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,
