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 starting value

Explanation: The formula calculates the difference between 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

Details: Percentage increase is crucial for analyzing growth rates, comparing changes across different scales, and making data-driven decisions in business, investments, and scientific research.

4. Using the Calculator

Tips: Enter both new and old values. The old value cannot be zero (division by zero is undefined). Values can be any positive numbers (currency, quantities, measurements, etc.).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is simply new value minus old value, while percentage increase shows the change relative to the original value.

Q2: How do I interpret a negative percentage increase?
A: A negative result indicates a percentage decrease rather than increase.

Q3: Can I use this for percentage change between any two values?
A: Yes, the formula works for any two positive values where the denominator isn't zero.

Q4: Why multiply by 100 in the formula?
A: Multiplying by 100 converts the decimal result to a percentage (e.g., 0.25 becomes 25%).

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.
