1. What is a Percentage Calculator?

Definition: This calculator determines what percentage one number is of another number.

Purpose: It helps with mathematical calculations, financial analysis, statistics, and everyday percentage problems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Part — The portion you want to find the percentage of (unitless)
• Whole — The total or reference amount (unitless)

Explanation: The part is divided by the whole to get a decimal value, which is then multiplied by 100 to convert it to a percentage.

3. Importance of Percentage Calculation

Details: Percentages are fundamental in mathematics, finance, statistics, and everyday life for comparing proportions and changes.

4. Using the Calculator

Tips: Enter the part and whole values (both must be positive numbers). The whole cannot be zero.

5. Frequently Asked Questions (FAQ)

Q1: What if my part is larger than the whole?
A: The calculator will show a percentage greater than 100%, indicating the part exceeds the whole.

Q2: Can I calculate percentage decrease?
A: Yes, enter the decreased value as the part and the original value as the whole.

Q3: What's the difference between percentage and percent point?
A: Percentage is relative to the whole, while percent points are absolute differences between percentages.

Q4: How do I calculate reverse percentages?
A: If you know the percentage and whole, the part = (percentage/100) × whole.

Q5: Why do I get an error when whole is zero?
A: Division by zero is mathematically undefined, so the whole must be greater than zero.
