1. What is Percentage Increase?

Percentage increase measures the relative growth from an original value to a new value, expressed as a percentage. It quantifies how much a value has grown compared to its original amount.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

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

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is widely used in finance, economics, business, statistics, and everyday life to measure growth rates, performance improvements, price changes, and many other comparative analyses.

4. Using the Calculator

Tips: Enter the original value and the new value. Both values must be positive numbers, and the old value cannot be zero (division by zero is undefined).
