SGPA to CGPA Calculator
Combine semester grades.
Enter each semester SGPA and credits to calculate credit-weighted CGPA.
Semester Grades
Credit-weighted CGPA calculation.
Semester Trend
How It Works
Enter Semester SGPAs
Enter the SGPA you earned in each individual semester.
Add Multiple Semesters
Click 'Add Semester' to include data for every term you've completed.
Enter Credit Hours (Optional)
If semesters have different credit loads, enter credit hours for weighted precision.

SGPA to CGPA Overview
SGPA (Semester Grade Point Average) reflects your performance in a single semester, while CGPA (Cumulative Grade Point Average) reflects your overall performance across every semester completed so far. This calculator converts a list of your semester-wise SGPA scores into one overall CGPA — the figure that typically appears on your final degree transcript.
Why Use This Calculator
- Combine any number of semesters' SGPA into one CGPA
- Supports simple averaging or credit-weighted averaging
- Widely used by students on the 10-point grading system
- Instant results, no manual math required
Calculation Formula
Simple Average (Equal Credits)
CGPA = (Sum of SGPAs) ÷ (Number of Semesters)
Credit-Weighted Average
CGPA = Σ (SGPA × Credits) ÷ Σ (Credits)
Worked example: combining semester SGPAs
You completed three semesters: 8.1 over 18 credits, 8.6 over 20 credits, and 7.9 over 22 credits.
- 1Convert each semester into grade points: 8.1 x 18 = 145.8.
- 2Add the other semesters: 8.6 x 20 = 172 and 7.9 x 22 = 173.8.
- 3Total grade points are 491.6 across 60 credits.
- 4CGPA = 491.6 / 60 = 8.19.
The third semester has the most credits, so it influences CGPA slightly more than the first two semesters.
How this differs from the CGPA calculator
SGPA-to-CGPA starts with individual semester values. The CGPA calculator starts with an existing cumulative value and adds new data.
Common mistakes to avoid
- Do not use a simple average when semesters have different credit loads.
- Do not include remedial or audit semesters unless they appear in official CGPA credits.
- Do not combine percentage marks and SGPA values in the same input table.

Frequently Asked Questions
Is CGPA just the average of all my SGPAs?
Yes, if every semester carries equal credit hours. If credit loads differ, use the credit-weighted formula for an accurate result.
Which universities use the SGPA/CGPA system?
This system is common at many technical and AICTE-affiliated universities in India and at other institutions that follow a 10-point grading structure.
Does one bad semester ruin my CGPA?
It will lower your CGPA, but as more semesters accumulate, the impact of any single term on the overall average shrinks.
Can I recalculate CGPA if I retake a failed course?
Usually yes, depending on your university's grade improvement or backlog-clearing policy — check your academic regulations for the exact rule.
What's considered a good CGPA on the 10-point scale?
This varies by institution and field, but generally 7.5+ is considered solid, and 8.5+ is often viewed as excellent — check placement or admission cutoffs specific to your goals.
Do backlogs or failed courses affect CGPA calculation?
Typically yes, until they are cleared — many universities exclude or specially flag backlog semesters until the course is passed.
Is CGPA rounded when printed on official transcripts?
Often yes, usually to two decimal places, but the exact rounding convention depends on your university's official policy.
Can I calculate CGPA without credits?
Yes, if every semester has equal credit load. If credits differ, use weighted credits for accuracy.
Why is my CGPA lower than the average of my SGPAs?
A lower-SGPA semester may carry more credits, pulling the weighted average down.
Can I include future expected SGPA?
Yes for planning, but label it as a projection rather than an official CGPA.
