1. What is Percentage Increase?

Percentage increase measures how much a quantity has grown relative to its original value, expressed as a percentage. It's commonly used in finance, economics, statistics, and everyday comparisons.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or final value
• Old Value — The original or initial value

Explanation: The formula calculates the difference between values, divides by the original to get relative change, then converts to percentage by multiplying by 100.

3. Importance of Percentage Increase Calculation

Details: Percentage increase helps compare growth rates across different scales, track performance improvements, analyze financial growth, and make data-driven decisions.

4. Using the Calculator

Tips: Enter both new and old values as positive numbers. The old value cannot be zero (division by zero is undefined). Results show how much the value has increased compared to its original amount.

5. Frequently Asked Questions (FAQ)

Q1: What if my result is negative?
A: A negative result indicates a percentage decrease rather than increase.

Q2: How is this different from percentage difference?
A: Percentage increase compares to the original value only, while percentage difference compares to the average of both values.

Q3: What's considered a good percentage increase?
A: This depends entirely on context - a 5% sales increase might be great for a mature business but poor for a startup.

Q4: Can I calculate percentage increase over multiple periods?
A: For compound growth, use the formula for each period sequentially or use exponential growth formulas.

Q5: Why is percentage increase often more meaningful than absolute increase?
A: Percentage provides context relative to the starting size, making comparisons between different scales possible.
