How to Calculate the Percentage of Marks for 6 Subjects

When school or board exam results are declared, students receive their total marks across 5 or 6 different subjects. However, colleges and universities always ask for your 'Final Percentage' for admission. Here is the exact, simple step-by-step formula to calculate your percentage accurately.

Question (Click to Flip)

What if one subject is out of 50 marks, and the others are out of 100?

Answer

You must adjust the 'Maximum Total Marks'. Five subjects $\times$ 100 = 500. Plus one subject of 50 = 550. So, your formula will be: (Your Total Marks ÷ 550) × 100.

Key Facts

In some CBSE or ICSE board rules, the 'Best of 5' rule applies. Even if you took 6 subjects, you are allowed to drop the subject with the lowest marks and only calculate the percentage based on your top 5 subjects (Total out of 500).

The word 'Percent' literally comes from Latin 'Per Centum', which mathematically translates to 'out of one hundred'.

Step 1: Find Your 'Total Obtained Marks'

Take your report card and mathematically add up the exact marks you scored in all 6 individual subjects.
Example: Let's say you scored 85 in English, 90 in Math, 80 in Science, 88 in History, 92 in Computer, and 75 in Hindi.
Obtained Marks = $85 + 90 + 80 + 88 + 92 + 75 = \textbf{510}$.

Step 2: Find the 'Maximum Total Marks'

Find out the maximum possible marks for each subject. Usually, school exams are out of 100 marks per subject.
Since there are 6 subjects, you multiply: $6 \times 100 = \textbf{600}$.
Maximum Marks = 600.

Step 3: Apply the Magic Percentage Formula

The universal mathematical formula for calculating percentage is: Percentage = (Total Obtained Marks ÷ Maximum Total Marks) × 100

Let's apply it to our example:

Divide 510 by 600: $510 \div 600 = 0.85$
Multiply the result by 100: $0.85 \times 100 = \textbf{85%}$.

The Shortcut Trick (For exams out of 100)

If every single one of your 6 subjects has a maximum mark of exactly 100, there is a massive shortcut.

Just add your total marks and directly divide by 6.
Shortcut Example: $510 \div 6 = \textbf{85%}$.
