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 general data analysis 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 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 essential for analyzing growth trends, comparing performance metrics, calculating inflation rates, evaluating investment returns, and making data-driven decisions in business and research.

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). Results show the percentage increase (positive) or decrease (negative).

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

Q3: What if my old value is zero?
A: The calculation is undefined (division by zero). Percentage change from zero cannot be calculated.

Q4: Can I use this for percentage decrease calculations?
A: Yes, the same formula works for decreases which will show as negative percentages (or you can use absolute value).

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.
