1. What is Percentage Increase?

Percentage increase measures the relative growth from an original value to a new value, expressed as a percentage. It quantifies how much a value has grown compared to its starting point.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( Increase \) — The amount of increase (new value - original value)
• \( Original \) — The starting or baseline value
• \( 100 \) — Conversion factor to express result as percentage

Explanation: This formula calculates the proportional increase relative to the original value and converts it to a percentage for easier interpretation.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is widely used in finance, economics, business, statistics, and everyday life to measure growth rates, performance improvements, price changes, and many other comparative analyses.

4. Using the Calculator

Tips: Enter the original value and the increase amount in the same units. Both values must be positive numbers. The calculator will automatically compute the percentage increase.

5. Frequently Asked Questions (FAQ)

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

Q2: Can percentage increase be over 100%?
A: Yes, if the increase is greater than the original value, the percentage increase will exceed 100%.

Q3: How do I calculate percentage increase manually?
A: Divide the increase by the original value, then multiply by 100. For example: (50/200) × 100 = 25%.

Q4: What if my original value is zero?
A: Percentage increase cannot be calculated when the original value is zero, as division by zero is undefined.

Q5: How is percentage increase used in real life?
A: Common applications include calculating salary raises, investment returns, sales growth, population increases, and price inflation.
