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 in financial, statistical, and scientific contexts.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or final measurement
• Old Value — The original or initial measurement

Explanation: The formula calculates the relative difference between two values as a percentage of the original value.

3. Importance of Percentage Increase Calculation

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

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value must be non-zero to avoid division by zero errors.

Q2: How is this different from percentage difference?

A: There's no upper limit - percentage increase can be any positive value (100% means doubled, 200% means tripled, etc.)

Q4: Can I use this for financial calculations?
A: Yes, this is commonly used to calculate investment returns, price increases, revenue growth, etc.

Q5: What if my old value is zero?
A: The calculation is undefined (division by zero). You cannot calculate percentage increase from zero.
