1. What is Percentage Increase?

Percentage increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used in finance, economics, statistics, and everyday life to track growth and changes over time.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( New \) — The current or final value
• \( Old \) — The original or starting value

Explanation: The formula calculates the difference between new and old values, divides by the original value to get the relative change, then multiplies by 100 to convert to percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for analyzing growth rates, comparing performance metrics, tracking inflation, evaluating investment returns, and making data-driven decisions in business and personal finance.

4. Using the Calculator

Tips: Enter both new and old values in the same units. Values must be positive numbers. The calculator will show the percentage increase, with positive values indicating growth and negative values indicating decrease.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage increase mean?
A: A negative percentage increase indicates a percentage decrease, meaning the value has gone down from the original amount.

Q2: How is percentage increase different from percentage points?
A: Percentage increase measures relative change from a base value, while percentage points measure absolute difference between two percentages.

Q3: Can percentage increase exceed 100%?
A: Yes, percentage increase can exceed 100% when the new value is more than double the old value.

Q4: What if the old value is zero?
A: The calculation is undefined when the old value is zero, as division by zero is mathematically impossible.

Q5: How is this used in real-world scenarios?
A: Common applications include calculating salary increases, stock price changes, population growth, sales growth, and inflation rates.
