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 in finance, economics, statistics, and general data analysis to compare changes over time.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or final value
• Old Value — The original or starting value

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental for analyzing growth rates, price changes, performance improvements, investment returns, and many other comparative metrics across different fields.

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). Results are rounded to 2 decimal places.

5. Frequently Asked Questions (FAQ)

Q1: What if my old value is zero?
A: The calculation is undefined when old value is zero, as division by zero is impossible. In such cases, consider absolute difference instead.

Q2: What does a negative percentage increase mean?
A: A negative result indicates a percentage decrease rather than increase (when new value is less than old value).

Q3: How is this different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute difference between two percentages.

Q4: When is percentage increase most useful?
A: When comparing changes across different scales, as it normalizes the change relative to the starting point.

Q5: Can percentage increase be over 100%?
A: Yes, when the new value is more than double the old value, the percentage increase exceeds 100%.
