SGPA Calculator

Multiply each grade point by the credits that course carries, add the results, then divide by the total credits. Nothing more.

Take three courses. A four-credit paper graded O is worth 10 points, so it contributes 40. A three-credit paper graded A is worth 8 points, contributing 24. A two-credit lab graded O contributes 20. That is 84 points across 9 credits, and 84 divided by 9 is an SGPA of 9.33.

The credits are the whole point. They are the weights, and they are why your SGPA is almost never the plain average of your grade points. Averaging the points instead would have given a different figure the moment the credits stop matching.

Suppose you score a 10 in a one-credit lab and a 6 in a four-credit core paper. Averaging the grade points suggests 8.0, which looks respectable. Weighting by credits gives 6.8, because the paper you struggled with counted four times as heavily.

That gap is not a rounding detail. It is the difference between a first class and a borderline result on many transcripts, and it always favours the same direction: the courses with the most credits are the ones worth protecting.

It also has a practical consequence when you plan a semester. A high grade in a small elective moves your SGPA barely at all, while a mid grade in a heavy core paper moves it a lot. If you are choosing where to spend the last fortnight before exams, spend it where the credits are.

You apply the rule your own university prints, and there is no single national one. Three are in wide use, and all three are built in here.

The first multiplies your SGPA by 9.5, a convention that began with a school board and spread far beyond it. The second multiplies by 10, which several engineering universities use. The third subtracts 0.75 and then multiplies by 10; if your handbook words it as multiply by 10 and then subtract 7.5, that is the same arithmetic written the other way round.

Look at what that means for one number. An SGPA of 8.0 becomes 76 percent, 80 percent or 72.5 percent depending only on which rule you were handed. Seven and a half points is enough to move you across a recruiter cut-off, which is why this tool refuses to choose for you and prints the formula next to every answer it gives.

Two cautions worth having in writing. Published conversion charts often disagree with each other about the very same university, so a chart you found on a search result is not evidence. And if a form is going to an employer, a scholarship body or an overseas admissions office, the figure that counts is the one on an official conversion certificate from your examination office, not the one from any calculator, including this one.

A failed course normally scores zero grade points while its credits stay in the divisor. It hurts twice: it adds nothing to the top of the fraction and it makes the bottom bigger.

Two courses of four credits each, one graded O and one failed, give 40 points over 8 credits, an SGPA of 5.00, even though half your work was flawless. The tool flags any zero-point grade rather than hiding it, because that single row usually explains an average that looks inexplicably low.

Universities differ on what happens next. Some replace the zero once you clear the paper, some keep the original attempt in the cumulative figure, and some drop the credits until the course is passed. If yours excludes failed credits, delete that row and compare the two results; the difference is exactly what clearing the paper is worth to you.

SGPA is one semester. CGPA is the whole degree so far. Almost every application form that says GPA means the cumulative one, so that is usually the number to quote.

They are built the same way, one level apart. SGPA weights courses by credits. CGPA weights whole semesters by the credits each semester carried. This is why adding up your semester results and dividing by the number of semesters gives the wrong answer whenever the semesters differ in size, which they usually do. To do that properly, use the CGPA calculator, which also works out the average you need from the remaining credits to finish on a target.

If your institution reports marks rather than grade points, the marks percentage calculator is the right tool instead, and it handles subjects with different maximums and per-subject pass marks. For the other number that decides whether you can sit the exam at all, there is the attendance calculator. The rest are collected on the calculators hub.
