CGPA to Percentage Conversion: CBSE and University Formulas

Why the same CGPA gives different percentages

A CGPA is an average of grade points, not of marks, so turning it back into a percentage needs a rule. Each board or university sets its own rule, and some have changed it over the years. Here is what one CGPA of 8.2 becomes under the common formulas:

A gap of almost 13 percentage points can decide whether you clear a 75% eligibility line, so never borrow another university's formula.

CBSE Class 10: CGPA × 9.5

CBSE Class 10 marksheets from the CCE years (roughly 2010 to 2017) gave grades and a CGPA. The marksheet itself said the indicative percentage is 9.5 × the grade point of a subject, and 9.5 × CGPA overall. So a CGPA of 9.4 is 89.3%.

CBSE went back to marks from the 2018 board exam, so newer marksheets show marks and you do not need any conversion. CBSE has also said that it does not calculate an overall percentage, division or distinction. If a form needs one, the college or employer decides how to work it out, including which subjects to count.

University formulas

VTU

VTU's 2022 regulations (students admitted from 2022-23) use Percentage = CGPA × 10, so 8.20 is 82%. The older 2015-16 CBCS regulations used (CGPA − 0.75) × 10. Check which scheme you were admitted under.

Anna University

The 2023 B.E./B.Tech regulations print the percentage on the consolidated grade sheet using CGPA × 10. If your grade sheet already shows a percentage, use that figure.

AKTU

The revised B.Tech ordinance (AICTE model curriculum, 2018-19 onward) gives CGPA × 10. Some older batches were told to use (CGPA − 0.75) × 10, so confirm with your college's exam cell.

Mumbai University

For years Mumbai University used 7.1 × CGPA + 11. In January 2026 it was reported to have replaced formula conversion with a percentage worked out from your actual marks (total obtained ÷ total maximum × 100), issued by the college as a conversion certificate on request. Ask your college for the certificate rather than using the old formula.

Savitribai Phule Pune University (SPPU)

SPPU uses a different formula for each grade band instead of one multiplier:

On this table a CGPA of 8.2 falls in band A: 10 × 8.2 − 7.5 = 74.5%.

MAKAUT, GTU and Delhi University

• MAKAUT (WBUT): (CGPA or DGPA − 0.75) × 10.
• GTU: commonly reported as (CGPA − 0.5) × 10. GTU has its own equivalence notification, so check it.
• Delhi University: CGPA × 9.5, introduced in 2018 for postgraduate admission cut-offs.

IITs, NITs and UGC

The UGC's CBCS guidelines define the 10-point grade scale and how SGPA and CGPA are calculated, but they do not give a CGPA-to-percentage formula. IITs generally do not convert at all: IIT Delhi's placement and admission shortlisting says it will not accept a conversion by the candidate or the institute and looks only at the grade sheet. Some NITs have issued their own notices, so ask your institute.

Step by step

1. Look for a percentage or a conversion formula on the back of your grade sheet or transcript. If it is there, use it.
2. If not, find your university's latest conversion circular, or ask the exam cell for a conversion certificate.
3. Check which regulation or scheme you were admitted under, because the formula can change between batches.
4. Apply the formula and keep two decimals.
5. Where a form asks you to attach proof, attach the university's certificate, not your own calculation.

For India Post GDS forms, CGPA is converted with the 9.5 factor. Our GDS Percentage Calculator does this for you.
