What Is the AKTU Grading System?

The AKTU grading system explained refers to the structured method the university uses to assess academic performance. Instead of simply using marks or percentages, AKTU assigns grade points based on the marks obtained in each subject. These grade points are then weighed by the number of credits assigned to the course. The outcome is a credit-weighted performance metric called CGPA (Cumulative Grade Point Average).

This system is used to:

Maintain a consistent evaluation standard across all affiliated colleges
Provide a normalized performance measure
Assess academic standing for placements, higher studies, and certificates

AKTU uses a 10-point scale with specific grade point assignments based on marks obtained. This system helps compare academic performance across different semesters and programs fairly.

AKTU Official Grading Scale

The foundation of the AKTU grading system is the grade point table, which maps marks to letter grades and grade points:

Marks (%)	Letter Grade	Grade Point
90–100 %	O	10
80–89 %	A+	9
70–79 %	A	8
60–69 %	B+	7
50–59 %	B	6
45–49 %	C	5
< 45 %	F (Fail)	0

This table is a standard assessment criterion for most undergraduate (e.g., B.Tech) and postgraduate programs under AKTU.

👉 Note: F grade indicates failure in that subject. The credit weight is included in total credits, but the grade point is zero, dragging down SGPA/CGPA until the subject is cleared.

How to Calculate SGPA (Semester Grade Point Average)

Each semester’s performance is summarized by the SGPA, which is calculated as a weighted average of the grade points of all courses taken that semester. The official AKTU SGPA formula is: $\textbf{SGPA} = \frac{\sum (\text{Credit of Course} \times \text{Grade Point})}{\text{Total Credits of Semester}}$ SGPA=Total Credits of Semester∑(Credit of Course×Grade Point)

Example:

Course Code	Credits	Marks	Grade	Grade Point
EEC101	4	82	A+	9
MAT101	4	75	A	8
PHY103	3	68	B+	7
CP101	3	58	B	6

Weighted points = (4×9) + (4×8) + (3×7) + (3×6)
= 36 + 32 + 21 + 18 = 107

Total credits = 4 + 4 + 3 + 3 = 14 $SGPA = 107 ÷ 14 ≈ 7.64$ SGPA=107÷14≈7.64

Your semester SGPA = 7.64 (rounded to two decimals).

How to Calculate CGPA (Cumulative Grade Point Average)

Once you calculate SGPA for each semester, the CGPA is calculated as a weighted average across all completed semesters: $\textbf{CGPA} = \frac{\sum (\text{SGPA} \times \text{Semester Credits})}{\text{Total Credits of All Semesters}}$ CGPA=Total Credits of All Semesters∑(SGPA×Semester Credits)

So, if you have:

Semester	SGPA	Credits
Sem 1	7.64	14
Sem 2	8.12	15
Sem 3	7.80	15
Sem 4	8.20	15

Weighted total = (7.64×14) + (8.12×15) + (7.80×15) + (8.20×15)
= 106.96 + 121.8 + 117 + 123 = 468.76

Total credits = 14 + 15 + 15 + 15 = 59 $CGPA = 468.76 ÷ 59 ≈ 7.95$ CGPA=468.76÷59≈7.95

Final CGPA = 7.95

How to Calculate CGPA from SGPA (Quick Guide)

Many AKTU students search for “calculator CGPA from SGPA of AKTU”. The simplest way is:

Find SGPA of each semester
Multiply each SGPA by that semester’s total credits
Add all weighted points
Divide by sum of total credits

This gives your cumulative AKTU CGPA.

How to Convert CGPA to Percentage (AKTU Formula)

After calculating CGPA, you often need the percentage equivalent—especially for placements, internships, higher-education applications, and scholarship eligibility.

The official relationship used by many AKTU colleges is: $\textbf{Percentage} = (\text{CGPA} – 0.75) \times 10$ Percentage=(CGPA−0.75)×10

For CGPA = 7.95: $Percentage = (7.95 – 0.75) × 10 = 7.20 × 10 = 72\%$ Percentage=(7.95−0.75)×10=7.20×10=72%

This is not a universal formula but widely used in AKTU affiliated colleges. Always check your college’s grading rules if your department uses a specific conversion chart.

Common Student Queries About AKTU Grading

Practical Example Table

Below is a sample table showing semester SGPA and weighted credit points:

Semester	Credits	SGPA	SGPA × Credits
1	14	7.64	106.96
2	15	8.12	121.80
3	15	7.80	117.00
4	15	8.20	123.00
Total	59		468.76

$CGPA = 468.76 ÷ 59 ≈ 7.95$ CGPA=468.76÷59≈7.95

This aggregated process ensures your CGPA reflects all your academic effort across semesters fairly.
