Introduction
Hey readers! In this comprehensive guide, we’ll delve into the world of percentage increases. We’ll empower you with the knowledge and skills to effortlessly calculate percentage increases in various contexts. So, buckle up and get ready to master this fundamental concept!
Understanding Percentage Increases
A percentage increase represents the change in a value relative to its original value, expressed as a percentage. It’s a common way to quantify growth, improvement, or change in various fields.
Calculating Percentage of Increase
Basic Formula
The basic formula for calculating percentage increase is:
Percentage Increase = (New Value – Original Value) / Original Value * 100
Example
Let’s say you invest $1,000 in a stock, and its value increases to $1,200. To calculate the percentage increase:
(1,200 – 1,000) / 1,000 * 100 = 20%
Fractional Increases
Sometimes, you may encounter increases expressed as fractions. To convert a fraction to a percentage increase, simply multiply it by 100.
Example
If an increase is given as 1/4, multiply it by 100:
(1/4) * 100 = 25%
