Understanding the Percentage Formula
While our calculator does the heavy lifting, understanding the underlying formula can be helpful. The basic percentage formula is:
Percentage = (Part / Whole) * 100
Where:
- "Part" is the specific value you're interested in.
- "Whole" is the total or reference value.
For example, if you want to find what percentage 25 is of 100:
Percentage = (25 / 100) * 100 = 25%

- Retail: Determining sale prices and markups. You may even want to work out percentage discount.
- Statistics: Analyzing data and trends.
- Education: Calculating grades and test scores.
- Health: Monitoring body fat percentage and weight loss progress.
Beyond the Basics: Percentage Increase and Decrease
Understanding percentage change is crucial for analyzing trends and making comparisons. Whether it's tracking the growth of your business or monitoring changes in your weight, percentage increase and decrease calculations are essential.
Percentage Increase Formula:
Percentage Increase = [(New Value - Old Value) / Old Value] * 100
Percentage Decrease Formula:
Percentage Decrease = [(Old Value - New Value) / Old Value] * 100
