1. What is Percentage Increase?

Percentage increase measures the relative growth from an original value to a new value, expressed as a percentage. It's commonly used in finance, economics, statistics, and everyday calculations to understand growth rates and changes over time.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( \text{New} \) — The new or current value
• \( \text{Old} \) — The original or previous 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 trends, comparing performance metrics, calculating inflation rates, assessing investment returns, and making data-driven decisions in business and personal finance.

4. Using the Calculator

Tips: Enter both old and new values in the same units. Ensure old value is greater than zero to avoid division by zero errors. The result shows the percentage increase from old to new value.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and percentage change?
A: Percentage increase specifically measures growth, while percentage change can be positive (increase) or negative (decrease).

Q2: Can percentage increase be more than 100%?
A: Yes, if the new value is more than double the old value, the percentage increase will exceed 100%.

Q3: What if the old value is zero?
A: Percentage increase is undefined when old value is zero, as it involves division by zero.

Q4: How is percentage increase used in real life?
A: Common applications include salary increases, stock price changes, population growth, sales growth, and inflation calculations.

Q5: What does a negative percentage increase mean?
A: A negative result indicates a percentage decrease rather than increase, meaning the value has gone down.
