1. What is a Percentage Calculator?

Definition: This calculator computes the percentage that one number represents of another number.

Purpose: It helps in various mathematical, financial, and statistical calculations where relative proportions need to be determined.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Percentage — The result expressed as a percentage
• Part — The portion of the whole you're measuring
• Whole — The total or reference amount

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: Percentage calculations are fundamental in finance (interest rates), statistics (data analysis), academics (grading), and everyday life (discounts, tips).

4. Using the Calculator

Tips: Enter the part and whole values. The whole must be greater than zero. The result will be displayed as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What if my part is larger than the whole?
A: The calculator will still work, showing a percentage greater than 100%.

Q2: Can I calculate percentage decrease?
A: Yes, when the part represents a decrease from the whole, the result will be a negative percentage.

Q3: What's the difference between percentage and percentile?
A: Percentage is a proportion out of 100, while percentile indicates relative position in a distribution.

Q4: How do I calculate percentage points?
A: Percentage points represent absolute differences between percentages (e.g., 5% to 7% is a 2 percentage point increase).

Q5: What about percentage of a percentage?
A: Multiply the percentages (e.g., 20% of 50% is 0.20 × 0.50 = 0.10 or 10%).
