Understanding the Percentage Formula

While our calculator does the heavy lifting for you, it's helpful to understand the basic percentage formula. A percentage represents a part of a whole, expressed as a fraction of 100.

The core formula we leverage is:
Percentage = (Part / Whole) * 100

Our tool automates this calculation for various scenarios:

  • Finding a Percentage of a Number: Solves for "Part" when you know the Percentage and Whole.
  • Finding What Percentage One Number is of Another: Solves for "Percentage" when you know the Part and Whole.
  • Calculating Percentage Change: Involves a slightly modified formula to determine the increase or decrease between two values, relative to the initial value.

Examples of Percentage Calculations

  3. Example 3: Tracking Website Conversion Rate
