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 many other fields to track growth or change 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 initial value

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for understanding growth rates, comparing changes between different scales, and making data-driven decisions in business and research.

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).

5. Frequently Asked Questions (FAQ)

Q1: What if my percentage increase is negative?
A: A negative result indicates a percentage decrease rather than an increase.

Q2: How is percentage increase different from absolute increase?
A: Absolute increase shows the numerical difference, while percentage increase shows the relative change compared to the original value.

Q3: What's the maximum possible percentage increase?
A: There's no upper limit - percentage increase can be any positive number, including values over 100%.

Q4: Can I calculate percentage increase between two negative numbers?
A: Yes, but interpretation can be tricky - the sign of the result depends on whether the value became more or less negative.

Q5: How is this different from percentage points?
A: Percentage points measure absolute difference between percentages, while percentage increase measures relative change from an original value.
