Calculate Percentages Instantly! →This tool helps you solve three common math problems related to percentages:
- Finding the percentage of a number: What is 15% of 200?
- Calculating what percentage one number is of another: 30 is what percent of 150?
- Determining percentage increase or decrease: Going from 80 to 100 is what percent increase?
Understanding the Percentage Formula
At its core, a percentage represents a part of a whole, where the whole is considered 100. The basic percentage formula is:
Percentage = (Part / Whole) × 100
Let's break this down with examples:
Finding a Percentage of a Number
To find X% of Y, you would use: (X / 100) * Y.
For example, to find 20% of 50:
(20 / 100) * 50 = 10
Therefore, 20% of 50 is 10.
Calculating Percentage of One Number to Another
To find what percentage X is of Y, you use: (X / Y) * 100.
For example, to find what percentage 10 is of 50:
(10 / 50) * 100 = 20%
Therefore, 10 is 20% of 50.
Calculating Percentage Increase or Decrease
Percentage Change = ((New Value - Old Value) / Old Value) * 100
For example, if a price increases from $80 to $100:
((100 - 80) / 80) * 100 = 25%
Therefore, the price increased by 25%.
