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, statistics, and general data analysis to compare growth rates.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

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

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for understanding growth rates in business metrics (revenue, profits), analyzing investment returns, tracking performance improvements, and comparing changes across different scales.

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value must be greater than zero (division by zero is undefined). Results are rounded to 2 decimal places.

5. Frequently Asked Questions (FAQ)

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

Q2: How is this different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute difference between percentages.

Q3: What's the maximum percentage increase possible?
A: There's no theoretical maximum. A value increasing from 1 to 2 is a 100% increase, from 1 to 3 is 200%, etc.

Q4: Can I use this for percentage change between any two numbers?
A: Yes, though if the old value is larger, you'll get a percentage decrease (negative value).

Q5: Why multiply by 100 at the end?
A: Multiplication by 100 converts the decimal fraction to a percentage (e.g., 0.25 becomes 25%).
