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 to analyze growth rates in business, economics, and statistics.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or ending value
• Old Value — The original or starting value

Explanation: The formula calculates the difference between the 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 vital for analyzing growth trends, comparing performance over time, making business decisions, and understanding economic indicators.

4. Using the Calculator

Tips: Enter both new and old values as positive numbers. The old value cannot be zero (division by zero is undefined). Values can be integers or decimals.

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 two percentages, while percentage increase measures relative change from an original value.

Q4: When is percentage increase most useful?
A: When comparing growth rates across different scales or time periods, as it normalizes for the original size.

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