About Percent and Percentage

Calculating the Percentage loss or gain is a crucial concept. Many financial, statistical as well as real-life examples are related to the concept of Percentage loss.

The Formula for Calculating Percentages

A percentage is equal to the actual value divided by the total value multiplied by 100. 

The percentage formula is:

Percentage % = ( \[\frac{Actual \; Value}{Total \; Value}\] ) x 100 

Some other important formulas for percentage change are as follows.

• Percentage change formula

1. Percent Increase

2. Percent Decrease

• Percentage error formula

The formula of Percentage Change

Percent Change =  \[\frac{New \; Value \; - \; Actual \; Value}{Actual \; Value}\] x 100 

There are two different types of percentage change. They are

• Percentage Increase

• Percentage Decrease

Percentage Increase Formula

The percentage increase formula is the increased value divided by the original value that is further multiplied by 100. It is expressed in terms of percentage. If a value is increased, then there is an increase in percentage.

Thus to Calculate the Percentage Increase We Have to Follow Two Steps

Step-1: Calculate the difference i.e. increase between the two numbers.

i.e. Increase = New Number - Original Number

Step-2: Divide the increased value by the original number and further multiply the answer by 100.

Formula to calculate the percentage increase

Percentage increase = \[\frac{Increase}{Original \; Value}\]x 100

Percentage Decrease Formula

The percentage decrease formula is the decreased value divided by the original value and further multiplied by 100. It is expressed in terms of percentage. If there is a decrease in the value, then there is a decrease in percentage.

Thus to Calculate the Percentage Decrease We Will Follow Two Steps

Step-1: Calculate the difference i.e. decrease between the two numbers.

i.e. decrease = New Number - Original Number

Step-2: Divide the decrease in value by the original value and multiply the answer by 100.

Percentage Decrease =  \[\frac{Decrease}{Original \; Value}\]x 100
