CGPA to Percentage: The Official Formula for CBSE, VTU, Anna University, AKTU and More

Job applications, admission forms and scholarship portals often ask for your percentage, but your marksheet shows a CGPA. The internet is full of “CGPA × 9.5” calculators, but there is no single national formula. Each board and university publishes its own, and several popular websites quote formulas that the universities never published.

Below are the formulas we could confirm in each body’s own documents. The CGPA to Percentage converter uses exactly these and links to each source.

The formulas

Board / university	Formula	Applies to
CBSE	Percentage = CGPA × 9.5	Class 10 results under the CGPA grading scheme. CBSE calls it an “indicative” percentage (Circular No. 24 of 2010)
VTU	(CGPA − 0.75) × 10	2015, 2017 and 2018 schemes (VTU’s published standard formula)
VTU	CGPA × 10	2022 scheme (BE/B.Tech Regulations 2022, clause 22OB 6.7)
Anna University	CGPA × 10	UG and PG under R-2015, R-2018 and R-2019, as notified for University Departments
AKTU	CGPA × 10	B.Tech ordinances 2016-17 and 2018-19 (clause 15)
JNTU Hyderabad	(CGPA − 0.5) × 10	B.Tech R18 (clause 11.2)
JNTU Kakinada	(CGPA − 0.5) × 10	B.Tech R23 (amendment of December 2025)
Delhi University	CGPA × 9.5	Postgraduate programmes under CBCS (Ordinance IX(8), 2019)
MAKAUT (WBUT)	(DGPA − 0.75) × 10	From MAKAUT’s own table: 6.25 → 55%, 6.75 → 60%, 7.25 → 65%, 7.75 → 70%, 8.25 → 75%

Worked examples

• CBSE, CGPA 8.4: 8.4 × 9.5 = 79.8%
• VTU 2018 scheme, CGPA 8.2: (8.2 − 0.75) × 10 = 74.5%
• VTU 2022 scheme, CGPA 8.2: 8.2 × 10 = 82%
• JNTUH R18, CGPA 7.65: (7.65 − 0.5) × 10 = 71.5%

The VTU example shows why the scheme matters: the same CGPA gives 74.5% or 82% depending on your batch.

Common mistakes

Using × 9.5 for everything. The 9.5 factor is CBSE’s, for Class 10, and Delhi University uses it for postgraduate programmes. Most engineering universities use a different formula.

AKTU with “− 0.75”. Several websites give AKTU’s formula as (CGPA − 0.75) × 10. AKTU’s B.Tech ordinances say CGPA × 10. The “− 0.75” version is VTU’s formula for its older schemes.

Assuming UGC sets a formula. UGC’s Choice Based Credit System guidelines explain how SGPA and CGPA are calculated, but don’t give a percentage conversion. That’s left to each university.

My university isn’t listed

We only list formulas we could read in an official university or board document. For several large universities, including Mumbai, KTU, SPPU, GTU and Calcutta, the formula circulates online only as copies on other sites, so we couldn’t confirm it.

If yours isn’t listed:

1. Check your grade card or transcript. Some print the conversion formula on the back.
2. Look in your academic regulations (search your university’s site for “regulations” with your batch year).
3. Ask your college’s exam section. Some universities issue a conversion certificate on request.

Then choose Other university in the converter and enter the numbers yourself: subtract, multiply by, add.

Calculating CGPA in the first place

If you only have semester grades, use the SGPA & CGPA Calculator. It follows the UGC CBCS method:

• SGPA = Σ(course credits × grade points) ÷ total credits
• CGPA = Σ(semester credits × SGPA) ÷ total credits

UGC’s 10-point letter grades are O = 10, A+ = 9, A = 8, B+ = 7, B = 6, C = 5, P = 4, F = 0. If your university uses different points, you can type them in.

Is the converted percentage official?

Only your university or board can certify a percentage. Several of them, including CBSE, VTU and JNTU, describe the formula as indicative or say it “may be used”. If your transcript states a percentage, quote that one. If a form asks for a percentage and you’re unsure, ask the organisation whether they accept a converted figure or want your CGPA as it is.
