Percentage is a way to express a number as a fraction of 100. It is often denoted using the percent sign (%). The percentage formula is used to find what percent one number is of another number.
The calculator uses the percentage formula:
Where:
Explanation: The formula divides the part by the whole to get a decimal, then multiplies by 100 to convert it to a percentage.
Details: Percentage calculations are fundamental in many areas including finance (interest rates), statistics (data analysis), academics (test scores), and everyday life (discounts, tips).
Tips: Enter the part and whole values. Both must be positive numbers, and the whole cannot be zero. The result will show what percentage the part is of the whole.
Q1: What if my part is larger than the whole?
A: The calculator will still work, showing a percentage greater than 100%. This means the part is larger than the whole.
Q2: Can I calculate percentage decrease?
A: Yes, use this calculator by entering the decreased value as the part and the original value as the whole.
Q3: How do I calculate percentage increase?
A: First find the difference between new and old values, then use that as the part and the original value as the whole.
Q4: Why do I get 0% when part is 0?
A: This is correct - zero is 0% of any whole amount.
Q5: What's the difference between percentage and percentile?
A: Percentage is a proportion out of 100, while percentile indicates relative standing in a distribution (e.g., 90th percentile means scoring higher than 90%).
