How to Calculate Percentage of Marks?

Many students ask how to calculate percentage of marks when applying for higher education abroad, scholarships, or university admissions. The percentage of marks can be calculated using a simple formula:

Percentage = (Marks Obtained ÷ Total Marks) × 100

This formula helps students calculate their percentage even when the total marks are not 100. Understanding how to calculate percentage of marks is important for evaluating academic performance and preparing transcripts for study abroad applications. In this guide, you will learn the calculation method with clear examples and useful tips.

In simple terms, a percentage represents a value out of 100 and helps measure academic performance. For students planning to study abroad, calculating the percentage of marks is often required when converting grades for university admissions or scholarship applications. 

While the formula makes the calculation straightforward, students can also use an online marks percentage calculator to quickly determine their score. The Study abroad calculator tools below help you calculate your percentage easily by entering your obtained marks and the total marks.

How to Calculate Percentage of Marks?

To calculate the percentage of marks, you only need a simple arithmetic formula. Divide the marks obtained by the total marks and then multiply the result by 100.

Formula:

Percentage = (Marks Obtained ÷ Total Marks) × 100

This marks to percentage formula works for both a single subject and multiple subjects.

If you are calculating the percentage for a single subject, divide the marks obtained by the maximum marks and multiply the result by 100.

If there are multiple subjects, first add all the marks obtained and then divide the total by the maximum total marks. Finally, multiply the result by 100 to get the percentage of marks.

You can perform this calculation manually using the formula above or quickly determine your result using the marks percentage calculator provided above.

Examples on how to calculate the percentage of marks

The calculation process becomes clearer when applied to real examples. The following examples show how the percentage of marks is calculated using the formula in different situations.

Example 1

How to calculate the percentage of marks of 7 subjects? Here's how - Maths 92, Physics 88, Chemistry 76, Hindi 72, Biology 83, Computer science 85, Social Science 77.

Solution:

Total marks scored - 92+88+76+72+83+85+77 = 573
Maximum marks = 700
Percentage of marks - (573/700)x100 = 81.85%

Example 2

How to calculate the percentage of marks of 6 subjects? Here's how - Maths 85, Science 90, Language 80, Biology 90, Computer Science 95, Social Science 85.

Solution:

Total grade score = 525
Maximum marks = 600
Percentage of marks - (525/600)x100 = 87.5%

Example 3

How to calculate the percentage of marks of 5 subjects? Here's how - Maths 100, Science 95, Language 90, Biology 95, History 90

Solution:

Total grade score = 470
Maximum marks = 500
Percentage of marks - (470/500)x100 = 94%

After referring to the examples, try different scenarios in calculating the percentage of marks, including calculating percentage increase, percentage decrease and the percentage of a number.

How to Calculate Percentage Increase?

Percentage increase shows how much a value has increased compared to the original value.

Formula

Percentage Increase = ((Final Value − Initial Value) ÷ Initial Value) × 100

Example

A student’s score increased from 70 marks to 84 marks.

Increase in marks = 84 − 70 = 14

Percentage Increase = (14 ÷ 70) × 100
Percentage Increase = 20%

How to Calculate the Percentage Decrease?

Percentage decrease shows how much a value has reduced compared to the original value.

Formula

Percentage Decrease = ((Initial Value − Final Value) ÷ Initial Value) × 100

Example

A student’s score decreased from 90 marks to 72 marks.

Decrease in marks = 90 − 72 = 18

Percentage Decrease = (18 ÷ 90) × 100
Percentage Decrease = 20%

How to Calculate Percentage of a Number?

To calculate the percentage of a number, you can convert the value into a decimal and then multiply it by 100.

Method 1: Fraction Form 

If the number is in fraction form, first convert it into a decimal and then multiply the result by 100.

Example

46 ÷ 50 = 0.92
0.92 × 100 = 92%

Method 2: Decimal Form

If the number is already in decimal form, simply multiply it by 100 to convert it into a percentage.

Example

0.863 × 100 = 86.3%
