1. What is a Percentage Increase Calculator?

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

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

The calculator uses the formula:

\[ \text{Increase} = \left( \frac{\text{New} - \text{Old}}{\text{Old}} \right) \times 100 \]

Where:

A: A negative percentage indicates a decrease rather than an increase between the values.

Q2: How do I interpret a 100% increase?
A: A 100% increase means the new value is exactly double the old value.

Q3: Why can't the old value be zero?
A: Division by zero is mathematically undefined, making percentage change calculations impossible.

Q4: Can I use this for percentage decrease?
A: Yes, the same formula works - a negative result indicates a percentage decrease.

Q5: 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.
