1. What is a Percentage Increase Calculator?

Definition: This calculator determines the percentage increase between two values, showing how much a quantity has grown relative to its original amount.

Purpose: It helps analyze growth rates in financial, statistical, scientific, and everyday situations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• New — The current or increased value
• Old — The original or previous value

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

3. Importance of Percentage Increase Calculation

Details: This calculation is fundamental for understanding growth rates, price changes, performance improvements, and statistical analysis.

4. Using the Calculator

Tips: Enter the new and old values (must be positive numbers). The old value cannot be zero.

5. Frequently Asked Questions (FAQ)

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

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 change relative to the original value, while percentage difference compares two values without directionality.

Q4: What's considered a significant percentage increase?
A: Significance depends on context - a 5% price increase might be significant, while a 5% population growth might not be.

Q5: Can I calculate percentage decrease with this?
A: Yes, the result will automatically show as negative when the new value is smaller than the old value.
