## What is a percentage calculator: Why and how to use it?

A percentage calculator is a tool used to perform calculations involving percentages. A percentage is a way of expressing a number as a fraction of 100. It is commonly used in mathematics, finance, and statistics to express a proportion or a change.

### How to use:

• Input the numbers you want to calculate the percentage of or the percentage change for
• Select whether you want to calculate percentage difference, percentage change, or percentage of a number
• Press the calculate button or enter key
• Review the result
• Repeat the process as needed

## Several formulas are commonly used in percentage calculations:

### Percentage of a number:

(part/whole) x 100 = percentage
Example: What is 20% of 100? (20/100) x 100 = 20

### Percentage increase:

(new value – old value)/old value x 100 = percentage increase
Example: What is the percentage increase from \$50 to \$60? (60-50)/50 x 100 = 20%

### Percentage decrease:

(old value – new value)/old value x 100 = percentage decrease
Example: What is the percentage decrease from \$60 to \$50? (60-50)/60 x 100 = 16.67%

### Percentage difference:

(|new value – old value|)/((new value + old value)/2) x 100 = percentage difference
Example: What is the percentage difference between 80 and 100? |100-80|/((100+80)/2) x 100 = 20%

### Percentage change:

(new value – old value)/old value x 100 = percentage change
Example: What is the percentage change from 50 to 60? (60-50)/50 x 100 = 20%

## In conclusion,

A percentage calculator helps calculate percentages, such as percentage difference, percentage change, and percentage increase or decrease. It is widely used in various fields and is essential for making decisions and analyzing data.
