How to Use the SGPA to CGPA Calculator
Converting your SGPA scores to CGPA is straightforward using our tool. Follow these simple steps to get your cumulative grade point average instantly:
Step 1 – Select Your Grading Scale
First, choose the grading scale used by your university. Most institutions use one of three standard scales:
- • 10-Point Scale: Common in Indian universities like VTU, Anna University, JNTU, Mumbai University, and most state technical universities. SGPA ranges from 0 to 10.0.
- • 5-Point Scale: Used by some international universities and select Indian institutions. SGPA ranges from 0 to 5.0.
- • 4-Point Scale: Standard in US universities and many international institutions. SGPA ranges from 0 to 4.0.
Step 2 – Enter Your Semester SGPAs
You have two methods to calculate your CGPA:
Method 1: Enter Individual SGPAs
Enter the SGPA for each semester separately. Click "Add Semester" if you need more input fields. For example:
- • Semester 1 = 8.2
- • Semester 2 = 8.5
- • Semester 3 = 8.8
- • Semester 4 = 9.0
Method 2: Enter Total SGPA
If you already have the sum of all your SGPAs, simply enter the total and the number of semesters. For example, if your total is 34.5 for 4 semesters, enter both values.
Step 3 – Get Your Result Instantly
Click the Calculate button to view your CGPA instantly. The calculator uses the standard formula: CGPA = (Sum of all SGPAs) ÷ (Total number of semesters). The result can be noted down, screenshot, or used for college applications, scholarship forms, and job applications.

Privacy: Your inputs are processed instantly in your browser and are not stored or transmitted. This helps maintain confidentiality for academic data.
What are SGPA and CGPA?
In most universities, grades are reported term‑wise first (SGPA) and then cumulatively (CGPA). Understanding both helps you track short‑term progress and long‑term performance.
- SGPA (Semester GPA): The grade point average for a single academic semester; often credit‑weighted: (Σ (Course Grade Point × Course Credits)) ÷ (Σ Course Credits).
- CGPA (Cumulative GPA): The overall average across all completed semesters. Either simple average of SGPAs or (Σ All Grade Points × Credits) ÷ (Σ Total Credits) when credit weighting is applied.
Example progression: Semester SGPAs might be 8.5, 8.8, 9.0, 8.7 — these indicate upward consistency. The CGPA after four semesters (simple average) would be (8.5 + 8.8 + 9.0 + 8.7) ÷ 4 = 8.75.
At CGPA Online Calculator we implement the widely accepted calculation patterns used by major universities (VTU, Anna University, JNTU, US 4‑point institutions, etc.). Always verify final official numbers against your transcript—institutions may round or apply credit weighting.
Why it matters: CGPA is used for internships, higher education, scholarship thresholds, international applications, and employment screening. Accurate conversion helps maintain transparency and trust in academic reporting.
Understanding the SGPA to CGPA Calculation
Converting your SGPA scores into CGPA is straightforward once you understand the basic formula. At CGPA Online Calculator, we make this calculation instant and accurate for all grading scales.
The Standard CGPA Formula
The universally accepted formula for calculating CGPA from SGPA is simple:
CGPA = (Sum of all SGPAs) ÷ (Total number of semesters)
This formula applies to all grading scales whether you're on a 10-point, 5-point, or 4-point system. The key is to add up all your individual semester SGPAs and divide by the total number of semesters you've completed.
Credit‑Weighted CGPA (when applicable)
CGPA = (Σ (Semester SGPA × Semester Credits)) ÷ (Σ Semester Credits)
Some institutions compute CGPA using credit weighting. Our calculator uses the simple average of SGPAs by default—this matches what most Indian universities publish on transcripts. If your university mandates credit weighting, confirm the policy in your exam rules and compute using the above formula.
Rounding and Precision
Universities commonly round CGPA to 2 decimals (some to 1). We display 2 decimals for clarity. For official reporting, always follow your institution’s rounding convention.
Step-by-Step Calculation Example
Let's walk through a real example to see how the calculation works:
Given SGPAs:
- Semester 1 SGPA = 8.2
- Semester 2 SGPA = 8.5
- Semester 3 SGPA = 8.8
- Semester 4 SGPA = 9.0
Calculation:
Sum of all SGPAs = 8.2 + 8.5 + 8.8 + 9.0 = 34.5
Total number of semesters = 4
CGPA = 34.5 ÷ 4 = 8.625 (rounded to 8.63)
So if you've completed 4 semesters with these SGPAs, your overall CGPA would be 8.63. This single number represents your cumulative academic performance across all semesters.
Important Points to Remember
All semesters count equally: Each semester's SGPA has equal weight in the calculation, regardless of the number of credits or subjects. The simple average method is used by most universities.
Include all completed semesters: Make sure to include every semester you've completed, even if you had a lower SGPA in one or two semesters. CGPA represents your overall performance.
Grading scale consistency: Ensure all your SGPA values are on the same grading scale (all on 10-point, or all on 5-point, etc.). Mixing different scales will give incorrect results.
FAQ – SGPA to CGPA Calculator
1. What is the difference between SGPA and CGPA?
SGPA (Semester Grade Point Average) represents your academic performance for a single semester only. It is calculated based on the grades you receive in all courses during that particular semester. CGPA (Cumulative Grade Point Average), on the other hand, is the average of all your SGPAs across all completed semesters. While SGPA shows your performance in one term, CGPA gives a comprehensive view of your overall academic achievement throughout your entire degree program. For example, if you have 4 semesters with SGPAs of 8.2, 8.5, 8.8, and 9.0, your CGPA would be the average: (8.2+8.5+8.8+9.0)÷4 = 8.625. Universities and employers typically focus on CGPA when evaluating candidates because it reflects consistent long-term performance rather than a single semester's results.
2. How do I calculate CGPA from SGPA?
Calculating CGPA from SGPA is straightforward using the standard formula: CGPA = (Sum of all SGPAs) ÷ (Total number of semesters). Here's the step-by-step process: First, collect all your SGPA scores from each completed semester (you can find these on your semester mark sheets or transcripts). Second, add up all the SGPA values to get the total sum. Third, count how many semesters you've completed. Fourth, divide the total SGPA sum by the number of semesters. For example, if your SGPAs are 7.8, 8.2, 8.5, 8.9, 9.1, and 9.3 for six semesters, the calculation would be: Sum = 7.8+8.2+8.5+8.9+9.1+9.3 = 51.8, then CGPA = 51.8 ÷ 6 = 8.63. Our calculator does this instantly for you, supporting any number of semesters and all grading scales (10-point, 5-point, 4-point).
3. Does each semester's SGPA have equal weightage in CGPA calculation?
In the standard CGPA calculation method used by most universities, yes, each semester's SGPA carries equal weight regardless of the number of subjects or credits in that semester. This is called the simple average method. For example, whether Semester 1 had 5 subjects or Semester 2 had 7 subjects, both SGPAs are given equal importance in the final CGPA calculation. However, some universities use a credit-weighted system where semesters with more credits have higher weightage. In such cases, the formula becomes: CGPA = (Sum of all SGPA × Credits) ÷ (Total credits). Always check your university's official grading policy to confirm which method they use. Most Indian universities follow the simple average method, which our calculator implements by default.
4. Can I calculate CGPA if I haven't completed all semesters yet?
Yes, absolutely. You can calculate your CGPA at any point during your degree program using the semesters you've completed so far. This is often called provisional CGPA or interim CGPA. For instance, if you're in a 4-year degree program (8 semesters total) and you've completed only 3 semesters with SGPAs of 8.0, 8.5, and 8.8, you can calculate your current CGPA as: (8.0+8.5+8.8) ÷ 3 = 8.43. This provisional CGPA is useful for internship applications, scholarship forms, or tracking your academic progress. However, remember that your final CGPA will change as you complete more semesters. Many students use this feature to set targets for upcoming semesters to achieve their desired final CGPA.
5. Which grading scales are supported for SGPA to CGPA conversion?
Our SGPA to CGPA calculator supports all three major grading scales used worldwide. The 10-Point Scale is the most common in Indian universities like VTU, Anna University, JNTU, Mumbai University, and most state technical universities, where SGPA ranges from 0 to 10.0. The 5-Point Scale is used by some international universities and select Indian institutions, with SGPA ranging from 0 to 5.0. The 4-Point Scale is the standard in US universities and many international institutions, where SGPA ranges from 0 to 4.0 (often corresponding to letter grades A, B, C, D, F). The calculation method remains the same across all scales—you simply average your semester SGPAs. Our calculator automatically validates that your entered SGPA values don't exceed the selected scale's maximum, ensuring accurate results every time.
6. How accurate is this SGPA to CGPA calculator?
We implement the same arithmetic process published in academic regulations of leading universities: simple average of valid semester grade points (or credit‑weighted where specified). Input validation prevents out‑of‑range values and empty submissions. Minor differences can arise due to institutional rounding rules (e.g. truncation vs bank rounding) or exclusion policies for improvement exams. Treat this result as an indicative academic reference; your official CGPA remains what appears on the university transcript.
7. Can I use this calculator for all academic programs and degrees?
Yes, our SGPA to CGPA calculator works for all academic streams and degree levels. The SGPA to CGPA conversion formula is universal and applies regardless of your field of study. This includes Engineering & Technology programs like B.Tech, B.E., M.Tech, Diploma in all branches (Computer Science, Electronics, Mechanical, Civil, Electrical, etc.). It also works for Management & Commerce degrees such as BBA, MBA, PGDM, B.Com, M.Com, and CA. Science programs including BSc, MSc, B.Pharma, M.Pharma, Biotechnology, and all specializations are supported, as well as Arts & Humanities like BA, MA, BFA, MFA, and Journalism. Professional courses including Law (LLB, LLM), Architecture (B.Arch, M.Arch), and Medical related courses also use this calculator. The formula depends on your grading scale, not your degree type. Whether you're studying engineering or arts, the CGPA calculation method remains the same.
8. What should I do if my SGPA values are on different grading scales?
Normally, all your semester SGPAs should be on the same grading scale throughout your degree program. If you find that your SGPAs are on different scales (which is very rare), you cannot directly calculate CGPA by averaging them. You would need to convert all SGPAs to a common scale first. For example, if Semester 1-3 used a 10-point scale but Semester 4 onwards switched to a 5-point scale, you must convert all to either 10-point or 5-point before averaging. The conversion would typically be: From 10-point to 5-point: multiply by 0.5 (e.g., 8.0 becomes 4.0), or From 5-point to 10-point: multiply by 2 (e.g., 4.0 becomes 8.0). However, such situations are extremely uncommon. If you encounter this, contact your university's examination department for official guidance on how to calculate your CGPA, as they may have specific conversion policies.
9. How can I improve my CGPA in remaining semesters?
Use the projection formula to plan: Required SGPA per remaining semester = [(Target CGPA × Total Semesters) − Sum of Completed SGPAs] ÷ Remaining Semesters. Example: Target CGPA 8.5 over 8 semesters; completed 4 with SGPAs 7.8, 8.0, 8.2, 8.4 (sum = 32.4). Target total = 8.5 × 8 = 68.0. Remaining sum needed = 68.0 − 32.4 = 35.6. Remaining semesters = 4. Required average SGPA = 35.6 ÷ 4 = 8.9. Focus areas: consistent attendance, early concept revision, formative assessment performance, and prioritizing credit‑heavy courses (these have larger impact if your institution uses credit weighting).
10. Why do some universities use credit weighting while others use simple averaging?
Credit weighting gives proportional influence to courses/semesters with more instructional hours or academic depth, aiming for finer granularity in performance evaluation (common in US and some European systems). Simple averaging simplifies student understanding and administrative calculation, prevalent in many Indian technical universities where semester credit loads are roughly balanced. Always check your academic regulations—if they publish a formula referencing total credits, you should apply the credit‑weighted approach for formal calculations.
11. Is my data stored or shared when I use this calculator?
No. All calculations occur client‑side (in your browser). We do not transmit, persist, or log your SGPA inputs. Clear the page or hit reset to remove values. For additional assurance, you can disconnect from the internet after loading the page—the functionality will still work.
