SGPA to CGPA Calculator
Convert semester SGPAs into your overall CGPA with proper credit weighting, not a simple average. Instant results with the formula shown.
SGPA to CGPA Conversion Explained
Enter your semester SGPAs and get your CGPA instantly. Calculator handles both simple average method and credit weighted method universities actually use, so your result matches what appears on your transcript.
SGPA and CGPA: The Difference in One Line
SGPA is your grade point average for a single semester. CGPA is the running average across every semester you have completed. Each new semester's SGPA feeds into your CGPA, pulling it up or down.
How to Convert SGPA to CGPA
There are two methods and picking the right one matters.
Method 1: Simple Average (Equal Credits)
If every semester carries the same credit load, just average your SGPAs:
CGPA = Sum of all SGPAs ÷ Number of semesters
SGPAs of 7.2, 7.8, 8.0 and 7.5 across four equal semesters give (7.2 + 7.8 + 8.0 + 7.5) ÷ 4 = 7.62.
Method 2: Credit Weighted Average (Different Credits)
When semesters carry different credit loads, the correct formula weights each SGPA by its credits:
CGPA = Σ (SGPA × Semester credits) ÷ Total credits
This is the method university regulations mandate and it is how your institution computes CGPA on your transcript. A 24 credit semester influences your CGPA more than an 18 credit one, exactly as it should.
Worked Example
| Semester | Credits | SGPA | Credit Points (SGPA × Credits) |
|---|---|---|---|
| Semester 1 | 20 | 7.5 | 150 |
| Semester 2 | 20 | 8.0 | 160 |
| Semester 3 | 20 | 7.2 | 144 |
| Semester 4 | 20 | 8.4 | 168 |
| Total | 80 | - | 622 |
CGPA = 622 ÷ 80 = 7.78
The simple average of those four SGPAs would give 7.75. Small difference here, but when cut offs are strict a few hundredths can decide eligibility, which is why the weighted method is the one to trust.
Mistakes That Skew Your CGPA
- Rounding too early: Keep full decimals until the final step. Rounding 8.48 to 8.5 before multiplying compounds the error across semesters.
- Averaging when credits differ: The single most common error. If your semesters are not identical in credit load, the simple average is wrong.
- Dropping failed subjects: A fail typically scores zero grade points but credits still count in your attempted total, dragging the CGPA down. Some universities replace grade on a retake, others average both attempts. Check your institution's rule before excluding anything.
- Forgetting a semester: CGPA covers every completed semester, not just the recent ones you remember fondly.
Using Your CGPA for UK Applications
If you are applying to a UK Master's course, admissions teams will assess your CGPA against their own country specific equivalency tables. As a broad pattern, UK universities asking for a 2:1 equivalent typically expect a CGPA somewhere in 6.5 to 7.5 range on a 10 point scale and First class equivalents usually sit around 7.5 to 8.0 or higher. The exact figure varies by university and by institution you studied at, so always check entry requirements page for your specific course and country.
Send your official transcripts as issued. UK universities convert grades themselves or via UK ENIC, so a self calculated CGPA is for your own reference rather than official use.
Frequently Asked Questions
How do I convert SGPA to CGPA?
Average your SGPAs if all semesters carry equal credits. If credits differ, multiply each SGPA by its semester credits, sum the results and divide by total credits.
Is SGPA the same as CGPA in the first semester?
Yes. With only one semester completed, your CGPA equals your first SGPA.
Why is my CGPA lower than my latest SGPA?
CGPA averages every semester, so one strong recent semester lifts it only gradually. Earlier weaker semesters keep pulling on the average.
Can I convert SGPA directly to a percentage?
Many institutions use Percentage = (SGPA − 0.5) × 10, but formulas vary. Use your university's official conversion for anything formal.
What CGPA do UK universities want for a Master's?
It varies, but a CGPA around 6.5 to 7.5 on a 10 point scale commonly satisfies a 2:1 equivalent requirement. Check the specific course page since thresholds differ by university and country of prior study.
