Many students get confused about:

• Should practical marks be included?

• Is English compulsory?

• How to calculate the percentage of the best five subjects?

• What if there are six subjects?

In this article, you will get a clear step-by-step method to calculate percentage in CBSE Class 12, including formulas, examples, important rules, and common mistakes to avoid.

What is the Formula to Calculate CBSE Class 12 Percentage?

The basic formula to calculate percentage is:

{Percentage = (Total Marks Obtained ÷ Maximum Marks) × 100}

This formula works for:

• All 5 subjects

• Best of five subjects

• All 6 subjects (if required)

Step-by-Step Process to Calculate CBSE Class 12 Percentage

Step 1: Add Marks of Required Subjects

First, add the marks of the subjects you want to calculate percentage for.

Usually, students calculate percentage of:

• Best 5 subjects, or

• All 5 main subjects

Step 2: Calculate Total Maximum Marks

In CBSE Class 12, most subjects are of 100 marks each.

If calculating for:

• 5 subjects → Maximum marks = 500

• 6 subjects → Maximum marks = 600

Step 3: Apply the Percentage Formula

Use the formula:

Percentage = (Total Marks ÷ Total Maximum Marks) × 100

Example: How to Calculate CBSE Class 12 Percentage

Let’s understand with an example.

Step 1: Add the Marks

92 + 85 + 88 + 90 + 95 = 450

Step 2: Maximum Marks

5 subjects × 100 = 500

Step 3: Apply Formula

(450 ÷ 500) × 100 = 90%

✅ Final Percentage = 90%

Should You Include Practical Marks in CBSE Percentage?

Yes. In CBSE Class 12:

• Practical marks are already included in your final subject marks.

• You do NOT need to calculate theory and practical separately.

• Simply use the final marks mentioned in your marksheet.
