The calculator uses the percentage formula:
Where:
Explanation: The formula calculates what portion a value (part) is of another value (total), then expresses that ratio as a percentage.
Details: Percentages are fundamental in statistics, finance, science, and everyday life. They allow easy comparison between different quantities and are essential for understanding proportions, discounts, interest rates, and many other concepts.
Tips: Enter the part value and total value. Both must be positive numbers, and the total cannot be zero. The calculator will show what percentage the part is of the total.
Q1: What if my part is larger than the total?
A: The calculator will still work and give a percentage greater than 100%, indicating the part exceeds the total.
Q2: How do I calculate percentage increase?
A: Percentage increase = [(New Value - Original Value) / Original Value] × 100
Q3: What's the difference between percentage and percentile?
A: Percentage is a proportion out of 100, while percentile indicates the percentage of values that fall below a certain point in a distribution.
Q4: How do I convert a percentage back to a decimal?
A: Divide the percentage by 100 (e.g., 25% = 0.25).
Q5: Why do we multiply by 100 in percentage calculations?
A: Multiplying by 100 converts the decimal fraction to a percentage, which is easier to understand and compare.
