Indian schools and universities report results as a CGPA, but scholarship forms, job portals and some universities abroad ask for a percentage. There is no single national formula. CBSE uses one multiplier, and each university sets its own rule. This guide gives the CBSE method, the formulas published by major universities, a quick conversion table, and what universities abroad actually want, checked on 28 October 2026.
- CBSE's indicative formula is percentage equals CGPA multiplied by 9.5
- VTU uses (CGPA minus 0.75) multiplied by 10 for its 2015, 2017 and 2018 schemes, and GTU uses (CGPA minus 0.5) multiplied by 10
- A 2023 KTU order changed its 2019-scheme formula from 10 times CGPA minus 2.5 to CGPA multiplied by 10
- Always use your own university's formula.
How Do You Convert CGPA to Percentage?
For CBSE, multiply your CGPA by 9.5. A CGPA of 8.4 gives 8.4 times 9.5, which equals 79.8 percent. For a university degree, use the formula your university publishes, because many use a different rule. VTU, GTU, KTU and Anna University each have their own formula, shown later in this guide.
The 9.5 multiplier belongs to CBSE's old Class 10 grading scheme. It is not a universal rule, so do not apply it to an engineering or degree CGPA unless your university says so. If an application asks for a percentage and your university has no official formula, give your CGPA, the grading scale and a note that no official conversion exists.
| CBSE CGPA 2026 | Percentage (CGPA x 9.5) |
|---|---|
| 10 | 95 |
| 9.5 | 90.25 |
| 9 | 85.5 |
| 8.5 | 80.75 |
| 8 | 76 |
| 7.5 | 71.25 |
| 7 | 66.5 |
| 6.5 | 61.75 |
| 6 | 57 |
| 5 | 47.5 |
Why Does CBSE Use 9.5 to Convert CGPA?
CBSE looked at five years of results and found that students in the top 91 to 100 marks band averaged about 95 marks. Because that band equals a grade point of 10, CBSE divided 95 by 10 and got 9.5. Multiplying any CGPA by 9.5 therefore gives an indicative, not exact, percentage of marks.
CBSE used CGPA for Class 10 under the Continuous and Comprehensive Evaluation scheme from about 2010, and returned to marks and percentages from the 2017-18 board exams. If you passed Class 10 in those years, your marksheet shows a CGPA, and the 9.5 formula is the accepted way to state a percentage.
| CBSE grade 2026 | Marks range | Grade point |
|---|---|---|
| A1 | 91 to 100 | 10 |
| A2 | 81 to 90 | 9 |
| B1 | 71 to 80 | 8 |
| B2 | 61 to 70 | 7 |
| C1 | 51 to 60 | 6 |
| C2 | 41 to 50 | 5 |
| D | 33 to 40 | 4 |
How Do You Calculate CGPA Step by Step?
Add the grade points of your five main subjects and divide by five. For grade points of 9, 10, 8, 7 and 8, the total is 42, and 42 divided by 5 gives a CGPA of 8.4. For a CBSE percentage, multiply 8.4 by 9.5 to get 79.8 percent. Leave out the additional sixth subject.
University CGPA works differently because subjects carry credits. Multiply each course's grade point by its credits, add the results, and divide by the total credits. For example, a 4-credit course with grade point 9 and a 3-credit course with grade point 8 give (36 plus 24) divided by 7, which is about 8.57.
Which Formula Do Indian Universities Use?
Each university publishes its own rule. VTU uses (CGPA minus 0.75) times 10 for its 2015, 2017 and 2018 schemes. GTU uses (CGPA minus 0.5) times 10. KTU switched to CGPA times 10 in 2023. Anna University is widely reported to certify CGPA times 10. Check your marksheet or university for the official version.
| University 2026 | Formula | Example for CGPA 8 |
|---|---|---|
| CBSE (Class 10) | CGPA x 9.5 | 76% |
| VTU (2015, 2017, 2018 schemes) | (CGPA - 0.75) x 10 | 72.5% |
| GTU | (CGPA - 0.5) x 10 | 75% |
| KTU (2019 scheme, from 2023) | CGPA x 10 | 80% |
| Anna University | CGPA x 10 (widely reported) | 80% |
| Mumbai University (10-point, engineering) | 7.1 x CGPA + 11 (older circular) | 67.8% |
| MAKAUT | Official table; often summarised as (DGPA - 0.75) x 10 | 72.5% |
Formulas change with new regulations, and the same university can use different rules for different schemes. VTU's newer schemes, for example, may not use the 0.75 deduction. MAKAUT publishes a conversion table rather than a simple formula, and calculator sites summarise it in different ways. Ask your examination section for a conversion certificate if a university or employer needs an official figure.
How to Convert GPA to PercentageRead →Do Universities Abroad Accept Your CGPA to Percentage Conversion?
Most universities abroad assess your original CGPA and grading scale, not a percentage you calculate yourself. UK universities list Indian entry requirements as a CGPA or percentage band, and many US universities ask for a credential evaluation such as WES. Give the figures on your transcript and attach your university's official conversion if one exists.
Never invent a conversion to look stronger. Admissions teams see thousands of Indian transcripts and know each university's scale. If your CGPA is just below a requirement, contact the admissions office with your transcript, because many accept a slightly lower score with strong work experience, test scores or a good final-year record.
How to Get a Scholarship to Study Abroad for Indian StudentsRead →How Do You Convert SGPA to CGPA?
SGPA is your grade point average for one semester, and CGPA is the credit-weighted average of all semesters. Multiply each semester's SGPA by its total credits, add the results, and divide by the total credits for all semesters. If every semester has the same credits, you can simply average the SGPAs.
For example, if semester one has an SGPA of 8.2 over 24 credits and semester two has 8.8 over 26 credits, the CGPA is (196.8 plus 228.8) divided by 50, which is about 8.51. Most universities print both SGPA and CGPA on the marksheet, so use the printed CGPA where available.
What Is a CGPA to Percentage Conversion Certificate?
It is an official letter or certificate from your board or university stating the percentage equivalent of your CGPA, using its own approved formula. Universities abroad, employers and scholarship bodies may ask for it when your marksheet shows only a CGPA. Request it from your university's examination section or controller of examinations.
CBSE students can show the 9.5 formula printed on the CCE-era marksheet. For degrees, the certificate carries much more weight than an online calculator. Ask for it in good time, because processing can take a few weeks, and order extra sealed copies if you will apply to several universities.
What Mistakes Should You Avoid When Converting CGPA?
The most common mistakes are using CBSE's 9.5 multiplier for a university degree, mixing up SGPA and CGPA, averaging semesters without weighting by credits, and rounding up to meet a cut-off. Admissions teams check transcripts, so always use your university's formula and report the exact figure printed on your marksheet.
Also check whether the application asks for your CGPA out of 10, out of 4, or as a percentage, and answer in exactly that format. If an online form forces a 4.0 scale, add a note that your university uses a 10-point scale, and upload your official transcript so the admissions team can assess it correctly.
How Do You Convert Percentage to CGPA?
Reverse the formula your board or university uses. For CBSE, divide the percentage by 9.5, so 85 percent becomes about 8.9 CGPA. For VTU, divide by 10 and add 0.75. For GTU, divide by 10 and add 0.5. For universities that use CGPA times 10, simply divide the percentage by 10.
Use reverse conversions only for rough comparisons, for example to check whether you meet a scholarship cut-off. When you fill in an official form, enter the figure printed on your marksheet and the scale it uses, such as 8.2 out of 10, rather than a number you converted yourself.
