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 to analyze growth rates in financial, economic, and scientific data.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or ending value
• Old Value — The original or starting value

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

3. Importance of Percentage Increase Calculation

Details: Calculating percentage increase is essential for understanding growth trends, comparing performance over time, making investment decisions, and analyzing statistical data.

4. Using the Calculator

Tips: Enter both the new and old values as positive numbers. The old value cannot be zero (division by zero is undefined). Results are rounded to 2 decimal places.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage increase mean?
A: A negative result indicates a percentage decrease rather than an increase.

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

Q3: Can I use this for year-over-year growth calculations?
A: Yes, this is commonly used for YoY growth by comparing current year values to previous year values.

Q4: What if my old value is zero?
A: The calculation is undefined when the old value is zero, as you cannot divide by zero.

Q5: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).
