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, change, or improvement between two values in various contexts like finance, statistics, and business.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is crucial for analyzing growth rates, price changes, performance improvements, and statistical trends.

4. Using the Calculator

Tips: Enter both new and old values. The old value must be greater than zero. Values can represent any measurable quantity (sales, population, test scores, etc.).

5. Frequently Asked Questions (FAQ)

Q1: What does a negative result mean?
A: A negative result indicates a percentage decrease rather than increase.

Q2: Why can't the old value be zero?
A: Division by zero is mathematically undefined, making percentage change calculations impossible.

Q3: How is this different from percentage difference?
A: Percentage increase compares new to old, while percentage difference compares any two values without directionality.

Q4: What's considered a "good" percentage increase?
A: This depends entirely on context - in finance higher is better, in error rates lower is better.

Q5: Can I use this for percentage decrease calculations?
A: Yes, when new value is less than old value, the result will automatically show the percentage decrease.
