1. What is a Percentage Increase Calculator?

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

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

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 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, science, and everyday life to measure growth rates, price changes, performance improvements, and more.

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

Q2: Can I use this for percentage decrease calculations?
A: Yes, the result will automatically show as negative if the new value is smaller than the old value.

Q3: Why is the old value in the denominator?
A: This provides the relative change compared to the original value, making percentages comparable across different scales.

Q4: What if my old value is zero?
A: The calculation is undefined (division by zero). You cannot calculate percentage change from zero.

Q5: How precise are the results?
A: Results are shown with 2 decimal places for precision, but you may round as needed for your application.
