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 values 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 is divided by the old value, then multiplied by 100 to convert to percentage.

3. Importance of Percentage Increase Calculation

Details: This calculation is fundamental in finance, economics, business analysis, and scientific research to quantify changes.

4. Using the Calculator

Tips: Enter both new and old values. The old value cannot be zero (division by zero is undefined).

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: How do I calculate percentage decrease?
A: The same formula works - a negative result indicates a decrease.

Q3: What if my old value is zero?
A: The calculation is undefined (division by zero). You cannot calculate percentage change from zero.

Q4: 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.

Q5: How is this different from percentage difference?
A: Percentage increase compares new to old, while percentage difference compares any two values without directionality.
