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 life to track growth rates.

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 starting value

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for understanding growth rates in business metrics (sales, profits), investments (stock performance), population studies, and scientific measurements.

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).

5. Frequently Asked Questions (FAQ)

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

Q2: Can percentage increase be negative?
A: Yes, if the new value is smaller than the old value, the result will be negative, indicating a percentage decrease.

Q3: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).

Q4: What if my old value was zero?
A: Percentage change from zero is undefined mathematically, as it would require division by zero.

Q5: How is this different from percentage points?
A: Percentage points measure absolute difference between percentages, while percentage increase measures relative change from an original value.
