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 mathematics, finance, economics, and statistics to compare growth rates.

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 original value to get the relative change, then converts to a percentage by multiplying by 100.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental for analyzing growth rates, price changes, performance improvements, and many other comparative measurements across various 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).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is simply the difference (New - Old), while percentage increase shows the change relative to the original value.

Q2: What if my old value is zero?
A: Percentage increase is undefined when the old value is zero, as you cannot divide by zero.

Q3: How do I interpret a negative percentage increase?
A: A negative result indicates a percentage decrease rather than an increase.

Q4: What are common applications of percentage increase?
A: Used in calculating price changes, salary raises, investment returns, population growth, and performance improvements.

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