SGPA to Percentage Calculator
Enter your SGPA and choose your university’s official formula, or the one printed on your grade card. You get the percentage with the working and the source.
Your institution’s formula decides. There is no single national SGPA/CGPA-to-percentage formula in India. If your grade card, transcript or university regulations state a conversion, use that one (pick it above or enter it as a custom formula). When an employer or admissions form asks for a percentage, quote the formula you used and where it comes from, so they can check it.
How to convert SGPA to percentage
- Find your university’s rule. It is usually printed on the grade card or transcript, or stated in the academic regulations.
- Choose it in the calculator. If your university is in the list, pick it and the source appears under the result. Otherwise pick a custom formula and enter the numbers.
- Enter your SGPA (or CGPA). The result is shown to two decimals, the way grade cards print GPAs.
Every university formula we have seen fits one of two shapes: a × SGPA + b (for example 10 × CGPA, or9.5 × CGPA) and (SGPA − x) × y (for example (CGPA − 0.5) × 10). The custom options cover both, so you can apply any rule written on your marksheet.

Why there isn’t one formula
A grade point is a band of marks, not an exact mark, so turning a GPA back into a percentage is a convention rather than a precise reversal. JNTUH’s R22 regulations say it plainly: a letter grade “does not indicate any specific percentage of marks”, only a range. Each university therefore picks its own equivalence, and the same university can change it between schemes. VTU, for instance, used(CGPA − 0.75) × 10 for its 2015, 2017 and 2018 schemes and CGPA × 10 for its 2021 and 2022 schemes.
SGPA or CGPA?
All the official rules listed here are written for the CGPA, usually the final CGPA on the consolidated grade card. If you convert a single semester’s SGPA with the same formula, treat the answer as an estimate for that semester. To get your CGPA from semester results, use the SGPA to CGPA calculator; to work out an SGPA from your subjects, use the SGPA calculator.
Limitations
- We list a university only when we could read its formula in an official document. Absence from the list does not mean a university has no formula.
- Rules change between schemes and batches. Check that the scope shown under the result matches your admission year and programme.
- Some formulas give odd values at the extremes (below the pass mark, or a maximum under 100%). The calculator warns you when a result falls outside 0–100%.
Frequently asked questions
How do I convert SGPA to percentage?
Use the conversion your university publishes. For example, VTU's 2022 regulations and Anna University's Regulations 2021 use CGPA × 10, JNTUH R22 uses (final CGPA − 0.5) × 10, and SPPU uses a different equation for each final grade. Pick your university above, or type in the formula printed on your grade card.
Is SGPA × 9.5 the right formula?
Only if your institution says so. The 9.5 multiplier comes from CBSE, which gives an indicative percentage of 9.5 × CGPA for Class X results issued with grades. It is not a national rule for university SGPA or CGPA.
Should I convert my SGPA or my CGPA?
The official rules we have verified are all written for the CGPA (or final CGPA) on the consolidated grade card. Converting a single semester's SGPA with the same formula gives a reasonable estimate for that semester, but your university may not recognise a per-semester percentage.
My university isn't listed. What should I do?
Check the back of your grade card, your university's academic regulations or ordinance, or ask the examination section. If they give a formula, choose a custom formula above and enter its numbers. We only list formulas we could confirm in an official document.
Why does (CGPA − 0.75) × 10 give a lower percentage than CGPA × 10?
Because it subtracts 0.75 before multiplying by 10, the result is always 7.5 percentage points lower. A CGPA of 8.2 is 82% under CGPA × 10 but 74.5% under (CGPA − 0.75) × 10, and a perfect 10 becomes 92.5%.
What is the difference between SGPA and CGPA?
SGPA (semester grade point average) covers one semester: the credit-weighted average of your grade points in that semester. CGPA (cumulative grade point average) is the same calculation across all semesters so far, so semesters with more credits count for more.
Is anything I type saved or sent anywhere?
No. The calculator runs entirely in your browser and your grades are not sent to a server.
