The short answer: to convert SGPA to percentage, subtract 0.75 from your SGPA and multiply by 10. That is the official rule under VTU's 2015, 2017 and 2018 schemes, at MAKAUT and at AKTU, and it puts 8 SGPA at 72.50%. It is not universal. VTU's newer schemes, SPPU and Mumbai University each publish something different, and at 8 SGPA their answers range across 12.20 percentage points. Use the calculator above to see all of them before committing to one.
Which SGPA to percentage formula does your university use?
Each formula below comes from the university's own circular or ordinance. The source is named so you can request it from your examination cell by name, which is the version an admissions office will actually accept.
| University | Official formula | Source document | Note |
|---|---|---|---|
| SPPU (Pune) | Banded, six ranges | Circular No. 332-2020 (08-12-2020) | Drops 0.90 points at 8.25 SGPA |
| VTU (2015 / 2017 / 2018 schemes) | (SGPA − 0.75) × 10 | VTU conversion notification | The formula most calculators copy |
| VTU (2021 / 2022 schemes) | SGPA × 10 | VTU conversion notification | Newer schemes dropped the 0.75 offset |
| MAKAUT (WBUT) | (SGPA − 0.75) × 10 | Examination notification, office of the COE | Same expression as VTU's older schemes |
| AKTU | (SGPA − 0.75) × 10 | B.Tech ordinance | Some employers accept SGPA × 10 instead |
| Mumbai University (CBCS) | (7.1 × SGPA) + 11 | CBCS ordinance, Arts / Science / Commerce | Engineering reports SGPI under a separate circular |
If your university is not listed, the rule is usually printed on the reverse of the grade card or posted as an examination-section notification. Do not assume the (SGPA − 0.75) × 10 formula applies just because most calculators use it.
How do you convert SGPA to percentage, step by step?
Read your SGPA off the grade card, apply the formula your university publishes, and the percentage falls out. Most Indian universities use one of four rules, and the multiplier is the only part that changes between them. Here is the whole process worked through at 8.5 SGPA.
Step 1: Read your SGPA off the grade card
SGPA is already credit-weighted, so you do not recalculate it. Your university computed it as the sum of (credit × grade point) for every subject that semester, divided by total credits. If your marksheet prints letter grades but no SGPA, that formula is how you build it.
Step 2: Identify your university's formula
Use the table above, or the circular your examination cell publishes. This step decides your answer, and it is the one most calculators skip.
Step 3: Apply it
Under (SGPA − 0.75) × 10, 8.5 SGPA works out to (8.5 − 0.75) × 10 =77.50%. Under VTU's 2021 and 2022 schemes the same 8.5 gives 85.00%, and under Mumbai University's CBCS equation it gives 71.35%.
Step 4: Check which class that percentage falls in
77.50% lands in the First Class with Distinction band on the scale most Indian universities use. The division table further down covers the rest.
How do you convert a percentage back to SGPA?
Rearrange the same formula and divide where you would have multiplied. If your university multiplies SGPA by 10 and subtracts 7.5, the reverse is (percentage + 7.5) ÷ 10. The table below reverses each published rule and works 75% back through it.
| University | Reverse formula | SGPA from 75% |
|---|---|---|
| VTU (2015 / 2017 / 2018), MAKAUT, AKTU | SGPA = (% ÷ 10) + 0.75 | 8.25 |
| VTU (2021 / 2022 schemes) | SGPA = % ÷ 10 | 7.50 |
| Mumbai University (CBCS) | SGPA = (% − 11) ÷ 7.1 | 9.01 |
| SPPU (Pune) | No single inverse: reverse the band that applies | 8.33 |
SPPU is the awkward one. Because its rate changes between bands, there is no single divisor to reverse; you have to find the band the percentage falls in and reverse that equation. The figure above does that for you.

Why doesn't one formula fit every university?
Because each university publishes its own rule, and only some of them agree. The formula quoted almost everywhere as universal, (SGPA × 10) − 7.5, is genuinely official under VTU's 2015, 2017 and 2018 schemes, at MAKAUT and at AKTU. Outside those cases it is simply the wrong formula, and the table below shows what using it costs.
That same rule is just another way of writing (SGPA − 0.75) × 10, and across a wide middle range it matches SPPU's circular exactly. That coincidence is why it spread so far beyond the universities that actually publish it.
| SGPA | University | Its official result | General formula | Difference |
|---|---|---|---|---|
| 9.60 | SPPU | 92.00% | 88.50% | +3.50 pts |
| 8.00 | VTU 2021 / 2022 scheme | 80.00% | 72.50% | +7.50 pts |
| 8.00 | Mumbai University (CBCS) | 67.80% | 72.50% | -4.70 pts |
| 6.00 | SPPU | 56.25% | 52.50% | +3.75 pts |
SPPU's formula steps down at 8.25 SGPA
Circular 332-2020 defines its bands against round percentages rather than one continuous line, and two of the joins do not meet. At 8.24 SGPA the circular returns 74.90%; at 8.25 it returns 74.00%. A higher SGPA produces a lower percentage. The calculator above reports that honestly rather than smoothing the curve, because smoothing it would put a number on your application that the university would not confirm.
One more caveat on SPPU, and it is the one worth carrying into the examination office: Circular 332-2020 is written to convert CGPA, not a single semester's SGPA. Students apply it to SGPA because SPPU publishes nothing else, and that is a reasonable estimate, but it is not the same thing as an official semester conversion.
Mumbai University's position changed in January 2026
Reporting since January 2026 indicates Mumbai University no longer treats a single formula as a universal standard, with conversions computed from actual marks and a certificate issued on request instead. The CBCS row above covers Arts, Science and Commerce. Engineering results are reported as SGPI and CGPI and convert under a separate circular, which the Mumbai University calculator handles. Treat the Mumbai figures here as indicative and confirm with the examination section before using one on a form.
What your converted percentage means
Division is awarded on the percentage, not on the SGPA, so two students with identical SGPAs at different universities can end up in different classes.
| Percentage | Division / class |
|---|---|
| 90% and above | Distinction |
| 75% – 89.99% | First Class with Distinction |
| 60% – 74.99% | First Class |
| 50% – 59.99% | Second Class |
| 40% – 49.99% | Pass Class |
| 0% – 39.99% | Fail |
Exact cut-offs vary by ordinance, so check yours. Worth separating from this: the thresholds for PG admission, campus placement and government applications are set by the body admitting or recruiting you, not by your university. Read the specific requirement rather than assuming a division clears it.
Where do these formulas come from?
Every formula in the calculator traces to a university notification or to the national grading framework, not to a rule of thumb. These are the starting points for verifying your own:
- Visvesvaraya Technological University (VTU) publishes the scheme-specific conversion notifications. Check whether your marksheet falls under the 2015/2017/2018 or the 2021/2022 scheme before you convert.
- Savitribai Phule Pune University (SPPU) publishes the banded equation in Circular 332-2020. Ask the examination section which rule applies to a single semester.
- MAKAUT, West Bengal carries the (SGPA − 0.75) × 10 offset formula in its examination notifications.
- University Grants Commission (UGC) sets the choice-based credit system guidelines that define SGPA, CGPA, credits and grade points in the first place.
- World Education Services (WES) is the evaluation route most foreign universities expect instead of a self-calculated percentage.
AKTU, Anna University and Mumbai University publish their rules through their own examination sections rather than at a stable public URL, so they are named here without links.
What to do next
If the percentage is for a PG application, a government form or a foreign university, request an official conversion certificate from your examination section rather than submitting a self-calculated figure. Ask for the conversion circular by number at the same time. You will need it if the receiving institution queries the result.
