How to Calculate SGPA and CGPA — KTU
A step-by-step guide for Kerala Technological University (KTU) students to calculate SGPA and CGPA for 2024 Scheme and 2019 Scheme using this calculator.
What is GPA?
GPA (Grade Point Average) is a number that represents your academic performance. In KTU, each subject you study is assigned a certain number of credits, and after the exam you receive a letter grade. That letter grade maps to a grade point value. GPA is the weighted average of all those grade points, where subjects with more credits have more influence on the result.
Think of it this way — a 4-credit subject matters more to your GPA than a 1-credit lab, because it carries more weight in the calculation.
KTU Grading System (2024 Scheme)
KTU uses a 10-point grading scale. The grades and their corresponding grade points for the 2024 Scheme are:
| Grade | Grade Point | Performance |
|---|---|---|
| S | 10 | Outstanding |
| A+ | 9 | Excellent |
| A | 8.5 | Very Good |
| B+ | 8 | Good |
| B | 7.5 | Above Average |
| C+ | 7 | Average |
| C | 6.5 | Satisfactory |
| D | 6 | Pass |
| P | 5.5 | Pass (Minimum) |
| F | 0 | Fail |
| FE | 0 | Fail (Eligibility) |
| Ab | 0 | Absent |
Grade points for the 2019 Scheme differ slightly — verify with your official KTU regulations.
What is SGPA?
SGPA (Semester Grade Point Average) is your GPA for one particular semester. It tells you how well you performed in that semester alone.
Example — Semester 1 with 3 subjects:
| Subject | Credit | Grade | Grade Point | Earned GP |
|---|---|---|---|---|
| Mathematics | 4 | S | 10 | 40 |
| Physics | 4 | A+ | 9 | 36 |
| Engineering Workshop | 1 | A | 8.5 | 8.5 |
| Total | 9 | 84.5 |
What is CGPA?
CGPA (Cumulative Grade Point Average) is your overall GPA across all semesters completed. It is not the simple average of your SGPAs — it is a weighted average based on the total credits of each semester.
Every semester contributes to your CGPA based on the total credits it carries. Semesters with more credits have more influence, so consistent performance across all 8 semesters is important for a strong CGPA.
KTU CGPA to Percentage Conversion
For KTU 2024 Scheme and 2019 Scheme, the formula to convert CGPA to percentage is:
Examples:
- CGPA 9.00 → 90.00%
- CGPA 7.50 → 75.00%
- CGPA 6.20 → 62.00%
How to Calculate SGPA and CGPA Using This Calculator
On the home screen, tap KTU B.Tech — 2024 Scheme if you joined B.Tech from 2024 onwards, KTU B.Tech — 2019 Scheme if you joined B.Tech between 2019 and 2023, or Other Schemes & Programmes for KTU M.Tech, MCA, MBA, B.Arch, the 2015 Scheme, and any other credit-based programme.
Choose your branch — for example, Computer Science and Engineering, Civil Engineering, or Mechanical Engineering. Subjects and credits are pre-filled based on the KTU curriculum.
For each subject, select the grade you received (S, A+, A, B+, B, C+, C, D, P, or F) from the dropdown. Credits are pre-filled but can be edited if needed.
After entering grades for a semester, tap the Calculate button at the bottom of that semester card. The SGPA for that semester is shown immediately.
As you calculate each semester, your cumulative CGPA is recalculated and shown in the floating badge at the top of the screen.
Tap View Calculations to see a detailed sheet — earned grade points per subject, the SGPA formula for each semester, and the final CGPA formula with all values filled in.
Other KTU Schemes & Programmes (M.Tech, MCA, MBA, B.Arch, 2015 Scheme)
This calculator also supports KTU programmes outside of B.Tech 2024 and 2019. Each programme may use a different grade point scale — the default scale on these pages is the standard 10-point system used by B.Tech, but you can customise the grade points on any page using the Modify Grading System option (your changes are saved per programme). Open the relevant page directly:
- KTU B.Arch GPA Calculator — for Bachelor of Architecture students
- KTU M.Tech GPA Calculator — works for every M.Tech specialisation (CSE, VLSI, Structural, Power Systems, Communication, Thermal, Manufacturing and more)
- KTU MCA GPA Calculator — for Master of Computer Applications students
- KTU MBA GPA Calculator — for Master of Business Administration students
- KTU 2015 Scheme GPA Calculator — for older B.Tech batches under the 2015 regulation
If your scheme or programme is not in the list above, use the Universal Calculator — a fully flexible calculator where you can:
- Add your own subjects and credits manually
- Add or remove semesters as needed
- Modify the grading system to match your programme's grade point scale using the Modify Grading System option
This works for any KTU programme, MG University, Calicut University, and any other course with a credit-based grading system.
Open Universal Calculator →Frequently Asked Questions
Is this an official KTU tool?
No. This calculator is built and maintained by an individual and is not officially affiliated with Kerala Technological University. Always verify your results on the official KTU portal.
Will my entered grades be saved?
Yes. Your grades are saved in your browser's session storage and remain intact as long as the browser tab is open. Closing the browser will clear the saved data.
How do I calculate SGPA if I have a backlog?
Enter F (0 grade points) for the subject you failed, or Ab if you were absent. The SGPA will reflect accordingly. Once you clear the backlog, update the grade and recalculate.
What is the minimum grade to pass in KTU?
The minimum passing grade in KTU is P (5.5 grade points) for both 2024 and 2019 Schemes. In the 2019 Scheme, lab subjects may use the LP grade (4 grade points) for practical pass. Check your programme regulations for exact criteria.
Can I use this for KTU 2015 Scheme?
Yes — open the KTU 2015 Scheme calculator, or use the Universal Calculator and update the grading system using Modify Grading System to match the 2015 Scheme grade points.
Can I use this for KTU B.Arch (Bachelor of Architecture)?
Yes — open the dedicated KTU B.Arch GPA Calculator. Add your studio, theory and practical courses with credits and grades to compute SGPA and CGPA. If your B.Arch regulation uses a different grade scale, tweak it via Modify Grading System.
Can I use this for KTU M.Tech?
Yes — open the KTU M.Tech GPA Calculator. It works for every M.Tech specialisation (Computer Science, VLSI, Structural, Power Systems, Communication, Thermal, Manufacturing, etc.). The default grade scale follows the standard 10-point system; if your M.Tech regulation uses different grade points, adjust them via Modify Grading System before calculating.
Can I use this for KTU MCA?
Yes — open the KTU MCA GPA Calculator. Add core, elective and lab courses with credits and grades. MCA grade points can differ from B.Tech, so verify against your regulation and use Modify Grading System to update the scale if needed.
Can I use this for KTU MBA?
Yes — open the KTU MBA GPA Calculator. Add core, elective and project courses with credits and grades. MBA programmes may use a different grade scale, so check your regulation and use Modify Grading System to match your programme's grade points.
Do all KTU programmes use the same grade points?
No. KTU B.Tech 2024 and 2019 schemes share the same 10-point letter scale (S, A+, A, B+, B, C+, C, D, P, F), but other programmes — B.Arch, M.Tech, MCA, MBA, and older schemes — can use different grade point values. For any programme outside B.Tech 2024/2019, verify the scale in your official regulation and customise it from the calculator using Modify Grading System. Your custom scale is saved per programme.
What is FE grade in KTU?
FE (Fail — Eligibility) means you were not eligible to write the exam, typically due to attendance shortage or not meeting internal assessment criteria. It carries 0 grade points, same as F.
My CGPA on this calculator differs from KTU results. Why?
Minor differences can occur due to rounding rules applied by KTU, or if your programme uses different credit values. Always treat this calculator as an estimate and verify with your official KTU result sheet.
