1. What is the Percentage Calculation?

The percentage calculation determines what portion a part is of a whole, expressed as a value out of 100. It's a fundamental mathematical concept used in many real-world applications.

2. How Does the Calculator Work?

The calculator uses the percentage formula:

Where:

• \( Part \) — The portion of the whole you're measuring
• \( Whole \) — The total or reference amount

Explanation: The formula divides the part by the whole to get a decimal, then multiplies by 100 to convert to a percentage.

3. Importance of Percentage Calculation

Details: Percentages are used in statistics, finance, discounts, grades, scientific data, and many everyday situations to compare relative proportions.

4. Using the Calculator

Tips: Enter the part and whole as positive numbers. The whole must be greater than zero. The result shows what percentage the part is of the whole.

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: How do I calculate percentage increase?
A: Use (NewValue - OriginalValue)/OriginalValue × 100. This calculator shows simple proportion percentages.

Q3: What's the difference between percentage and percentile?
A: Percentage is a proportion out of 100, while percentile indicates a position in a distribution (e.g., 90th percentile means scoring higher than 90% of a group).

Q4: Can I calculate percentage of percentage?
A: Yes, but be careful with interpretation. 50% of 80% is 40% of the original whole.

Q5: Why do I get 0% when part is 0?
A: Zero part means zero percentage of the whole, which is mathematically correct.
