1. What is Percentage Increase?

Percentage increase measures the relative growth from an original value to a new value, expressed as a percentage. It helps quantify changes in various contexts like prices, quantities, or measurements over time.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( \text{New} \) — The new or current value
• \( \text{Old} \) — The original or previous value

Explanation: The formula calculates the difference between new and old values relative to the original value, then converts it to a percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is widely used in finance, economics, business analysis, and scientific research to measure growth rates, inflation, performance improvements, and other comparative changes.

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 between the two values.

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, showing a reduction from the original value.

Q2: Can I use this calculator for financial calculations?
A: Yes, this calculator is suitable for calculating price increases, investment growth, revenue changes, and other financial metrics.

Q3: What's the difference between percentage increase and absolute increase?
A: Absolute increase shows the numerical difference (New - Old), while percentage increase shows the relative change as a percentage of the original value.

Q4: How do I interpret a 100% increase?
A: A 100% increase means the new value is exactly double the original value.

Q5: What if my old value is zero?
A: The calculation is undefined when the old value is zero, as division by zero is not possible. Please ensure the old value is greater than zero.
