How to use the CGPA to Percentage Calculator
- Enter your CGPA out of 10, for example 8.4.
- Read the percentage. It updates instantly.
- Check whether the institution or employer you are applying to accepts the CBSE method or asks for its own formula.
Formula used
Percentage = CGPA × 9.5 (CBSE method for a 10-point scale).
Worked example
Here is the CGPA to Percentage Calculator worked through with the example values shown above, so you can check each step by hand.
| Inputs | |
|---|---|
| CGPA (out of 10) | 8.4 |
| Result | |
| Percentage | 79.8% |
The CBSE formula with examples
Percentage = CGPA × 9.5. A CGPA of 8.4 gives 8.4 × 9.5 = 79.8%. A CGPA of 7.2 gives 68.4%, and a CGPA of 9.1 gives 86.45%. CBSE has stated that the overall percentage can be approximated by multiplying the CGPA by 9.5.
To convert the other way, divide the percentage by 9.5. For 79.8%, 79.8 ÷ 9.5 = 8.4.
Why the factor is not the same everywhere
The ×9.5 factor comes from how CBSE grade points relate to marks. Universities and boards grade differently, so some use ×10, some use their own tables or a different formula, and some ask you to submit an official conversion certificate from your university. A conversion that is correct for one board can be wrong for another.
If a form asks for percentage and you have a CGPA, look for instructions on the form or the institution’s website. When in doubt, ask your university for an official statement of the equivalent percentage and attach it with your application.
CGPA, SGPA and percentage
SGPA is your grade point average for a single semester, and CGPA is the cumulative average across all semesters. Convert your final CGPA, not one semester’s SGPA, when a form asks for your overall percentage. Some applications ask for the percentage of the last two years or particular subjects, so read the question carefully.
Other conversion methods you may meet
The CBSE formula multiplies CGPA by 9.5, so a CGPA of 8.4 is 79.8%. Some universities use different rules. A few multiply by 10, which would make 8.4 equal to 84%, and some use a formula such as (CGPA − 0.75) × 10, which gives 76.5% for the same CGPA. The three answers differ by several points, so the choice of formula matters.
The right formula is the one printed on your university’s grade card or notified by the institution that will read the result. If no formula is given, say which one you used when you write the percentage on an application. Check that the CGPA is on a 10-point scale before you convert, because some institutions use 4-point or 5-point scales.
Frequently asked questions
How do I convert CGPA to percentage?
Multiply your CGPA by 9.5 for the CBSE method. A CGPA of 8.4 gives 8.4 × 9.5 = 79.8%.
How do I convert percentage to CGPA?
Divide your percentage by 9.5. For 79.8%, the CGPA is 79.8 ÷ 9.5 = 8.4.
Does every university use the 9.5 factor?
No. Some universities use ×10 or their own tables. Use the method accepted by the institution or employer you are applying to.
Is 8.5 CGPA equal to 80% marks?
With the CBSE method, 8.5 × 9.5 = 80.75%. Other universities may give a different figure, so check your own university’s rule.
Can I use SGPA instead of CGPA?
SGPA is for a single semester. For an overall percentage, use your final CGPA, unless the form asks for a particular semester.
Will a percentage from this calculator be accepted as official?
Not automatically. It is an approximation using a standard formula. If an official percentage is required, ask your board or university for a conversion certificate.
Why does my university give a different percentage?
Universities choose their own conversion rule, such as CGPA × 9.5, CGPA × 10 or (CGPA − 0.75) × 10. Use the one your university states.
