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 everyday life to track growth or expansion.

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 the new and old values, divides by the original 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 crucial for understanding growth rates in business revenue, investment returns, price changes, population growth, and many other applications where relative change matters more than absolute change.

4. Using the Calculator

Tips: Enter both values as positive numbers. The old value cannot be zero (division by zero is undefined). The calculator handles both increases (positive result) and decreases (negative result).

5. Frequently Asked Questions (FAQ)

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

Q2: Can the result be negative?
A: Yes, if the new value is smaller than the old value, the result will be negative, indicating a percentage decrease.

Q3: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).

Q4: Why can't the old value be zero?
A: Division by zero is mathematically undefined, making percentage change calculations impossible when starting from zero.

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.
