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 track growth rates, price changes, performance improvements, and other comparative metrics.

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 the new and old values, divides by the original value to get a ratio, then multiplies by 100 to convert to a percentage.

3. Importance of Percentage Increase

Details: Percentage increase is fundamental in financial analysis (tracking investment growth), business (measuring sales growth), science (comparing experimental results), and everyday life (tracking price changes).

4. Using the Calculator

Tips: Enter both old and new values. The old value must be greater than zero (can't divide by zero). The calculator handles both increases (positive result) and decreases (negative result).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is simply new value minus old value. Percentage increase shows the change relative to the original size.

Q2: How do I interpret a negative percentage increase?
A: A negative result indicates a percentage decrease rather than an increase.

Q3: What if my old value was zero?
A: The calculation is undefined (division by zero). You can only calculate percentage increase from a non-zero baseline.

Q4: How is this different from percentage points?
A: Percentage points measure absolute difference between two percentages, while percentage increase measures relative change from an original value.

Q5: Can I use this for percentage change between any two numbers?
A: Yes, this works for any measurable quantity where you want to compare the relative change between two values.
