Formula for Percentage Calculations

The percentage calculation essentially revolves around a few basic formulas. Here are the most commonly used methods:

• To find a percentage of a number: (Part / Whole) x 100 = Percentage
• To find what percentage one number is of another: (Part / Whole) x 100 = Percentage
• To calculate a percentage increase: (New Value – Original Value) / Original Value x 100 = Percentage Increase
• To calculate a percentage decrease: (Original Value – New Value) / Original Value x 100 = Percentage Decrease

Example Calculation

Let’s say you want to find out what 20% of 250 is. Here’s how you do it:

1. Use the formula: (Part / Whole) x 100 = Percentage
2. Convert the equation: (X / 250) x 100 = 20
3. Rearranging gives: X = (20/100) * 250 = 50

So, 20% of 250 is 50.
