If you're struggling to calculate percentages or understand how they work, this beginner's guide is perfect for you. We break down everything you need to know about percentages from the basics to real-world scenarios and provide tips and tricks to make percentage calculations easier.


Percentages are a fundamental part of our daily lives. From calculating taxes to tipping at the restaurant, percentages are used in a variety of situations. In simple terms, percentages are a way of expressing a fraction of an amount in terms of 100. Understanding how to calculate percentages and their real-world applications is an essential skill. In this beginner’s guide, we will explore the basics of percentages, the simple steps to calculate percentages, the foolproof method, mastering percentage calculations, and quick and easy techniques to find percentages in everyday situations.

The Basics of Percentages: A Beginner’s Guide to Figuring Out Percentages

Before we dive into calculating percentages, it’s essential to understand what percentages are and how to convert them into decimals.

A percentage can be defined as a fraction whose denominator is always 100. Percentages are often represented using the ‘%’ symbol. When you see a percentage, it usually refers to a portion of a given quantity. For example, when we say that John scored 80% on his test, it means that he got 80 correct answers out of 100.

Converting decimals to percentages is easy. All you need to do is move the decimal point two places to the right and add the ‘%’ symbol. For example, converting 0.25 to a percentage would be 25%. Conversely, converting percentages to decimals involves moving the decimal point two places to the left. So, 40% would be 0.40 as a decimal.

5 Simple Steps to Calculate Percentages

Calculating percentages is relatively simple if you follow a few essential steps. Here are five easy steps to help you calculate percentages:

Step 1: Read the Problem Carefully

Before you start calculating percentages, read the problem carefully. Understand what is required of you and what information you have. This is critical; otherwise, you might make a mistake that can lead to the wrong answer.

Step 2: Determine the Base

The base is the starting point or a whole quantity. It is usually indicated by the letter ‘B’ or ‘base’. For example, if you want to calculate 30% of 80, 80 is the base.

Step 3: Determine the Percentage

The percentage is the fraction of the base you want to calculate. It is usually indicated by the letter ‘P’ or ‘percentage’. For example, if you want to calculate 30% of 80, 30 is the percentage.

Step 4: Calculate the Percentage

Now that you have the base and the percentage, you can calculate the percentage of the base by multiplying the base by the percentage and dividing the result by 100. The formula is:

P% of B = (P/100) * B

So, if you want to calculate 30% of 80, you can use the formula:

30% of 80 = (30/100) * 80 = 24

Therefore, 30% of 80 is 24.

Step 5: Check Your Work

Always double-check your calculations to ensure that you have the right answer. You can do this by reversing the calculation to find the percentage. For example:

What percentage of 80 is 24?

X% of 80 = 24

X = (24/80) * 100 = 30%

This means that 24 is 30% of 80.

The Foolproof Method for Calculating Percentages

While the above method can work for simple percentage calculations, more complex scenarios might require a different approach. Luckily, there is a formula that you can use to calculate percentages, which works every time.

The formula for calculating percentages is:

P = (A/B) * 100

Where P is the percentage, A is the portion, and B is the total.

Let’s say you’re trying to find out what percentage of your monthly budget you spend on groceries. Your monthly income is $3,000, and your grocery bill for the month is $400. Plugging this information into the formula, we get:

P = (400/3,000) * 100

P = 13.33%

This means that 13.33% of your monthly income goes towards groceries.

Using this formula will give you the right answer every time.

Mastering Percentages: Tips and Tricks to Help You Solve Any Percentage Problem

Now that you know how to calculate percentages let’s take a look at some tips and tricks to help you master percentages.

Understanding the Relationship Between Percentages, Fractions, and Decimals

Understanding the relationship between percentages, decimals, and fractions is essential. A percentage is simply a fraction whose denominator is 100, and a decimal is a fraction whose denominator is a power of 10. Recognizing this relationship can help you convert percentages into decimals and fractions and vice versa.

Applying Percentages in Real-World Situations

Knowing how to apply percentages to real-world scenarios is crucial. From calculating taxes and tips to figuring out discounts and sales, percentages are used in everyday life. Practicing percentage calculations with real-life scenarios can help you improve your calculation skills.

Tips and Tricks for Solving Complex Percentage Problems

Sometimes, percentage problems can be complex, and the basic steps might not be enough. Here are some tips and tricks to help you solve complex percentage problems:

  • Use ratios to compare percentage values
  • Break down big numbers into smaller, easier-to-calculate parts
