2. How Does the Percentage 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)

A: You'll get a percentage >100%, which means the part exceeds the whole (possible in growth comparisons).

Q2: Can I calculate percentage decrease?
A: Yes, when the part represents a decrease from the whole, you'll get a percentage <100%.

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 difference between percentages (e.g., 5% to 7% is a 2 percentage point increase).

Q5: What's the percentage if whole is zero?
