1. What is Percentage Increase?

Percentage increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used to track growth, inflation, performance improvements, and other comparative measurements.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( \text{New} \) — The current or final value
• \( \text{Old} \) — The original or initial value

Explanation: The formula calculates the relative change between two values by finding the difference, dividing by the original value, and converting to a percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for financial analysis, business growth tracking, academic performance measurement, and understanding changes in various metrics over time.

4. Using the Calculator
