How to convert SGPA to percentage
SGPA (Semester Grade Point Average) is how most Indian universities report your performance for a single semester, on a 10-point scale. The UGC-recommended way to turn that into a percentage is:
Percentage = (SGPA × 10) − 7.5
For an SGPA of 8.4: multiply by 10 to get 84, then subtract 7.5 — 84 − 7.5 = 76.5%.
A few universities apply their own variation of this — some subtract a different offset, others use a flat multiplier. Treat this as a reliable estimate, and confirm the exact figure against your official transcript when it matters for an application.
Definition
What is SGPA?
SGPA is your grade point average for one semester only — calculated from the credit-weighted grades of every subject you took in that term. It resets each semester, unlike CGPA, which accumulates across your entire degree.
Your CGPA is essentially the average of all your semester-wise SGPAs. If you need to convert your overall academic record (not just one term) to a percentage, average your SGPAs into a CGPA first, then apply the same formula.

Reverse Conversion
How to convert percentage back to SGPA
If you already have a percentage and need the equivalent SGPA (for a university form that asks for a 10-point score, for instance), reverse the formula:
SGPA = (Percentage + 7.5) ÷ 10
A percentage of 82% converts back to (82 + 7.5) ÷ 10 = 8.95 SGPA.
Watch Out For
Common mistakes to avoid
Using the wrong multiplier
The 9.5/× 10 − 7.5 formula is a UGC guideline, not a universal law — some universities apply their own offset. Confirm yours before quoting a percentage anywhere official.
Mixing up SGPA and CGPA
SGPA is one semester; CGPA is the cumulative average across all of them. Converting the wrong one gives a percentage that doesn't represent your overall record.
Rounding too early
Round only your final answer, not the SGPA itself before converting — rounding early can shift the percentage by a full point or more over several calculations.
Assuming it's officially binding
A formula-based percentage is an estimate for your own reference. Scholarship forms, government exams, and job applications may require your institution's own certified percentage instead.
Got Questions?
Frequently asked questions
What is the formula to convert SGPA to percentage?
Percentage = (SGPA × 10) − 7.5, per UGC guidelines. An SGPA of 8.4 works out to (8.4 × 10) − 7.5 = 76.5%.
Is this formula the same at every university?
No — this is the most common UGC-recommended method, but some universities apply a different offset or multiplier. Always check your own institution's official conversion policy before submitting a percentage anywhere formal.
How do I convert a percentage back to SGPA?
Reverse the formula — SGPA = (Percentage + 7.5) ÷ 10. A percentage of 76.5% converts back to (76.5 + 7.5) ÷ 10 = 8.4 SGPA.
What's the difference between SGPA and CGPA?
SGPA covers a single semester. CGPA is the cumulative average of your SGPA across every semester you've completed. Use CGPA, not SGPA, when a form asks for your overall academic record.
Can I use this for scholarship or job applications?
It's a reliable estimate for your own planning, but scholarship committees and employers may want the percentage printed on your official transcript rather than a self-calculated one — check what's actually required before relying on the conversion.
Why does my university's percentage differ slightly from this calculator?
Some institutions use a different conversion formula internally, or round at a different step in the calculation. A difference of a percentage point or two is common and not a sign of an error.
