Math & Calculator
SGPA & CGPA Calculator
Calculate SGPA from subject credits and grade points, then CGPA across semesters
Grade points follow your university scale — usually 10 for O or S, 9 for A+, and so on. Enter the number your result sheet shows, not the letter.

Working Out One Semester, Then Your Whole Degree
The first tab handles a single semester. Add a row for each subject with its credits and grade point, name it if you want to keep track, and the SGPA updates as you type. The second tab builds your CGPA from every semester you have finished, taking each semester's SGPA and its total credits. Rows can be added or removed freely, so a semester with nine subjects is as easy as one with four, and nothing is locked behind a sign-up.
Why Credits Matter More Than the Number of Subjects
A common mistake is treating every subject as equally important. It is not the count of subjects that matters but their credit weight. Scoring a ten in a one credit lab lifts your SGPA far less than scoring a ten in a four credit core paper, and a poor grade in a heavy subject is correspondingly harder to absorb. Before an exam season, list your subjects by credits and give the top of that list your attention first. The arithmetic rewards it directly.
Predicting What Grades You Need This Semester
The calculator is at its most useful before results, not after. Enter the grade points you realistically expect and watch the SGPA move. If you need a particular CGPA for a placement filter or a scholarship, try different combinations until you find the minimum grades that get you there. That tells you which subjects actually carry the outcome, which is far more useful than a vague intention to do better across the board.
How Backlogs and Repeat Attempts Change the Maths
Universities differ on this and the difference is significant. Some replace the failed grade with the repeat grade, so your CGPA recovers fully. Others record the improved grade but cap it, commonly at the grade point just below the top band. A few keep both attempts in the calculation. Until you clear a backlog, most universities either withhold the SGPA for that semester or compute it only on the subjects you passed, so a figure you calculate yourself may not match the portal.
Turning SGPA Into the Percentage an Application Asks For
Build your CGPA here first, then convert it with the CGPA to percentage tool using your university's own formula. The order matters. Converting each semester separately and averaging the percentages gives a different answer than converting the final CGPA, because semesters carry unequal credits. Employers and application portals expect the conversion applied once, at the end, to the cumulative figure.
Checking Your Result Sheet Against Your Own Calculation
Recomputing your SGPA by hand is worth the two minutes it takes. Portal errors happen, most often when credits are entered wrongly for a lab or an elective, or when a revaluation result has not been carried through. If your number and the portal's differ by more than a rounding step, check the credits column first, since that is where the mistake usually is. Raise it with the examination section while the semester is still current, because corrections get slower once results are ratified.
What a Credit Actually Represents in Your Timetable
A credit is a measure of teaching time, not of difficulty. Under the UGC choice based credit system, one credit usually means one hour of lecture or tutorial per week across a semester, while laboratory and practical work typically needs two hours per week to earn the same single credit. That is why a four credit theory paper meeting four times a week outweighs a two credit lab that occupies a longer afternoon slot. When you copy credits into the calculator, take them from the scheme of examination rather than counting hours on your timetable, because the official credit is what your university uses when it computes the SGPA on your result sheet.
Frequently Asked Questions
Multiply each subject's credits by its grade point, add those products together, then divide by the total credits for the semester. A four credit subject with grade point nine contributes 36. The tool does this as you type, so you only need the credits and grade points from your result sheet.
Enter the number your university assigns, not the letter. Most Indian universities on a ten point scale use 10 for O or S, 9 for A+ or A, 8 for A or B+, and so on down. The mapping is printed on the back of your marksheet or in the academic regulations, and it does vary between universities.
Because semesters rarely carry equal credits. A semester with 26 credits should influence your CGPA more than one with 18. The CGPA tab weights each semester by its credits, which is how universities compute it. Taking a plain average of SGPAs gives a different and usually slightly wrong number.
Yes. The credit-weighted formula is the same across universities on a ten point scale, including VTU, AKTU, Anna University and most autonomous colleges. What differs is the grade point each letter maps to and how backlogs are handled, so take both from your own university's regulations.
No. Everything is calculated in your browser and nothing is uploaded, logged or kept after you close the tab. There is no account and no sign-up. The trade-off is that your subject list is not saved either, so note the SGPA down once you have it.
