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, and statistics to analyze 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 new and old values, divides by the old value to get relative change, then converts to percentage by multiplying by 100.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is crucial for analyzing growth in investments, sales, prices, population, and other metrics. It allows comparison between different scales and time periods.

4. Using the Calculator

Tips: Enter both new and old 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 the simple difference (New - Old), while percentage increase shows the relative change compared to the original value.

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

Q3: 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.

Q4: What if my old value is zero?
A: The calculation is undefined (division by zero). Consider using absolute difference instead in such cases.

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