1. What is a Percentage Increase Calculator?

Definition: This calculator determines the percentage increase between two values (old and new).

Purpose: It helps measure growth, improvement, or change between two quantities in percentage terms.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• New — The current or final value
• Old — The original or initial value

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is widely used in finance, economics, business, statistics, and everyday life to measure growth rates, price changes, performance improvements, and more.

4. Using the Calculator

Tips: Enter both values (new and old). The old value must be greater than zero. The result shows the percentage increase (positive) or decrease (negative).

5. Frequently Asked Questions (FAQ)

Q1: What if my old value is zero?
A: The calculation is undefined when old value is zero, as division by zero is impossible.

Q2: What does a negative result mean?
A: A negative result indicates a percentage decrease rather than increase.

Q3: How is this different from percentage difference?
A: Percentage increase compares new to old specifically, while percentage difference is symmetrical between two values.

Q4: Can I use this for financial calculations?
A: Yes, this is commonly used for calculating investment returns, price changes, and revenue growth.

Q5: What's the maximum percentage increase possible?
A: There's no theoretical maximum - the percentage can be any positive number depending on how much larger the new value is compared to the old.
