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, 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:

• \( Increase \) — The amount of increase from original value
• \( Original \) — The starting value before increase
• \( \times 100 \) — Converts the decimal to percentage

Explanation: This formula calculates the proportional increase relative to the original value and expresses it as a percentage for easy comparison and interpretation.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for analyzing growth in business revenue, price changes, population growth, investment returns, and many other quantitative measurements where relative change matters more than absolute numbers.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and percentage points?
A: Percentage increase measures relative growth from an original value, while percentage points measure absolute difference between two percentages.

Q2: Can percentage increase be negative?
A: No, percentage increase is always positive or zero. For decreases, use percentage decrease calculation instead.

Q3: How do I calculate percentage increase without a calculator?
A: Divide the increase by the original value, then multiply by 100. For example: (20 ÷ 100) × 100 = 20% increase.

Q4: What if my original value is zero?
A: Percentage increase is undefined when original value is zero, as division by zero is mathematically impossible.

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