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, and statistics to track growth rates and changes over time.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( \text{New} \) — The current or final value
• \( \text{Old} \) — The original or initial value

Explanation: The formula calculates the relative change between two values by finding the difference, dividing by the original value, and converting to a percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for analyzing growth trends, comparing performance metrics, making investment decisions, and understanding changes in various contexts such as prices, populations, or business metrics.

4. Using the Calculator

Tips: Enter both new and old values. The old value cannot be zero. The calculator will compute the percentage increase and display the result as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What if the old value is zero?
A: The calculation is undefined when the old value is zero, as division by zero is not possible. Please use non-zero values.

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

Q3: How is this different from percentage change?
A: Percentage increase specifically measures growth, while percentage change can be either positive (increase) or negative (decrease).

Q4: What are common applications of percentage increase?
A: Commonly used in salary negotiations, investment returns, price changes, population growth, and performance metrics analysis.

Q5: How should I interpret a 100% increase?
A: A 100% increase means the value has doubled - the new value is exactly twice the old value.
