To find out the percentage of marks, students can simply divide the marks obtained by the maximum marks and then multiply it by 100. Test marks to percentage calculators help students avoid the agony of dealing with how they can convert their grade marks into percentages. Percentage of marks means a fraction or proportion out of 100, which is widely used for academic institutions to evaluate students on a fairly basis. Calculating percentages not only helps students to check their performance but also helps universities and colleges abroad to assess international students on the same scale. We have mentioned a comprehensive guide on how to do percentage calculations easily in this article. The formula to calculate the percentage from marks is (Marks scored ÷ Maximum Marks)×100. For instance, a student achieved 360 marks out of 500. First, divide 360 by 500 and then multiply the result by 100. Here, the percentage of marks is 72%. Hence, it is important for students to calculate the percentage of marks obtained by them for both academic and career purposes. Simply, the percentage of marks obtained meaning is presenting the raw scores of a student in percent averages using a certain formula.

How to Calculate Percentage Change?

In an academic context, the calculation of percentage change is used to determine the change in percentage (increase or decrease) from the previous year's average marks in simple words. It is useful to derive a change in the percentage of the raw quantities over a while. For example, an increase or decrease in a student’s marks from the previous year of studies grading.

The formula for calculating Percentage Change = (Change in Value/Original Value)*100

Here, change in value = New Value-Original Value

Percentage of Change Formula:

There are two types to calculate the percentage of marks that are either increasing or decreasing.

Calculate Percentage Increase

An increased change in the percentage of marks meaning is an increase in the value of grades over time. The formula used to determine the percentage increase can be derived by following the steps below:

  • Find out the increase in value= Increased value-Original Value

  • Percentage increase = (Increase in value/original value)*100

Example:

A student scored 20 marks in Test 1 and 30 marks in Test 2. Find out the percentage of increase.

Here,

Original Value = 20 (Marks of Test 1)

Increased Value = 30 (Marks of Test 2)

Change in Percentage of Marks = Increased value-Original Value = 30-20 = 10

Percentage of Increase = (10/20)*100 %

= 50%

Calculate Percentage Decrease

The decreased percentage of marks denotes the reduction of value from the previous one over the course of time. The formula used to determine the percentage decrease can be derived by following the steps below:

  • Find out the decrease in value = Original Value-Decreased value

  • Percentage decrease = (Decrease in value/original value)*100

Example:

A student scored 95 in Test 1 and 89 marks in Test 2. Find out the percentage of decrease.

Here,

Original Value = 95 (Marks of Test 1)

Decreased Value = 89 (Marks of Test 2)

Change in Percentage of Marks = Original Value-Decreased Value = 95-89 = 6

Percentage of Decrease = (06/95)*100 %

= 6.3%

Note: The percentage of marks calculator that are available online do not provide the steps for percentage increase or decrease.

Here,

  • Percentage obtained = 96%

  • Total Marks=500 (5 subjects of 100 maximum marks each)

  • Marks of Percentage = (Percentage/100)*total marks

  • =(96/100)*500

  • 0.96*500

  • 480 marks.

Hence, a student achieved 480 marks out of 500 in his 5 subjects.
