Marks to Percentage Calculator

What Is the Formula to Calculate Percentage from Marks?

The formula is: Percentage = (Marks Obtained ÷ Maximum Marks) × 100. If you scored 450 out of 600, your percentage is (450 ÷ 600) × 100 = 75%. This formula works for any exam, any board, any number of subjects. The only inputs you need are the marks you got and the total marks available.

That's genuinely all there is to it. No university-specific multipliers, no weighted adjustments. Marks percentage is a straightforward ratio. Unlike CGPA to percentage conversion, which varies by university, marks percentage always follows the same formula.

Here are three worked examples:

How to Calculate Percentage of Marks: Step by Step

You don't need a calculator for this. But having one speeds things up when you have six subjects.

Step 1: Write down your marks obtained.
This is the number on your marksheet. For example, 72 in Mathematics.

Step 2: Write down the maximum marks for that subject.
For most Indian school exams, this is 100. For some, it's 80 or 50.

Step 3: Divide marks obtained by maximum marks.
72 ÷ 100 = 0.72

Step 4: Multiply by 100.
0.72 × 100 = 72%

That's your subject percentage. If you want an overall percentage across subjects, you add all marks together before dividing. See the next section for that.

One mistake students often make: they average the subject percentages instead of adding the raw marks. That gives you the wrong answer unless every subject has the same maximum. The correct method always uses totals.

How Do You Calculate Percentage for Multiple Subjects?

Add all your marks obtained across every subject. Then add all the maximum marks. Apply the formula once to those totals: (Total Obtained ÷ Total Maximum) × 100. Do not average your individual subject percentages first; that gives the wrong result if subjects have different maximum marks.

Here's a worked example with 5 subjects of different maximums:

Overall percentage: (250 ÷ 360) × 100 = 69.4%

If you had averaged the five individual subject percentages instead, you'd get 68.8%. Close, but not the same. For board exam applications and scholarship forms, always use the correct method shown above.

The calculator's Subject-wise tab at the top does this automatically. Enter up to 8 subjects, each with its own maximum, and it handles the totals for you.

Pass Marks Reference Table

Students searching for pass marks need one clear answer, not a calculation. Here it is.

CBSE requires a minimum of 33% in each subject for Class 10 and 12, including both theory and practical components separately. Most state boards use either 33% or 35% depending on the board's rules.

Note: Passing marks vary by board and sometimes by subject. CBSE uses 33%. Karnataka SSLC uses 35%. Some competitive exams have their own cutoffs. Always check your board's official notification.

How Is CBSE Percentage Calculated for Class 10 and 12?

CBSE does not give an overall percentage score on the Class 10 marksheet. It gives a CGPA (Cumulative Grade Point Average) based on five main subjects. To get the percentage equivalent, multiply that CGPA by 9.5. For Class 12, marks are displayed directly on the marksheet, and you calculate percentage normally using the formula (Total Obtained ÷ Total Maximum) × 100.

Here's how each class works in practice.

Class 10

CBSE Class 10 uses a 9-point grading scale. The CGPA is the average of grade points earned across five main subjects. Multiplying that CGPA by 9.5 gives the percentage equivalent.

So if your CBSE Class 10 CGPA is 9.2:
Percentage = 9.2 × 9.5 = 87.4%

Class 12

Class 12 marksheets show actual subject marks. Most subjects have 80 marks for theory and 20 marks for practicals, totalling 100 per subject across five subjects (maximum 500). Your percentage is:

Percentage = (Total Marks Obtained ÷ 500) × 100

In the 2025 board exams, 93.66% of over 23 lakh students cleared the CBSE Class 10 examination. That's a massive cohort. A lot of those students will be calculating this exact number for Plus One admissions.

How Is SSLC Percentage Calculated in Kerala?

For Kerala SSLC, your marksheet shows grades rather than raw marks. To calculate your percentage from those grades, multiply your Total Grade Points (TGP) by 1.11. TGP is the sum of all your grade points across subjects. So if your TGP is 70, your percentage is 70 × 1.11 = 77.7%. If you have raw marks from Pareeksha Bhavan, use (Total Marks ÷ 640) × 100 instead.

Kerala uses a nine-point grading scale. The Kerala SSLC total marks across all subjects is 640, with each subject divided into theory and practical components. Students need a minimum D+ grade (30%) in each subject to pass.

Kerala SSLC Grade Points

Worked example: If your grades are A+, A, B+, A, B+, A, A+, A, B, A your TGP = 9+8+7+8+7+8+9+8+6+8 = 78. Percentage = 78 × 1.11 = 86.6%.

Note: This is an estimated percentage based on grade midpoints. For exact percentage figures, students can request their actual marks from Kerala Pareeksha Bhavan, as the official marksheet only shows grade points.

Percentage to Grade: What Does Your Score Actually Mean?

Once you have your percentage, you'll want to know what it means for admissions, scholarships, and jobs.

Most Indian government job notifications set 50% or 60% as the minimum academic qualification. If you're aiming for postgraduate admission abroad, you'll also need to convert this to a GPA. The CGPA to GPA calculator handles that conversion for US and international applications.

If your percentage isn't where you want it, the SGPA to CGPA calculator can help you track your semester performance and see how much you can realistically improve your overall score.

Frequently Asked Questions

What is the formula to calculate percentage from marks?

Percentage = (Marks Obtained ÷ Maximum Marks) × 100. For example: 450 marks out of 600 equals (450 ÷ 600) × 100 = 75%. This formula works for single subjects, multiple subjects combined, and any exam board.

What are the passing marks out of 70?

At 33%, you need 23 marks out of 70. At 35%, you need 25 marks. CBSE uses the 33% rule. Check your specific board's notification to confirm which percentage applies to your exam.

What are the passing marks out of 80?

At 33%, you need 27 marks out of 80. At 35%, you need 28 marks. For CBSE subjects with 80-mark theory papers, the minimum is 27 marks.

How do I calculate CBSE Class 10 percentage?

CBSE Class 10 gives a CGPA, not a direct percentage. Multiply your CGPA by 9.5 to get the percentage equivalent. If your CGPA is 8.4, your percentage is 8.4 × 9.5 = 79.8%.

Can I calculate percentage for 6 or 7 subjects?

Yes. Add all your obtained marks across every subject. Add all the maximum marks. Then apply: (Total Obtained ÷ Total Maximum) × 100. The Subject-wise tab in the calculator at the top of this page handles up to 8 subjects.

What percentage is considered First Class?

60% and above is First Class at most Indian universities and school boards. 75% and above is usually Distinction or First Class with Distinction.

How do I convert my percentage to CGPA?

Divide your percentage by 9.5 for the standard AICTE formula. So 76% becomes 8.0 CGPA. Use the percentage to CGPA calculator for university-specific formulas including VTU, Mumbai University, and Anna University.

What is 500 out of 600 as a percentage?

(500 ÷ 600) × 100 = 83.3%. This applies to any exam where the total is 600, including SSLC Karnataka and some Class 12 setups.

How is SSLC percentage calculated in Kerala?

Multiply your Total Grade Points (TGP) by 1.11. TGP is the sum of grade points across all subjects. If your TGP is 72, your percentage is 72 × 1.11 = 79.9%. For exact figures, request your actual marks from Kerala Pareeksha Bhavan.
