🎓 CGPA Calculator

Calculate your overall CGPA from semester GPAs and credit hours, or convert CGPA to percentage.

Enter each semester's GPA (out of 10) and its credit hours. Add rows for as many semesters as you need.

Uses the widely-adopted approximation Percentage = CGPA × 9.5 (common under AICTE/VTU-style 10-point grading). Some universities use a different formula (e.g. (CGPA − 0.75) × 10) — always confirm the exact formula with your institution before relying on the converted number officially.

How CGPA Is Calculated

Your Cumulative Grade Point Average (CGPA) is the credit-weighted average of every semester's GPA across your entire program, not a simple average. Semesters with more credit hours count for more, exactly as they do on an official transcript.

CGPA = Σ (Semester GPA × Semester Credits) ÷ Σ (Semester Credits)

CGPA to Percentage Conversion

Many universities on the 10-point CGPA scale (common across India, Pakistan, Bangladesh, and other countries) publish an approximate conversion to a percentage for use on transcripts or job applications. The most widely cited approximation is Percentage = CGPA × 9.5, though a handful of universities instead use (CGPA − 0.75) × 10 or their own institution-specific formula. This tool defaults to the ×9.5 approximation — double-check your university's official conversion policy before using the converted number on any formal document.

❓ Frequently Asked Questions

What's the difference between CGPA and SGPA?
SGPA (Semester Grade Point Average) reflects your performance in a single semester only. CGPA (Cumulative GPA) is the credit-weighted average of all your SGPAs across every semester completed so far in your program.
How do I convert CGPA to a percentage?
The most common approximation on a 10-point scale is Percentage = CGPA × 9.5. However, this varies by university — some use (CGPA − 0.75) × 10, and others have their own official formula, so always verify with your institution before using the converted figure formally.
Can I use this if my university grades on a 4-point scale instead of 10-point?
This calculator is built around the 10-point scale most common in South Asian and several other university systems. If your institution uses a 4-point scale, the same weighted-average formula still applies — just enter your 4-point GPAs instead of 10-point ones; the percentage conversion note won't apply in that case.
Does adding a low-credit elective hurt my CGPA a lot?
Not much — because CGPA is credit-weighted, a course or semester with fewer credit hours has proportionally less influence on your overall CGPA than a heavier semester, even if the grade itself is lower.
Is this the same formula my university's transcript uses?
This tool uses the standard, widely-published credit-weighted average formula used by most universities. A small number of institutions apply additional rules (grade caps, course exclusions, repeat-course policies) — check your official transcript or academic office for any institution-specific adjustments.
