CGPA vs GPA vs Percentage: A Complete Comparison

How CGPA, GPA and percentage grading systems differ, when each is used, and how to convert accurately between them for admissions and jobs.

Three systems, one transcript

GPA, CGPA and percentage are three different ways of expressing the same idea: "how well did you do overall?" Each answers the question with a different scale and a different weighting rule. If you're applying to schools or jobs across countries, you'll be asked to translate between them constantly.

GPA — Grade Point Average

Scale: 0.0 to 4.0 (some scales cap at 4.3 or 5.0 for weighted high-school GPAs).

Where: United States (default), Pakistan (HEC), Bangladesh (universities), Saudi Arabia, and most institutions that model their transcripts on US universities.

Formula: weighted average of grade points by credit hours per course. A → 4.0, B → 3.0, C → 2.0, D → 1.0, F → 0.0.

Usually issued per semester as SGPA and overall as CGPA. See our complete guide to the 4.0 GPA scale.

CGPA — Cumulative Grade Point Average

Scale: 0.0 to 10.0 in India (UGC, CBSE, AICTE), 0.0 to 4.0 in Pakistan and Bangladesh universities, 0.0 to 5.0 for Bangladesh HSC/SSC.

Where: India, Bangladesh, Malaysia, Nepal, and any UGC-affiliated university.

Formula: weighted average of SGPAs by credit hours per semester. The letter → grade point mapping varies by university — VTU is different from Anna University is different from JNTUH.

The 10-point CGPA and the 4.0 GPA are not the same number rescaled — they use different letter cutoffs and rounding conventions, which is exactly why WES, IIE and other evaluators exist.

Percentage

Scale: 0% to 100%.

Where: UK universities (as %), UAE, Pakistan (school-level), India (Class X/XII boards report both), and any institution that publishes raw marks.

Formula: total marks obtained divided by total marks possible, times 100. It's the simplest system and the easiest to compare across subjects.

Common conversion formulas

From → To	Formula	Example
CGPA (10) → %	CGPA × 9.5	8.4 → 79.8%
CGPA (10) → % (MAKAUT)	(CGPA − 0.75) × 10	8.4 → 76.5%
% → CGPA (10)	% ÷ 9.5	76% → 8.0
CGPA (4) → %	CGPA × 25	3.6 → 90%
% → CGPA (4)	% ÷ 25	82% → 3.28
CGPA (10) → GPA (4)	(CGPA / 10) × 4 (rough)	8.4 → 3.36
SGPA → CGPA	Σ(SGPA × credits) / Σ credits	see below

Formulas differ by university. Anna University publishes CGPA × 10, VTU publishes (CGPA − 0.75) × 10, some universities use grade-band lookup tables instead. Always check your official transcript legend before you rely on a single conversion.

Worked example: SGPA → CGPA

Three semesters:

Sem 1: SGPA 8.2, 22 credits → 180.4 weighted points
Sem 2: SGPA 8.6, 24 credits → 206.4
Sem 3: SGPA 8.9, 21 credits → 186.9

CGPA = (180.4 + 206.4 + 186.9) / (22 + 24 + 21) = 573.7 / 67 = 8.56.

Do it interactively in the SGPA to CGPA calculator.

Which one should you report?

US undergrad admissions: your school's official GPA (weighted if issued that way). Convert the transcript to a 4.0 scale.
US grad admissions from India: both your 10-point CGPA and a WES-style 4.0 conversion. Many application portals ask for one, then verify via WES.
UK / Europe: percentage or the local equivalent (First, 2:1, 2:2, Third). ECTS credits and grades if you're moving inside Europe.
Employers: whichever your university issues on the transcript. Never invent a scale.

Common mistakes when converting

Applying CBSE's 9.5 multiplier to a non-CBSE 10-point transcript.
Rounding an SGPA to two decimals before averaging — always weight the raw value.
Assuming a 3.5 US GPA = an 8.75 Indian CGPA. It usually doesn't; WES's lookup is not linear.
Treating percentage from a US course (curved) the same as a percentage from an Indian board (absolute scale).

Frequently asked questions

Is CGPA the same as GPA? No. GPA usually refers to the US-style 4.0. CGPA refers to the cumulative version on whatever scale your institution uses — often 10.0.

Which is more accurate — CGPA or percentage? Both are exact in their own system. Neither is more "accurate"; they're rescalings of the same underlying performance.

Do universities accept a converted GPA? Yes, but they'll usually verify via a credential evaluator (WES, ECE, IIE) or their own international admissions office.
