Easy How to Calculate Percentage with Our Calculator

Three Common Percentage Problems Solved Easily

Our percentage calculator is designed to help you solve three common types of percentage problems with ease:

• Finding the Percentage of a Number: This involves calculating a portion of a whole. For example, "What is 15% of 200?"
• Determining What Percentage One Number is of Another: Here, you're figuring out the relative size of two numbers. For example, "30 is what percent of 150?"
• Calculating Percentage Increase or Decrease: This shows the relative change between two values. For example, "What is the percentage increase from 80 to 100?"

Simple Steps to Calculate Percentages

While our calculator makes it incredibly easy, understanding the underlying principles can be helpful. Here are the basic formulas:

• Percentage of a Number: (Percentage / 100) * Number
• Percentage of One Number to Another: (Part / Whole) * 100
• Percentage Increase/Decrease: ((New Value - Original Value) / Original Value) * 100

Examples to Illustrate Percentage Calculations

Let's look at some examples to solidify your understanding:

• Example 1: What is 20% of 500? (20 / 100) * 500 = 100
• Example 2: 45 is what percentage of 90? (45 / 90) * 100 = 50%
• Example 3: What is the percentage increase from 50 to 75? ((75 - 50) / 50) * 100 = 50%

Percentage Tips and Tricks

Here are some quick mental math tricks to help you calculate percentages in your head:

• 10% Trick: To find 10% of a number, simply move the decimal point one place to the left. For example, 10% of 250 is 25.
• 50% Trick: To find 50% of a number, divide it by 2.
• 25% Trick: To find 25% of a number, divide it by 4.

Another fun trick is that x% of y = y% of x. For example, 8% of 50 is the same as 50% of 8, which is easier to calculate.
