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 changes over time.

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 values, divides by the original value to get relative change, then converts to a percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for understanding growth rates in business metrics, investment returns, price changes, and performance improvements. It provides a standardized way to compare changes across different scales.

4. Using the Calculator

Tips: Enter both old and new values in the same units. Values must be positive numbers. The calculator will show the percentage increase (or decrease if negative).

5. Frequently Asked Questions (FAQ)

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

Q2: Can I use this for percentage change between any two numbers?
A: Yes, this works for any positive values where the old value isn't zero (division by zero is undefined).

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

Q4: What's the maximum percentage increase possible?
A: There's no theoretical maximum - as the new value grows much larger than the old, the percentage increase approaches infinity.

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