GPA vs CGPA — What's the Difference?
GPA, CGPA, SGPA — every academic acronym explained, plus how each one converts between the US 4.0, Indian 10-point and Pakistani HEC scales.
Every student applying abroad runs into a confusing alphabet soup: GPA, CGPA, SGPA, percentage, letter grade. This short guide untangles all of them and tells you which number to use where.
The short answer
- GPA (Grade Point Average) — usually a US-style 4.0 scale single-term number.
- CGPA (Cumulative Grade Point Average) — average across all semesters. Often called "cumulative GPA" in the US.
- SGPA (Semester GPA) — Indian/Pakistani term for a single-semester GPA.
In the US, "GPA" usually implies cumulative GPA in conversation. In India and Pakistan, GPA usually means single-semester and CGPA means cumulative — though the conventions vary.
Why the same word means different things
The US uses a 0.0–4.0 scale almost universally. Indian universities typically use a 10-point scale; some use 7-point (Mumbai University) or 9-point (CBSE). Pakistan's HEC standardised on 4.0 (some legacy institutions still on 5.0). When someone says "my CGPA is 8.5," the maximum could be 10 (India), 4.0 (Pakistan), or 4.0 (US) — and the percentage equivalent is wildly different in each case.
How to compare across scales
Convert everything to a percentage first, then make comparisons. The CGPA to percentage tool on allgradecalculator.com handles every common formula:
- CBSE India: % = CGPA × 9.5
- General Indian universities: % = (CGPA − 0.75) × 10
- Anna University: % = (CGPA − 0.5) × 10
- VTU: % = (CGPA − 0.75) × 10
- Mumbai University: % = 7.1 × CGPA + 11
- HEC Pakistan (4.0): % = (CGPA / 4.0) × 100
- HEC Pakistan (5.0): % = (CGPA / 5.0) × 100
Example: when 8.5 is not equal to 8.5
| Source | CGPA 8.5 → percentage |
|---|---|
| CBSE India (10-point) | 80.75 % |
| General Indian universities (10) | 77.50 % |
| Anna University (10) | 80.00 % |
| Mumbai University (7-point) | not valid (max 7) |
| HEC Pakistan (4.0) | not valid (max 4) |
Same number, very different meanings.
What does a US university expect?
US universities convert everything to a 4.0 GPA for evaluation. Some do this internally with a credential evaluator (WES, ECE, IERF). Others ask you for the conversion. The CGPA to GPA converter on allgradecalculator.com is the fastest way to get a defensible 4.0 GPA from any input scale.
What does an Indian or Pakistani employer expect?
Most Indian and Pakistani employers use percentage as the cut-off. A 60% requirement is common for entry-level jobs; 70% or 75% for premium roles. Always provide both your CGPA and the converted percentage on your CV.
SGPA, CGPA, and credit weighting
Both SGPA and CGPA are credit-weighted averages — a 4-credit course counts twice as much per grade point as a 2-credit course. Use the SGPA to CGPA calculator to compute your cumulative number from semester SGPAs.
A practical playbook
- Find your CGPA on your most recent transcript.
- Identify the scale (10-point, 4.0, etc.) — usually printed in the header.
- Convert to a percentage using the right formula.
- If applying to the US, convert further to a 4.0 GPA.
- Cite all three numbers on your CV: CGPA (with scale), percentage, GPA-equivalent.
