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 old value to get relative change, then multiplies by 100 to convert to percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental for analyzing growth rates, comparing changes between different scales, and making data-driven decisions in business and science.

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 new value is smaller than the old value?
A: The calculator will show a negative percentage, indicating a decrease rather than an increase.

Q2: Can I use this for percentage decrease calculations?
A: Yes, a negative result indicates a percentage decrease.

Q3: 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 old value.

Q4: Why is the old value in the denominator?
A: This makes the increase relative to the starting point, allowing meaningful comparisons between different scales.

Q5: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).
