Six precision-built calculators for students across every Indian university. Percentage to CGPA, SGPA conversions, GPA, marks — all free, all instant, no signup.
Each tool below is fully functional — built with verified university formulas, instant results, and no data stored anywhere.
Convert your percentage back to CGPA using your university's official formula.
Use CalculatorAggregate multiple semester SGPAs (weighted by credits) into your cumulative CGPA.
Use CalculatorConvert your semester GPA directly to a percentage for any major Indian university.
Use CalculatorCalculate your GPA from individual subject grades and credit hours in seconds.
Use CalculatorFind your overall percentage from marks scored across multiple subjects at once.
Use CalculatorWork out what score you need in your final exam to hit your target grade or CGPA.
Use CalculatorNeed to convert a percentage back into CGPA? This tool reverses the standard conversion formula — so if a job application or foreign university is asking for your GPA after you only have a percentage certificate, you're covered.
Simply enter your percentage and choose your university — the calculator applies the exact inverse formula used by your institution.
Example: 80% ÷ 9.5 = 8.42 CGPA
Results are capped at your scale's maximum (10, 5, or 4) and always shown to 2 decimal places.
SGPA (Semester Grade Point Average) is your GPA for one semester. CGPA is the cumulative version — a weighted average of all your semester SGPAs, factoring in the total credits for each semester.
Add each semester's SGPA and its total credits below. The calculator gives you your exact CGPA, which is what appears on your final degree certificate.
Each semester is weighted by how many credits it carries, not just averaged equally.
A semester with 24 credits has more weight than one with 18. If you score 8.5 in a heavy-credit semester and 7.0 in a light one, your CGPA will be closer to 8.5 — not the simple average of 7.75.
This is why students sometimes find their CGPA is higher or lower than they expected from a simple semester average.
Add one row per semester. Enter your SGPA and total credits for that semester.
Your SGPA is your GPA for a single semester. Converting it to percentage works exactly the same way as converting your overall CGPA — just enter your semester GPA and your university below.
This is useful when internships, job portals, or exchange programs ask for a semester-by-semester percentage breakdown instead of your overall CGPA.
The same formula as CGPA to %, since SGPA is simply a single-semester CGPA.
Haven't received your official SGPA yet? Calculate it yourself from your subject-level grades and credit values. Enter each subject, select your grade, and input the credit hours.
This tool uses the standard 10-point grading scale used by most Indian universities (CBSE, VTU, Anna University, etc.).
| Grade | Points | % Range | Meaning |
|---|---|---|---|
| O | 10 | 90–100% | Outstanding |
| A+ | 9 | 80–89% | Excellent |
| A | 8 | 70–79% | Very Good |
| B+ | 7 | 60–69% | Good |
| B | 6 | 50–59% | Above Average |
| C | 5 | 45–49% | Average |
| P | 4 | 40–44% | Pass |
| F | 0 | <40% | Fail |
Enter each subject with its grade and credits. Name is optional.
Got your raw marks for each subject? This calculator finds your overall percentage across all subjects — whether they have equal or different maximum marks. Add as many subjects as you like.
Use this before exam results are processed into grades, or whenever a form asks for your "aggregate percentage" from raw marksheets.
All subjects are aggregated into one overall percentage, not averaged subject-by-subject.
Enter marks obtained and maximum marks for each subject.
You know your current marks and your target grade. But what do you need to score in the final exam to get there? This calculator works backwards to give you your required score — so you know exactly what you're aiming for.
Whether you want Distinction, First Class, or just need to pass — enter your current standing and let the tool tell you what's achievable.
Where w₁ = internal weight, w₂ = final exam weight (both as decimals)
Typical university weighting: 30% internal + 70% external. Always check your university's scheme.
Whether you're a first-year engineering student trying to understand your SGPA, a final-year student converting your CGPA for a job application, or a postgraduate preparing documents for a US university — this toolkit covers every calculation you'll need.
Each calculator uses the officially published formula from the relevant university or board. For CBSE and most state boards, that's the well-established CGPA × 9.5 formula. For VTU, Anna University, Mumbai, GTU, SPPU, MAKAUT, KTU, AKTU, and BPUT, we use each institution's specific published conversion. Results are rounded to two decimal places and capped at logical maximums.
For formal submissions (job applications, university admissions, visa documents) always cross-reference with your official transcript or registrar — our tools are optimized for self-reference and academic planning.
Our main calculator supports 10 universities, 3 grading scales, and shows your full result in one click.
