What Is Percentage of Change

Percentage change is important because it provides a standardized way to compare changes in different quantities, helping to determine the rate of change and understand trends over time. It allows for easy comparison between different variables and helps in making informed decisions based on the changes observed.

Examples of situations where percentage change is commonly used include:

1. Price changes: Percentage change is often used in finance and economics to measure changes in stock prices, inflation rates, currency exchange rates, and consumer price indexes.

2. Population growth: Demographers use percentage change to track population growth rates in different regions and countries over time.

3. Business performance: Companies use percentage change to analyze changes in sales, profits, market share, and other key performance indicators.

4. Interest rates: Percentage change is used to calculate changes in interest rates for loans, mortgages, and savings accounts.

5. Employment rates: Economists use percentage change to measure changes in unemployment rates and workforce participation.

Calculating Percentage Change

Percentage change = (New Value - Old Value) / Old Value * 100

Here are some practice problems to demonstrate how to calculate percentage change:

Example 1

1. If an item was originally priced at $50 and is now priced at $70, what is the percentage change?

New Value = $70
Old Value = $50

Percentage change = ($70 - $50) / $50 * 100
Percentage change = $20 / $50 * 100
Percentage change = 0.4 * 100
Percentage change = 40%

So, the percentage change is 40%.

Example 2

2. If a population increased from 5000 to 6000, what is the percentage change?

New Value = 6000
Old Value = 5000

Percentage change = (6000 - 5000) / 5000 * 100
Percentage change = 1000 / 5000 * 100
Percentage change = 0.2 * 100
Percentage change = 20%

So, the percentage change is 20%.

Example 3

3. If the temperature increased from 70 degrees to 80 degrees, what is the percentage change?

New Value = 80
Old Value = 70

Percentage change = (80 - 70) / 70 * 100
Percentage change = 10 / 70 * 100
Percentage change = 0.1429 * 100
Percentage change = 14.29%

So, the percentage change is 14.29%.
