1. What is Percentage Increase?

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

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Amount — The current or final value
• Old Amount — The original or initial value

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental in finance, economics, business, and statistics for analyzing growth rates, price changes, investment returns, and performance metrics.

4. Using the Calculator

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