1. What is Percentage Increase?

Percentage increase measures how much a quantity has grown relative to its original value. It's expressed as a percentage of the original number and is commonly used to track growth rates in business, economics, and statistics.

2. How the Calculator Works

The calculator uses the percentage increase formula:

Where:

• Final Value — The new, increased number
• Initial Value — The original number

Example: If a product's price increases from $50 to $75, the calculation would be: (75-50)/50 × 100 = 50% increase.

3. Practical Applications

Details: Percentage increase is widely used in:

• Financial analysis (revenue growth, stock prices)
• Sales performance tracking
• Population growth studies
• Price inflation calculations
• Scientific measurements

4. Using the Calculator

Tips: Enter both numbers in the same units. The initial number cannot be zero (division by zero is undefined). The result shows how much the second number has increased compared to the first, expressed as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is the simple difference (Number2 - Number1), while percentage increase shows this difference relative to the original value.

Q2: Can the result be negative?
A: Yes, if Number2 is less than Number1, the result will be negative, indicating a percentage decrease.

Q3: How is percentage increase different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute difference between two percentages.

Q4: What if my initial value is zero?
A: The calculation is undefined (division by zero). You can only calculate percentage increase from a non-zero base.

Q5: How do I calculate percentage increase over multiple periods?
A: For compound growth, use the formula: [(Final/Initial)^(1/periods) - 1] × 100.
