Learn how to calculate a percentage increase with a step-by-step guide, examples, infographic, video tutorial, comparison chart, and practice exercises.

## Introduction

Understanding how to calculate a percentage increase is an essential skill for anyone who needs to work with numbers, from students to financial analysts. Knowing how to calculate a percentage increase is important for analyzing data and making informed decisions. This article will provide you with a comprehensive guide to calculating percentage increase, including real-life examples, an infographic, and a video tutorial.

## Step-by-Step Guide

The first step in calculating a percentage increase is to know what percentage increase means. A percentage increase measures the increase in a value as a percentage of the original value. To calculate a percentage increase, follow these simple steps:

1. Subtract the original value from the new value.
2. Divide the result by the original value.
3. Multiply the answer by 100 to get the percentage increase.

For example, if you bought a stock for \$100 and sold it for \$120, the percentage increase would be:

1. \$120 – \$100 = \$20
2. \$20 รท \$100 = 0.2
3. 0.2 x 100 = 20%

So the percentage increase would be 20%.

It’s important to note that the order of the subtraction matters. If you subtract the new value from the original value, the result will be negative. You always want to subtract the original value from the new value to get a positive result.

It’s also important to use the correct formula when calculating percentage increase. Using the wrong formula can result in miscalculations and inaccurate analysis.

## Real-Life Examples

Percentage increase calculations are useful in a variety of real-world scenarios. Here are a few examples:

• Salary Increase: If your salary increased from \$40,000 to \$45,000, what is the percentage increase?
• Sales Increase: A company’s sales went from \$100,000 to \$150,000. What is the percentage increase?
• Population Increase: A city’s population increased from 50,000 to 75,000. What is the percentage increase?

To calculate the percentage increase for each of these scenarios, follow the step-by-step guide. The percentage increase for the salary increase would be 12.5%, the percentage increase for the sales increase would be 50%, and the percentage increase for the population increase would be 50%.

These examples illustrate how percentage increase calculations can be useful in a variety of situations, from personal finance to business analytics.
