measurement
Start Value — The original or initial measurement

Explanation: The formula calculates the relative change between two values by comparing the difference to the original amount.

3. Importance of Percentage Growth Calculation

Details: Percentage growth is fundamental for analyzing trends, comparing performance across different scales, making investment decisions, and setting business targets. It provides a standardized way to express changes regardless of the absolute values involved.

4. Using the Calculator

Tips: Enter the original (start) value and the new (end) value. The calculator will show the percentage increase or decrease. Note that the start value cannot be zero as division by zero is undefined.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage growth mean?
A: A negative result indicates a decrease from the start value to the end value.

Q2: How is percentage growth different from percentage points?
A: Percentage growth measures change relative to the original value, while percentage points measure absolute differences between percentages.

Q3: What's the difference between percentage growth and compound growth?
A: Percentage growth calculates simple one-period change, while compound growth accounts for growth on previously accumulated growth over multiple periods.

Q4: Can percentage growth exceed 100%?
A: Yes, when the end value is more than double the start value, the percentage growth will exceed 100%.

Q5: How do I calculate percentage growth over multiple periods?
A: For annual growth rates, you would typically use the compound annual growth rate (CAGR) formula instead.
