CGPA to Percentage: Which Formula to Use (Free)

There's no single CGPA to percentage formula. CBSE's old Class 10 grading gave an indicative percentage of CGPA × 9.5, so 8.4 became 79.8%. Universities set their own rules, and the same 8.4 can come out anywhere from about 76% to 84% depending on the formula. Use the one your own university publishes, usually on the marksheet, transcript or in its exam regulations. The free percentage calculator handles the arithmetic once you know which formula applies.

CBSE: multiply by 9.5

When CBSE graded Class 10 students on a 10-point CGPA (under its CCE scheme, roughly the 2010 to 2017 board results), its marksheets stated that the indicative percentage of marks could be worked out as 9.5 × CGPA, subject by subject or overall. The 9.5 is usually explained as the average mark of students in the top band (A1, 91-100 marks, about 95) divided by that band's grade point of 10. The marksheet called the result indicative, not exact. If you need an official figure for an old CBSE result, check the note on your own marksheet or CBSE's circulars for that year.

CBSE CGPA	× 9.5
9.2	87.4%
8.4	79.8%
7.4	70.3%
6.5	61.75%

This rule was for CBSE's CGPA only. It isn't a general formula for college CGPAs, though it often gets used that way.

Universities: each sets its own CGPA to percentage rule

Engineering and other universities across India, such as VTU, SPPU (Pune), the University of Mumbai and AKTU, each define how their CGPA or SGPA converts to a percentage. Some formulas you'll see quoted for different institutions:

• CGPA × 10
• (CGPA − 0.75) × 10
• (CGPA − 0.5) × 10
• CGPA × 9.5
• A table or slabs, with a different rule for different CGPA ranges

Here's how much the choice matters for the same CGPA:

CGPA	× 9.5	× 10	(CGPA − 0.75) × 10	(CGPA − 0.5) × 10
9.2	87.4%	92%	84.5%	87%
8.4	79.8%	84%	76.5%	79%
7.4	70.3%	74%	66.5%	69%
6.5	61.75%	65%	57.5%	60%

A gap of 7-8 percentage points can decide whether you meet a "60% or above" job or admission cut-off. So don't pick the formula that gives the best number, and don't trust a formula from a random website or group chat. Universities also revise their schemes between batches, so even a formula a senior used may not apply to you.

How to find your university's formula

Check these, in roughly this order:

1. The back of your marksheet or grade card. Many universities print the conversion rule there.
2. Your transcript. Some transcripts state the equivalent percentage directly.
3. The university's exam regulations or ordinance for your course and batch year, usually on its website under examinations or academics.
4. The exam section or your college office. Ask in writing which formula applies to your batch.
5. A conversion certificate. Many universities issue an official letter stating your equivalent percentage. Employers and foreign universities often accept this more readily than a figure you calculate yourself.

Keep a copy of whichever source you use, so you can show where your percentage came from if anyone asks.

How to convert with the calculator

Once you know the formula, the free percentage calculator does the sums:

• For CGPA × 10: use X is what percent of Y? Type 8.4 and 10. Answer: 84%.
• For CGPA × 9.5: use What is X% of Y? Type 950 and 8.4. Since 950% of a number is 9.5 times it, the answer is 79.8.
• For (CGPA − 0.75) × 10: subtract first (8.4 − 0.75 = 7.65), then use What is X% of Y? with 1000 and 7.65. Answer: 76.5.

If your marksheet shows actual marks rather than grade points, skip CGPA altogether: add your marks, divide by the maximum and multiply by 100. Our guide to calculating percentage of marks walks through it with subject tables.

CGPA vs SGPA

Your SGPA is the grade point average for one semester; your CGPA is the cumulative average across all semesters so far, usually weighted by credits. Most conversion rules apply to the final CGPA, not to a single SGPA. Our guide to SGPA vs CGPA shows how one is built from the other.

Converting for jobs, exams and study abroad

• Indian job applications and government exams often ask for a percentage. Use your university's formula and keep the proof; some notifications state their own rule for converting CGPA, which then takes priority.
• Postgraduate admissions may set a CGPA cut-off directly, so check whether a conversion is needed at all.
• Study abroad: foreign universities and credential evaluators often convert your grades using their own method, sometimes onto a 4-point GPA. Send your official transcript and any conversion certificate, and let them convert; don't send a figure you calculated yourself as if it were official.
