How to Use
  1. Pick the direction: CGPA → % or % → CGPA.
  2. Choose the board or university whose rule applies to your grade card, such as CBSE, VTU (by scheme), University of Mumbai, Anna University or JNTU Hyderabad.
  3. If yours is not listed, choose My own rule and type the multiplier and offset from your university’s regulations (percentage = multiplier × CGPA + offset).
  4. Type your CGPA, for example 8.4, or the percentage, for example 85.
  5. Read the result and the working, and compare the same CGPA under every published rule in the table below the chart.
Input
Percentage = multiplier × CGPA + offset. Copy the numbers from your university’s regulations: (CGPA − 0.5) × 10 is multiplier 10, offset −5.

Worked Example

CBSE. A CGPA of 8.4 on a CBSE grade sheet: 9.5 × 8.4 = 79.8%. CBSE calls this the “indicative percentage of marks”.

University of Mumbai. The same 8.4 under Mumbai’s CBCS rule: 7.1 × 8.4 + 11 = 70.64, which the circular says to round up to the next full integer: 71%. Same CGPA, nine percentage points apart.

The common mistake: using ×9.5 everywhere. A VTU student on the 2022 scheme with a CGPA of 8.2 who multiplies by 9.5 writes 77.9%. VTU’s 2022 regulations say CGPA × 10, and use exactly this example: 8.20 × 10 = 82.0%. On VTU’s 2015–2018 schemes the same 8.2 would be (8.2 − 0.75) × 10 = 74.5%.

Backwards. To show 85% under CBSE’s rule you need 85 ÷ 9.5 = 8.95.

Formulas

CBSE
% = 9.5 × CGPA
8.4 → 79.8%; a 10 gives 95%
University of Mumbai (CBCS)
% = 7.1 × CGPA + 11, rounded up
8.4 → 70.64 → 71%; a 10 gives 82%
VTU 2022 · Anna University R-2021
% = CGPA × 10
8.2 → 82%
VTU 2015, 2017, 2018 schemes
% = (CGPA − 0.75) × 10
7.5 → 67.5%; a 10 gives 92.5%
JNTU Hyderabad R22 · R25
% = (CGPA − 0.5) × 10
8.0 → 75%; a 10 gives 95%
Percentage back to CGPA
CGPA = (% − offset) ÷ multiplier
CBSE: 85 ÷ 9.5 = 8.95

Why Every Board Has Its Own Formula

A CGPA is a credit-weighted average of grade points, and each grade point stands for a band of marks. CBSE’s Class X scheme, for example, gives grade point 10 for 91–100 marks, 9 for 81–90 and so on down to 4 for 33–40. Once marks are turned into bands the exact percentage is gone, so any way back is an approximation. The University of Mumbai says so in its circular: the CGPA “cannot be directly related to the actual percentage of marks scientifically. The conversion formula is approximate representation of CGPA to percentage.”

That is why each board or university publishes its own rule, and why a rule belongs to one scheme: VTU changed from (CGPA − 0.75) × 10 for its 2015–2018 schemes to CGPA × 10 in its 2022 regulations. If your grade card or your university’s regulations print a rule, that rule wins over anything on this page.

Converting to a 4.0 GPA. World Education Services (WES), whose evaluations many US and Canadian universities ask for, does not publish a formula for turning a 10-point CGPA into a 4.0 GPA. It says it evaluates the grades on your transcript and converts them to the US 4.0 scale itself, taking into account how universities in your country grade, and that its free iGPA Calculator gives a reference figure only (WES Advisor Blog). This page therefore has no 10-point to 4.0 rule.

Only rules found in an official, downloadable document from the board or university itself are listed. The University of Mumbai circular is a scanned PDF on mu.ac.in; an archived copy is linked from the data file behind this page.

About This Converter

This converter turns a CGPA into a percentage, or a percentage into the CGPA that gives it, with the formula a board or university has published: CBSE, the University of Mumbai, VTU (2022 and 2015–2018 schemes), Anna University and JNTU Hyderabad, each quoted from its own circular or regulations. For anywhere else, type your university’s multiplier and offset.

Every answer shows the working, a chart of the rule beside the others, and a table of the same CGPA under every published rule, so you can see why two certificates with the same CGPA can show different percentages. Your university’s own rule always wins. Everything runs in your browser and nothing you enter is sent anywhere.

Frequently Asked Questions

How do I convert a CBSE CGPA to a percentage?

Multiply by 9.5. CBSE’s Examination Bye-Laws (Rule 38-A, the Class X grading scheme) give “Overall indicative percentage of marks = 9.5 x CGPA”, and the same 9.5 for each subject’s grade point. A CGPA of 8.4 is 79.8%, and 9.2 is 87.4%.

Can I multiply any CGPA by 9.5?

No. 9.5 is CBSE’s rule. VTU’s 2022 scheme and Anna University’s R-2021 multiply by 10 (8.2 is 82%), VTU’s 2015–2018 schemes use (CGPA − 0.75) × 10, JNTU Hyderabad uses (CGPA − 0.5) × 10, and the University of Mumbai uses 7.1 × CGPA + 11. Your own university’s rule always wins.

How do I convert a percentage back to a CGPA?

Work the same rule backwards. Under CBSE’s rule 85% ÷ 9.5 = 8.95. Under Mumbai’s, (60 − 11) ÷ 7.1 = 6.90, but because Mumbai rounds the percentage up, a CGPA of 6.77 already prints as 60%. The official documents only give the CGPA-to-percentage direction.

How does WES convert an Indian CGPA to a 4.0 GPA?

WES does not publish a CGPA formula. It says it evaluates the grades on your transcript and converts them to the US 4.0 scale itself, using criteria that include how universities in your country grade, and that its free iGPA calculator gives a reference figure only. So this page offers no 10-point to 4.0 formula.

Why is a perfect 10 CGPA 82% in one place and 100% in another?

Each formula is set by its own board or university for its own grading scheme. A 10 is 95% under CBSE’s rule, 92.5% under VTU’s 2015–2018 rule, 100% under VTU 2022 and Anna University, 95% under JNTU Hyderabad and 82% under the University of Mumbai’s rule. Mumbai’s circular calls its formula an approximate representation.

How do I use the CGPA to Percentage Converter?

Just type or paste your value. The answer shows up right away — there is no button to press. Change anything and it updates by itself.

Do I need to install or sign up for anything?
