1. What Is Percentage Growth?

Percentage growth measures the relative change between an old value and a new value, expressed as a percentage of the old value. It's commonly used in finance, economics, business metrics, and scientific measurements.

2. How The Calculation Works

The percentage growth formula:

Where:

• New Value — The current or ending measurement
• Old Value — The previous or starting measurement

Explanation: The formula calculates the difference between values, divides by the original to get relative change, then converts to percentage by multiplying by 100.

3. Importance Of Growth Measurement

Details: Percentage growth provides standardized comparison across different scales, allowing meaningful analysis of changes whether dealing with small or large numbers.

4. Using The Calculator

Tips: Enter both new and old values. The old value cannot be zero (division by zero is undefined). Negative values are acceptable for calculating growth rates.

5. Frequently Asked Questions (FAQ)

Q3: What's the difference between growth rate and percentage growth?
A: They're often used interchangeably, but growth rate typically refers to change over time (e.g., annual growth rate).

Q4: How do you calculate compound annual growth rate (CAGR)?
A: CAGR requires time period and uses formula: [(Ending Value/Beginning Value)^(1/Periods) - 1] × 100.

Q5: What are common applications of percentage growth?
A: Used in financial analysis (revenue growth), population studies, investment returns, business metrics, and scientific measurements.
