1. What is a Percentage Increase Calculator?

Definition: This calculator determines the percentage increase from an old value to a new value.

Purpose: It helps analyze growth rates, price changes, performance improvements, and other comparative measurements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Increase — Percentage growth from old to new value
• New — The current or updated value
• Old — The original or previous value

Explanation: The difference between new and old is divided by the old value to get relative change, then multiplied by 100 to convert to percentage.

3. Importance of Percentage Increase Calculation

Details: This calculation is fundamental in finance, economics, business analysis, and scientific research to measure growth and changes.

4. Using the Calculator

Tips: Enter both old and new values. Values must be positive numbers. The result shows 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 increase.

Q2: Can I use this for any units?
A: Yes, as long as both values are in the same units (dollars, pounds, etc.).

Q3: What's the difference between percentage increase and percentage points?
A: Percentage increase is relative to the original value, while percentage points are absolute differences between percentages.

Q4: How do I calculate percentage decrease?
A: The same formula works - it will automatically show as negative if new value is smaller.

Q5: What if my old value is zero?
A: The calculation is undefined (division by zero), so the calculator requires positive values.
