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 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:

Where:

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

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

3. Importance of Growth Calculation

Details: Percentage growth is essential for comparing changes across different scales, analyzing trends, making business decisions, and evaluating performance metrics.

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value must be greater than zero (division by zero is undefined).

5. Frequently Asked Questions (FAQ)

Q1: What does negative growth percentage mean?
A: A negative result indicates a decrease rather than growth between the old and new values.

Q2: What's the difference between percentage growth and percentage change?
A: They use the same formula. "Growth" typically implies positive change, while "change" can be positive or negative.

Q3: How do I interpret a 100% growth?
A: 100% growth means the value has doubled (new value is 200% of the original).

Q4: Can I calculate growth over multiple periods?
A: For compound growth over multiple periods, you would use the compound growth rate formula instead.

Q5: Why is the old value in the denominator?
A: Using the old value as the base (denominator) shows the change relative to the starting point.
